标准摘要
[中文适用范围]： 本文件定义了建筑物和建筑构件热性能中使用的物理量，并给出了相应的符号和单位。 注：由于本文件的范围仅限于建筑环境中的热性能和能源使用，因此其中包含的一些定义与 ISO 80000-5 中给出的定义不同。 [外文原描述]： ISO 7345:2018 defines physical quantities used in the thermal performance of buildings and building elements, and gives the corresponding symbols and units. NOTE Because the scope of this document is restricted to thermal performance and energy use in the built environment, some of the definitions it contains differ from those given ISO 80000-5.
