Résumé
Buildings consume a significant proportion of the total energy used worldwide and consequently emit masses of green gases. Therefore, energy management in the buildings plays an important role in formulating sustainable development strategies. There is a growing interest in zero energy buildings (ZEBs) in recent years. Several countries have adopted or considered establishing ZEBs as their future building energy targets to address the problems concerning the depletion of energy resources and the environmental issues. In general, ZEBs involve two design strategies. Firstly, to minimize the need for energy consumption in buildings (especially for heating and cooling) through energy efficient measures and secondly to adapt renewable energy technologies to fulfil the remaining energy needs. The aim of this thesis is to do a comprehensive investigation of design strategies in order to select proper solution applied in buildings and proposed solutions to attain Net Zero Energy Buildings (Net ZEBs) in hot climates. For the undertaken subject of this study, firstly the concept of ‘Zero Energy/Emission Building’ (ZEB) is to be analyzed in detail. For this purpose, ZEB building strategies in terms of energy production and consumption for hot climate areas have been considered. The thesis contains three chapters. The first chapter focuses on the review and analysis of main design principles, technologies and solutions. The objective is to reach an energy balance in residential building in hot climate zone by selecting the proper methods for reducing energy in terms of thermal and visual comfort and producing energy from renewable energy sources. In the third chapter the factors discussed in chapter 2 are evaluated by selecting case studies in hot and arid and hot and humid climates. Finally, chapter 3 concludes the study by comparing the reported data. The result shows similar patterns, the designer aims to minimize energy by understanding the best local passive systems and optimizing them by recent technologies such as sufficient materials and most effective insulation. Similar to the literature findings, most of the energy for the case studies is produced by solar radiation in hot climate regions. Nevertheless, attention should be paid about heat gain by radiation using proper insulation and envelope design, while Occupants of the modern buildings expect comfortable conditions combined with balance in energy consumption to reduce environmental effects as well as energy cost.
