DIN EN ISO 52017-1:2015-03

This new international standard will, in two parts, integrate EN 15265, EN 15255, EN-ISO 13791 and EN-ISO 13792.Depending on the development, the split between part 1 and part 3 will be between a detailed method(s) (part 1) and simple method(s) (part 3).This standard will contain a consistent and integrated set of requirements and additional descriptions of the thermal balance model for the hourly calculation of the energy needs for heating and cooling, the heating and cooling loads and indoor temperature in a thermal zone of a building. It will be directly usable by ISO 52016-1 for the calculation of the energy needs and by other EPB standards (e. g. from CEN/TC 156) dealing with needs, loads or indoor (e. g. summer) temperature calculations.
