Nutzenergiebedarf für das Heizen und Kühlen einer Gebäudezone – Bilanzierung nach DIN V18599 Teil 2

Determination of the energy demand for heating and cooling of building zones. Balance calculation method according to DIN V 18599‐2. The balance calculation method of German standard DIN V18599 is using the well known and proven monthly balance calculation methods for the evaluation of the energy use for space heating. The method enables – supplemented with the energy demand for cooling, air‐conditioning and lighting – a consistently energy evaluation of a building. The method uses an integrative approach and takes the interaction of all participating crafts into consideration. Because of this integrative approach, the following boundary conditions are included in the balance calculation method: –·summer period (variable), –·variable heating period, –·division in periods of usage / no usage, –·cooling demand, –·air conditioning of supply air, –·lighting, –·variable solar protection devices, –·usage‐dependent internal sources, room conditions and air change rates. This method is consistent with the EU‐directive on the “Energy Performance Of Buildings” (EPBD) and complies the requirements of future regulations.
