Abstract
This study aims to investigate optimum energy performance using simulation tools to provide thermal and visual comfort to occupants of office spaces in hot regions like Egypt where we have selected the case study. In addition to saving energy consumption by using sustainable materials for walls, ceilings, and windows, the study focuses on enhancing natural ventilation and natural lighting, through simulations of the building behavior and analyses of the thermal performance of building materials, finishing materials and glass types. Administrative buildings in Egypt do consume a great deal of energy compared to other building types.For that reason, was the purpose of this study to reduce energy consumption in Egyptian’s office buildings. Innovative digital simulation tools that offer new conduits to integrate both digital technologies and green architecture design practices are utilized in this study. The case study of this research are two office rooms at the administration building of Mansoura University, Dakahlia, Egypt.The results reveal that the saving proportion of energy consumption was 14% in the first case of the case study and 26.35% in the second case, in addition to 11.27% reduction of energy consumption of lighting system. Thus, improving occupants’ satisfaction with indoor air quality, glare, light levels, and perceived physiological overall comfort.
