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 Energy therefore promotes research on energy efficient cities (EnEff:Stadt) and energy efficient heating and cooling networks (EnEff:Wärme).
With the cluster project High Tech – Low Ex, a concept for an energy-efficient further development of the Berlin Adlershof science quarter was developed from 2011 to 2013 with the aim of achieving 30 % primary energy consumption compared with “business as usual”. The project is being realised in several sub-projects until 2016.
The multifunctional use of district and local heating networks could already make a notable contribution to realising low-emission heat supplies in the short to medium term. For this purpose, the research project is investigating the technical and ecological effects of decentralised feed in using coupled simulations.
The publication of IEA ECB Annex 51 „Energy Efficient Communities" is based on the evaluation of over 20 Case Studies carried out within the 11 participating countries. The guidebook also describes the methods to derive energy and emissions inventories, energy scenarios and suited implementation strategies for energy master plans.
The EnEff:Stadt Conference took place on 14 and 15 January 2014 at the conference centre belonging to the German Federal Ministry of Economics and Energy in Berlin and, in addition to the latest project experiences, presented analyses on central themes and issues relating to BMWi’s research initiatives.
