    Test methods for practical key system figures relating to energy efficiency

    Measurements on real heat generator plants show that efficiency parameters as determined by calculation sometimes deviate considerably from the values registered by measurement technology. This is especially true for heat pumps and micro CHP plants. The annual performance factor is decisive in terms of their economic success.  more...
     

    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...
     

    Smart Green Tower becomes an energy producer

    The Smart Green Tower is being built in the city of Freiburg. The 51-metre-high building will provide living, residential and working space. Depending on the solar radiation, a building envelope made of photovoltaic modules generates more energy via the photovoltaic system than can be consumed directly. In order to utilise the surplus electricity, the designers are using a flexible internal energy storage system with lithium-ion batteries.  more...
     

    Solar Decathlon competitions compact

    The Solar Decathlon student competition challenges the participating teams to develop completely solar-powered houses. More than 250 buildings have already been built in the 13 competitions that have taken place to date. A considerable amount of investigative spirit has gone into designing all of them, they are comparable and well documented. A freely accessible online database now provides a comprehensive overview and the framework for systematically evaluating the innovations and results.  more...

    Solar thermal energy reduces surface area of geothermal heat collectors

    For heat pumps with geothermal heat collectors, unglazed solar collectors offer several advantages as a secondary heat source. The surface area requirement for laying geothermal heat collectors is reduced by up to 50 percent without resulting in depletion of the ground or critical freezing conditions. Researchers at the Institute for Solar Energy Research (ISFH) in Emmerthal closely investigated this together with partners in a research project. The simulation model developed is available for simulation software TRNSYS, information materials for simplified designing rules for planners will be published shortly.  more...
     

    Heat storage system with segmental design demonstrates its qualities

    In the “OBSERW” research project researchers have developed an innovative above-ground storage tank built using a cost-saving segmental construction method. This required a complete overhaul of conventional storage constructions and building technology. Numerous technical issues were put to rest, such as the temperature-resistant sealing of segments.  more...
     

    Multidisciplinary energy efficient production

    The closing event of the “ETA Factory” research project took place at TU Darmstadt on 11 April 2018. In the course of the project, a multidisciplinary research group was able to demonstrate the feasibility of energy savings of up to 40 percent in industrial production. The jointly planned research factory saw researchers optimise and network energy flows in production and within the building.  more...

    Double heats better

    Air-to-water heat pumps are providing increasingly more heat for new or refurbished single-family homes with low energy requirements. Compared with ground source heat pumps, they have significantly lower acquisition costs and can be easily integrated into low-temperature heating circuits. Scientists from research and industry want to increase the efficiency of the systems by, on the one hand, using a second heat source for the heat pump and, on the other hand, by reducing the heat demand by means of centrally controlled individual room and supply control systems.  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...
