The architectural design and environmental treatments have shown a large impact on environmental indoor performance and energy efficiency of buildings. Designers have been working on more efficient buildings using tools like the Leadership in Energy and Environmental Design (LEED) which is developed within the US Green Building Council (USGBC). This research aims to emphasize the passive design aspects of Islamic buildings in Historic Cairo, with special focus on Bayt Al-Suhaymi. Passive design elements such as architectural design aspects, orientation, façade treatments, selected materials and their impact on the energy efficiency levels are investigated in the research. Measurements of environmental indoor performance levels are carried out within the building where the temperature variance, humidity changes, TVOC and CO2 particles number are considered in a pilot survey. These measurements are employed in the assessment of the indoor environmental quality. Additionally, the building is assessed with reference to all other LEED criteria such as transportation, sustainable sites, water efficiency, energy, materials and innovation. LEED assessment revealed that Bayt Al-Suhaymi as an Islamic historic building could comply with the LEED rating system and could be a candidate to receive LEED gold certification.
