    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...

    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...

    Profitability of energyoptimised buildings

    “Does that really pay off?” – this is something you often hear when people are talking about energyoptimised new buildings or refurbishment projects. Germany’s Energy Saving Act also formulates a requirement for cost-effectiveness. It is not easy to answer this question. For this reason, the terms ‘economic viability’ and ‘economically advantageous’ will first be defined.  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...

    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...
     

    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...
