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.
Research on LowEx technologies
Select concepts, methods and projects from LowEx research were introduced at the conference in Kassel. Applications of LowEx systems and concepts in buildings and settlement construction will also to be found within EnEff:Stadt pilot projects. A concise conference documentation has been published.
Premiere of Enff:Wärme at the Berliner
Energietage Conference
On the 10th of May, for the first time, the research initiative EnEff:Wärme was comprehensively presented as part of the conference Berliner Energietage 2010. Over 100 participants witnessed discussions of concepts and new perspectives for energy-efficient use of district heating and local heating.
