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).
An integrated district energy concept is being developed for the new Sonnenberg housing estate in Ludwigsburg and the neighbouring Grünbühl estate, which is in need of refurbishment. The concept will provide the basis for implementing innovative local district heating and exemplary refurbishment projects and new-build schemes.
A new urban district with highly energy-efficient buildings is being created on a 22-hectare derelict site. The main energy source for supplying heat and cooling will be waste water, whose energy will be utilised via a low-temperature local heating network by deploying heat exchangers and cascaded heat pumps.
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.
