Vision: Establish solutions for an almost climate-neutral building stock

Buildings need plenty of energy: their demand is as high as that of transportation or industry. To efficiently reduce CO2 emissions and protect resources, several new technical solutions are needed in the area of buildings-energy technology.

The central and primary goal of the energy revolution in Germany is the drastic reduction of greenhouse gas emissions, of which the largest share is generated by energy-related carbon dioxide emissions. By 2050, Germany aims to reduce its greenhouse gas emissions by at least 80%, and if possible by 95% compared to 1990 level. Other countries have set equally ambitious targets in the reduction of the CO2 emissions.

In Germany, buildings account for roughly 40% of energy demand and for around a third of the primary energy consumed. More than four fifths of this energy demand is consumed by space and water heating. To significantly reduce climate-damaging gasses, especially CO2, a massive reduction of this demand is required.

Research in the area of building and energy technology is thus of special concern to the members of the Solar Energy Systems department. We are working closely with the Fraunhofer Institute for Solar Energy Systems, ISE.

Research

The following technical solutions are being researched by members of the “Solar Energy Systems” chair:

Image
Renewable energy systems for buildings and quarters

Evaluation and development of systems solutions for using renewable energies in buildings and quarters. The technological options range from heat pumps to solar heating and photovoltaics to cogeneration power plants, heating networks and thermal energy stores.

Image
Low-exergy systems (LowEx Systems)

The optimization of LowEx systems with special focus on heat pump systems and the availability of environmental energy sources: air, groundwater and geothermal energy, in context of urban development.


› Details

Image
Efficiency in space and water heating

Analysis of systems for preparation of hot drinking water and central-heating delivery. Using simulations and on-site monitoring, we are especially engaged in the optimization and efficiency gains of LowEx systems with heat pumps.

Vita

Professor Hans-Martin Henning is director of the Fraunhofer Institute for Solar Energy Systems ISE in Freiburg and heads the “Solar Energy Systems” chair at the Institute for Sustainable Systems Engineering (INATECH, University of Freiburg). He is a member of acatech (German Academy of Technical Sciences) and spokesperson for the Fraunhofer Energy Alliance.

In 1993, Professor Henning attained his doctorate in physics at the University of Oldenburg and has been active in several capacities at the Fraunhofer ISE in Freiburg since 1994. In 2014, he was appointed to the “Technical Energy Systems” professorship at the Karlsruhe Institute for Technology (KIT). In 2017, he became head of the Fraunhofer ISE and since then has headed the “Solar Energy Systems” chair at the Institute for Sustainable Systems Engineering.

Professor Henning’s areas of focus are building and energy technology and energy-system analysis.

He plays a leading role in the development of calculation models for holistic simulation and optimization of complex energy systems, and, building on those studies, research into the development of national and regional energy systems that involves all energy sources and consumption sectors.
