Research project

Initiative towards market establishment and dissemination of systems for supplying thermal and eletrical energy using PVT collectors and heat pumps in the building sector

Brief description:

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

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

Important marketing elements are target-group-specific information shared via booklets, internet, videos, social media campaigns, a Wikipedia record about PVT building energy supply systems as well as PR activities such as the presentation of demo buildings and an online presentation of measurement results from investigated systems. A key marketing measure: Practical planning and design tools shall be created to enable a simplified dimensioning and assessment of these complex systems and thus accelerate their market presence.

The developed tools are validated based on the results of the demonstration systems and via associated simulations of selected demonstration buildings.
