    Neckarpark Stuttgart: Heat from waste water

    Sewage stinks and is filthy – but it is suitable for supplying heating and cooling to buildings. In Stuttgart’s new Neckarpark urban district, the energy in the municipal waste water is extracted by means of a trough heat exchanger in the sewage channel and utilised via a low-temperature local heating network. This provides the basis of the energy concept for the new district, which is being created with highly energy-efficient buildings on the brownfield site belonging to the former Bad Cannstatt railway freight depot.  more...

    Future heating supply designed

    Over the past thirty years, the population of Duisburg has fallen by more than a fifth, and the heating requirement has also reduced. A team of experts has investigated how the municipal utility company can adapt the heating supply in accordance with these developments by 2050. A main recommendation: The interconnection of two district heating networks would increase the primary energy efficiency and cut costs, mainly because industrial waste heat could be better utilised.

    Efficiently using district heat

    In future, it is intended that heating and domestic hot water systems in district heating networks should be increasingly capable of functioning with environmental heat at lower temperatures. However, at the moment the cooling potential is not yet being satisfactorily utilised. This is generally resulting in return temperatures and volume flow rates that are too high. This provides the starting point for the LowEx Systems project.  more...
     

    Energy centre supplies Giessen University Hospital

    Giessen’s municipal utility company and University Hospital have jointly constructed the first energy centre to be integrated into a local heating and cooling network. The newly developed combined cooling, heating and power system ensures an uninterrupted supply to the hospital. It saves 21.7 % of the primary energy and 33.6 % of the CO2 emissions.  more...

    University campus to become climate neutral

    An interdisciplinary research team has developed an energy master plan for the campus belonging to the Technische Universität Braunschweig. Various scenarios for developing the campus as far as 2020 have been created with the aim of reducing the primary energy consumption by 40% and, in the long term, facilitating the conversion to renewable energy. Planning principles have been developed for the renovation and urban development of the site that can also be transferred to other urban districts.  more...
     

    Standardised feed in of solar heat

    Solar thermal systems are very suitable for retrofitting into existing buildings. However, a lack of standardisation exists when coupling the system to a district heating network. Viessmann and the Technical University of Dresden are therefore developing suggestions for future standardisation. This should help to reduce the planning effort required and save costs through unification of the various circuit variants.  more...

    Local heating links new-build with existing district

    By means of a district energy concept, researchers in Ludwigsburg are combining the advantages of ambitious building concepts and refurbishment measures with energy efficient heat supply. The heat required for the Sonnenberg development area is generated in winter using a brine/water heat pump in combination with a combined heat and power plant. The local heating network and its extension into the adjacent existing district of Grünbühl provide the post-war housing estate, which is in need of refurbishment, with not just greater living comfort but also energy efficiency benefits and cost savings.  more...
     

    Gas and heating networks act as energy storage systems

    Heating and gas networks can balance out fluctuations in the electricity grid. But how flexibly can surplus electricity be indirectly stored? In the Multi-Grid Storage project, scientists have investigated how it can be best of all stored in the form of heat or gas and then made available again as electrical energy as soon as it is required.  more...
     

    Making district heating renewable

    Three research teams have investigated how the proportion of renewable energies can be increased in district heating networks. Custom strategies were developed in this respect for the model regions Jena and Ulm. The key lay in identifying the appropriate renewable energy sources and in understanding the potential these exhibit and the effect their inclusion would have on the efficiency of the networks. The project also comprises a survey of existing heat networks with best practice analyses.  more...
     

    Research funding for the energy turnaround increasing

    Energy research contributes towards the development of the processes and technologies necessary for achieving the goals of the energy turnaround. The German government has been continuously increasing funding for energy research since 2006. In 2013 alone, it spent 100 million euros more on this than in the prior year. This reinforced above all the research areas of energy efficiency and renewable energy sources. It provided just under 300 million euros for each of these subjects.  more...
