The aim of the project is to achieve increased market penetration with technically and economically attractive systems for thermal and electrical energy supply using PVT and heat pumps in the building sector. For this purpose, the essential characteristics to describe and assess the technology as well as the corresponding systems are defined, collected and disseminated by means of extensive target-group-specific marketing measures. As a basis, the system concepts available on the market are classified and selected systems are investigated by means of in-situ measurements. For the energetic, economic and ecological evaluation of the system corresponding evaluation key figures are defined. For a further dissemination of PVT building energy supply systems, extensive target group-specific marketing measures are carried out. These address players from the entire value chain, such as manufacturers of systems and system components, planners, architects and installers as well as end customers. The marketing activities involve intensive cooperation with the relevant associations, such as the BWP (Bundesverband Wärmepumpe / German Heating Association), the BDH (Bundesverband der deutschen Heizungsindustrie / Federation of German Heating Industry) and the BSW (Bundesverband Solarwirtschaft / German Solar Association). Important marketing elements are the creation and distribution of target group-specific information materials such as brochures, websites, videos, social media campaigns, the creation of an entry in Wikipedia on the subject of PVT energy supply systems for buildings, the effective public presentation of demonstration buildings and an online presentation of the measurement results of the systems investigated. A central component of the marketing measures is also the development of practical planning and design tools, which will simplify the dimensioning and assessment of these complex installations and speed up their market penetration.
