摘　　要：以天津市某居住建筑为例,研究标准算法、软件模拟、温频法3种算法之间建筑耗热量的差异性。该差异性主要由透窗太阳辐射得热量的计算结果不同导致,边界条件不同是产生透窗太阳辐射得热量差异的主要原因。对边界条件进行修正,可以有效降低各算法间的差异。Taking a residential building in Tian- jin City for example, the difference among three calcu- lation methods including standard method, software simulation and BIN method for building heat consump- tion is researched. The difference is mainly caused by different calculation results of solar radiation heat gain through the windows, and the different boundary condi- tions are the main reasons for the difference in solar ra- diation heat gain through windows. Correcting bounda- ry conditions can effectively reduce the difference a- mong various calculation methods.
