IntegraTE

At first, the relevant parameters to describe and assess this technology or related systems were defined, collected, and shared through comprehensive, target-group-specific marketing. The available system concepts on the market were classified; selected systems were investigated through measurements. For the energetic, economic, and ecological assessment of the systems, appropriate parameters were defined.

To create a basis for the further dissemination of PVT building energy supply systems, comprehensive, target-group-specific marketing addressed stakeholders from the entire value chain — e.g., manufacturers of systems and system components, planners, architects, plumbers, as well as end customers. In this process, there was intensive cooperation with relevant associations such as the Bundesverband Wärmepumpe (BWP, Federation for Heat Pumps), the Bundesverband der Deutschen Heizungsindustrie (BDH, Federation of the German Heating Industry), and the Bundesverband Solarwirtschaft (BSW, German Solar Industry Association).

Important marketing elements included target-group-specific information shared via booklets, websites, videos, social media campaigns, a Wikipedia entry about PVT building energy supply systems, and PR activities such as the presentation of demonstration buildings and an online presentation of measurement results from the investigated systems. A key marketing measure: practical planning and design tools were developed to enable simplified dimensioning and assessment of these complex systems, thereby accelerating their market presence.

The developed tools were validated based on the results of the demonstration systems and through simulations of selected demonstration buildings.
