The objective of the measure is to implement an integrated energy concept in a public infrastructure including lighting, cooling, ventilation and heat supply. By feeding in excess heat of approximately 4.200 MWh/a, as a result, the 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 chillers (KKM) are replaced by the AKM and a small KKM, which also serves the emergency supply and is also 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. The heat supply is secured by the connection to the district heating network of the BTB.
