    Monitoring verifies energy savings

    Systems with integrated phase change materials (PCMs) offer considerable potential for heating and cooling buildings more efficiently. However, so far there has been very little practical experience that has been underpinned by reliable measurement and monitoring data. In the PCM-Demo II research project, eight partners from research and industry are investigating and assessing PCM systems in various applications in the building sector. The preliminary results are now available.  more...

    Ventilating operating theatres energy-efficiently

    How can the high energy consumption required for ventilating “clean rooms” in healthcare and industrial production be reduced while ensuring equal or even better protection against airborne particles and germs? This question was investigated by researchers from Hermann-Rietschel-Institut (HRI). They built a research laboratory with two cleanrooms. The results provide a detailed picture of the air flow processes and improved design principles for constructing and operating cleanrooms.  more...

    Modern living in an historic urban district

    The Margaretenau residential district in Regensburg is being modernised to improve its energy efficiency. The designers are developing a solar-active and -adaptive exterior render system as a replacement for conventional thermal insulation for the facades. This should increase the solar yields and improve the thermal comfort inside the buildings. The energy supply will be provided by a new and efficient hybrid heating system consisting of cogeneration and heat pump technology.  more...

    Software assesses lifecycle costs

    Building projects often specify components that are the cheapest to buy – which in the long run is not always the most cost-effective and efficient solution. Together with Dresden scientists, software provider Hottgenroth has developed a program module that helps to determine and optimise the lifecycle costs of components and system technology. It is now available as a module integrated into existing energy consulting and planning software.  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...

    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...

    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...
