Hygrothermal performance of buildings. Calculation and presentation of climatic data - Accumulated temperature differences (degree days)1 Scope This part of ISO 15927 specifies the definition, method of computation and method of presentation of data on accumulated temperature differences, used for assessing the energy used for space heating in buildings. These are normally expressed in degree hours or degree days, and such data are often referred to simply as heating degree hours or heating degree days. This part of ISO 15927 includes approximate methods for calculating accumulated
