The Center for Applied Energy Research (CAE) in Würzburg and other project participants are currently developing a system called "RENbuild" for the combined regenerative supply of buildings with fresh air, cooling and electricity. The RENbuild system consists of hybrid collectors, a high-performance heat/cold storage tank, a heat pump system and a building automation system.
According to the CAE, the RENbuild system offers several advantages. For example, the heat pump can heat and cool. The latent heat storage tanks used, which have around three times the storage capacity of conventional water storage tanks, offer the possibility of intermediate storage of heat and cold. The system can also be operated in an energy-saving manner thanks to building automation.
The RENbuild system is already being tested in a residential building, a show home in Estenfeld near Würzburg. An office building with the system is due to go into operation this summer. Corresponding measurements will then also be carried out on both buildings. The research project is being funded with around three million euros.
