Abstract

Industrial halls are characterized with their relatively high roof-to-floor ratio, which facilitates ready deployment of renewable energy generation, such as photovoltaic (PV) systems, on the rooftop. To promote deployment of renewable energy generation, feed-in tariff (FIT) higher than the electricity rate is available in many countries to subsidize the capital investment. FIT comes in different forms. For net FIT, in order to maximize the economic benefit, surplus electricity generation at each hour is desirable. One way to achieve surplus electricity generation is by increasing generation capacity, which is synonymous to higher capital investment. In fact, surplus electricity generation can also be achieved by lowering the energy demand of the building. This particularly the case for industrial halls, which are usually subject to high energy demand for space conditioning in order to remove the excess heat gain due to the many power-intensive processes. Building energy performance simulation tools can be used to explore the different building design options that could lower the energy demand. In this paper, single-objective optimization on investment return will be deployed to study the cost effectiveness among different options in lowering energy demand. It will be demonstrated with a case study of a warehouse.

Abstract

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

Abstract

Transport energy modeling is a subject of current interest among transport engineers and scientists concerned with problems of sustainable transport. Transport energy planning is not possible without a reasonable knowledge of past and present energy consumption and likely future demands. In this study, three forms of the energy demand equations are developed in order to improve transport energy demand estimation efficiency for future projections based on genetic algorithm (GA) notion. The Genetic Algorithm Transport Energy Demand Estimation (GATEDE) model is developed using population, gross domestic product and vehicle-km. All equations proposed here are linear and non-linear, of which one is linear, second is exponential and third is quadratic. The quadratic form of the GATEDE model provided better-fit solution to the observed data and can be used with a high correlation coefficient for Turkey's future transport energy projections. It is expected that this study will be helpful in developing highly applicable and productive planning for transport energy policies. The GATEDE gives transport energy demand in comparison with the other transport energy demand projections. The GATEDE model plans the sectoral energy demand of Turkey until 2020.

Abstract

Efficient energy services are essential for economic growth, competitiveness, and human development. Globally, energy markets are undergoing a transformation: fossil fuel prices are responding to new and unpredictable dynamics, and new energy and information and communication technologies (ICT) are emerging and disrupting traditional market architectures. The 2030 development agenda for sustainable development adopted in September 2015 by the 193 countries of the United Nations General Assembly establishes sustainable energy as number seven of its 17 sustainable development goals (SDG7). It seeks to ensure access to affordable, reliable, sustainable, and modern energy for all. While much of the finance will have to come from the private sector, public finance - both national budgets and concessional transfers - will have a crucial role to play in helping set economies on the right path. So in this increasingly complex and rapidly changing context, how are Latin America and Caribbean (LAC) energy markets progressing? How will emerging disruptions and game changers influence the evolution and transformation of energy markets in LAC? How ready are existing markets and institutions to actively move toward the next frontiers of efficiency? What is needed to break through to the modern, efficient, secure, and sustainable energy systems needed to support the regional economy in the coming years? What investment will be needed and how is LAC poised to attract private finance? This report explores these questions and offers insights into paths and indicative actions needed to approach the next efficiency frontier. The report focuses on electricity and gas markets. The analysis acknowledges the varying conditions and challenges of different countries in the region. Intraregional variation is addressed through analysis of country groupings and selection of appropriate comparators, benchmarks, and best practice frontiers.
