DIN V 18599-6:2016-10

DIN V 18599-6 provides a method for calculation of ventilation systems and air heating systems for residential buildings.
This document describes the energy use of ventilation systems and air heating systems for residential buildings in conjunction with individual subsystems (transmission, distribution, storage and generation). For this purpose, both the heat losses and the auxiliary energy of the individual subsystems are determined and, provided that these occur within the heated zone, are made available for the subsequent calculations described in DIN V 18599-1 and DIN V 18599-2.
It is also possible to determine the use of subsystems for heat delivery to DIN V 18599-5 and DIN V 18599-8 and vice-versa. In such cases, the initial output data are from DIN V 18599-1 and DIN V 18599-2, while the boundary conditions are obtained from DIN V 18599-10. It is also possible to calculate the energy balances of several building zones in which there are more than one unit to be balanced.
DIN V 18599-6 has been approved by NA 005-12-01 GA "Gemeinschaftsarbeitsausschuss NABau/FNL/NHRS: Energetische Bewertung von Gebäuden" ("Joint Working Committee NABau/FNL/NHRS: Energy performance of buildings") and published as a prestandard.
