Research project BuildHEAT

BuildHEAT involved the evaluation of an air-to-air heat pump system combined with the use of PV electricity produced in a decentralised manner. In this context, the heat pump system served as a heating, air conditioning and ventilation system.


European Commission

The majority of people in Europe live in apartment buildings. These buildings have a great potential for greater energy efficiency. The BuildHEAT research project funded by the European Union set itself the goal of reducing the energy consumption of these buildings by up to 80 per cent by exploiting the existing potential for savings. The aim was to develop technologies that are faster and easier to install than conventional systems.

The DLR Institute of Networked Energy Systems participated in this four-year research project together with 17 other project partners from six countries under the leadership of the Italian Institute for Renewable Energy, EURAC. Seven million euros were made available for the project from the European “Horizon 2020” research programme.

The main task was to evaluate the air-to-air heat pump systems in combination with the use of decentrally-generated photovoltaic electricity. The heat pump system acts as a heating, cooling and ventilation system in this context and also provides hot water for domestic use. The performance and key energy figures of the heat pump system were determined using our proven test procedures. The components were optimised based on the results and management solutions are developed in cooperation with the system manufacturers.
