Energy-saving optimization based on residential building orientation and shape with multifactor coupling in the Tibetan areas of western Sichuan, China

Following field-based research and testing of residential buildings in Tibetan areas western Sichuan, this study studied the interactions between dynamic effects geographic meteorological elements. By quantifying combined influence geographical elements on building orientation, concept total orientation-based mean temperature difference was introduced, a method for obtaining optimum orientation provided based an equation calculating average by orientation. coupled shape, approach optimizing shape designs optimal width created. We found that linear expression cannot be used to describe quantitative relationship indoor When horizontal solar radiation intensity ≤6.44 MJ/m2 d, primary consideration design coefficient. >6.44 main evaluation index, coefficient auxiliary index. Based above findings, we propose scheme major cities Sichuan.
