    Developing multifunctional façade elements

    As the outermost layer of the building envelope, the façade performs numerous functions. They are to be intelligently combined to create a system that permits the application of cost-effective, multifunctional façade systems. To do this, scientists are developing a façade element with integrated organic photovoltaics, textile sun protection, a sustainable insulating material and the sensors necessary for control. The next step is to test the elements on the south façade of a multi-storey residential building.  more...

    Testing climate-neutral districts in the real-world laboratory

    How can energy efficiency measures and the utilisation of renewable energy sources enable districts to get by with virtually no fossil fuel? How can smart networking of power, heat and mobility be achieved? Scientists and other stakeholders are investigating these questions in six flagship projects. Initial results and local challenges were outlined by the research teams in a panel discussion at the Berliner Energietage conference.  more...

    Optimising heat pumps for multi-family homes

    Solutions for the application of low-exergy systems are being developed to supply heat to existing multi-family homes. This building services equipment includes electric and gas heat pumps as well as heat transfer and ventilation systems. Different system concepts are assigned to different building types and refurbishment processes and then evaluated. The aim is to realise and evaluate the developed heat pump systems and components in exemplary refurbishment projects.  more...

    From air base to residential neighbourhood

    A new residential district is being built on the site of a former air base in Oldenburg. In addition to new buildings, some of the former barracks buildings will be preserved and converted into residential buildings. A new infrastructure concept is planned that will couple the electricity, heating/cooling and electromobility sectors and integrate them into a cross-sectoral supply network. In addition, the project partners are developing a digital service platform to provide intelligent load and procurement management at the district level.  more...

    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...

    New building services concept tested in hotels

    The conversion of a residential building to a hotel in the centre of Munich focussed on comfort and energy efficiency. The building envelope almost achieves the passive house standard following the renovation. The system technology is adopting a different approach: decentralised heat pumps produce domestic hot water and space heating heat on a room-by-room basis. A twin-pipe chilled water network balances out the heat and cooling requirements between the individual rooms.  more...
     

    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...
