It summarizes the simulation analysis to determine the effectiveness of envelope construction in reducing total electrical consumption for residential buildings in Egypt. This paper studied the effect of the building envelope construction, orientation, window opening area as a ratio of wall area, and the glazing type for Cairo and Alexandria. It was determined that for most residential buildings in Egypt with SHGC values above 0.61, increases the total electrical consumption by 25%. Roof and wall insulation provides significant energy savings, 40% for the roofs and 12% for walls.展开更多
文摘This paper evaluates the potential of building envelope to save energy associated with the total electricity consumed. It summarizes the simulation analysis to determine the effectiveness of envelope construction in reducing total electrical consumption for residential buildings in Egypt. This paper studied the effect of the building envelope construction, orientation, window opening area as a ratio of wall area, and the glazing type for Cairo and Alexandria. It was determined that for most residential buildings in Egypt with SHGC values above 0.61, increases the total electrical consumption by 25%.
