本国际标准规定了一种方法,可以方便地计算整个建筑物和建筑物局部的传导热损失系数。本标准假定加热空间处于均匀不变的温度。ＩＳＯ13789是有关建筑物和建筑单元热性能的设计和评价计算方法的系列标准之一。计算结果可用于计算年耗能、建筑物的热负荷的输入,也可表示一个建筑 This International Standard specifies a method that allows for easy calculation of the coefficient of conduction heat loss throughout a building and building. This standard assumes that the heating space at a uniform temperature. ISO 13789 is one of a series of standards for the design and evaluation of thermal performance of buildings and building units. Calculation results can be used to calculate the annual energy consumption, the heat load of the building input, but also that a building
