Description / Abstract:

This part of ISO 15927 specifies the definition, method of calculation and method of presentation of the climatic data to be used in determining the design heat load for space heating in buildings. These include

— the winter external design air temperatures;

— the relevant wind speed and direction, where appropriate.

Heat loss through the ground, which also contributes to the heat load for buildings, depends on longer-term temperature changes; methods for calculating ground heat loss are given in ISO 133701).
