Computes a transparent planning estimate for space-heating demand. The method is not DIN, VDI, GEG or PHPP and must not be used as regulatory proof. It combines transmission heat loss from each envelope component, ventilation heat loss from heated volume and air changes, monthly heating degree days from the nearest DWD 1991-2020 temperature-normal station, stated internal gains and optional domestic hot water.
