标准范围

ISO 13370:2007提供了计算与地面热接触的建筑构件（包括地面楼板、悬浮楼板和地下室）传热系数和热流率的方法。它适用于位于所处建筑围墙中水平面以下的建筑构件或其部分对于地面楼板、悬浮地板和未加热的地下室，在内部地板表面的水平面上；对于加热地下室，在外部地面的水平。ISO 13370:2007包括传热的稳态部分（年平均热流率）和由于温度的年度周期性变化（热流率关于年平均值的季节性变化）的计算。这些季节性变化是按月获得的，除了适用于附录D中的动态模拟程序外，ISO 13370:2007不适用于较短的时间段。

ISO 13370:2007 provides methods of calculation of heat transfer coefficients and heat flow rates for building elements in thermal contact with the ground, including slab-on-ground floors, suspended floors and basements. It applies to building elements, or parts of them, below a horizontal plane in the bounding walls of the building situated

• for slab-on-ground floors, suspended floors and unheated basements, at the level of the inside floor surface;
• for heated basements, at the level of the external ground surface.

ISO 13370:2007 includes calculation of the steady-state part of the heat transfer (the annual average rate of heat flow) and the part due to annual periodic variations in temperature (the seasonal variations of the heat flow rate about the annual average). These seasonal variations are obtained on a monthly basis and, except for the application to dynamic simulation programmes in Annex D, ISO 13370:2007 does not apply to shorter periods of time.
