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).
The “Welheimer Mark” district in Bottrop consists of industrial and commercial areas, with an adjacent residential area. In the medium term, it is to serve as an example of an energy-efficient mixed area with an optimised and low-emission energy supply.
In a research cooperation of Fraunhofer ISE, Fraunhofer UMSICHT, RWTH Aachen and Imtech Deutschland, simulation models were developed to map complex hydraulic networks with two-substance fluids and phase change media.
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.
