The objective of the measure is to implement an integrated energy concept in a public infrastructure including lighting, cooling, ventilation and heat supply. As a result, the computational final energy demand and primary energy demand are significantly reduced. The core of the energy concept is the heat recovery from the cremation process for heating and cooling purposes (absorption chiller AKM). In AKM, the natural refrigerant ammonia is used. The existing compression refrigeration machines (KKM) are replaced by the AKM and a small KKM, which also serves the emergency supply. The AKM supplies an ice storage system that ensures the cooling supply during the night hours when the AKM is not in operation. Smaller structural and technical measures (curtains in the cold rooms and monitoring) serve to reduce the need for cooling. The KKM is operated with a natural refrigerant (CO2 or propane). The planned PV plant is financed by Berliner Stadtwerke KommunalPartner GmbH and is not the subject of the BENE project.
