Performance of Building Energy Efficiency by Orientation with Regression: a Case of Semi Desert in Iran

In this research multiple-regression analysis with stepwise selection method was employed for investigating the effectof vertical building envelopes solar radiation (Evr) on cooling energy consumption (E cooling) in residential sector.The high capacity of solar energy in semi-arid climate (Shiraz) can provide a part of buildings required energy. Dependson house orientations in two directions of SE and SW and by using statistical data, E cooling in urban residences wasanalyzed. The autocorrelation in the residuals, checked by Durbin- Watson test, was not existed. By investigatingthe relations between average Evr and E Cooling in each group, it can be proved that climatic orientated houses canachieve lower E Cooling, owing to SE desirable orientation. The percentage of Evr in SW houses is 28.89 % and in SEit is 15.72 %, so choosing the building orientation is important to reduce energy consumption. Finally, the concludingremarks were indicated.
