Using Regenerative Energy Efficiently

Besides increasing the share of renewables, efficient energy and building control systems are key to implementing the energy revolution.

The energy policy concept published by the German federal government stipulates that primary energy consumption should be reduced by 50 percent of the 2008 value by 2050. Effective 1 January 2016, the permissible primary energy consumption of new buildings must be 25 percent lower. At the same time, the primary energy factor for electricity was lowered from 2.4 to 1.8. In this context, innovative building control systems enable energy-efficient, environmentally friendly heating and cooling of buildings.

Our research and development activities focus on the following topics:

  • Systems to improve the effi ciency and environmental safety of geothermal energy using geothermal probes and heat pumps
  • Systems and processes to utilise the wastewater heat potential in sewers to supply energy-efficient buildings
  • Methods for the large-scale integration of solar collectors into the building envelope
  • Cold/heat storage systems for renewable energy sources to supply energy-efficient buildings, including systems integration
  • Dynamic simulation of buildings and systems integrating physical performance, use patterns, climate data and building control systems
  • Integrated concepts for building services with simulation-based operation including user behaviour and weather forecasts
  • Innovative district cooling/heating systems as a prerequisite for the use of efficient combined heat and power systems, geothermal energy, low-cost solar heat and waste heat from industrial processes
  • Multi-functional supply components for generating and storing energy, providing sunshading, glare protection and privacy, sound and heat insulation, daylight use and ventilation
