北京市某高校建筑围护结构对能耗影响敏感性研究

Sensitivity analysis on the impact of building envelope to energy consumption in a university in Beijing

以北京市某高校教学建筑为例,采用局部因素敏感性分析法,分析围护结构参数对建筑采暖能耗和制冷能耗的影响规律。结果显示:各围护结构参数对建筑采暖、制冷能耗影响程度的平均敏感度排序为外窗遮阳系数>外窗传热系数>外墙传热系数>屋顶传热系数。

Taking a university teaching building in Beijing as an example, the sensitivity analysis method of local factors was used to analyze the influence of envelope parameters on building heating energy consumption and cooling energy consumption. The results showed that the average sensitivity of each envelope parameter to the influence of building heating and cooling energy consumption was sorted as exterior window shading coefficient > exterior window heat transfer coefficient > exterior wall heat transfer coefficient > roof heat transfer coefficient.
