Abstract
The domestic energy demand of buildings is responsible for one third of the world's final energy consumption. To increase the sustainability of new housing areas, the identification of innovative heat supply concepts based on renewable energy sources (RES) is required. For the new housing area “Zum Feldlager” (Kassel, Germany), various supply concepts are studied. Main objective is the development of an innovative and efficient supply concept based on RES and low temperature district heating (LTDH) for practical implementation. In the course of different studies, centralised and decentralised supply strategies are analysed. The most promising supply concept is based on a central ground source heat pump in combination with LTDH and decentralised solar thermal systems. In comparison to a reference concept the annual heating costs and the CO2-emissions are lower. This project is a cooperative activity and of the Fraunhofer IBP, Institute for decentralized Energy Technologies (IdE), Kassel University, City of Kassel and Staedtische Werke Kassel AG. The paper covers a topic from IEA DHC Annex TS1.
