    "We have to increase our efforts!"

    The first ENERGIEWENDEBAUEN conference took place in Berlin from 30 - 31 January, 2017. Some 350 participants from research, academia, architecture and planning offices, politics, energy suppliers, cities and municipalities as well as the real estate industry discussed how the energy supply of buildings and districts could be made future-proof. The aim of the German federal government is to create a climate-neutral building stock by 2050. This will not be easy to achieve.  more...
     

    Fresh air without mechanical ventilation

    Ventilating non-residential buildings naturally but in a controlled manner saves primary energy and requires lower investment and operating costs than mechanical ventilation systems. Scientists from Stuttgart University have therefore developed a ventilation concept that ensures a good indoor environment and reduces the electricity consumption for operating the ventilation system.  more...
     

    Fun in a passive house pool

    The monitoring shows that the thermal heat and electricity consumption can be reduced even further during ongoing operation if the building is well-regulated, optimised and continually monitored. The public swimming pool complex in Bamberg consumes over 50 per cent less heat than comparable leisure pool facilities. A thermally high-quality building envelope allows indoor air humidities of up to 64 per cent. This reduces the pool water's evaporation rate and the necessary air change rate for providing dehumidification. This therefore also reduces the electricity and heating requirements.  more...

    New lighting strategies for streets, footpaths and squares

    LED is the future of street lighting. The LED Walkway on the grounds of Berlin’s Technology Museum, which opened in March 2015, demonstrates potential applications. The lighting technology developed allows the lighting level and light conditions to be adapted to external factors such as weather conditions and traffic volume. Spaces can now be set to a defined brightness with minimum stray light. The “StEffi Street Lighting” research project, launched in May, aims to develop and evaluate concepts for space-specific lighting and increase the potential savings with LED technology.  more...
     

    Storing heat until winter

    To be able to use summer heat for heating during the winter, hot water storage systems have to be very large. Small storage systems cool down too quickly. With this in mind, seasonal storage tanks have been developed almost exclusively for housing estates or very large consumers. Now researchers have created a new long-term storage system which is also suitable for single-family homes.  more...
     

    The building serves as a heat storage tank

    Buildings with high solar shares of fraction require large water tanks to store heat. Researchers have developed a space-saving alternative: excess heat is stored in the ceilings of the building via building element activation. Scientists are currently testing the concept in an experimental building near Hanover. They now have the results of the first year of operation.  more...
     

    Efficiently heating & cooling non-residential buildings

    The use of environmental energy to cool or, in combination with heat pumps, to heat non-residential buildings via thermo-active building systems (TABS) has established itself in recent years. The objective of such building and system concepts is not only to consume as little energy as possible in quantitative terms (low energy), but also to achieve the most optimal energy conversion in thermodynamic terms that takes the quality of the energy used into account (low exergy, „LowEx“).  more...
     

    Energy-efficient use of university buildings

    Using the Ludwig Maximilian University of Munich as an example, researchers want to show how efficiency improvements can pave the way for a climate-neutral university campus. In the project HoEff-CIM, the buildings are reproduced and evaluated in a model with the aim of developing appropriate refurbishment strategies and an energy management system for building operation.  more...
     

    Keeping a cool head in the summer heat

    Many present-day office and administrative buildings are not air conditioned. When the temperatures rise during the summer, this can have a negative effect on the thermal comfort of the users. Scientists analysed what effect improved protection against the sun and the use of ceiling fans can have on user behaviour and satisfaction. So-called comfort models are also important influencing factors.  more...

    Guidelines for energy-efficient data centres

    In Germany alone, data centres annually consume around 10,000 GWh of electrical energy – with an upward trend worldwide. In the RenewIT European research project, scientists from Spain, the Netherlands, Italy, the UK and Germany are investigating how data centres can be almost completely powered by renewable energy. The preliminary results are now available. BINE Information Service spoke with Dr Thorsten Urbaneck, private lecturer at Chemnitz University of Technology, and the project manager of the German part of the collaboration.  more...
