    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...

    “Solar thermal energy is becoming an integral part of district heating”

    Traditional district heating is converging with solar thermal energy: researchers and engineers presented new technologies for integrating solar thermal systems into the heating provision at the German Federal Ministry for Economic Affairs and Energy's status workshop entitled “Solar thermal energy in district heating”, which was held at the end of September in Dresden. In addition, the workshop also provided insights into current developments in Europe and worldwide.  more...

    Large-scale solar thermal systems in long-term testing

    Can solar thermal plants achieve a consistently high yield for more than ten years? In order to answer these and other questions, scientists from Düsseldorf University of Applied Sciences have surveyed the operators of 76 large-scale solar thermal plants and monitored ten of these systems for one year. All systems were funded at the turn of the millennium as part of the Solarthermie2000(plus) programme.  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...

    Pentagonal mirror reflects the sun precisely

    In solar tower power plants, multiple mirrors – called heliostats – direct the sunlight to the receiver at the top of the tower. Heliostats have previously had a rectangular shape. However, engineers have now developed a pentagonal concentrator mirror. They are combining this with a low-cost linear drive and new control software. Five of these heliostats are now being mounted and tested on test platforms at Jülich.

    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...

    Solar process heat

    Around three-quarters of the final energy consumption in the industrial sector in Germany is caused by process and space heating. Solar heat can be used in many different ways in the low-temperature operations in particular, as well as in the commercial, trade and services sectors. International studies confirm the global potential for this technology.  more...

    Web portal for energy-optimised buildings and districts

    The website of the ENERGIEWENDEBAUEN research initiative is now online. The German Federal Ministry for Economic Affairs and Energy is bundling its long-standing subsidy measures entitled Energy Optimized Building, Energy-Efficient City and Energy-Efficient Heating and Cooling Networks, and also research on thermal energy storage and low-temperature solar thermal energy systems in the redesigned research initiative. They are being brought together under one umbrella initiative.  more...

    40 years of energy research

    Last week, on 2nd May 2017, the German Federal Minister for Economic Affairs, Brigitte Zypries, opened the celebration for the anniversary of “40 years of energy research programmes in the German Federal Government” in the historic conference rooms of the German Federal Ministry for Economic Affairs and Energy in Berlin. She emphasised that research and development are important components in the large modernisation and investment project for energy transformation in Germany.

    The future of power plants

    The "Flexible Energy Conversion" research network was founded in Berlin at the end of February 2017. Here, researchers and developers from the conventional power plant technology and solar thermal power plant fields will jointly develop future strategies. The goals: To increase the flexibility of large-scale power plants, develop new large-scale storage systems, extensively research the use of hydrogen in power plant processes and in particular optimise the economic efficiency of solar power plants.  more...
