J. He, Y. Xu

Advances in Climate Change Research (2011). Vol. 2(25) pp. 211-217

Abstract
Based on the annual production data collected by the Statistic Center of the Ministry of Railways of the People’s Republic of China, we calculated the energy saving and direct emission reductions of CO2, soot, SO2, CO, NOx and Cn Hm of electrified railways, and analyzed their dynamic characteristics during the period of 1975–2007. The results show that during this period, the annual mean values of energy saving is 1.23×106 tce, and direct emission reduction of CO2, soot, SO2, CO, NOx and Cn Hm are 4.267×106 t, 20.5×103 t, 3.0×103 t, 9.6×103 t, 67.9×103 t, and 6.9×103 t per year, respectively. The annual average increasing rates of energy saving is 139×103 tce, and direct emission reduction of CO2, soot, SO2, CO, NOx and Cn Hm are 483×103 t, 2.3×103 t, 0.34×103 t, 1.1×103 t, 7.7×103 t and 0.78×103 t per year, respectively. The electrified railways have played an important role in decreasing the energy consumption and air pollutant emissions of China’s railway system. The results of this study could provide some reference knowledge for future reductions of energy consumption and waste gas emission in China’s railway transportation. He, J., and Y.

Estimation of CO2 Emissions of Locomotives in China (1975–2005)
J. He, Y. Li

Advances in Climate Change Research (2010). Vol. 1 pp. 40-45

Abstract
Based on annual statistical data collected by the Chinese Railway Statistic Center, the CO2 emissions of locomotives during 1975–2005 were calculated and the emission intensity and its dynamic characteristics were analyzed. The results show that the CO2 emissions of steam locomotives decreased while that of diesel locomotives increased with time, due to the continuous shift from steam to diesel and electric locomotives. The total CO2 emissions of steam and diesel locomotives in China decreased from 42.23 Mt in 1975 to 16.40 Mt in 2005. The emission intensity of CO2 from the two kinds of locomotives decreased at an average rate of 2.4 g (converted t km)- 1 per year. The percentage of the CO2 emissions of locomotives to the total CO2 emissions in the sector of transportation, storage and post in China also decreased persistently from 1980 to 2005. He, J., and Y.

Coping with climate change and Chinas wind energy sustainable development
D. He

Advances in Climate Change Research (2016). Vol. 7 pp. 3-9

Abstract
Greenhouse gas emissions are the main cause of todays climate change. To address this problem, the world is in an era of new round energy transformation, and the existing energy structure is being reformed. In this paper, according to the Chinese governments action plan for coping with climate change, the Chinas wind energy sustainable development goals and development route are discussed, and the countermeasures and suggestions are put forward. Wind energy is currently a kind of important renewable energy with matured technology which can be scale-up developed and put into commercial application, and in this transformation, wind energy will play a key role with other non-fossil energy sources. The development and utilization of wind energy is a systematic project, which needs to be solved from the aspects of policy, technology and management. At present, China is in the stage of transferring from “large wind power country” to “strong wind power country”, opportunities and challenges coexist, and the advantages of Chinas socialist system could be fully used, which can concentrate power to do big things and make contribution in the process of realizing global energy transformation.

Global low-carbon transition and Chinas response strategies
J. He

Advances in Climate Change Research (2016). Vol. 7 pp. 204-212

Abstract
The Paris Agreement establishes a new mechanism for post-2020 global climate governance, and sets long-term goals for global response to climate change, which will accelerate worldwide low-carbon transformation of economic development pattern, promote the revolutionary reform of energy system, boost a fundamental change in the mode of social production and consumption, and further the civilization of human society from industrial civilization to eco-civilization. The urgency of global low-carbon transition will reshape the competition situation of worlds economy, trade and technology. Taking the construction of eco-civilization as a guide, China explores green and low-carbon development paths, establishes ambitious intended nationally determined contribution (INDC) targets and action plans, advances energy production and consumption revolution, and speeds up the transformation of economic development pattern. These strategies and actions not only confirm to the trend of the world low-carbon transition, but also meet the intrinsic requirements for easing the domestic resources and environment constraints and realizing sustainable development. They are multi-win-win strategies for promotion of economic development and environmental protection and mitigation of carbon emissions. China should take the global long-term emission reduction targets as a guide, and formulate medium and long-term low-carbon development strategy, build the core competitiveness of low-carbon advanced technology and development pattern, and take an in-depth part in global governance so as to reflect the responsibility of China as a great power in constructing a community of common destiny for all mankind and addressing global ecological crisis.

An analysis of Chinas CO2 emission peaking target and pathways
J. He

Advances in Climate Change Research (2014). Vol. 5 pp. 155-161

Abstract
China has set the goal for its CO2 emissions to peak around 2030, which is not only a strategic decision coordinating domestic sustainable development and global climate change mitigation but also an overarching target and a key point of action for Chinas resource conservation, environmental protection, shift in economic development patterns, and CO2 emission reduction to avoid climate change. The development stage where China maps out the CO2 emission peak target is earlier than that of the developed countries. It is a necessity that the non-fossil energy supplies be able to meet all the increased energy demand for achieving CO2 emission peaking. Given that Chinas potential GDP annual increasing rate will be more than 4%, and Chinas total energy demand will continue to increase by approximately 1.0%–1.5% annually around 2030, new and renewable energies will need to increase by 6%–8% annually to meet the desired CO2 emission peak. The share of new and renewable energies in Chinas total primary energy supply will be approximately 20% by 2030. At that time, the energy consumption elasticity will decrease to around 0.3, and the annual decrease in the rate of CO2 intensity will also be higher than 4% to ensure the sustained growth of GDP. To achieve the CO2 emission peaking target and substantially promote the low-carbon development transformation, China needs to actively promote an energy production and consumption revolution, the innovation of advanced energy technologies, the reform of the energy regulatory system and pricing mechanism, and especially the construction of a national carbon emission cap and trade system.

Objectives and strategies for energy revolution in the context of tackling climate change
J. He

Advances in Climate Change Research (2015). Vol. 6 pp. 101-107

Abstract
Global climate change mitigation and CO2 emission reduction have promoted the revolutionary transformation in energy system. The core content of energy system revolutionary transformation is to replace the high-carbon energy system dominated by fossil energy with low-carbon energy system dominated by new and renewable energy and finally realize the near-zero emission of CO2 . The new energy system transformation has also led to a reform in global economic and social development patterns. Developing low-carbon economy becomes the fundamental strategy of sustainable development under climate risk management and the only solution to getting on the road from industrial civilization to ecological civilization. China intends to achieve the peaking of CO2 emissions around 2030 and increase the share of non-fossil fuels in primary energy consumption to around 20% by 2030. Guided by the targets, China directs its economy development to a low-carbon pattern. Therefore, new and renewable power capacity need to reach 1300 GW, and the electricity generated should be 4 times of that in 2013 with a continuous increase rate of 6%–8% around 2030. The pace of energy substitution need to be accelerated and efficient, safe, clean, and low-carbon energy supply and consumption systems should be established besides strengthened energy conservation and improved energy efficient. Therefore, reform need be deepened, favorable policy system and market mechanism for energy revolution and low-carbon development need be established, energy pricing mechanism should be reformed, and national carbon market should be formed to provide a favorable policy and market environment for low-carbon technology innovation and industry development.

Sector Mitigation Policies and Methods in China: Measurable, Reportable, and Verifiable Mechanisms
A. Gu, F. Teng, Y. Wang

Advances in Climate Change Research (2011).

Abstract
Based on a number of sector mitigation policies for domestic systems, this paper demonstrates how measurable, reportable and verifiable (MRV) mechanisms are applied at the sector level in China. At the same time, these mitigation policies and methods are diverse in terms of the MRV approach and their mitigation effects. These characters should be regulated as part of case foundation in the international construction of MRV. Gu, A., F. Teng, and Y.

Impact of ENSO events on the interannual variability of Hadley circulation extents in boreal winter
Y. Guo, J. Li

Advances in Climate Change Research (2016). Vol. 7 pp. 46-53

Abstract
The interannual variability of the boreal winter Hadley circulation extents during the period of 1979–2014 and its links to El Niño-Southern Oscillation (ENSO) were investigated by using reanalysis datasets. Results showed that the El Niño (La Niña) events can induce the shrinking (expansion) of Hadley circulation extent in the Southern Hemisphere. For the Northern Hemisphere, El Niño (La Niña) mainly leads to shrinking (expansion) of the Hadley circulation extent in the middle and lower troposphere and expansion (shrinking) of the Hadley circulation extent in the upper troposphere. The ENSO associated meridional temperature gradients have close relationship with the Hadley circulation extents in both Hemispheres. But in the Northern Hemisphere, the ENSO associated eddy momentum flux divergence plays more important role in affecting the Hadley circulation extent than the meridional temperature gradient because of the small local Rossby number. In the Southern Hemisphere, as the ENSO induced eddy momentum flux divergence is small, the meridional temperature gradient dominates the change of the Hadley circulation extent.

Climatology and interannual variability of the annual mean Hadley circulation in CMIP5 models
Y. Guo, J. Li, J. Feng

Advances in Climate Change Research (2016). Vol. 7 pp. 35-45

Abstract
Using 26 climate models from the Coupled Model Intercomparison Project Phase 5 (CMIP5), climatology and the interannual variability of the annual mean Hadley circulation are evaluated. The results show that most of 26 models perform well in simulating the spatial structure of the climatology of the annual mean Hadley circulation, but the results derived from these models are generally weaker than that derived from the reanalysis dataset. Eighteen models can properly simulate well the asymmetric mode and symmetric mode of the annual mean Hadley circulation variability. Two models can only simulate asymmetric mode or symmetric mode and the other two models simulate reversed sequences of asymmetric mode and symmetric mode. The possible reason why some models cannot properly simulate the asymmetric mode and symmetric mode is that these models do not properly simulate the structure of zonal mean sea surface temperature (SST). Especially, not properly simulating variances of symmetric and asymmetric components of the SSTA will lead to reversed sequence of symmetric mode and asymmetric mode. And not properly simulated either symmetric or asymmetric component of the SSTA will lead to inability in simulating symmetric mode or asymmetric mode. On the other hand, some models properly simulate the asymmetric mode and symmetric mode, but do not properly simulate the responses to SST change. These models can not reflect the air sea coupling processes in associated with the Hadley circulation, therefore they should be taken more care when classify the models into groups.

Basic Features of Climate Change in North China during 1961–2010
W. Guo, S. Hong-Bo, M. Jing-Jin, Z. Ying-Juan, W. Ji, S. Wen-Jun, Z. Zi-Yin

Advances in Climate Change Research (2013).

Abstract
The spatial and temporal variations of some important near-surface climate parameters and extreme climate events in North China during 1961–2010 are analyzed by using 94 meteorological stations’ data in the study area. Results show that the annual mean surface air temperature in North China increased at the rate of 0.36°C per decade, higher than the national average in the same period. Increasing was particularly significant since the mid-1980s, with maximum increase in the middle and northeastern parts of Inner Mongolia. Increasing rate of the annual mean minimum temperature is much higher than that of the maximum temperature, which results in the decrease of the annual mean diurnal temperature range. Noticeable decrease is also observed in the frequency of cold wave. Annual precipitation shows a slight decreasing trend, with more pronounced decrease in southern Shanxi and eastern Hebei provinces, which is mainly represented as decreasing in contribution rates of rainstorm and heavy storm in flood-season (May to September). During 1961–2010, North China is characterized by a noticeable reduction in annual extreme precipitation, and an increase in high-temperature days over most parts, as well as more frequent droughts. There are remarkable reductions in annual sunshine duration and mean wind speed, associated with the most significant reduction of mean wind speed in midwestern and eastern parts of Inner Mongolia. Meanwhile, North China has experienced a noticeable decrease/increase in annual mean sanddust/haze days during the study period. However, there is no significant trend in fog days, except a pronounced decrease since the 1990s. Guo, W.-L., H.-B. Shi, J.-J.

Earth observation big data for climate change research
H. Guo, L. Zhang, L. Zhu

Advances in Climate Change Research (2015). Vol. 6 pp. 108-117

Abstract
Earth observation technology has provided highly useful information in global climate change research over the past few decades and greatly promoted its development, especially through providing biological, physical, and chemical parameters on a global scale. Earth observation data has the 4V features (volume, variety, veracity, and velocity) of big data that are suitable for climate change research. Moreover, the large amount of data available from scientific satellites plays an important role. This study reviews the advances of climate change studies based on Earth observation big data and provides examples of case studies that utilize Earth observation big data in climate change research, such as synchronous satellite–aerial–ground observation experiments, which provide extremely large and abundant datasets, Earth observational sensitive factors (e.g., glaciers, lakes, vegetation, radiation, and urbanization), and global environmental change information and simulation systems. With the era of global environment change dawning, Earth observation big data will underpin the Future Earth program with a huge volume of various types of data and will play an important role in academia and decisionmaking. Inevitably, Earth observation big data will encounter opportunities and challenges brought about by global climate change.

Governing Climate Change Adaptation in the EU and China: An Analysis of Formal Institutions
M. Gemmer, A. Wilkes, L. Vaucel

Advances in Climate Change Research (2011). Vol. 2(25) pp. 1-11

Abstract
Both the European Union (EU) and China are culturally, economically, climatologically and environmentally diverse polities. The EU is a multi-state grouping of economically developed democratic countries, while China is a unitary sovereign state and a developing economy with a strong government bureaucracy. Our hypothesis is that given their diverse political systems, the EU and China would develop different kinds of systems for the governance of adaptation to climate change. We test this hypothesis through a comparative analysis of policy documents from the two study areas, in which we examine framework policies, programmatic actions and specific actions that have been adopted to date in order to address climate change, with a specific focus on the water sector. We find that climate change adaptation began to be addressed through formal policy on a similar timeline in the two regions. The EU and China are also similar in that they use framework laws and existing sectoral policy, such as for the water sector. We find that the EU has primarily relied on integration of climate change adaptation concerns through legal instruments which set a framework for implementation of adaptation policy. In China, specific actions to be incorporated in socio-economic development plans under the existing legislation on adaptation have been the main mode for integrating adaptation into sectoral actions, though the future trend may be to develop more regulations.

Chinas response to climate change issues after Paris Climate Change Conference
Y. Gao

Advances in Climate Change Research (2016). Vol. 7 pp. 235-240

Abstract
The Paris Climate Change Conference was successfully concluded with the Paris Agreement, which is a milestone for the world in collectively combating climate change. By participating in IPCC assessments and conducting national climate change assessments, China has been increasing its understanding of the issue. For the first time, Chinas top leader attended the Conference of the Parties, which indicates the acknowledgement of the rationality and necessity of climate change response by China at different levels. Moreover, this participation reflects Chinas commitment to including climate change in its ecology improvement program and pursuing a low-carbon society and economy. In order to ensure the success of the Paris Conference, China has contributed significantly. Chinas constructive participation in global governance shows that China is a responsible power. These principles such as the creation of a future of win–win cooperation with each country contributing to the best of its ability, a future of the rule of law, fairness, and justice, and a future of inclusiveness, mutual learning, and common development will serve as Chinas guidelines in its efforts to facilitate the implementation of the Paris Agreement and participate in the design of international systems.

Analysis of Surface Air Temperature Change in Macao During the Period 1901–2007
S. Fong, C. Wu, A. Wang, X. He, T. Wang, K. Leong, U. Lai, B. Leong

Advances in Climate Change Research (2010).

Abstract
Change related to climate in Macao was studied on the basis of daily temperature observations over the period 1901–2007. The result shows that annual mean surface air temperature in Macao as a whole rose with a warming rate of about 0.066 °C per 10 years in the recent 107 years. The most evident warming occurred in spring and winter. The interdecadal variations of the seasonal mean temperature in summer and winter appeared as a series of waves with a time scale of about 30 years and 60 years, respectively. The annual mean minimum temperature increased about twice as fast as the annual mean maximum temperature, resulting in a broad decline in the annual mean diurnal range. The interdecadal variations of annual mean maximum temperature are obviously different from those of annual mean minimum temperature. It appears that the increase in the annual mean maximum temperature in the recent 20 years may be part of slow climate fluctuations with a periodicity of about 60 years, whereas that in the annual mean minimum temperature appears to be the continuation of a long-term warming trend.

Trends in Monthly Temperature and Precipitation Extremes in the Zhujiang River Basin, South China (1961–2007)
T. Fischer, M. Gemmer, L. Liu, B. Su

Advances in Climate Change Research (2010).

Abstract
Monthly temperature and precipitation time-series for the Zhujiang River Basin are analyzed in order to identify changes in climate extremes. Daily temperature and precipitation data from 1961 to 2007 of 192 meteorological stations are used. Two temperature indicators (monthly mean and monthly maximum mean) and three precipitation indicators (monthly total, monthly maximum consecutive 5-day precipitation, and monthly dry days) are analyzed. Tendencies in all five indicators can be observed. Many stations show significant positive trends (above the 90% confidence level) for monthly mean temperatures and monthly maximum mean temperatures. For all months, a significant increase in temperature from 1961 to 2007 can be observed in the entire basin with the coastal area in particular. Positive trends of precipitation extremes can be observed from January to March. Negative trends are detected from September to November. The number of dry days in October increased significantly at 40% of all meteorological stations. Stations with changes of monthly precipitation extremes are scattered over the Zhujiang River Basin. An aggregation of heat waves and droughts can be detected which is accompanied by significant increases of temperature extremes and the negative tendencies in precipitation extremes. The detection of tendencies in climate extremes essentially relies on a good data quality and high station density. Fischer, T., M. Gemmer, L.

Definition of Business as Usual and Its Impacts on Assessment of Mitigation Efforts
T. Fei, X. Shuang-Qing

Advances in Climate Change Research (2012). Vol. 3(25) pp. 212-219

Abstract
Business as Usual (BaU) scenario in developing countries has been a debated issue in climate change negotiations. This paper analyzes different definitions of BaU and points out that the major difference among these definitions is how to set the starting point of BaU projections, that is the so called base year. Some international institutions use current policy scenarios to project a BaU trajectory of developing countries. Such definition will lead to an underestimation of BaU emissions of developing countries and thus an underestimation of mitigation efforts. This paper concludes with a suggestion to use a without policy scenario with a clear base year as definition of BaU. Such a definition will set an objective benchmark to assess mitigation efforts of developing countries. Teng, F., and S.-Q. Xu, 2012: Definition of Business as Usual and its impacts on assessment of mitigation efforts. Adv. Clim. Change Res., 3 (4), doi: 10.3724/SP.J.1248.2012.00212.

Estimating the Macroeconomic Costs of CO2 Emission Reduction in China Based on Multi-objective Programming
Y. Fan, X. Zhang, L. Zhu

Advances in Climate Change Research (2010). Vol. 1 pp. 27-33

Abstract
This paper estimates the macroeconomic costs of CO2 emission reduction in China employing the input-output analysis with the multi-objective programming approach. The results show that the effect of reducing CO2 emissions on China’s economy is significant. Under the present conditions, the estimated macroeconomic costs of CO2 emission reduction in 2010 for China are approximately 3, 100–4, 024 RMB t - 1 . The stronger the abatement actions, the higher the macroeconomic costs of per unit emission reduction would be. Excavation industry, oil industry, chemical industry, and metal smelting industry have high potential to abate their CO2 emissions. Fan, Y., X. Zhang, and L.

Analysis of Global CCS Technology, Regulations and Its Potential for Emission Reduction with Focus on China
Y. Fan, L. Zhu, X. Zhang

Advances in Climate Change Research (2011). Vol. 2(25) pp. 57-66

Abstract
This paper introduces the development of Carbon Capture and Storage (CCS) technology, the progress in CCS demonstration projects, and regulations and policies related to CCS. Barriers and limitations for the large-scale deployment of CCS are discussed. CCS and different technological solutions for emission reduction (e.g., energy conservation and renewable energy) are compared. The analysis shows that China should carefully evaluate the negative impacts of CCS deployment and needs to enhance the research and development input in CCS in order to master core technologies of CCS systems. Furthermore, CCS incentives should depend on actual CCS development. Based on the current situation, China may need to focus on retrofitting existing thermal power plants with CCS technology, so CCS can be promoted for future large-scale application. Fan, Y., L. Zhu, and X. Zhang, 2011: Analysis of global CCS technology, regulations and its potential for emission reduction with focus on China. Adv. Clim. Change Res., 2 (2), doi: 10.3724/SP.J.1248.2011.00057.

A climatic environmental performance assessment method for ecological city construction: Application to Beijing Yanqi Lake
X. Fang, C. Cheng, Y. Liu, W. Du, -. Xiao, B. Dang

Advances in Climate Change Research (2015). Vol. 6 pp. 23-35

Abstract
In contrast to the input perspective for evaluating planning metrics, this research takes the climatic environmental output effects as the starting point for assessing ecological city construction. Based on approaches such as observation data analysis, meteorological model simulation, and remote sensing, a set of climatic environmental performance assessment methods is developed and established. These methods mainly focus on surface ventilation assessment and urban thermal environment assessment. With the Yanqi Lake ecological development demonstration area located in Huairou district, Beijing as an example, the assessment of the local climatic environment before and after the construction are conducted, and relevant policy suggestions for urban planning and construction are presented. The results show that after development, the ventilation capacity will decrease overall and the ventilation potential index will decrease from 0.53 to 0.44. While this is not a large reduction, and is still at a favorable level, the ventilation potential in some local areas will markedly decrease. Furthermore, the thermal environment will become poorer to some extent, the urban heat island (UHI) area and intensity will increase compared with the current situation, continuous heat islands may occur in local areas, the UHI potential index of the core area will rise from 0.0878 to 0.1217 (still a favorable level). Therefore, urban surfaces should be carefully developed and arranged during planning. It is suggested that the negative impacts of large areas of urban construction on the local climatic environment in the Yanqi Lake could be mitigated by 1) strengthening the airflow by introducing fresh, cold, northwesterly air via constructed ventilation corridors, 2) increasing the number of ecological cold sources, particularly for water bodies and green belts to prevent the UHI in the southern region of Yanqi Lake from becoming linked with each other, and 3) considering a pre-program before sub-domain and building planning to obtain optimum building locations. Different construction standards should be developed for different ventilation potential and UHI intensity levels. For strong heat island areas, land areas should be reserved to serve as cold sources.

Presentations to the VII International Conference on Computational Methods in Marine Engineering (Marine 2017).

Abstract
A finite element method for the solution of the up-to-second-order wave diffraction-radiation problem in the time-domain is proposed. The solver has been validated against experimental data available for the HiPRWind semisubmersible platform (designed for floating wind turbines). To perform the validation, the wave diffraction-radiation solver is coupled to a body dynamics and mooring solvers in the time-domain. The HiPRWind movements and mooring forces have been compared for a large number of test cases, including decay tests, bichromatic, and irregular waves. Good agreement has been found for both, body movements and mooring forces.

Chinas low-carbon transition for addressing climate change
X. Du

Advances in Climate Change Research (2016). Vol. 7 pp. 105-108

Abstract
This study discusses high-carbon characteristics, the unsustainability of Chinas development, and the fact that China needs to transform its development mode. Chinas low-carbon transition must include industry structure adjustment, energy saving and efficiency increases, energy structure improvement, carbon sink development, adaptation capability, and low-carbon pilot schemes. Low-carbon urbanization is a key measure in Chinas low-carbon transition. Chinas urbanization faces high-carbon risks. Thus, this study presents a roadmap for transforming urbanization into a low-carbon one. The transition to low-carbon urbanization is a common trend in the developing world. There is a lot of room for international cooperation.

Essence and resolution of international climate negotiation
X. Du

Advances in Climate Change Research (2014). Vol. 5 pp. 149-152

Abstract
In essence, international climate negotiation is a serious and responsible global effort, despite various conflicts, to establish a rational international climate regime. In essence, tackling climate changes is leading the globe to actualize sustainable development of all humankind along the low-carbon, green, and cyclic-development path. Thus, climate negotiation should be driving all parties to achieve a global climate regime arrangement in a constructive way. Therefore, this paper suggests focusing on the following three major recommendations: early developed countries take the lead in committing positively to absolute emission reduction, the developing countries contribute according to their abilities and stages of development, the developed countries perform real deeds using their funds and technology. Based on substantial breakthrough that would be made, progressive supplement and improvement could be accomplished through the mechanism of review and adjustment under the Convention framework. This path represents a combination of bottom-up and top-down. The ultimate way out of international climate negotiation lies in win-win cooperation. Profound reasons for China to participate proactively and practically in international climate negotiation, based on its actual conditions, are the internal wants and needs of its scientific and sustainable development, as well as the undertaking of international responsibilities as a responsible, large, developing country.

Chinese Public’s Willingness to Pay for CO2 Emissions Reductions: A Case Study from Four Provinces/Cities
H. Duan, L. Yan-Li, L. Yan

Advances in Climate Change Research (2014). Vol. 5 pp. 100-110

Abstract
Contingent Valuation Method (CVM) was used to investigate the Chinese public’s willingness to pay (WTP) for a policy to reduce CO2 emissions. Face to face interviews were conducted to collect 1, 653 valid questionnaires from Beijing, Shanghai, Shandong province, and Fujian province. A model was constructed to understand the factors that influence WTP. The results indicate that the Chinese public is willing to pay CN¥201.86 annually to support the policy of reducing greenhouse gas emissions. Participants from Beijing show the highest WTP, followed by participants from Fujian and Shandong, while those from Shanghai report the lowest WTP. The findings reveal that participants with higher income, higher satisfaction with their current life, and awareness of climate issues are willing to pay more for CO2 emissions reductions. In addition, those who are young, male and members of the Communist Party also indicate a higher WTP. The results imply that translating the public’s willingness to protect climate into actions should be taken into account in China’s low carbon policy. There is a need to consider the difference in degree of willingness, among different social groups, to pay for emissions reductions if the market-based mechanisms such as carbon tax were designed to facilitate emissions reductions.

An overview of black carbon deposition and its radiative forcing over the Arctic
T. Dou, C. Xiao

Advances in Climate Change Research (2016). Vol. 7 pp. 115-122

Abstract
This paper gives an overview of the current understanding of the observations of black carbon (BC) in snow and ice, and the estimates of BC deposition and its radiative forcing over the Arctic. Both of the observations and model results show that, in spring, the average BC concentration and the resulting radiative forcing in Russian Arctic > Canadian and Alaskan Arctic > Arctic Ocean and Greenland. The observed BC concentration presented a significant decrease trend from the Arctic coastal regions to the center of Arctic Ocean. In summer, due to the combined effects of BC accumulation and enlarged snow grain size, the averaged radiative forcing per unit area over the Arctic Ocean is larger than that over each sector of the Arctic in spring. However, because summer sea ice is always covered by a large fraction of melt ponds, the role of BC in sea ice albedo evolution during this period is secondary. Multi-model mean results indicate that the annual mean radiative forcing from all sources of BC in snow and ice over the Arctic was ∼0.17 W m−2 . Wet deposition is the dominant removal mechanism in the Arctic, which accounts for more than 90% of the total deposition. In the last part, we discuss the uncertainties in present modeling studies, and suggest potential approaches to reduce the uncertainties.

Spatial and Temporal Variations of Heat Waves in China from 1961 to 2010
Y. Dian-Xiu, Y. Ji-Fu, C. Zheng-Hong, Z. You-Fei, W. Rong-Jun

Advances in Climate Change Research (2010). pp. 66-73

Abstract
Daily maximum temperatures from 753 stations across China and the heat wave indicators are used to study the temporal and spatial characteristics of heat wave intensity, frequency and heat wave days in China over the period of 1961–2010. The results show that high frequency, long duration and strong intensity of heat waves occurred in the Jianghuai area, Jiangnan area, and eastern Sichuan Basin. The highest frequency and the longest duration are located in northern Jiangxi and northern Zhejiang provinces, and the highest intensity in northern Zhejiang province is even more prominent. The frequency, heat wave days and intensity showed a general increasing trend in the past 50 years, while decadal characteristics are also observed with a decreasing trend from the 1960s to the early 1980s and increasing trend from the end of the 1980s to 2010. The regional variations demonstrate a significant increasing trend in the northern and western parts of North China, central-northern part of Northwest China, the central part of South China, the Yangtze River Delta and the southern Sichuan Basin, with an obvious decreasing trend in the southern Huanghuai area, northern Jianghuai area and Hanjiang River Basin.

Public Perceptions of Cryosphere Change and the Selection of Adaptation Measures in the Ürümqi River Basin
M. Deng, H. Zhang, W. Mao, Y. Wang

Advances in Climate Change Research (2011). Vol. 2(25) pp. 149-158

Abstract
This study focuses on the characters of public perceptions on climate and cryosphere change, which are based on a questionnaire survey in the Ürümqi River Basin. In comparison with scientific observation results of climate and cryosphere change, this paper analyzes the possible impact of the change on water resources and agriculture production in the area. Perceptions of most respondents on climate and cryosphere changes confirm the main objective facts. For the selection of adaptation measures addressing the shortage of water resource, the results are as follows: most people preferred to choose the measures like “policy change” and “basic facility construction” which are mostly implemented by the government and the policy-making department, some people showed more preference to the measures of avoiding unfavorable natural environment, such as finding job in or migrating to other places. The urgency of personal participation in the adaptation measures is still inadequate. Some adaptation measures should be implemented in line with local conditions and require the organic combination of “resource-development” with “water-saving”. Deng, M., H. Zhang, W.

Method for Calculating CO2 Emissions from the Power Sector at the Provincial Level in China
M. Cui-Mei, G. Quan-Sheng

Advances in Climate Change Research (2014). Vol. 5 pp. 92-99

Abstract
Based on the detailed origins of each province’s electricity consumption, a new method for calculating CO2 emissions from the power sector at the provincial level in China is proposed. With this so-called consumer responsibility method, the emissions embodied in imported electricity are calculated with source-specific emission factors. Using the new method, we estimate CO2 emissions in 2005 and 2010. Compared with those derived from the producer responsibility method, the power exporters’ emissions decreased sharply. The emissions from the power sector in Inner Mongolia, the largest power exporter of China, decreased by 109 Mt in 2010. The value is equivalent to those from Shaanxi’s power production and Canada’s power and heat production. In contrast, the importers’ emissions increased substantially. The emissions from the power sector in Hebei, the largest power importer of China, increased by 74 Mt. Emissions of Beijing, increased by 60 Mt (320%), in 2010. Thus, we suggest that the Chinese government should take the emissions, as calculated from the consumption perspective, into account when formulating and assessing local CO2 emission reduction targets.

Abstract
On the basis of data from the period 1971–2007, and by applying trend analysis, a study on formation, disappearance and duration of lake ice cover on the Morskie Oko Lake in the Tatra Mountains in southern Poland was carried out. The results show decreasing trends in the maximum thickness of winter lake ice cover and in duration of lake ice phenomena, while air temperature recorded at the same period at the foot of the Tatra Mountains shows increasing trend. There are strong relationships between the course of lake ice phenomena and air temperature. Choiński, A., L. Kolendowicz, J.

Moving past the rhetoric: Policy considerations that can make Sino-African relations to improve Africas climate change resilience and the attainment of the sustainable development goals
D. Chirambo

Advances in Climate Change Research (2016). Vol. 7 pp. 253-263

Abstract
Climate change is a threat to the attainment of the Sustainable Development Goals (SDGs) in sub-Saharan Africa as its impacts can lead to increased incidences of poverty and inequality which can subsequently lead to a 12% decline in the Human Development Index (HDI) for sub-Saharan Africa. Emerging countries such as China have the potential to support Africa to achieve the SDGs by pioneering South–South Climate Finance (SSCF) modalities. In order to increase knowledge on climate informed development and the role of China in global climate governance, the paper examined various research articles, case studies, policy briefs and project reports. Sino-African aid, investments and trade were noted as essential in mitigating Africas climate change vulnerabilities which induce poverty traps and inequality. Some African countries were noted to have a comparative advantage in environmental standards over China but lacked the initiative to use this comparative advantage to enhance the Forum on China–Africa Cooperation (FOCAC) and assist China to have a sustainable growth trajectory. The paper concludes that SSCF modalities can enhance climate risk management in Africa if they focus on improving financial inclusion and improving climate finance flows towards climate change adaptation activities in Africa. Additionally, to increase the effectiveness and impact of Chinese climate finance support to Africa, African policymakers should not allow political and market forces to decide how climate related support from China should be allocated as decisions based on political and market forces could potentially promote an inequitable distribution of funds and ignore the most vulnerable countries and regions.

Variation of Extreme Precipitation over Large River Basins in China
Y. Chen, X. Chen, G. Ren

Advances in Climate Change Research (2011). Vol. 2(25) pp. 108-114

Abstract
A new available dataset of daily observational precipitation is used to study the temporal and spatial variability of extreme precipitation events for 1956–2008 in the ten large river basins of China. The maximum daily rainfall and heavy precipitation days (≥ 50 mm d–1 ) are analyzed for the basins of the Songhua River, Liaohe River, Haihe River, Yellow River, Northwest China Rivers, Huaihe River, Yangtze River, Pearl River, Southeast China Rivers, and Southwest China Rivers. The results indicate that the maximum daily rainfall was increasing in southern river basins, while it was decreasing in northern river basins, which leads to no discernible increasing or decreasing trend in the maximum daily rainfall of whole China, especially after 2001. The national averaged heavy precipitation days shows an insignificant increase. However, a rise in heavy precipitation days of southern river basins and a decline of northern river basins are observed. Chen, Y., X. Chen, and G.

Urbanization effect on precipitation over the Pearl River Delta based on CMORPH data
S. Chen, W. Li, Y. Du, C. Mao, L. Zhang

Advances in Climate Change Research (2015). Vol. 6 pp. 16-22

Abstract
Based on the satellite data from the Climate Prediction Center morphing (CMORPH) at very high spatial and temporal resolution, the effects of urbanization on precipitation were assessed over the Pearl River Delta (PRD) metropolitan regions of China. CMORPH data well estimates the precipitation features over the PRD. Compared to the surrounding rural areas, the PRD urban areas experience fewer and shorter precipitation events with a lower precipitation frequency (ratio of rainy hours, about 3 days per year less), however, short-duration heavy rain events play a more significant role over the PRD urban areas. Afternoon precipitation is much more pronounced over the PRD urban areas than the surrounding rural areas, which is probably because of the increase in short-duration heavy rain over urban areas.

Shares Differences of Greenhouse Gas Emissions Calculated with GTP and GWP for Major Countries
W. Chang-Ke, L. Xin-Zheng, Z. Hua

Advances in Climate Change Research (2013). Vol. 4(25) pp. 127-132

Abstract
The global warming potential (GWP) and global temperature potential (GTP) are two common metrics to calculate the CO2 equivalent of greenhouse gases (GHGs). If the country’s GHG emissions are calculated with GTP instead of GWP, the shares of the EU, USA, Japan, Canada and South Africa rise in the period 1990–2005, and those of Brazil, Australia, China, India, Mexico and Russia decrease. From 2015 to 2030, the projected shares of the EU, USA, Japan and China will increase, but those of Russia, Canada, Australia, India, Mexico and Brazil will decrease. The reduced shares of Brazil and Australia and increased share of the EU might be one of the important reasons that Brazil and Australia suggested to adopt GTP instead of GWP as early as possible, but the EU opposed it.

Modeling an emissions peak in China around 2030: Synergies or trade-offs between economy, energy and climate security
Q. Chai, H. Xu

Advances in Climate Change Research (2014). Vol. 5 pp. 169-180

Abstract
China has achieved a political consensus around the need to transform the path of economic growth toward one that lowers carbon intensity and ultimately leads to reductions in carbon emissions, but there remain different views on pathways that could achieve such a transformation. The essential question is whether radical or incremental reforms are required in the coming decades. This study explores relevant pathways in China beyond 2020, particularly modeling the major target choices of carbon emission peaking in China around 2030 as China-US Joint Announcement by an integrated assessment model for climate change IAMC based on carbon factor theory. Here scenarios DGS-2020, LGS2025, LBS-2030 and DBS-2040 derived from the historical pathways of developed countries are developed to access the comprehensive impacts on the economy, energy and climate security for the greener development in China. The findings suggest that the period of 2025–2030 is the window of opportunity to achieve a peak in carbon emissions at a level below 12 Gt CO2 and 8.5 t per capita by reasonable trade-offs from economy growth, annually −0.2% in average and cumulatively −3% deviation to BAU in 2030. The oil and natural gas import dependence will exceed 70% and 45% respectively while the non-fossil energy and electricity share will rise to above 20% and 45%. Meantime, the electrification level in end use sectors will increase substantially and the electricity energy ratio approaching 50%, the labor and capital productivity should be double in improvements and the carbon intensity drop by 65% by 2030 compared to the 2005 level, and the cumulative emission reductions are estimated to be more than 20 Gt CO2 in 2015–2030.

Biodiversity and Climate Change Adaptation in Australia: Strategy and Research Developments
T. Booth

Advances in Climate Change Research (2012). Vol. 3(25) pp. 12-21

Abstract
Many countries are developing national strategies and action plans aimed at minimising the negative impacts of climate change on biodiversity. The purpose of this paper is to provide a brief overview not only of strategies and plans that have been developed in Australia, but also of research that has been carried out in Australia by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) Climate Adaptation Flagship to assist the development of future strategies and plans. Major points are summarised from key policy documents such as the National Biodiversity and Climate Change Action Plan 2004–2007, and Australia’s Biodiversity Conservation Strategy 2010–2030, as well as the 2009 report on “Australia’s Biodiversity and Climate Change”. Within the first three years of its existence, the Natural Ecosystems theme in CSIRO Climate Adaptation Flagship has carried out studies analysing impacts and identifying potential adaptations across the whole of Australia’s vast terrestrial and marine environments. Techniques used in these studies could be applied easily in other countries and could assist the development of more effective national strategies and adaptation action plans for the conservation of biodiversity under climate change.

Low Carbon Society in China: Research and Practice
C. Bo-Feng, W. Jin-Nan, Y. Wei-Shan, L. Lan-Cui, C. Dong

Advances in Climate Change Research (2012). Vol. 3(25) pp. 106-120

Abstract
This paper aims to provide an overall image in terms of low carbon society (LCS) and its development in China. It mainly introduced and analyzed low carbon development which was addressed as crucial initiative for implementation of LCS in China. A comparative analysis was carried out on concepts and experiences of LCS between China and developed countries. The trends and characteristics of CO2 emissions in China have also been analyzed. Because of large amount of CO2 emissions generated in the production process and relatively small amount of CO2 emissions in the consumption process, China is facing a severe challenge of imbalance in economic growth and CO2 emissions. If the consumption and production pattern of developed countries are duplicated, China is very likely to experience a development pattern of boosting economic growth and improving living standards significantly but meanwhile risking and suffering by large amount of resources consumption and CO2 emissions. Thus, a comprehensive, systematic and scientific scheme for implementing a low carbon society is urgently needed in China. Through literature research, mainstream perspectives of scholars with respect to development of LCS are concluded. In the meantime, CO2 emissions reduction target, carbon taxation and different debated issues are also presented. The achievements, China has made, consist of concrete actions taken by local governments, some new policies and regulations for carbon reduction at national level, in particular energy-saving and renewable energy policies proposed in the 11th Five-Year Plan (2005–2010). Carbon trading markets and carbon capture and starage technology have also made progress in China. There are still many limitations and barriers remaining and in need to be solved in the next steps.

Estimation of Methane Emissions from Municipal Solid Waste Landfills in China Based on Point Emission Sources
C. Bo-Feng, L. Jian-Guo, G. Qing-Xian, N. Xiao-Qin, C. Dong, L. Lan-Cui, Z. Ying, Z. Zhan-Sheng

Advances in Climate Change Research (2014). Vol. 5 pp. 81-91

Abstract
The methane (CH4 ) emissions from municipal solid waste (MSW) landfills in China in 2007 were estimated based on database of the three-dimensional emission factors matrix and point sources, by an IPCC recommended FOD (firstorder decay) model. The location, capacity and age of landfills constitute the three dimensions of the emission factors matrix, which were obtained by laboratory analysis and in situ investigation. Key parameters such as waste composition, degradable organic carbon ratio, CH4 correction factor, oxidation factor and recovery rate, were carefully analyzed in terms of these three dimensions. The point sources database consists of 2, 107 MSW landfills in cities and towns of China in 2007. The results show that the CH4 emissions from MSW landfills were 1.186 Mt in 2007. Compared with the CH4 emissions of 2.20 Mt in 2005, the significant discrepancy mainly comes from statistical data of landfills, e.g., number of landfills and amount of waste disposed in landfills. CH4 emissions were lower than 700 t for most of the landfills, whereas there were 279 landfills with emissions larger than 1, 000 t, and only 10 landfills with emissions larger than 10, 000 t. Jiangsu province ranks the largest emitter with 98, 700 t while Tibet is the smallest emitter with 2, 100 t. In general, the emissions from eastern provinces, such as Jiangsu, Guangdong and Zhejiang, were larger than those from western provinces, such as Ningxia, Tibet and Qinghai.

Comparison of nitrous oxide (N2 O) emissions calculations at a Swedish wastewater treatment plant based on water concentrations versus off-gas concentrations
C. Baresel, S. Andersson, J. Yang, M. Andersen

Advances in Climate Change Research (2016). Vol. 7 pp. 185-191

Abstract
Total nitrous oxide (N2 O) emissions from a conventional active sludge process were calculated using a mathematical emission model and dissolved N2 O in the water phase by a N2 O water sensor. Calculated emissions showed good agreement with measured emissions based on concentrations and airflow in the off-gas ventilation system from the covered process. Various tests for a wide range of potentially affecting parameters indicated robust and reliable emission estimations by the model. Thus, common uncertainties in input data would still provide good emission estimations. Measurements of dissolved N2 O required low maintenance and N2 O emission monitoring based on such measurements might therefore be considered as a significant practical improvement. This would be advantageous especially in non-enclosed wastewater treatment plants (WWTPs) otherwise requiring complex off-gas measurements. As the sensor is connected directly to the WWTPs monitoring and control system, emissions calculations could be incorporated.

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

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.

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).

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.

M. Michiani, J. Asano

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.

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.

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.

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.
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 [...]

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.

Frontiers of Architectural Research (2012). Vol. 1 pp. 295-304

Abstract
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.

Frontiers of Architectural Research (2013). Vol. 2 pp. 362-372

Abstract
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.

Frontiers of Architectural Research (2016). Vol. 5 pp. 279-289

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).
