How do Beijing Residents Value Environmental Improvements in Remote Parts of China
M. Ahlheim, O. Frör, L. Jing, S. Pelz, J. Tong

Advances in Climate Change Research (2013). Vol. 4(25) pp. 190-200

Abstract
The benefits of climate adaptation policy are sometimes underestimated because its nonuse values perceived by people indirectly affected are usually ignored. Using data from a representative sample of Beijing’s urban population, it is shown that people living at a distance perceive nonuse values of climate change adaptation measures aimed at improving the environmental conditions in the Tarim River Basin in Northwest China. Using the contingent valuation method the monetized benefit of a particular set of climate adaptation measures experienced by a Beijing household is approximated. It is concluded that not only the preferences of local people, but also of people living in other parts of China should be considered when deciding if a climate adaptation policy is worthwhile implementing from a social welfare point of view.

A COMPARISON OF TWO FRAMEWORKS FOR KINEMATIC HARDENING IN HYPERELASTO-PLASTICITY
K. Meyer, M. Ekh

Presentations to the XIV International Conference on Computational Plasticity (COMPLAS 2017).

Abstract
In this work we compare two frameworks for thermodynamically consistent hyperelasto-plasticity with kinematic hardening. The first was formulated by Dettmer and Reese (2004), inspired by Lion (2000), and has been used to model sheet metal forming. The second, formulated by Wallin et al. (2003), has been used to model large shear strains and cyclic ratcheting behavior of pearlitic steel (Johansson et al. 2006). In this paper we show that these frameworks can result in equivalent models for certain choices of free energies. Furthermore, it is shown that the choices of free energy found in the literature only result in minor differences. These differences are discussed theoretically and investigated numerically.

Designing healthy communities: Testing the walkability model
A. Zuniga-Teran, B. Orr, R. Gimblett, N. Chalfoun, S. Marsh, D. Guertin, S. Going

Frontiers of Architectural Research (2017).

Abstract
Research from multiple domains has provided insights into how neighborhood design can be improved to have a more favorable effect on physical activity, a concept known as walkability. The relevant research findings/hypotheses have been integrated into a Walkability Framework, which organizes the design elements into nine walkability categories. The purpose of this study was to test whether this conceptual framework can be used as a model to measure the interactions between the built environment and physical activity. We explored correlations between the walkability categories and physical activity reported through a survey of residents of Tucson, Arizona (n =486). The results include significant correlations between the walkability categories and physical activity as well as between the walkability categories and the two motivations for walking (recreation and transportation). To our knowledge, this is the first study that reports links between walkability and walking for recreation. Additionally, the use of the Walkability Framework allowed us to identify the walkability categories most strongly correlated with the two motivations for walking. The results of this study support the use of the Walkability Framework as a model to measure the built environment in relation to its ability to promote physical activity.

Designing healthy communities: A walkability analysis of LEED-ND
A. Zuniga-Teran, B. Orr, R. Gimblett, N. Chalfoun, S. Going, D. Guertin, S. Marsh

Frontiers of Architectural Research (2016).

Abstract
Prevailing city design in many countries has created sedentary societies that depend on automobile use. Consequently, architects, urban designers, and land planners have developed new urban design theories, which have been incorporated into the Leadership in Energy and Environmental Design for Neighborhood Development (LEED-ND) certification system. The LEED-ND includes design elements that improve human well-being by facilitating walking and biking, a concept known as walkability. Despite these positive developments, relevant research findings from other fields of study have not been fully integrated into the LEED-ND. According to Zuniga-Teran (2015), relevant walkability research findings from multiple disciplines were organized into a walkability framework (WF) that organizes design elements related to physical activity into nine categories, namely, connectivity, land use, density, traffic safety, surveillance, parking, experience, greenspace, and community. In this study, we analyze walkability in the LEED-ND through the lens of the nine WF categories. Through quantitative and qualitative analyses, we identify gaps and strengths in the LEED-ND and propose potential enhancements to this certification system that reflects what is known about enhancing walkability more comprehensively through neighborhood design analysis. This work seeks to facilitate the translation of research into practice, which can ultimately lead to more active and healthier societies.

Effects of land and building usage on population, land price and passengers in station areas: A case study in Fukuoka, Japan
X. Zhuang, S. Zhao

Frontiers of Architectural Research (2014). Vol. 3 pp. 199-212

Abstract
This study uses multiple regression to investigate the effects of land and building use on population, land price, and passengers. Initially, we abstract annual data on land and buildings usage within a radius of 0 m–400 m for railway stations and 400 m–800 m for subway stations in Fukuoka, Japan by using the GIS. We then analyze the relationships between 13 factors of land use and 8 factors of building usage, as well as the related population, land price, and passengers using the quantitative expression method. Using several categories of land use and building usage as explanatory variables, we analyze the degree to which the selected categories affect population, land price, and passengers by using the multiple regression method. This research can aid the further development of land and building usage in the future.

Comparative research on different air conditioning systems for residential buildings
X. Zhou, D. Yan, X. Shi

Frontiers of Architectural Research (2017). Vol. 6 pp. 42-52

Abstract
Two types of air conditioning (AC) systems generally exist, namely, centralized and decentralized AC systems. This study focuses on three actual engineering projects of residential communities where centralized AC systems are adopted. The applicability of centralized AC systems in residential buildings is discussed and analyzed. In addition, the key elements that lead to different building energy consumptions and system efficiencies between centralized and decentralized AC systems in residential buildings are investigated. This study shows that in residential buildings, at the point where the centralized feature of the system meets the decentralized feature of users’ load, the problems of high energy consumption and low energy efficiency could easily occur.

Sustainable transportation in the US: A review of proposals, policies, and programs since 2000
J. Zhou

Frontiers of Architectural Research (2000).

Abstract
This paper reviews the research, policy proposals and recommendations, implemented policies, and programs on sustainable transportation since 2000, with regional focus on the US, using the UK (related to the European Union if appropriate), and Canada as references. The paper finds that the concept of sustainable transportation has been given increased attention in all places. There are significant variances between the research, policy proposal, and implementation. Efforts made towards sustainable transportation, and the focus of the efforts at entities within and outside the US also vary notably. As a whole, the US did more research on sustainable transportation than the reference countries and it even undertook several studies of sustainable transportation practices in West Europe. The US federal government is less aggressive than its foreign counterparts in marketing and implementing sustainable transportation. This is evidenced by a lack of overarching federal policy (mandate) on and a universal working definition for sustainable transportation, and absence of a gateway and dedicated website to market and disseminate the idea of sustainable development in general and sustainable transportation in particular.

Materials analysis of traditional Chinese copper halls using XRF and GIS: Kunming Copper Hall as a case study
J. Zhang, W. Chen

Frontiers of Architectural Research (2013). Vol. 2 pp. 74-84

Abstract
This paper presents the framework and results of analysis of the building materials used in traditional Chinese copper halls. The analysis of the Kunming copper hall (KCH) is presented as a typical example. First, the historical building structure of the KCH is investigated. Results of X-ray fluorescence (XRF) spectrometry are presented and analyzed according to the units of each building component. The results indicate that the different components in the same building were cast out of different alloys such as bronze, brass, and red copper. Furthermore, the XRF results are loaded into the geographic information system (GIS) to examine the relations between the building components and their materials. The GIS analysis indicates that the different alloys were deliberately chosen according to the function of each piece in the structure. Finally, the reason and significance of this phenomenon is discussed from the perspective of architectural history and the history of science and technology.

Simulation-based feasibility study of improved air conditioning systems for hospital operating room
Z. Zhai, A. Osborne

Frontiers of Architectural Research (2013). Vol. 2 pp. 468-475

Abstract
The goal of the air distribution inside a hospital operating room (OR) is to protect the patient and staff from cross-infection while maintaining occupant comfort and not affecting the facilitation of surgical tasks. In ORs, HEPA-filtered air and vertical (downward) laminar airflow are often used to achieve a unidirectional flow of fresh air from ceiling, washing over the patient and flowing out of exhaust vents on the side walls, near the floor. However, previous research has shown that this method does not necessarily achieve the desired unidirectional flow pattern or adequately achieve optimal air asepsis. The results from this study show that maximizing the area of the laminar flow diffusers remedies this issue and provides very low contamination levels. The use of air curtains as specified by manufacturers of commercial products may not provide satisfactory results, with noticeable contamination levels at the wound site.

Landscape transition of historic villages in Southwest China☆?>
Y. Yu

Frontiers of Architectural Research (2013). Vol. 2 pp. 234-242

Abstract
The environment in villages in Southwest China has been experiencing constant changes, indicating related change-inducing factors as well as their constitution and hierarchy. Starting from the classification of built environment according to Rapoports view, the “environment” consists of fixed, semi-fixed and unfixed elements (A. Fixed-feature elements: infrastructure, buildings, walls, floors, etc. B. Semi-fixed-feature elements: “furnishings” of the environment, interior or exterior, trees and gardens, fences, signs, billboards, lights, etc. C.Unfixed-feature elements: typically people and their activities, behaviors, etc.). Five representative historic villages in Southwest China (Zhenshan Village in Guizhou, Zhanglang Village in Yunnan, Moluo Village in Sichuan, Huaili Village in Guangxi, and Gongzhong Village in Tibet) were investigated to demonstrate the changes in terms of landscape in the last decade. This article provides an analysis of the dialectical relationship between reservation practices and evolving landscapes from a diachronic perspective. This analysis reveals defects of heritage conservation projects for historic villages in Southwest China. The results indicate the following: (1) there exists an important relationship between unfixed-feature elements of landscape and cultural heritages in historic villages, (2) semi-fixed-feature elements, although being neglected in most preservation practices, show strong sensitivity to mass tourism, (3) fixed-feature elements are highly vulnerable to civil engineering techniques, and (4) the most active change-inducing factors for evolving landscapes in historic villages include value orientations of villagers, relative locations of villages, ethnic groups, customs, and economic development. In conclusion, approaches to promoting sustainable development of historic village in Southwest China are explored.

Healthy campus by open space design: Approaches and guidelines
S. Lau, Z. Gou, Y. Liu

Frontiers of Architectural Research (2014). Vol. 3 pp. 452-467

Abstract
This paper examines the architectural and landscape design strategies and intentions for green, open spaces facilities targeting stress alleviation for learning environments such as those of university campuses in a compact urban setting. Literature reviews provide three prevailing perspectives for physical design pedagogical operatives: healing gardens where greenery and plants produce restorative effects, flexible spaces that accommodate functional needs of different activities, and green buildings that incorporate open space as a catalyst for integrated eco-system. Corresponding design approaches (landscape design, spatial design and green design) are scrutinized by case study. A comparison of two university campuses with different urban contexts is conducted to identify challenges and opportunities for applying these design approaches. For a compact campus, high-dense surroundings may limit the size of an open space and may handicap circulation and accessibility, on the other side, a small open space may provide its users more intimate contact with natural restorative elements and also a more controllable microclimate for physical comfort. A healthy campus should encompass diverse open spaces to satisfy different purposes. Finally, a framework that integrates the three approaches is combined to produce a sustainable design rubric.

Experimental study of the isothermal sorption properties of late Qing and 1980s grey bricks in Wujiang, Suzhou, China
L. Yonghui, H. Xie, J. Wang, X. Li

Frontiers of Architectural Research (2013). Vol. 2 pp. 483-487

Abstract
Grey brick is a key material in Chinese traditional architecture. The isothermal sorption curve of grey bricks is one of the basic moisture characteristics for studying the heat transfer of brick building enclosure structures and is also a fundamental parameter of research into the degradation mechanisms of Chinese traditional architecture. In this study, we measure the isothermal sorption curves of Wujiang (Suzhou, China) bricks from the 1980s and the late Qing period, by applying constant relative humidity controlled by saturated salt-water solutions under isothermal conditions. We then present their fitting formulas for humidity bound ranges of 5−92%. The results indicate that samples of the same-area traditional Suzhou grey bricks from different time periods show relatively large differences in their isothermal sorption properties, with the isothermal sorption property values of the late Qing grey bricks about three times those of the 1980s grey bricks.

Reyner Banham and modern design culture
B. Wiryomartono

Frontiers of Architectural Research (2012).

Abstract
What is modernity in architecture? In English speaking world, the question is likely impossible to answer without considering the works of Peter Reyner Banham (1922–1988). Regardless of his polemist and disparaging style in his critical writings, this study argues that Banham offers a constructive renewal for the body of knowledge on history and theory of modernity in architectural design. Accordingly, he posits and disposes architectural profession with scientific and technological vision in the front line of struggle for environmental betterment. For him modernity in architecture comprises triad components: function, technology, and aesthetics by which historical milestones come into being. A study on Banhams engagement with modernity is considerably necessary regarding his conviction that history of architecture happens as the consequence of interactions of technological innovations and design creativities, and in response to socioeconomic circumstances as well.

People as place-making coordinate: A methodology for visualizing personal spaces
G. Ivanovic

Frontiers of Architectural Research (2014). Vol. 3 pp. 36-43

Abstract
The present research introduces the Activity Counter Maps (ACM) as a methodology for visualizing peoples social spaces, arguing that accurate representations of these spaces are crucial for understanding the role of human activity as a place-making coordinate. The ACM were tested in two case studies conducted in Ueno Park (Tokyo). The first case study is focused on the visualization of the intensity of activity in the totality of the park. The second case study is focused in two sub-places of the park, generating representations of peoples personal spaces combined into a three-dimensional “Common social space”. The research concludes with the analysis of the generated visualizations and their potential for incorporating place-variables into the digital design process.

Landscape characteristic aesthetic structure: Construction of urban landscape characteristic time-spatial pattern based on aesthetic subjects
M. Wang, B. Yu

Frontiers of Architectural Research (2012). Vol. 1 pp. 305-315

Abstract
The paper presents means and models of city-landscape characteristic structure construction on the aspect of landscape aesthetics subjects, which is called the landscape characteristic aesthetic structure and in short as LCAS. In this paper, the steps of LCAS research are as follows: Describes the concepts of the landscape characteristic aesthetic structure (LCAS), and expounds the LCAS properties: systematic quality, temporal and spatial quality, and virtual existence. Learns from typology research methods, discusses the elements and types needed in a landscape characteristic aesthetic system, and constructs research method for LCAS pattern. As for the temporal dimension, the dynamic evolution and interaction expressed in LCAS between the “tradition” and “modernity” landscapes conflict. As for the spatial dimension, this paper explores the LCAS patterns in macroscopic scope of city group, the middle scope of single cities and the microcosmic scope of urban spaces with questionnaires and examples research. Uses pattern language to express different LCAS types in the temporal and spatial system. We develop the patterns of various LCAS types with graphical patterned representation, as well as construct the LCAS research method and theory which is based on the general peoples aesthetic standards and sensibilities to build city characteristics and urban landscapes as a guidance.

Location choice of Chinese urban fringe residents on employment, housing, and urban services: A case study of Nanjing
X. Wang, P. Hu, Y. Zhu

Frontiers of Architectural Research (2016).

Abstract
Urban fringe area is the most important space for city development. It includes several complicated elements, such as population, space, and management organization. On the basis of local population attributes in the city fringe area combined with people’s movement characteristics in time and space, this article reclassifies basic public service facilities and discusses the relationship between facility layout and housing, employment, and commuter transportation. Through a questionnaire survey in Qiaobei District of the urban fringe area in Nanjing and on the basis of comparative analysis, we discuss the impact factor on the choice of housing, urban services, and the tolerance of commuting time. Our findings indicate mutual promoting and restricting connections among living, employment, and services. Workers’ living situation determines their daily behavior, such as dining, shopping, and entertainment. Furthermore, different income levels have a great influence on residents’ choices with regard to places to live and develop their careers.

Restructuring surface tessellation with irregular boundary conditions
T. Wang, R. Krishnamurti, K. Shimada

Frontiers of Architectural Research (2014). Vol. 3 pp. 337-347

Abstract
In this paper, the surface tessellation problem is explored, in particular, the task of meshing a surface with the added consideration of incorporating constructible building components. When a surface is tessellated into discrete counterparts, certain unexpected conditions usually occur at the boundary of the surface, in particular, when the surface is being trimmed. For example, irregularly shaped panels form at the trimmed edges. To reduce the number of irregular panels that may form during the tessellation process, this paper presents an algorithmic approach to restructuring the surface tessellation by investigating irregular boundary conditions. The objective of this approach is to provide an alternative way for freeform surface manifestation from a well-structured discrete model of the given surface.

Parametric study on the performance of green residential buildings in China
X. Wang, H. Altan, J. Kang

Frontiers of Architectural Research (2015). Vol. 4 pp. 56-67

Abstract
The parametric study of the indoor environment of green buildings focuses on the quantitative and qualitative improvement of residential building construction in China and the achievement of indoor thermal comfort at a low level of energy use. This study examines the effect of the adaptive thermal comfort of indoor environment control in hot summer and cold winter (HSCW) zones. This work is based on a field study of the regional thermal assessment of two typical cases, the results of which are compared with simulated results of various scenarios of “energy efficiency” strategy and “healthy housing” environmental control. First, the simulated results show that the adaptive thermal comfort of indoor environment control is actually balanced in terms of occupancy, comfort, and energy efficiency. Second, adaptive thermal comfort control can save more energy for heating or cooling than other current healthy housing environmental controls in China׳s HSCW zone. Moreover, a large proportion of energy use is based on the subjective thermal comfort demand of occupants in any building type. Third, the building shape coefficient cannot dominate energy savings. The ratio of the superficial area of a building to the actual indoor floor area has a significant positive correlation with and affects the efficiency of building thermal performance.

Revolution of Chinese architectural design at the new-type urbanization stage
J. Wang

Frontiers of Architectural Research (2015). Vol. 4 pp. 248-250

Abstract
Witnessing more than three decades of sustained and rapid economic growth, China has become a nation that enjoys the fastest rate of urbanization, the largest quantities of civil construction, the most obvious urban development to be “newer”, “bigger” and “higher”, and the most prosperous architectural design market worldwide. In terms of the construction industry, housing construction totals 31.3 billion square meters, occupying more than 70% of the floor area of the existing stock houses. It is safe to say that the construction industry significantly boosts GDP growth, expands the number of jobs, and improves the living conditions of the masses. Related to this is the need to end the architectural guidelines of the planned economy era economizing on food and clothing and instead step into a new historic stage allowing bold pursuit of architectural aesthetics and individuality. A group of architects who have social ideals, adhere faithfully to professional standards and pledge to pursue architectural innovation are active in China. Instead of simply converting the overwhelming opportunities brought to carry economic benefits, they dare to embrace the challenges imposed on enhancing architectural connotation and create a batch of high-level work that lives up to expectations of the era, marking the achievement of reform and rapid urbanization in China. Yet, as time goes on, the promotion of national development concepts, ideas of social consumption and the masses’ cultural level establishes new requirements for the architectural design industry, architects and architectural design works. An appeal is thus made against Chinese architects for a summary, reflection and proactive anticipation to respond to the new requirements of the era.

Frontiers of Architectural Research (2014).

Abstract
More than 60% of older Americans have sedentary lifestyles1 and are recommended more physical activities for health benefit. Nearby outdoor environments on residential sites may impact older inhabitants׳ physical activities there (defined as walking, gardening, yard work, and other outdoor physical activities on residential sites). This study surveyed 110 assisted-living residents in Houston, Texas, regarding their previous residential sites before moving to a retirement community and physical activities there. Twelve environmental features were studied under four categories (typology, motivators, function, and safety). Based on data availability, a subset of 57 sample sites was analyzed in Geographic Information Systems. Hierarchical linear modeling was applied to estimate physical activities as a function of the environments. Higher levels of physical activity were found to be positively related with four environmental features (transitional-areas, connecting-paths, walk-ability, and less paving).

The “narrative sincerity” in museums, architectural and archaeological restoration of Franco Minissi
B. Vivio

Frontiers of Architectural Research (2015). Vol. 4 pp. 202-211

Abstract
The Italian historiography of the architecture of the second half of the Twentieth century has not given due weight to the dialectic qualities of work of Franco Minissi on ancient structures. He became known for the debate on the use of innovative materials in archaeological sites and not for the extent of his contributions. The world do not know his museums, Italian and not, his many conservation and restoration projects, his archaeological parks, redevelopments of historic centres, new buildings, interior design projects, shops and exhibitions. A reading of his museological works alongside of his experiments on archaeological sites, can help highlight the conceptual congruence with which Minissi tried to meet the needs of the present and the preservation of antiquities, as a dialogue with the past, of refined sensibility and intended to a reversibility respectful of preexistence. This places him among the key figures of the origins of the critical restoration, as an inspiration that continues to offer fruitful ideas to the new generations.

The evolving role of evidence-based research in healthcare facility design competitions
S. Verderber, S. Jiang, G. Hughes, Y. Xiao

Frontiers of Architectural Research (2014). Vol. 3 pp. 238-249

Abstract
The architectural design competition remains a widely accepted method to advance design innovation, creativity, theoretical discourse, and the profession. In the realm of healthcare facility design, by contrast, clients and their sponsoring organizations seldom utilize this method. The reasons for this are many, and continue to stand in stark contrast to a growing body of evidence-based research and design (EBR&D)that is potentially of value in improving performance-based dimensions—esthetic and otherwise—of healthcare facilities globally. A comparative analysis of the entrants to a recent U.S. completion was conducted. Based on the results of this analysis, a two-phased healthcare facility design competition paradigm is put forth that is premised on the assumption that the intuitive dimensions of design creativity can be further advanced by means of a well timed and thoughtful injection of quantitatively based knowledge pertaining to patient, family, staff, and organizational concerns and priorities. This proposal׳s limitations, and future opportunities, are discussed.

Frontiers of Architectural Research (2016). Vol. 5 pp. 412-424

Abstract
The disappearance of vernacular buildings is a common phenomenon worldwide and in Indonesia. The Banjarese house, a type of Indonesian vernacular architecture, is a typical riverside dwelling that shows the strong relationship between the river and the inhabitants. In view of the number of Banjarese houses facing degradation as a riverside type of vernacular architecture, a study is necessary. The characteristics of the inhabitants must be considered when observing the condition of the remaining houses. Therefore, this study aims to investigate the influence of inhabitant background on the physical changes of Banjarese houses for future revitalization. A research was conducted in the embryo of Banjarmasin along the Kuin riverside settlement in Kuin Utara sub-district through a door-to-door survey with a questionnaire. The exploration indicates the following: (1) the original form of all remaining houses has been altered, (2) most of the inhabitants are classified as a low-income society, (3) the different characteristics of the present inhabitants change the physical condition of houses, (4) the relationship of the current house condition to the socio-culture and economy of the inhabitants plays a prominent role in revitalizing Banjarese houses as a valuable asset.
Abstract
The disappearance of vernacular buildings is a common phenomenon worldwide and in Indonesia. The Banjarese house, a type of Indonesian vernacular architecture, is a typical [...]

Preservation initiatives for the truncated pyramid-shaped traditional houses of Siirt, Turkey
C. Akın, A. Bekleyen, M. Yıldırım

Frontiers of Architectural Research (2016). Vol. 5 pp. 360-370

Abstract
The traditional houses of the residential areas in and around Siirt in the southeastern region of Turkey are notable because of their interesting forms. The most successful examples are the "truncated pyramidal-shaped houses" that have existed for centuries and are unique to the locality, however, these forms are demolished rapidly. In this study, the structures of small-scale settlements in Siirt province and its environs have been evaluated to highlight the cultural aspects of the region. The subject of this research is to investigate the design principles of the rural houses constructed in vernacular style to raise international awareness of the need to preserve vernacular architecture. Surviving examples have been examined in terms of multiple case approach by their forms, spatial compositions, changes in their forms over time, their layouts in urban and rural areas, the construction techniques used to produce them from material production through implementation, the composition of the living space and its uses, their differences or similarities to other houses in the region and their aesthetic details. The research reveals that the design principles of traditional rural architecture offer the use of local material and techniques in a unique way that promote highlights to the future.

Method for the proposal and evaluation of urban structures for compact cities using an expert system
S. Tsuboi, S. Ikaruga, T. Kobayashi

Frontiers of Architectural Research (2016). Vol. 5 pp. 403-411

Abstract
The world population is continually increasing, but the Japanese population is decreasing. By 2050, the Japanese population is calculated to be close to 100 million people, and by 2060, 40% of the Japanese are estimated to be aged 65 years or more. Data show an increase in the declining birth and aging rates of the population. The development of high-concentration urban structures will be needed to solve such problems. However, a detailed vision of the future is yet to be clarified and in the process of consideration. In this study, we developed an instrument called “Population Migration Tool, ” which is based on plural planning and policy, after we formed a future population distribution model. In addition, We also established a high-concentration urban structure model with this tool with the aim of considering the kind of urban structure local cities should target in the future.

Comparison of thermal performance between test cells with different coverage systems for experimental typical day of heat in Brazilian Southeastern
G. Cardoso, F. Vecchia

Frontiers of Architectural Research (2014). Vol. 3 pp. 271-282

Abstract
This article shows experimentally the thermal performance of two test cells with different coverage systems, Light Green Roof (LGR) and ceramic roof by analyzing internal surface temperatures (IST) in the ceiling and dry bulb temperatures (DBT). The objective was to evaluate the spatial distribution of temperatures in buildings according to spatial and temporal Dynamic Climatology approaches. An experimental, typical day for heat conditions was determined. The data of the main climatic variables provided by an automatic weather station and temperatures inside the test cells were collected using thermocouples installed such that the entire space is included. The results led to the conclusion that the LGR has a balanced IST and DBT spatial distribution compared with ceramic roofs. Nevertheless, the analysis of the thermal performance is only one of the variables that must be considered when developing a construction proposal that is adapted to the context. The manner in which the thermocouples were placed inside the test cells also showed the importance of specifying the location of the sensors in experimental studies on the behavior and thermal performance of buildings.

Rigid foam polyurethane (PU) derived from castor oil (Ricinus communis ) for thermal insulation in roof systems
G. Cardoso, S. Neto, F. Vecchia

Frontiers of Architectural Research (2012). Vol. 1 pp. 348-356

Abstract
This paper discusses the response of the thermal insulation lining of rigid foam polyurethane (PU) derived from castor oil (Ricinus communis ) in heat conditions, based on dynamic climate approach. Liners have been widely used, because the coverage of buildings is responsible for the greatest absorption of heat by radiation, but the use of PU foam derived from this vegetal oil is unprecedented and has the advantage of being biodegradable and renewable. The hot wire parallel method provided the thermal conductivity value of the foam. The thermogravimetric analysis enabled the study of the foam decomposition and its lifetime by kinetic evaluation that involves the decomposition process. The PU foam thermal behavior analysis was performed by collecting experimental data of internal surface temperature measured by thermocouples and assessed by representative episode of the climatic fact. The results lead to the conclusion that the PU foam derived from castor oil can be applied to thermal insulation of roof systems and is an environmentally friendly material.

Supply of condominiums in central district of Okayama City and Kyoto City
P. Tang

Frontiers of Architectural Research (2012). Vol. 1 pp. 178-185

Abstract
Most of the local cities of Japan are suffering from the depopulation in central district (C.D.). In Okayama city, the government had induced some strategies such as supply more condominiums for local revitalization since 2000. From the Basic Resident Register of Okayama, the population in C.D. Okayama has increased recently. This study has the goal to clarify the situation of condominium supply in this district by an investigation. Compared with the result of a same survey in C.D. Kyoto, the following findings are confirmed: population recovery is happening in the central district in both of the 2 cities. The dimension of the condominiums in Okayama is larger than that in Kyoto. The average dimension of the condominiums in Okayama is 14 stories building with 61 units of 110 m2 . Contrastingly, that in Kyoto is 11 storied building with 59 units of 82 m2 . Most of the condominiums in C.D. Kyoto are located closely to the railway or subway station, while those in C.D. Okayama are randomly located, because of the high dependence of automobile traffic. The previous usages of the sites of condominiums in Okayama are parking, housing and financial institute, and in Kyoto they are parking, shop or business building.

Using passive cooling strategies to improve thermal performance and reduce energy consumption of residential buildings in U.A.E. buildings
H. Taleb

Frontiers of Architectural Research (2014). Vol. 3 pp. 154-165

Abstract
Passive design responds to local climate and site conditions in order to maximise the comfort and health of building users while minimising energy use. The key to designing a passive building is to take best advantage of the local climate. Passive cooling refers to any technologies or design features adopted to reduce the temperature of buildings without the need for power consumption. Consequently, the aim of this study is to test the usefulness of applying selected passive cooling strategies to improve thermal performance and to reduce energy consumption of residential buildings in hot arid climate settings, namely Dubai, United Arab Emirates. One case building was selected and eight passive cooling strategies were applied. Energy simulation software – namely IES – was used to assess the performance of the building. Solar shading performance was also assessed using Sun Cast Analysis, as a part of the IES software. Energy reduction was achieved due to both the harnessing of natural ventilation and the minimising of heat gain in line with applying good shading devices alongside the use of double glazing. Additionally, green roofing proved its potential by acting as an effective roof insulation. The study revealed several significant findings including that the total annual energy consumption of a residential building in Dubai may be reduced by up to 23.6% when a building uses passive cooling strategies.

Improvement of thermal environment and reduction of energy consumption for cooling and heating by retrofitting windows
M. Takashi, H. Shuichi, O. Daisuke, T. Masahiko, S. Jun

Frontiers of Architectural Research (2013). Vol. 2 pp. 1-10

Abstract
Various techniques for creating a comfortable thermal environment and saving energy have been proposed and employed in residential buildings in many countries, including Japan. For these techniques to be introduced, existing houses should be renovated. Among the techniques available, installation of additional inner windows is effective in creating a comfortable and energy-efficient living environment. In the present research, the effect of additional inner windows on the thermal environment and energy saving was investigated by measuring indoor climates. Windows were renovated in two rooms on the fourth floor of a four-story reinforced concrete building. Air temperatures, the humidity, the global solar radiation on horizontal and vertical surfaces, radiant temperatures, and the electricity consumption of air-conditioners were measured. A comparison of these values before and after the installation of inner-windows showed that the thermal environment and energy saving had improved. Results obtained from a thermal model agreed well with measured results by changing the value of solar transmittance and heat transmission coefficient of the glazing following renovation. Furthermore, in a questionnaire survey conducted in summer, more than half of the occupants answered “comfortable” to a question on the overall thermal comfort.

Wind comfort in a public urban space—Case study within Dublin Docklands
Á. Szűcs

Frontiers of Architectural Research (2013). Vol. 2 pp. 50-66

Abstract
Open public spaces provide venues for cultural, recreational events and promote informal social contact between citizens. Successful outdoor spaces promote comfort and invite people to stay outdoors. Provision of thermal comfort outdoors present a challenge, as an extended range of environmental conditions must be dealt with. The present study examines whether climatic characteristics in Dublin facilitate exercising long-term outdoor activities during summer, and investigates the extent to which urban planning and the resulting urban morphology of the built environment influences microclimates created, from the viewpoint of wind environment. Microclimates at Grand Canal Square have been simulated by ENVI-met. Wind velocity has been expressed in relation to that of the “background” climate in order to verify if the site has a wind protecting character or to the contrary, it enhances airflow. The results show for the dominant wind directions (W, SW, S) that 60% higher wind velocity than at Dublin Airport can occur around building corners and at restricted flow sections—preventing any kind of long-term outdoor activity during a “typical” day. S and SW winds cause 15%–20% acceleration at the W waterfront area. Windy urban environment can call forth a limited frequentation of urban space.

Differences in spatial understanding between physical and virtual models
L. Sun, T. Fukuda, T. Tokuhara, N. Yabuki

Frontiers of Architectural Research (2014). Vol. 3 pp. 28-35

Abstract
In the digital age, physical models are still used as major tools in architectural and urban design processes. The reason why designers still use physical models remains unclear. In addition, physical and 3D virtual models have yet to be differentiated. The answers to these questions are too complex to account for in all aspects. Thus, this study only focuses on the differences in spatial understanding between physical and virtual models. In particular, it emphasizes on the perception of scale. For our experiment, respondents were shown a physical model and a virtual model consecutively. A questionnaire was then used to ask the respondents to evaluate these models objectively and to establish which model was more accurate in conveying object size. Compared with the virtual model, the physical model tended to enable quicker and more accurate comparisons of building heights.

A synchronous distributed cloud-based virtual reality meeting system for architectural and urban design
L. Sun, T. Fukuda, B. Resch

Frontiers of Architectural Research (2014). Vol. 3 pp. 348-357

Abstract
In the spatial design fields such as architectural design and urban design, a consensus-building process among a variety of stakeholders like project executors, architects, residents, users, and general citizens is required. New technological developments such as cloud computing and Virtual Design Studios (VDS) enable the creation of virtual meeting systems. This paper proposes an approach towards a synchronous distributed design meeting system. In this paper, in addition to sharing a 3D virtual space for a synchronous distributed type design meeting, we developed a prototype system that enables participants to sketch or make annotations and have discussions as well as add viewpoints to them. We applied these functions to evaluate an architectural design and urban landscape examination. In conclusion, the proposed method was evaluated as being effective and feasible. Yet, it shows a few shortcomings including the fact that simultaneous operation is limited to one client, and more arbitrary shapes should be supported in future versions of the application.

Study on the correlation between the hierarchical urban system and high-speed railway network planning in China
H. Sun

Frontiers of Architectural Research (2016). Vol. 5 pp. 301-318

Abstract
This study examines the interrelatedness between the hierarchical structure of China׳s urban system and high-speed railway (HSR) network planning at the national level. As a multi-layered system, the Chinese HSR can be categorized into three sub-networks, namely, the national HSR trunk network, the national HSR extensional network, and the intercity HSR network. By examining the direct HSR network connection, HSR nodal connection, and HSR operational frequency of 287 prefecture-level cities, this study demonstrates that the hierarchies of China׳s administrative, demographic, and economic urban systems strongly influence HSR network planning. The national HSR trunk network prioritizes the connection of top-level central cities, whereas the extensional network prioritizes cities at the lower level of the urban system. Moreover, the national HSR system forms the backbone of the HSR network structure based on a national scale, whereas the intercity HSR system satisfies the travel needs within urban agglomerations based on the regional level.

Breathing architecture: Conceptual architectural design based on the investigation into the natural ventilation of buildings
A. Stavridou

Frontiers of Architectural Research (2015). Vol. 4 pp. 127-145

Abstract
This study explores architectural design by examining air, fluid mechanics, and the natural ventilation of buildings. In this context, this research introduces a new way of dealing with the process of architectural synthesis. The proposed way can be used either to create new architectural projects or to rethink existing ones. This study is supported by previous investigation into the natural ventilation of buildings via computational and laboratory simulation (Stavridou, 2011, Stavridou and Prinos, 2013 ). The investigation into the natural ventilation of buildings provides information and data that affect architectural design through various parameters. The parameters of architectural synthesis that are influenced and discussed in this paper are the following: (i) inspiration and analogical transfer, (ii) initial conception of the main idea using computational fluid dynamics (digital design), (iii) development of the main idea through an investigatory process toward building form optimization, and (iv) form configuration, shape investigation, and other morphogenetic prospects. This study illustrates the effect of natural ventilation research on architectural design and thus produces a new approach to the architectural design process. This approach leads to an innovative kind of architecture called “breathing architecture.”

Evaluation of fitness of design in urban historical context: From the perspectives of residents
H. Sotoudeh, W. Abdullah

Frontiers of Architectural Research (2013). Vol. 2 pp. 85-93

Abstract
Historic city cores in many countries either fell into neglect or suffered from harmful developments. Due to a variety of reasons, conservation projects failed to preserve socio–cultural assets of historic environments. One of these reasons is that experts who involve in the development of historical context completely disregard the communities in such historic areas or their inhabitants. This paper looks into residents' preferences on infill design projects as part of urban development in historical contexts. It aims to investigate preference ratings of those residents who live in urban historical context in terms of the quality of new infill design and its relationship to the historical surroundings. This research attempts to evaluate the best design strategies from the point view of the residents as well as the effects of cognitive properties on their preferences. Methodologically, a case study approach was adopted with 204 residents as participants in this survey. The contributive elements that are essential to the quality of fitness are identified through quantitative analysis. The findings of this research indicate that the most preferred design strategies are “Literal Replication” and “Invention within Style” from the perspective of the residents, who prefer, to a greater degree, new buildings in historical context replicating something from their surroundings. These findings are useful to experts and major organisations to conduct successful infill development, with consideration of the perceptions of the residents on the changes in their historical context.

Thermal upgrading of Hui-style vernacular dwellings in China using foam concrete
X. Shi, W. She, H. Zhou, Y. Zhang, F. Shi, W. Chen

Frontiers of Architectural Research (2012). Vol. 1 pp. 23-33

Abstract
Architectural heritage conservation is an important field in architectural research. The Hui-style vernacular dwelling is an essential architectural heritage of China. Its hollow wall system, with horsehead-like upper corners, is a distinct architectural feature that is worth preserving. However, the thermal performance of the hollow wall is relatively poor by todays standard. The current study developed a novel approach, whereby foam concrete was used to fill the voids inside the hollow wall to improve its thermal resistance. This approach was deemed cost effective, easy to learn, and capable of preserving the architectural integrity of the wall. Different types of foam concrete were prepared and tested. Testing results showed that the material properties of foam concrete are suitable for thermally upgrading the hollow wall system. Climate chamber testing was conducted to investigate the effectiveness of the proposed thermal upgrading strategy. The testing results suggested that filling the voids with foam concrete can effectively improve the overall thermal resistance of the hollow wall system by 24%, which is almost equal to the overall thermal resistance when using the more expensive commercial inorganic stucco system.

According to the information of 231 cultural and creative industry parks on the Internet literature, this research classified and studied the park elements from the text using the method of semantic Ontology analysis. The paper analyzes the cultural and creative industry park in the performance of type, constitution elements of geographical attributes, characteristics, etc. Through analysis, we found that “location”, “form” and “rhetoric” are frequently mentioned in the park names. As the parks prefer to combine cultural relics with their own characters for highlighting influence and specialties, the park locations also have certain restrictions (e.g., “historic sites”, “ancient cities”). Furthermore, cultural and creative industry parks cover a wide range of contents (e.g., “digital industry”, “ecological landscape”). The boundaries of the park type and content are not very clear in present China. And, the parks lack of overall planning and often have an imperfect industrial chain and other issues. Therefore, on developing cultural and creative industry parks, the overall planning and perfect industrial chain need to be focused on.

Algorithm for constructing an optimally connected rectangular floor plan
K. Shekhawat

Frontiers of Architectural Research (2014). Vol. 3 pp. 324-330

Abstract
In most applications, such as urbanism and architecture, randomly utilizing given spaces is certainly not favorable. This study proposes an explicit algorithm for utilizing the given spaces inside a rectangle with satisfactory results. In the literature, connectivity is not considered as a criterion for floor plan design, but it is deemed essential in architecture. For example, dining rooms are preferably connected to kitchens, toilets should be connected to many rooms, and each bedroom should be separated from the other rooms. This paper describes adjacency among spaces and proves that the obtained rectangular floor plan is one of the best ones in terms of connectivity. An architectural and mathematical object called extra spaces is introduced by the proposed algorithm and is subsequently examined in this work.

Urban greenways: Operationalizing design syntax and integrating mathematics and science in design
A. Sharma

Frontiers of Architectural Research (2015). Vol. 4 pp. 24-34

Abstract
The ubiquitous sameness of urban greenways prompts questions on generative design grammar and syntax, whether creative, critical rethinking at that level might be lacking. However the design syntax of urban greenways is not explicitly discussed thus leaving a critical gap in knowledge. This paper begins tackling the larger question by acting on the fundamental subset of it, by operationalizing the design syntax of urban greenways. This is done through mathematics-based graph studies to analyze patterns and shapes, photography based thermal, material and morphology studies, and section analyses to make imagery-derived deductions on the design syntax. Recommendation on approaches to diversify and enrich the design syntax includes a more direct reference from ecosystem science theories such for siting and planning the urban greenways at macro- to meso-scale, a mixed-method approach, combining mathematics, photography and drawings based frames for analyses at meso-, to micro-scale, and a turtle view scale for designing at meso- to micro-scale, with an emphasis on latter.

Recent innovations in modern architectural technology facilitated the development and widespread utilisation of sustainable commercial buildings for sustainable social development. In this research, commercial architecture in Australia is demonstrated as a basis for determining how sustainable technology could be controlled and what the eco-maintenance and materials of major building elements should be. This research also analyzes and describes the sustainable commercial architecture background in Australia. A widely integrated approach is employed in the critical process of general architectural design because commercial buildings must integrate sociology, architecture, and aesthetics.

Visual language in Mamluk architecture: A semiotic analysis of the Funerary Complex of Sultan Qaitbay in Cairo
N. Ramzy

Frontiers of Architectural Research (2013). Vol. 2 pp. 338-353

Abstract
Cultural background plays a significant role in the sphere of visual art. Semiotics as a discipline is recognized as a useful tool in gauging cultural background and identifying signs that might represent the message of a certain work. Given the rich cultural context of Mamluk architecture, this form of art can be used in studying semiotics. Semiotic tools were employed to interpret the expression of architectural forms and to formulate a subsequent understanding of these architectural forms by turning each element into a communication tool that elucidates meaning. The Sufie tradition was the dominant Islamic practice during the Mamluk period, during which metaphysics, numbers, and geometry were regarded as indispensable tools in manifesting the nature of divinity and the order of being. A semiotic reading of the Funerary Complex of Sultan Qaitbay in Cairo, regarded as one of the perfect works of this era, was proposed to study the reflections of these notions on architectural works. Several messages were embodied in the building, such as functional or technical messages. The semiotic reading in this study is solely concerned with the spiritual message of the building.

Abstract
The planning process in a planning studio demonstrates a microcosm of diverse concepts of ideologies and identities seeking acknowledgment and spatial recognition. In the modern world of multiple and dynamic identities and ideologies, aspiring for the self-recognition of regions, towns, and communities, a place-based identity has become a core aspect that needs to be taken into planning consideration. The analytic planning method used is iterative of both top–down and bottom–up approaches, thereby creating multi-dimension and coherent planning alternatives where spatial solutions arise from communities along their changing processes. We present two spatial alternative plans that were developed in the studio course and are based on this line of thinking. Results were very dynamic aspiring complex plans, which are also highly applicable and flexible, thereby addressing a wide range of ideologies and identities.

Assessment of the effect of modern transformation on the traditional settlement ‘Ksar’ of Ouargla in southern Algeria
M. Sebti, D. Alkama, A. Bouchair

Frontiers of Architectural Research (2013). Vol. 2 pp. 322-337

Abstract
The architecture of the Ouargla Ksar has long been recognized as an example of adaptation to harsh climate in the deep desert of Algeria. Over the last few decades, it has undergone some changes in its initial urban structure, due to accelerated and uncontrolled modern urbanization, that had negative implications and devaluation of its thermal characteristics. This article tries to understand the bioclimatic concept of adaptation of this Ksar and assess to what extent its morphological transformation has impacted its microclimatic conditions. This assessment is made through a comparative study between two different areas: one untransformed and the other transformed. A referential weather station situated in the suburbs was also exploited for consolidation of comparison. The investigation was undertaken using site measurements and observations.

Frontiers of Architectural Research (2013). Vol. 2 pp. 121-133

Abstract
Due to the climate change debate, a lot of research and maps of external climate parameters are available. However, maps of indoor climate performance parameters are still lacking. This paper presents a methodology for obtaining maps of performances of similar buildings that are virtually spread over whole Europe. The produced maps are useful for analyzing regional climate influence on building performance indicators such as energy use and indoor climate. This is shown using the Bestest building as a reference benchmark. An important application of the mapping tool is the visualization of potential building measures over the EU. Also the performances of single building components can be simulated and mapped. It is concluded that the presented method is efficient as it takes less than 15 min to simulate and produce the maps on a 2.6 GHz/4 GB computer. Moreover, the approach is applicable for any type of building.

Abstract
The Mughal settlements are an integral part of Old Dhaka. Uncontrolled urbanization, changes in land use patterns, the growing density of new settlements, and modern transportation have brought about rapid transformation to the historic fabric of the Mughal settlements. As a result, Mughal structures are gradually turning into isolated elements in the transforming fabric. This study aims to promote the historic quality of the old city through clear and sustainable integration of the Mughal settlements in the existing fabric. This study attempts to analyze the Mughal settlements in old Dhaka and correspondingly outline strategic approaches to protect Mughal artifacts from decay and ensure proper access and visual exposure in the present urban tissue.

Considering functional dimensioning in architectural design
J. Savoini, Z. Lafhaj

Frontiers of Architectural Research (2017). Vol. 6 pp. 89-95

Abstract
This paper presents an overview of the functional dimensioning (FD) concept applied to the construction sector. FD addresses the issue of tolerance, construction involves several trades working together while each trade has its own construction tolerances. To investigate this problem, three case studies are investigated. The first one describes a classic case of a window in a bay and the way constructors solved the resulting tolerance problems. The second case study describes the notion of chain dimension. The last case study presents the notion of wedge as a solution to solve problems related to tolerance gap accumulation. This paper is of interest to the scientific community that is working to industrialize the construction sector and also to architects (in the design), construction managers (onsite), and manufacturers (construction trades).

Assessment of energy utilization and leakages in buildings with building information model energy
E. Samuel, E. Joseph-Akwara, A. Richard

Frontiers of Architectural Research (2017). Vol. 6 pp. 29-41

Abstract
Given the ability of building information models (BIM) to serve as a multidisciplinary data repository, this study attempts to explore and exploit the sustainability value of BIM in delivering buildings that require less energy for operations, emit less carbon dioxide, and provide conducive living environments for occupants. This objective was attained by a critical and extensive literature review that covers the following: (1) building energy consumption, (2) building energy performance and analysis, and (3) BIM and energy assessment. Literature cited in this paper shows that linking an energy analysis tool with a BIM model has helped project design teams to predict and create optimized energy consumption by conducting building energy performance analysis utilizing key performance indicators on average thermal transmitters, resulting heat demand, lighting power, solar heat gains, and ventilation heat losses. An in-depth analysis was conducted on a completed BIM integrated construction project utilizing the Arboleda Project in the Dominican Republic to validate the aforementioned findings. Results show that the BIM-based energy analysis helped the design team attain the world׳s first positive energy building. This study concludes that linking an energy analysis tool with a BIM model helps to expedite the energy analysis process, provide more detailed and accurate results, and deliver energy-efficient buildings. This study further recommends that the adoption of level 2 BIM and BIM integration in energy optimization analysis must be demanded by building regulatory agencies for all projects regardless of procurement method (i.e., government funded or otherwise) or size.

Conservation and modern architecture. Fortune and misfortune of the School of Mathematics at Rome University (G. Ponti, 1932–1935)
S. Salvo

Frontiers of Architectural Research (2015).

Abstract
The framework of the Italian restoration doctrine is based on the reception and transmission of the memory of the past. However, interventions in modern architecture represent a radical drift in the sense that they mostly consist of reconstructions, refurbishments, and renovations. Such work disregards the sense of value acknowledgment that is implicit in architectural conservation and neglects the importance of material conservation. The uneven fortune of the School of Mathematics at Rome׳s University Campus illustrates this situation. This predicament is similar to that of many other modern buildings that have been declared “monuments” by mouth but are actually bent to listless and insensible use, mistreated, and hardly maintained. The recent work carried out at the School of Mathematics proves that interventions on modern buildings are mostly insensitive to their true significance and are often carried out in extreme urgency for mere practical reasons, if not for political opportunities. Modern buildings can be true architectural monuments that express great esthetic potentials and retain notable historical weight in the history of architecture, therefore, they should be regarded as highly representative of our recent past and maintained as such.

Influence of geometry on legibility: An explanatory design study of visitors at the Kuala Lumpur City Center
H. Safari, F. Moridani, S. Mahdzar

Frontiers of Architectural Research (2016). Vol. 5 pp. 499-507

Abstract
Legibility is based on landmarks and geometry. Visitors in a space learn to “read” an area by using three- and two-dimensional cues. This research aimed to determine the responses of visitors to the influence of geometry on the legibility at Kuala Lumpur City Center (KLCC). The relationship between geometry and space legibility can affect visitors׳ wayfinding. In this study, visitors, including 86 respondents and 8 individuals who participated in a focus group, were surveyed through questionnaires and interviews during daytime. Results show that legibility was moderately and positively correlated with regular geometry, but legibility was negligibly affected by existing geometry. Regression analysis, t -test, ANOVA, and scheme coding of qualitative data suggested that regular geometry used in urban spaces might strongly improve legibility. For urban designers, regular geometry associated with landmarks enhances legibility.

Community in the information age: Exploring the social potential of web-based technologies in landscape architecture and community design
D. Ruggeri, D. Young

Frontiers of Architectural Research (2016). Vol. 5 pp. 15-26

Abstract
Critics have pointed at new technologies as culprits in the decline of civic life, neighboring and social capital construction in Western societies. When applied to community design and planning processes, technologies can empower residents to actively engage in decision-making, foster connections across social groups, with positive consequences on life and socialization in public spaces. What kind of participation do technologies foster? And is it the kind that bridges social and ideological divides? The 2012 community design process for Hawthorne Park in Medford, Oregon illustrates many of the challenges and opportunities connected to the use of new technologies in design. In the process, technologies were instrumental in enlisting a larger-than-usual number of residents to participate in the design of the park. Blogs and online questionnaires were successful in gathering people׳s thoughts on the design choices being made, but also favored a limited, intermittent form of engagement. The results are synthesized in principles for the successful integration of web-based technologies in future community design efforts: adaptability, full participation, nuanced participation and the need for links to the physical realm.

Platform and receptacle: Musings of modernity arising from Utzon׳s own houses
X. Ruan

Frontiers of Architectural Research (2016). Vol. 5 pp. 332-340

Abstract
Utzon throughout his life time designed and built three houses for himself and his family. A study of these houses shows the slow development of a doubt, albeit understated, on his early architectural belief that was much celebrated in his public buildings, such as the Sydney Opera House. But Utzon is not unique in this instance. Some other modern architects too had experienced a similar change, gradual or sudden, in their attitudes towards life and the world, hence the transformation of their architecture as a consequence. This change, on the surface and as represented in architecture, is from a building that boldly embraces outside vista to that of a more internalized receptacle. But unlike Corbusier, Utzon, instead of a complete transformation, showed an inner conflict arising from this doubt, which is between the modern urge to conquer the capacious space out there and a yearning for an interior life.

Applying the electroforming process to bio-inspired architecture: The case of Castelbuono Estate Winery
S. Rossi, M. Pellizzari

Frontiers of Architectural Research (2013). Vol. 2 pp. 435-444

Abstract
Inaugurated in June 2012, the Carapace at Castelbuono Estate Winery in Italy is a highly interesting example of biomorphic architecture. The structure, an artistic creation of world-renowned sculptor Arnaldo Pomodoro, is reminiscent of a tortoise shell that conveys a sense of protection: the Carapace structure guards wine barriques in the same way that the tortoise carapace protects the animal. Zoomorphic aspects are further exhibited by symbols on the roof, which remind observers of cuttlefish bone, a recurring element in the artistic production of Maestro Pomodoro. The roof was constructed by assembly of single copper plates with a rough surface in accordance with the design of the artist. Therefore, determining the appropriate production process was crucial. Electroforming was selected as the method to achieve a challenging architectural goal.

A literature review on the improvement strategies of passive design for the roofing system of the modern house in a hot and humid climate region
Q. Roslan, S. Ibrahim, R. Affandi, M. Nawi, A. Baharun

Frontiers of Architectural Research (2016). Vol. 5 pp. 126-133

Abstract
Increase of indoor temperature compared with outdoor temperature is a major concern in modern house design. Occupants suffer from this uncomfortable condition because of overheating indoor temperature. Poor passive design causes heat to be trapped, which influences the rise in indoor temperature. The upper part, which covers the area of the roof, is the most critical part of the house that is exposed to heat caused by high solar radiation and high emissivity levels. During daytime, the roof accumulates heat, which increases the indoor temperature and affects the comfort level of the occupants. To maintain the indoor temperature within the comfort level, most house designs usually depend on mechanical means by using fans or air conditioning systems. The dependence on a mechanical ventilation system could lead to additional costs for its installation, operation, and maintenance. Thus, this study concentrates on reviews on passive design and suggests recommendations for future developments. New proposals or strategies are proposed to improve the current passive design through ventilated and cool roof systems. It is possible to achieve the comfort level inside a house throughout the day by reducing the transmitted heat into the indoor environment and eliminating the internal hot air. These recommendations could become attractive strategies in providing a comfortable indoor temperature to the occupants as well as in minimizing energy consumption.

A parametric investigation of the acoustical performance of contemporary mosques
M. Ismail

Frontiers of Architectural Research (2013). Vol. 2 pp. 30-41

Abstract
Acoustics is an important factor in mosque prayer halls that had not been given extensive concern during the architectural design stages. Eventually, the importance of speech intelligibility became more important, given the integration of other activities into the prayer halls, such as the holy Quran recitation, speeches, and lectures. Early attempts have been made to control the propagation of sound and to maintain good acoustic quality within the prayer spaces. Architects during the conceptual design stage had barely paid attention to the design issues that affect the acoustic environment inside the prayer zones, which is either due to lack of time during the project development or, in most cases, a lack of simple design guidelines to overcome any drastic acoustical defects arising from the incorrect design, shape, or material selection. The basic guidelines for designers to select the appropriate shape, geometry, size, and finishing materials are an essential design tool. This work examines the three common design topologies of mosques, which differ in size, shape, and finishing materials. In this study, a geometric and material parametric analysis was conducted based on the shape, surface area, volume, and finishing materials of each of the three designs. For the geometric acoustics, a computer model employing the ray tracing theory was employed to investigate the three configurations. Different acoustic treatments were tested relative to the geometric disposition of each design. Finally, basic recommendations and design guidelines were presented.

Quiet environment: Acoustics of vertical green wall systems of the Islamic urban form
M. Ismail

Frontiers of Architectural Research (2013). Vol. 2 pp. 162-177

Abstract
The development of sustainability has made the application of green concepts to cityscapes and urban design mandatory and has popularized the installation of vegetation on external street walls. Introducing greenery on external building elements is beneficial to the environment, reducing the heat impact experienced in “urban heat islands” and enhancing an areas visual effect. The popularity of such green systems has necessitated the assessment of their acoustic characteristics and their impact on long-distance noise propagation. These effects become important in hot climates, where the topology of the dense urban texture gives building walls larger areas than exposed streets, thereby amplifying the effects of the formers acoustic characteristics on noise levels. Considering the resultant sound level at a particular location between buildings as the contribution of several remote sources, a simplified computer model based on energy exchange is developed in this study. Owing to the complexity of the urban landscape, buildings are assumed to be an array of rectangular blocks. The computer model is used to investigate the effects of the installation of street vertical vegetation on long-distance noise propagation, as well as those of the geometric parameters of the dense Islamic urban texture on the resultant noise levels.

Sound preferences of the dense urban environment: Soundscape of Cairo
M. Ismail

Frontiers of Architectural Research (2014). Vol. 3 pp. 55-68

Abstract
A questionnaire study was conducted to investigate the soundscape preferences of the sonic environment in Cairo. Participants, who were Cairo residents, were questioned about their appraisal of familiar urban soundscapes in a close- and open-ended format questionnaire. Psycholinguistic data analysis of verbal descriptions expressed by respondents was conducted to identify the relevance of semantic categories of environmental sounds and quantitative soundscape aspects for the urban sonic environment of Cairo. Results confirmed a direct relevance of the linguistic semantic auditory judgment and of the outputs of the quantitative close-ended questions. Cairenes were also found to express their sonic environment linguistically based on physical properties rather than semantic features and values. Analyzing the relative annoyance increase (RAI ) of the close-ended part, overall positive RAI values for all sound categories reveal how sensitive to noise Cairo residents are. Results further showed that at an RAI value of approximately 27%, sound category perception transforms from positive to negative.

Modernity in tradition: Reflections on building design and technology in the Asian vernacular
M. Rashid, D. Ara

Frontiers of Architectural Research (2015). Vol. 4 pp. 46-55

Abstract
Vernacular buildings across the globe provide instructive examples of sustainable solutions to building problems. Yet, these solutions are assumed to be inapplicable to modern buildings. Despite some views to the contrary, there continues to be a tendency to consider innovative building technology as the hallmark of modern architecture because tradition is commonly viewed as the antonym of modernity. The problem is addressed by practical exercises and fieldwork studies in the application of vernacular traditions to current problems. This study investigates some aspects of mainstream modernist design solutions and concepts inherent in the vernacular of Asia, particularly that of the Chittagong Hill Tracts (CHT). This work hinges on such ideas and practices as ecological design, modular and incremental design, standardization, and flexible and temporal concepts in the design of spaces. The blurred edges between the traditional and modern technical aspects of building design, as addressed by both vernacular builders and modern architects, are explored.

Critical analysis of key determinants and barriers to digital innovation adoption among architectural organizations
R. Ramilo, M. Embi

Frontiers of Architectural Research (2014). Vol. 3 pp. 431-451

Abstract
The development and use of design technology for architecture in the modern world have led to the emergence of various design methodologies. Current design research has focused on a computationally mediated design process. This method is essentially concerned with finding forms and building performance simulation, i.e., structural, environmental, constructional, and cost performance, by integrating physics and algorithms. From the emergence of this process, design practices have been increasingly aided by and dependent on the technology, which has resulted in a major paradigm shift. Advancement of the new technology has the potential to improve design and productivity dramatically. However, related literature shows that substantial technical and organizational barriers exist. These barriers inhibit the effective adoption of these technologies. The effect of these obstacles on architectural practice varies depending on the size of an architectural organization. To further understand the problem, we conducted an in-depth study on several small, medium, and large architectural organizations. This study involves in-depth evaluation of technological, financial, organizational, governmental, psychological, and process barriers encountered in the adoption of digital innovation. Results reveal relevant attributes and patterns of variables, which can be used to establish a framework for digital innovation adoption. Valuable findings of this study reveal that smaller architectural organizations present more barriers to digital innovation compared with their larger counterparts. This study is important because it contributes to the research on digital innovation in architecture and addresses the barriers faced by different sizes of architectural organizations.

Quantifying the relationship between visitor satisfaction and perceived accessibility to pedestrian spaces on festival days
A. Pratiwi, S. Zhao, X. Mi

Frontiers of Architectural Research (2015). Vol. 4 pp. 285-295

Abstract
Many cities organize cultural festivals to promote their distinctiveness, boost the local economy, and enhance quality of life. However, urban spaces are packed with visitors on festival days, thus affecting accessibility to pedestrian spaces. This research examined visitor satisfaction with accessibility to pedestrian spaces during special events such as festivals. We particularly focused on the Hakata Dontaku festival, which is celebrated in Fukuoka, Japan. We studied three main elements that affect pedestrian satisfaction and perceived accessibility through walking, namely, safety, mobility, and amenities. We first analyzed previous studies and employed analytical hierarchy process to setup indicators for satisfaction measurement. Second, we determined visitor satisfaction through a survey questionnaire, which was conducted during the Hakata Dontaku festival. Third, we assessed the normality of the data set that was obtained from the questionnaire. Finally, we applied structural equation modeling. Results showed that the proposed model was a good fit, as indicated by the goodness of fit test, and the majority of indicators loaded significant values that supported their constructs. Satisfaction with amenities was found to be the most statistically significant variable that influences visitors׳ perceived accessibility during the Hakata Dontaku festival.

Case study on father–child communication in Chinese urban apartment houses through active RFID technology
X. Qu, D. Matsushita, T. Yoshida, M. Han

Frontiers of Architectural Research (2012). Vol. 1 pp. 58-68

Abstract
This paper used Active Radio Frequency Identification (Active RFID) technology to identify in which rooms fathers and their child tend to stay together and talk, and in which rooms they stay separately in seven one-child families living in Chinese urban apartment houses. The father was found to stay together with the child 0.5%–25% of the time when both father and child stayed at home. The use of the living room as the place in which the child stays with the father and talks was found to be highest (five out of seven families), followed by the dining room and the childs room. In over half of the cases when the child stays with the father in the living room or dining room and either of them talk, the child spoke over 1.6 times more than the father. However, in the childs room, the child always spoke less than the father, and the duration of the childs speech was less than 70% of that of the father. Findings showed that the instances in which child and father stay in different rooms fell into two groups. First, five of the seven subject fathers tended to stay in the living room, whereas the children stayed either in their room or in their parents' room to use the PC. Second, two fathers stayed in the studio or dining room to work, while their children stayed in the living room or their own rooms. For both groups, the duration of these periods of stay covered 30.0%–81.4% of the time during which both the father and child stayed at home.

Role of bazaars as a unifying factor in traditional cities of Iran: The Isfahan bazaar
M. Pourjafar, M. Amini, E. Varzaneh, M. Mahdavinejad

Frontiers of Architectural Research (2014). Vol. 3 pp. 10-19

Abstract
A city is a vital organism that lives and grows like other organisms. Therefore, implementing development plans that would provide a sense of unity and integration in relation to the city as a whole is necessary. Traditional Iranian architecture is full of samples evolved during the course of Iranian history that can serve as architectural paragons of the city. In Irans traditional cities, a sense of unity exists in various urban areas. The traditional city of Isfahan is one of the most valuable samples and was selected as the case study in this research. Accordingly, the most important questions of this research are as follows: (1) What is the role of bazaars in creating a sense of unity in the traditional cities of Iran? (2) How do bazaars play out their role in the integration of these cities? This research focuses on the concept of a “traditional city” to determine the role of bazaars in such cities. The results show that bazaars are crucial in giving a sense of integrity to the concept of a traditional Iranian city. Bazaars provide cohesion among the different parts of cities, such as residential areas, as well as socio-political and trade centers. This condition means that traditional bazaars play two important roles in traditional cities: (1) they interconnect the different parts of the citys physical structure, and (2) the crucial role of bazaars in a citys social and cultural structure brings about unity among the citizens in the city. Bazaars as a unifying element connect the main urban functions and guarantee the citys economic and social life.

Frontiers of Architectural Research (2013). Vol. 2 pp. 267-277

Abstract
Several researches show the environmental and microclimatic benefits of the integration of vegetation in architecture, however the potentialities of vertical and horizontal greening systems to retrofit buildings are still not much investigated. The retrofitting project of the Barsanti Institute of Camogli (Genoa, Italy) is presented, a building dated back to the sixties with serious architectural and efficiency problems, located in a considerable landscape area. The development and application of a design tool (process tree), for horizontal and vertical greened surfaces, allows to evaluate the potentialities of vegetation to retrofit and to relate the encountered efficiency problems and the climate characteristics with the choice of plant species, system, and technology more suitable for the specific situation (of which environmental and economic impact are also evaluated) and to define a design approach for the systematic consideration of the many parameters involved.

Restoration of the façade of the Pirelli skyscraper in Milan and the repair of damage to reinforced concrete structures caused by a plane crash: An example of critic conservation
A. Campanelli

Frontiers of Architectural Research (2014). Vol. 3 pp. 213-223

Abstract
The restoration of the former Pirelli Tower in Milan, which dates back to the early 1950s, is an example of various issues in approaching the “conservation of the new”. This project was completed with the broad use of industrial products that evoked different kinds of reflections, if only within the same planning methodology, common to all interventions of architectural restoration. This restoration constitutes an exemplary episode where only a careful and critical evaluation facilitated the understanding of which elements are important in conservation and which can be substituted or updated. This approach uses case-to-case evaluations. The conservation of “new” architecture is similar to other restoration problems, except for the closeness in time to the original works and, sometimes, with its creator. The main intervention concerns the recovery of the structure with over 10, 000 m2 of continuous aluminum and glass façade in a skyscraper designed by Italian master Gio Ponti and the repair of the damage to the reinforced concrete (RC) structures (designed by another Italian master, Pier Luigi Nervi) caused by a plane crash. The straightening and repair of the RC using entirely innovative methods and the conservation of the structures of the whole façade also translates into financial savings. Approximately 20% of the savings is derived from the complete substitution of the curtain wall. This idea of authenticity results in a method of restoration in which all single parts may not always be replaced for every functional upgrade. This scenario is important news, especially for modern architecture that usually prefers the value of what appears to be new, showing parts that are always perfect since the time they were built. People also consider the conservation of items that were considered as merely industrial products a few years ago.

The extension of Rome׳s Capitoline Museums and the design of a new Hall on the site of the ancient ‘Giardino Romano’
R. Panella, M. Tugnoli

Frontiers of Architectural Research (2015). Vol. 4 pp. 171-185

Abstract
The new Hall of Marcus Aurelius in the Capitoline Museums, located within the ancient site of Giardino Romano, displays the original statue of the Roman emperor of the 2nd century AD. The idea of extending the Capitoline Museums by including this site came about in the framework of its general redevelopment.1 The new Hall is the result of a long and complicated process (1988–2005) considering the exceptional importance of the site and the many changes brought to the museum programme during the said period (Figure 1, Figure 2 ).In fact, the new Hall was originally supposed to display the marbles of the Temple of Apollo Sosianus, the foundation wall of the Temple of Capitoline Jupiter, embedded within the structures of the Palazzo Caffarelli, opposite the Giardino Romano. However, in 1997, the plan for the Capitoline Museum changed radically as the statue of Marcus Aurelius, which had been restored following the blast of a bomb attack in 1979, was determined to be the focus of the Hall. The project finally consisted of a steel and glass structure on an elliptic plan andshaped around the foundations of the Temple, with the statue at its center.

Privacy, modesty, hospitality, and the design of Muslim homes: A literature review
Z. Othman, R. Aird, L. Buys

Frontiers of Architectural Research (2015). Vol. 4 pp. 12-23

Abstract
Traditional Islamic teachings and traditions involve guidelines that have direct applications in the domestic sphere. The principles of privacy, modesty, and hospitality are central to these guidelines, each principle has a significant effect on the design of Muslim homes, as well as on the organization of space and domestic behaviors within each home. This paper reviews literature on the privacy, modesty, and hospitality within Muslim homes. Nineteen publications from 1986 to 2013 were selected and analyzed for content related to the meaning of privacy, modesty, and hospitality in Islam and the design of Muslim homes. Despite the commonly shared guidelines for observing privacy, modesty, and hospitality within each home, Muslims living in different countries are influenced by cultural factors that operate within their country of residence. These factors help to shape the architectural styles and use of space within Muslim homes in different ways. Awareness of the multifactorial nature of the influences on the Muslim perception of home and the use of space is necessary for architects, building designers, engineers, and builders to be properly equipped to meet the needs of clients.

Towards more culturally inclusive domestic toilet facilities in Australia
Z. Othman, L. Buys

Frontiers of Architectural Research (2016). Vol. 5 pp. 383-391

Abstract
The topics on toilets, defecation and perianal cleansing may be perceived as taboo subjects in daily discussions but are markedly important from health and hygienical perspectives. In multicultural countries like Australia, no research attention has been given to domestic toilet hygienical requirements from the perspective of the society׳s cultural traditions or religious teachings. The Western sitting lavatories with toilet paper facilities are the most common toilet systems available in Australian homes, which may be contradictory to persons coming from non-Western backgrounds. Squat latrines used widely in many Asian countries are acknowledged to be more conducive for maintaining a healthy bowel system, but are unattractive to Westerners and also unsuitable for those with physical disabilities. Similarly, water is regarded as the most hygienical option for perianal cleansing in many cultures but is rarely used in Western cultures. This paper investigates the experiences of seven Muslim families living in Brisbane with respect to whether or not the Australian toilet systems in their homes meet their personal and familial requirements. This paper further explores whether modifications were made to their domestic toilets to meet these essential needs. Some design recommendations are presented, which are based on the extant literature on this topic as well as the findings from this study. These design options provide an opportunity for future research focussed on a universal toilet design solution that is adaptable and able to meet the needs of all users, especially for those countries with a multicultural population.

Simply complex, toward a new kind of building
K. Oosterhuis

Frontiers of Architectural Research (2012). Vol. 1 pp. 411-420

Abstract
The world around us is evolving. We are living inside evolution. As a practicing architect I find nothing more natural than to look around me and implement relevant changes into my own profession. Taking this seriously means implementing new digital technologies in the very fabric of design methods, from the first conceptual thought and from the first accurately described design proposal. Mass production is soon to be overhauled by the principles of customization, in the form of both industrial mass customization and in the form of distributed small scale household fabrication. Customization, which is the modern made to measure, will change architecture from its very foundations. A completely new esthetic will be the natural outcome of the digital parametric design process that connects the file to factory CNC production methods— a new kind of beauty for a new kind of building. Complexity based on simple rules characterizes the dramatic paradigm shift from mass production to customization. The new kind of building is complex yet systemic in its design method. The new kind of building dramatically enhances the potential of todays architectural expression while keeping strict control on its data, including costs. Truly nonstandard architecture is cost-effective and simply complex.

Relationship between tile exfoliation and moisture content
S. Onmura, S. Hokoi, D. Ogura

Frontiers of Architectural Research (2013). Vol. 2 pp. 301-309

Abstract
In Japan, tile exfoliation from external walls is a serious problem that must be prevented. In our previous study, a tiled concrete sample was dried at a temperature of 105 °C for pre-conditioning. Then, tile exfoliation occurred. Since this seemed to indicate a relationship between tile exfoliation and moisture content, it was further pursued in this study. First, drying experiments on concrete samples just after tiling were carried out under different ambient air temperatures. The following results were obtained. • Tile exfoliation occurs even at the lower drying temperatures. • Tile exfoliation starts at corner tiles (seen in all experiments). • When the average moisture content of the tiled concrete sample becomes lower than a certain value, tile exfoliation occurs. Next, the experiments were analyzed using a three-dimensional model of simultaneous heat and moisture transport. The calculated moisture content agreed well with the measured results. By comparing the measurement and simulation results, it is considered that the tiles are exfoliated when the moisture content of the mortar on the back side of the tile becomes lower than a certain value. Therefore, the moisture content can serve as an index for evaluating the occurrence of the tile exfoliation.

Abstract
This paper explored through a literature review, the domains of research in Architecture and the nature of doctoral research, with a view to contributing to the evolving research agenda in the Nigerian context. The research method involved a descriptive and thematic analysis of the titles and abstracts of completed doctoral theses in Architecture in Nigeria, in the last 26 years (1990–2015), complemented by semi-structured interviews with six key informants. The study revealed an emphasis on Housing-related topics (34%) relative to other research modules, such as׳ History and Theory׳ (20%) and ׳Design and Production׳ (18%). It also reflected the limited coverage and scope of current research, relative to the global terrain, as evidenced in the article titles and contents of 45 Architecture-related Journals. The results of the interviews indicated the strong influence of supervisors׳ areas of interest in the choices of thesis titles. It highlighted reasons for the perceived focus on Housing, which reflect its unique place and multi-disciplinary nature. It concluded that extending the boundaries of architectural research at the doctoral level could be beneficial to the discipline and profession in Nigeria in order to align with global trends, while keeping cognizance of the local contexts.

Average TVOC, CO2, O3, CO, and particle concentrations measured in the classrooms were 815 µg/m3, 1605 ppm, 0.05 ppm, 1.16 ppm, and 1730 µg/m3, respectively. Whereas, local authority known as Dubai Municipality recommended 300 µg/m3, 800 ppm, 0.06 ppm, 9 ppm, and 150–300 µg/m3 for TVOC, CO2, O3, CO, and particle, respectively. Dubai Municipality recommended temperature and relative humidity (RH) levels of 22.5 °C to 25.5 °C and 30%–60%, respectively. Average temperature and RH levels measured in the classrooms were 24.5 °C and 40.4%, respectively. Average sound level in the classrooms was 24 dB greater than recommended sound level limit of 35 dB. Six (6) classrooms had average lux levels in the range of 400–800 lux. Two (2) classrooms had average lux levels in the range of 100–200 lux. The remaining classrooms had lux levels around the recommended 300 lux. High occupancy density was observed in majority of the studied classrooms. Observations during walkthrough investigations could be used to explain measured IEQ data. Poor IEQ conditions in the studied classrooms highlight the need for further research investigation to understand how poor classrooms׳ IEQ condition could influence students׳ health, comfort, attendance rate, and academic performance.

Performance evaluation of residential buildings in public housing estates in Ogun State, Nigeria: Users' satisfaction perspective
E. Ibem, A. Opoko, A. Adeboye, D. Amole

Frontiers of Architectural Research (2013). Vol. 2 pp. 178-190

Abstract
This study assessed the performance of residential buildings in public housing estates in urban areas of Ogun State Southwest Nigeria. It was based on the notion that users' satisfaction with dwelling units is a measure of the performance of residential buildings in meeting their needs and expectations. A cross sectional survey of 452 household heads in nine public housing estates was conducted in the study area. Data were obtained using structured questionnaire and observation schedule, and were subjected to descriptive statistics and factor analysis. A mean satisfaction score of 3.21 was observed, indicating that the respondents were generally satisfied with the performance of the different components of the buildings. Satisfaction levels were generally higher with privacy and sizes of living and sleeping areas than the availability of water and electricity in the buildings. The type, location and aesthetic appearance as well as size of main activity areas were the most predominant factors that determined satisfaction and indeed the performance of the buildings in meeting users' needs and expectations. The paper highlights critical areas where attention is needed in order to improve the performance of residential buildings and users' satisfaction with public housing projects in Nigeria.

Entry qualifications and academic performance of architecture students in Nigerian Polytechnics: Are the admission requirements still relevant?
P. Adewale, O. Adhuze

Frontiers of Architectural Research (2014).

Abstract
The competence of fresh graduates of architecture has been continuously criticized by the industry for inadequate knowledge. This is often blamed on the poor standard of education evidenced by poor performances in professional and degree/diploma examinations conducted by various schools of architecture in the country. Although, factors responsible for the scenario are well documented in the literature, most of these works are based on testimonial and circumstantial evidences relating to management of architectural education only. The aim of this paper is to investigate the relationship between entry qualifications and the performance of architecture students in Nigerian Polytechnics with a view to determining the relevance of current admission policy to architectural education in Nigeria. Data were obtained from official records in the Department of Architecture in four randomly selected polytechnics in the southwestern part of Nigeria. Pearson Product Moment Correlation (r ) was used to test the hypotheses. Findings reveal weak relationship between the two variables (physics and mathematics). This is contrary to the expectations of most scholars and policy makers who opine that students' proficiency in these subjects would enhance their performance at higher levels. The paper traces the contradiction to the poor handling of public examinations and misconception of architecture as being pure science. It holds that if these requirements are still relied upon for the admission of students into schools of architecture, wrong candidates would continue to gain entry into the profession. The paper concludes by recommending certain measures that are capable of reversing the trend.

Assembling the unexpected inspiration–from linking to jigsaw
C. Lo, T. Chang, I. Lai

Frontiers of Architectural Research (2014). Vol. 3 pp. 358-367

Abstract
Linking pieces of design information for inspiration are an important part of the early phase of the design process. One key linking operation is assembling, wherein designers create new ideas by assembling partial or whole pieces of ideas together. How designers assemble the ideas reflect their design process. Hence, by developing a computational tool for assembling ideas, the underlying rules of design decision-making might be revealed. In this research, we employed a computational design method consisting of methodological mapping (jigsaw) and consequential analysis (Design Jigsaw system prototype) to create associations between varied types of information at different levels in the design information hierarchy. We then propose a system prototype called Design Jigsaw, based on the analysis of five representation schemes with network-like structures and sound delegation mechanisms. We also developed and explored the representation, components, and the control mechanisms involved in these components. The algorithm of the two main control strategies, grouping and matching/combining, is described in detail along with the procedural description of a jigsaw solving session. Furthermore, we conducted a design experiment to reify the process of the Design Jigsaw system prototype.

Does the smartest designer design better? Effect of intelligence quotient on students’ design skills in architectural design studio
S. Nazidizaji, A. Tomé, F. Regateiro

Frontiers of Architectural Research (2015). Vol. 4 pp. 318-329

Abstract
Understanding the cognitive processes of the human mind is necessary to further learn about design thinking processes. Cognitive studies are also significant in the research about design studio. The aim of this study is to examine the effect of designers intelligence quotient (IQ) on their designs. The statistical population in this study consisted of all Deylaman Institute of Higher Education architecture graduate students enrolled in 2011. Sixty of these students were selected via simple random sampling based on the finite population sample size calculation formula. The students’ IQ was measured using Raven’s Progressive Matrices. The students’ scores in Architecture Design Studio (ADS) courses from first grade (ADS-1) to fifth grade (ADS-5) and the mean scores of the design courses were used in determining the students’ design ability. Inferential statistics, as well as correlation analysis and mean comparison test for independent samples with SPSS, were also employed to analyze the research data. Results indicated that the students’ IQ, ADS-1 to ADS-4 scores, and the mean scores of the students’ design courses were not significantly correlated. By contrast, the students’ IQ and ADS-5 scores were significantly correlated. As the complexity of the design problem and designers’ experience increased, the effect of IQ on design seemingly intensified.

Search for design intelligence: A field study on the role of emotional intelligence in architectural design studios
S. Nazidizaji, A. Tomé, F. Regateiro

Frontiers of Architectural Research (2014). Vol. 3 pp. 413-423

Abstract
The design studio is the core of the architecture curriculum. Interpersonal interactions have a key role during the processes of design and critique. The influence of emotional intelligence (EQ) on interpersonal communication skills has been widely proven. This study examines the correlation between EQ and architectural design competence. To achieve this, 78 architecture students were selected via a simple random sampling method and tested using an EQ test questionnaire developed by Bradbury and Greaves (2006) . The scores of five architectural design studio courses (ADS-1, ADS-2, ADS-3, ADS-4, and ADS-5) were used as indicators of the progress in design of the students. Descriptive and inferential statistics methods were both employed to analyze the research data. The methods included correlation analysis, mean comparison t -test for independent samples, and single sample t -test. Findings showed no significant relationship between EQ and any of the indicators.

Palazzo Valentini: Archaeological discoveries and redevelopment projects
L. Napoli, P. Baldassarri

Frontiers of Architectural Research (2015). Vol. 4 pp. 91-99

Abstract
Palazzo Valentini, a historical site of Rome׳s Provincial Administration, is located at the heart of the city. The building was purchased in 1827 by Vincenzo Valentini, a banker and consul general of the Prussian Crown. In 1939, with the outbreak of World War II, a fully self-contained, air-raid shelter was built under the courtyard, with an exit tunnel heading onto the Trajan׳s Forum. Archaeological investigations started in 2005 in view of a simple rehabilitation work of the underground level. As work progressed, the sample-plots brought to light new archaeological findings: relics of a huge temple and what remained of two residential houses with thermal baths. We therefore designed an exhibition space with glass surfaces to allow visitors to appreciate the findings while following a path through historical ages: from the 16th-century courtyard to the underground Roman domus (the sumptuous houses of senators and dignitaries of the Roman Empire), with private baths, to the remains of a Roman temple, and all the way to the Trajan׳s Column pedestal by way of the air-raid shelter. Virtual reconstructions, graphic effects, and movies are the means used to revive the hypothetical original appearance of the environments and the daily life of that epoch in order to help us build a prototype of an on-site museum of the third millennium.

Impact of urban upgrading on perceptions of safety in informal settlements: Case study of Bouakal, Batna
F. Naceur

Frontiers of Architectural Research (2013). Vol. 2 pp. 400-408

Abstract
This paper explores how modifications of urban space in informal settlements influence residents′ quality of life and perceptions of safety. This is a case study of Bouakal, the oldest informal district in Batna, a middle city in Algeria. This paper examines the effects of urban improvement practices in Bouakal by exploring two questions: In what ways did interventions in this informal settlement affect the quality of life for the residents? How do these effects correlate with changes in the perception of safety in this area? The survey involved 141 residents from Bouakal, and local residents were selected to collect the levels of perceived safety. This paper concludes that urban upgrading has improved the quality of life and has a positive effect on the perception of safety in the settlement.

Post-occupancy evaluation of a restored industrial building: A contemporary art and design gallery in Mexico
J. Mundo-Hernández, M. Valerdi-Nochebuena, J. Sosa-Oliver

Frontiers of Architectural Research (2015). Vol. 4 pp. 330-340

Abstract
This paper presents the results obtained from a post-occupancy evaluation (POE) study conducted in an old fabric building called “La Violeta ”. This structure has been recently converted into a contemporary art gallery. La Violeta is located in Puebla City, Mexico. The building dates from the beginning of the 19th century, it was built and used as a textile factory until the first decades of the 20th century. This POE study aims to assess the new use of the building from the users׳ point of view. Methodology involves historical research of the building, analysis of the conversion strategy, walkthrough investigation, and a user survey. Questions regarding the re-utilization strategy used in the building and its current use are included in the survey, such as “How do people perceive the space regarding its functionality, accessibility, and comfort?” Although the re-utilization process destroyed several historic elements, the re-use of old industrial spaces that otherwise would be obsolete and disused seems pertinent. Developing small renovation projects as part of an integral and wider project seems feasible. Users perceive the building as comfortable but not properly advertised as an art gallery, and its location is difficult to find.

Performance-driven design with the support of digital tools: Applying discrete event simulation and space syntax on the design of the emergency department
D. Morgareidge, H. CAI, J. JIA

Frontiers of Architectural Research (2014). Vol. 3 pp. 250-264

Abstract
Planning the design of the emergency department (ED) is a complex process. Hospital leaders and architects must consider many complex and interdependent factors, including evolving market demands, patient volume, care models, operational processes, staffing, and medical equipment. The application of digital tools, such as discrete event simulation (DES) and space syntax analysis (SSA), allows hospital administrators and designers to quantitatively and objectively optimize their facilities. This paper presents a case study that utilized both DES and SSA to optimize the care process and to design the space in an ED environment. DES was applied in three phases: master planning, process improvement in the existing ED, and designing the new ED. SSA was used to compare the new design with the existing layout to evaluate the effectiveness of the new design in supporting visual surveillance and care coordination. This case study demonstrates that DES and SSA are effective tools for facilitating decision-making related to design, reducing capital and operational costs, and improving organizational performance. DES focuses on operational processes and care flow. SSA complements DES with its strength in linking space to human behavior. Combining both tools can lead to high-performance ED design and can extend to broad applications in health care.

P. Moonen, T. Defraeye, V. Dorer, B. Blocken, J. Carmeliet

Frontiers of Architectural Research (2012). Vol. 1 pp. 197-228

Abstract
The global trend towards urbanisation explains the growing interest in the study of the modification of the urban climate due to the heat island effect and global warming, and its impact on energy use of buildings. Also urban comfort, health and durability, referring respectively to pedestrian wind/thermal comfort, pollutant dispersion and wind-driven rain are of interest. Urban Physics is a well-established discipline, incorporating relevant branches of physics, environmental chemistry, aerodynamics, meteorology and statistics. Therefore, Urban Physics is well positioned to provide key-contributions to the current urban problems and challenges. The present paper addresses the role of Urban Physics in the study of wind comfort, thermal comfort, energy demand, pollutant dispersion and wind-driven rain. Furthermore, the three major research methods applied in Urban Physics, namely field experiments, wind tunnel experiments and numerical simulations are discussed. Case studies illustrate the current challenges and the relevant contributions of Urban Physics.

Frontiers of Architectural Research (2016). Vol. 5 pp. 319-331

Abstract
In this paper, the city prosperity manifest is analyzed through a logical process and a framework is then proposed for designing healthy buildings in Tehran. The current status of urbanization in terms of the number of people living together and the changes in old behavior and perspectives have resulted in deficiencies to the health and hygiene of buildings apart from their surrounding environment. Consequently, these problems have affected people׳s well-being. This study mainly aims to determine policies and strategies for the architectural design of healthy buildings according to health and safety conditions that influence the quality of internal spaces and external environment of cities. The study is conducted based on logical reasoning and uses focus group and in-depth interviews to assess the final result. The result is a framework that suggests a number of policies that can promote the mental and physical health as well as hygiene of residents through healthy buildings.

Optimizing energy efficiency and occupant comfort with climate specific design of the building
C. Mitterer, H. Künzel, S. Herkel, A. Holm

Frontiers of Architectural Research (2012). Vol. 1 pp. 229-235

Abstract
Designing energy efficient and comfortable buildings requires harmonizing the complex interactions of architecture, construction and building service engineering. The building envelope has a particular importance, since it integrates many functions and has direct influence on indoor climate. Focusing on satisfaction of the user means that the indoor climate is a key for a holistic design approach. Only a satisfied user will not intervene with the designed energy concept or the indoor climate control, dissatisfaction results in multiple system interventions which may cause waste of energy and sometimes even damage to building envelope components. Satisfaction with the indoor environment also increases working productivity or enables effective recreation of residents. The paper deals with international research activities in the field of climate specific building design. Various comfort and energy monitoring surveys of office buildings as well as residential buildings provide substantial information about the occupants' behavior and their needs during specific situations under different outdoor climates. This information allows summarizing basic climate dependent design principles which architects should keep in mind during the early stages of the design process. It also helps to develop strategies aiming at reducing building energy demand and at the same time consider comfort aspects. The second part of this paper demonstrates application of the climate dependent design principles in a housing project in Dubai.
