INTEGRATING LAYOUT GEOMETRY WITH ARCHITECTURAL REQUIREMENTS TO ACHIEVE ENERGY-EFFICIENT OFFICE BUILDINGS IN EGYPT

Office buildings consume energy intensively for HVAC to maintain their thermal condition. As the form typology is a factor that affects the building's energy consumptions, this research focuses on the impact of form layout on office building energy consumption in hot desert climate. An extensive simulation process takes place to optimize the integration between energy-efficiency and design needs. The different tested design alternatives are the window to wall ratios, shading devices, and building orientations. The results exposed that building orientation has a significant role in improving the energy efficiency of longitudinal forms, while complex forms have a remarkable response to fenestration size and shading devices. In addition, the results found that the design alternatives optimization can play a significant role in improving the energy performance of high energy consumption forms.
