Abstract:
In this research multiple-regression analysis with stepwise selection method was employed for
investigating the effect of 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. Depends on house orientations in two directions of SE and SW and by using statistical data, E cooling in urban residences was analyzed. The autocorrelation in the residuals, checked by Durbin- Watson test, was not existed. By investigating the relations between average Evr and E Cooling in each group, it can be proved that climatic orientated houses can achieve lower E Cooling, owing to SE desirable orientation. The percentage of Evr in SW houses is 28.89 % and in SE it is 15.72 %, so choosing the building orientation is important to reduce energy consumption. Finally, the concluding remarks were indicated.
Machine summary:
"2014 In this research multiple-regression analysis with stepwise selection method was employed for investigating the effect of vertical building envelopes solar radiation (Evr) on cooling energy consumption (E cooling) in residential sector.
Energy consumption, Solar radiation, Residential sector, Building orientation, Cooling need, Regression INTRODUCTION There is a growing concern about energy use and its implications for the environment (Wan et al.
Kaza (2010) used quintile regression analysis to appear the effects of various factors on entire distribution on the energy consumption spectrum instead of focusing on the conditional average by using residential determination the effect of building orientation (BO) on electricity cooling energy consumption (E Electricity) in middle- life urban residence annually and monthly in semi-arid climate (Shiraz).
E cooling: cooling energy consumption of the building was calculated based upon summation of the electricity bills of the sample houses in different time intervals, by means of source- site ratio (EIA Report, 2011).
In present paper, multiple-regression analysis was deployed to determine the effect of building envelopes solar radiation on cooling energy consumptions.
