Climate protection gain in importance, both socially and politically, in recent years. In the building sector, the EU Energy Performance of Buildings Directive (EPBD) 2010/31/EU introduced nearly zero-energy buildings (nZEB) with very high energy performance and a nearly zero or very low amount of energy required, which should be covered by energy from renewable sources as standard for all new buildings by 2021. The combination of solar and heat pump systems is a promising concept for the energy supply of buildings with high amounts of renewable energies in compliance with the EPBD. Furthermore, innovative technologies such as hybrid photovoltaic-thermal collectors support the possibility of linking heat and electricity systems in the energy generation as well as the energy consumption of a building. Due to the volatility of renewable energies, the decentralized thermal and electrical storage capacity of a building gains also in great significance.

The focus of the research project SolWPHybrid is the systematic analysis of solar and heat pump systems as hybrid systems for the heat and electricity supply of buildings by combining PVT and heat pumps with thermal and electrical energy storages.
