DIN V 18599-1 provides an overview of the procedures for calculating the energy need, delivery energy and primary energy for heating, air-conditioning, cooling, lighting and the domestic hot water supply of buildings. The central balance equations are described. It provides the general terms which apply for all parts of the DIN V 18599 series of prestandard. The general balance calculation method is outlined together with separate information on calculations for residential buildings and non-residential buildings. The procedure for defining zones of buildings is explained. In the Annex, factors for assessing the environmental effects of the energy use (primary energy factors) are listed. DIN V 18599-1 has been approved by NA 005-56-20 GA "Gemeinschaftsarbeitsausschuss NABau/FNL/NHRS: Energetische Bewertung von Gebäuden" ("Joint Working Committee NABau/FNL/NHRS: Energy performance of buildings") and published as a prestandard.
