Energy Concept for the E.ON ERC Main Building

The Energy Concept of the new E.ON ERC main building is based on geothermal energy and heat displacement in connection with a heat pump process. The geothermal field has approximately 40 boreholes, each 100 m in depth. Heat and cold base loads are distributed by concrete core activation. A sorption-supported air conditioning unit will provide isothermal fresh air to conference rooms and CIP-pools. Offices will be equipped with façade ventilation units, covering peak loads with the supply of cold air during summer and hot air during winter. A gas-fired combined heat and power engine will provide high temperature heat.
