Vision: Establish solutions for a climate-neutral building stock

Buildings need plenty of energy, most of which is currently provided by fossil fuels. To efficiently reduce CO₂ emissions and protect resources, new technical solutions in the field of building energy technology are needed.

The central goal of the energy transition in Germany is the drastic reduction of greenhouse gas emissions, of which the largest share are energy-related carbon dioxide missions. Germany aims to achieve climate neutrality by 2045. Other countries have set equally ambitious targets in the reduction of their CO₂ emissions.

In Germany, buildings account for roughly 40 % of energy demand and for around one third of primary energy demand, while most of this energy demand is consumed by space and water heating. To significantly reduce the climate-damaging gases, especially CO₂, a massive reduction of this energy is required. Furthermore, a steadily increasing share of renewable energies is necessary to cover the remaining demand.

Research in the area of building and energy technology is therefore a special concern to the members of the chair “Solar Energy Systems”. In addition to the development of technical solutions for the use of renewable energies for the provision of heat and electricity, this includes the optimization of renovation schedules for buildings that are in line with climate protection goals. The research group collaborates closely with the Fraunhofer Institute for Solar Energy Systems ISE.
