    Passive House primary school in Halle undergoes monitoring

    The ecclesiastical funding body wanted to use ecological building materials for the construction of a new primary school and, with the energy-optimised building, ensure a high degree of learning comfort with manageable operating costs. This resulted in the first Passive House school building to be constructed using a timber frame structure in Saxony- Anhalt. Multi-year monitoring and accompanying sociological research have verified both its energy efficiency and acceptance.  more...

    Refurbished vocational college achieves energy-plus level

    Since its refurbishment, the vocational college in Detmold generates more primary energy than it consumes. For this purpose, the facades and the top storeys have been insulated with cellulose, passive house windows have been installed and the roof areas have been covered with PV panels. The existing heating system continues to be used with reduced temperatures. Since 2016, there has been a comprehensive monitoring of its operation.  more...
     

    New Energy Research Programme published

    The German cabinet has passed the new, 7th “Innovations for Energy Transition” Energy Research Programme. The programme replaces its predecessor from 2011. Content-wise, the programme builds on the successes of recent years, sets new courses and defines focal points for research funding and innovation policy in the energy sector. For the years 2018-2022, the German Government is budgeting 6.4 billion euros for energy research.  more...

    New knowledge portal for solar heating networks

    Large-scale solar thermal systems are being increasingly used in heating networks. The Steinbeis Research Institute Solites in collaboration with international partner organisations has created a newly designed information service on solar-supported heating networks at www.solare-waermenetze.de. At the heart of the web platform is a database that provides comprehensive technical and economic expert knowledge.  more...
     

    CIGS thin-film modules beautify house walls

    In order to achieve the goal of meeting Germany's energy demand almost completely with renewables by 2050, it is planned that facades and partially shaded surfaces should also be used for generating electricity by photovoltaic means. The modules that can be used for building-integrated photovoltaics (BIPV) have to meet considerable requirements in terms of their appearance, performance and costs. Experts have summarised this need for action in their recommendations for the German federal government's 7th Energy Research Programme.  more...

    Which heat sources are optimal for heat pumps?

    The number of buildings heated by heat pumps continues to rise. In recent years, air-water heat pumps have been the dominant force in this regard. More energy efficient alternatives exist, however, to outside air as a heat source. Examples include geothermal energy, ground water, exhaust air and solar thermal energy. The variety of potential heat sources and of heat exchangers tapping these presents an incredible challenge for planners. Validated concepts, objective decisionmaking guidance and analyses are consequently called for. This endeavour is supported by two research groups.  more...
     

    Photovoltaic elements for facades and flexible roofs

    Modern building facades can do more than provide insulation and outer envelopes for buildings. New photovoltaic modules give designers considerable scope when designing the colour of facade surfaces. Unlike standard solutions, such energy facades make a considerable contribution to improving the energy balance of buildings. Standard silicon, thin-film and organic PV elements can be used.  more...
     

    Solar water heater for ceramic granules

    The innovative CentRec radiation receiver has passed its first practical test at very high temperatures in the DLR’s solar tower in Jülich. The receiver uses ceramic particles as a heat storage medium. These are inexpensive, enable very high temperatures and can be handled with relatively little effort. The practical test at very high temperatures is an important step on the way to marketing this receiver technology.  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...
     

    Heat supply – solar-active and grid-connected

    Since autumn 2016, a new passive house residential neighbourhood has been under construction at the science and technology site Berlin Adlershof. It is connected to the return feed of an existing district heating network and feeds in the solar heat generated inside the district. The project is the subject of extensive research.  more...
