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).
Berlin’s largest business, science and media centre is growing rapidly. The intention is to save 30% of the primary energy by 2020 by developing an innovative energy concept, improving and linking buildings and systems in energy terms, utilising waste heat and open heating networks as well as using intelligent electricity networks and renewable energies.
In order to optimise the district heating supply in Ulm in exergetic terms when converting the steam network to hot water operation, the effects of reducing the return temperature were examined. This changes, for example, the technical requirements for space and hot water heating systems.
Fraunhofer IBP has developed a computer software to support actors in the field of urban planning during the first stages of planning energy-efficient district concepts. The very heart of the software is a tool for the energy assessment of districts, which uses archetypes and other pre-set configurations to allow for a simple and quick data input mapping all the buildings in the district.
The EnEff:Stadt Conference will take place on 14 and 15 January 2014 at the conference centre belonging to the German Federal Ministry of Economics and Technology (BMWi) in Berlin and, in addition to the latest project experiences, it will present analyses on central themes and issues relating to BMWi’s research initiatives.
