    Ten outstanding concepts awarded

    On 6 December 2017, ten outstanding and innovative concepts were awarded prize money totalling 280,000 euros at the German Federal Ministry for Economic Affairs and Energy in Berlin. The respective juries awarded five winners in both the “Concepts for Future-oriented Buildings and Districts” category and in the “Ideas for an International Energy Competition” category in the ideas competition held by the EnEff.Gebäude.2050 funding initiative.  more...
     

    Differentiated assessment of economic benefits

    Nowadays, it is relatively easy from an engineering viewpoint to construct buildings with extremely low energy requirements. However, is it also possible to achieve this energy level, which is ambitious in terms of planning, building technology and commercial considerations, with existing buildings on a large scale? And is this advantageous from a financial point of view? In the BINE interview, Professor Thomas Lützkendorf from the Centre for Real Estate at the Karlsruhe Institute of Technology (KIT) discusses the statutory framework conditions, calculation methods and data bases for transparently determining the economic benefits of energy-optimised buildings.  more...
     

    On-roof insulation made of cattail plants in development

    Energy-saving in the production, pressure-resistant and compostable: Researchers at the Fraunhofer Institute for Building Physics have high expectations for the insulation boards made from the leaves of the Typha plant. Together with industrial partner Saint Gobain Isover, they are now further developing a board for insulating rafters and preparing its series production.  more...

    New energy-efficient school building in the spotlight

    The new, energy-optimised building for the Willibald Gluck Secondary School in Neumarkt (Upper Palatinate, Germany) utilises solar energy and near-surface geothermal energy. The first year in regular operation has provided good values: the heat pumps are contributing their planned share to the heat generation and the photovoltaic systems cover 35 per cent of the electricity consumed for the building operation and use. Storing the PV electricity in a vanadium redox flow battery has not, however, increased the proportion of self-consumed electricity during the first year of operation. The operation of the ventilation systems also provides potential for optimisation.  more...

    Competition building becomes a university laboratory

    A team of students from Berlin University of the Arts and Technische Universität Berlin designed a net energy plus building for the Solar Decathlon Europe 2014 competition. The house is now being rebuilt on the Charlottenburg campus. It is intended for use as a seminar room and laboratory in the future. After minor modifications and with additional measurement technology, the students can learn about energy monitoring with a real building as an example.  more...

    Gas engine heat pump supplies renovated residential complex

    The energy efficient renovation of apartment buildings from the post-war years was aimed at achieving a CO2-neutral energy supply in conjunction with the use of renewable energies. The core element of the new heating system is a gas engine heat pump that uses groundwater as the heat source. This not only supplies the low-temperature space heating but simultaneously heats the domestic hot water efficiently.  more...
     

    School: Refurbished from Plattenbau to Passive House

    The school building belonging to Max Steenbeck Secondary School in Cottbus was old and the extent of the building damage made it impossible to carry out renovation work during the school's ongoing operation. This meant that the school had to move. To this end, an old system-built “Plattenbau” school with an auditorium and gymnasium had to be first of all comprehensively modernised. The City of Cottbus placed high demands in terms of the energy consumption, comfort and operating costs.  more...

    Flexible turbomachines stabilise the power grid

    In future, conventional power plants will need to become more flexible in order to compensate for the fluctuating power generation by renewables. This requires modified gas and steam turbines. These will have to work more frequently under partial load, with more start-up and shut-down cycles and function with changing fuels. AG Turbo has compiled the research and development objectives for these new framework conditions in the ECOFLEX-turbo programme.  more...
     

    Web portal for energy-optimised buildings and districts

    The website of the ENERGIEWENDEBAUEN research initiative is now online. The German Federal Ministry for Economic Affairs and Energy is bundling its long-standing subsidy measures entitled Energy Optimized Building, Energy-Efficient City and Energy-Efficient Heating and Cooling Networks, and also research on thermal energy storage and low-temperature solar thermal energy systems in the redesigned research initiative. They are being brought together under one umbrella initiative.  more...

    Servers heat office buildings

    The Züblin construction group set high standards for the extension of their headquarters: in terms of construction, energy efficiency and sustainability. In operation, the energy consumed for heating and cooling is below the calculated values. The high-performance data processing centre housed in the building provides enough thermal energy to heat the building. The thermal comfort leads to a high level of satisfaction of the occupants. Most of the energy – far more than planned – is consumed by artificial light.  more...
