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).
Wüstenrot is set to become energy-independent by 2020: scenarios for the development of renewable energies are being calculated, strategies for economically utilising this potential are being developed and measures for increasing the energy efficiency of the existing building stock are being investigated. An energy-plus housing estate is being implemented as a model, which will have cold local heating provided via an agrothermal power plant.
As part of a nationwide field test, approx. 15 absorption cooling systems with a total capacity of 1.25 MW were installed for a wide range of applications and tested in operation. These systems are based on absorption chillers with nominal cooling capacities of 50 kW or 160 kW.
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.
