EnEff:Stadt and EnEff:Wärme - Research for Energy Efficiency

In addition to the energetic optimisation of individual buildings, the aim of raising energy efficiency depends crucially on a comprehensive approach to urban areas as well as to local and district heating networks . This potential can be improved significantly via intelligent use and networking of innovative technologies with research and pilot projects. “Efficient Energy Use” plays a crucial role. The Federal Ministry of Economics and Technology (BMWi) therefore promotes research on energy efficient cities (EnEff:Stadt) and energy efficient heating and cooling networks (EnEff:Wärme).

Model city district refurbishment: Weingarten West, Freiburg

Primary energy consumption of all energy services is to be reduced by 30% in comparison to present consumption and the project is thus to represent an exemplary, future-proof model for energy-oriented city refurbishment. Furthermore, refurbishment in compliance with the passive house standard is to be demonstrated with the 16-storey high-rise building at Bugginger Strasse 50 serving as an example.

Integrated Neighbourhood Energy Concept, Karlsruhe-Rintheim

Based on a neighbourhood energy concept, a local heating network was set up to renovate the buildings for maximum economic effect.  In addition to innovations in building conceptual design and services equipment, measurement and control technology, this project will be the first to implement a low-ex approach for an entire neighbourhood.
