07. Dec 2015 - 10th Project Manager Meeting EnEff:Stadt in Lüneburg

The Project Manager Meeting on 10/11 November 2015 was used for sharing information and the presentation of new projects and analyses of the accompanying research. In particular, the workshops provided an attractive setting for a topic-focussed discussion on current issues and project experiences. The venue was the Leuphana University Lüneburg, which is aiming to achieve a climate-neutral campus by 2020.

17. Nov 2015 - Hygienically safe and energy-efficient provision of drinking water

When heating domestic hot water, a 5 degree reduction in the mean temperature can reduce heat losses by up to 13 per cent. However, sterility must be ensured and the formation of legionella must be excluded. A research project led by Dresden University of Technology wants to verify this with extensive measurements and sampling.

13. Nov 2015 - Energy transition business model – 4th EnEff:Stadt Practice Workshop in Oberhausen

On 21/22 October 2015, the EnEff:Stadt research support initiative explored the “energy transition business model” in regard to the development of energy-efficient districts. Which benefits can be derived from the district approach? Which actors will decisively shape the transformation process? In addition to researchers, representatives from local authorities, public utilities, energy cooperatives and consulting companies were also invited.

02. Nov 2015 - Quick and cost-effective laying of district heating pipes

cIn the middle of October, the AGFW energy efficiency association and the energy supplier Mainova began operating a test route in Frankfurt with the aim of testing the laying of district heating pipes in liquid soil. The process promises shorter construction times, lower costs and a reduced burden on residents and motorists.

18. Jun 2015 - Feeding solar thermal energy into district heating networks

The multifunctional use of district heating networks could already provide an important step towards achieving low-emission heating supplies in the medium term. In a research project, AGFW, Solites and the Technical University of Dresden have investigated the technical impacts caused by the decentralised provision of solar thermal heat. Several integration options are currently being tested in the district heating network belonging to the Stadtwerke Düsseldorf municipal utility company.
