Abstract:	In dem folgenden Bericht wird ein Forschungsvorhaben vorgestellt, welches das Ziel verfolgte, ein System zu entwickeln, mit dessen Hilfe die solare Strahlung auf Klinkerfassaden für Heizzwecke nutzbar gemacht werden kann. Das System wurde an klein- und großformatigen Versuchsaufbauten unter realen Wetterbedingungen getestet. Neben der messtechnischen Bestimmung des Entzugspotenziales wurden weiterhin die für die technische Umsetzung wichtigen Fragestellungen bearbeitet. Ein besonderer Fokus lag bei der Entwicklung von praxistauglichen Einbaumethoden unter Verwendung von etablierten und genormten Bauprodukten. Für die gewählte Versuchsanordnung konnte an sonnigen Wintertagen ein Energieangebot von ca. 0,4 kWh/m2 Fassade und Tag gemessen werden. In den Sommermonaten erhöhte sich das Energieangebot auf ca. 2,6 kWh/(m2·d). Nach ersten Erkenntnissen scheint die Nutzung dieser Energie mithilfe von Wärmepumpen technisch möglich. “Energieklinker” - A system to utilize the solar heat radiation on clinker façades. The featured research project was aiming to develop and test a specially modified clinker façade which would convert solar irradiation on the façade into energy suitable for heating purposes. The system was tested in medium and large scale experimental setups under real weather conditions. The main objective was to measure the energy extraction potential but also all other issues regarding the technical feasibility had to be taken into account. A very strong focus was laid on a practicable installation method using established and standardized construction products. For a sunny winter day an energy extraction potential of 0.4 kWh/m2 of façade and day was measured. During summer days, an extraction potential of up to 2.6 kWh/(m2·d) could be observed. Initial findings allow the assumption that this energy could be utilized by applying a heat pump.
