Architectural Design Optimization of School Buildings for Reduction of Energy Demand in Hot & Dry Climates of Iran

School buildings as a major part of public buildings are considered as one of the basic consumers of energy in Iran. Based on building typology and occupancy patterns, school buildings have a great potentiality for energy optimization while providing thermal comfort. This study investigates the architectural design parameters such as orientation, optimum window to wall ratio, space organization, sun shading, building shape etc. which have a great impact on the energy demand. For the purpose of this study a typical elementary school has been selected, modeled and analyzed by integrating different design measures using a dynamic simulation software tool. The optimum amounts for various architectural design parameters are calculated. The results reveal that through energy efficient architectural design the primary energy demand of the studied case has reduced by 31% while keeping visual and thermal comfort compared to the existing building.
