Development of benchmark models for the Egyptian residential buildings sector

The aim of this study is to develop representative simulation building energy data sets and benchmark models for the Egyptian residential sector. This study reports the results of a recent field survey for residential apartment buildings in Egypt. Two building performance simulation models are created reflecting the average energy consumption characteristics of air-conditioned residential apartments in Alexandria, Cairo and Asyut. Aiming for future evaluation of the cost and energy affects of the new Egyptian energy standard this study established two detailed models describing the energy use profiles for air-conditioners, lighting, domestic hot water and appliances in respect to buildings layout and construction. Using EnergyPlus simulation tool the collected surveyed data was used as input for two building simulation models. The simulation models were verified against the apartment characteristic found in the survey. This paper presents details of the building models including the energy use patterns and profiles created for this study.

► Average energy use per apartment (T1 and T2) was 22.4 and 11 kWh/m2/year in Alexandria.
► Average energy use per apartment (T1 and T2) was 26.6 and 14 kWh/m2/year in Cairo.
► Average energy use per apartment (T1 and T2) was 31 and 18 kWh/m2/year in Asyut.
