Energy-Optimized and Climate-Neutral Buildings

Funding is focused on the guiding principle of energy-optimized and climate-neutral buildings of the future. The main goals of research and development projects, as well as demonstration projects, are to minimize primary energy demand, to integrate renewable energy sources, and thus to drastically reduce greenhouse gas emissions. This relates to the areas of the manufacture, operation, modernization, and dismantling of buildings and building materials.

Individual buildings and building complexes, as well as interfaces with adjacent buildings and the district, are analysed in detail as part of the research into energy-optimized buildings. The integrated analysis of the building in the context of its surroundings with a view to its viable incorporation as an energy sink, source, or storage in the local energy supply system goes hand in hand with the conversion and expansion of the supply networks for electricity, heating, cooling, and water.

Research for energy-optimized buildings also places an emphasis on research and development of structural engineering and technical equipment for buildings. The research topics include further development of innovative materials and technologies, particularly those produced from renewable raw materials, and the further development of technologies for using regenerative heat. The development of building-integrated solar thermal power and photovoltaics as well as coupled photovoltaic-thermal systems also play an important role in the funding.

Systematic analysis of the life cycle, along with integrated building concepts and smart energy management systems, require an increasing degree of digitization in the construction and operation of buildings. Previously unused efficiency potential is being opened up to exploitation by interlinking components and users. Methods of holistic balancing and optimization, as well as methods of simulation and modelling, are important areas of research.

Demonstration and pilot projects transfer the insights obtained to practical situations with accompaniment from science in order to add detail to those insights. This provides additional information about the energy performance of buildings and technologies in a real environment.
