    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...
     

    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.

    "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...
     

    Cheaper production of solar cells

    There is intense competition in the market for photovoltaic systems. With constantly new innovations, the manufacturers are reducing their production costs and are increasing the efficiency of the cells and modules. For this purpose they are improving the production processes along the chain from silicon to the module. Companies and research facilities are working together to produce high-quality silicon crystals and wafers that save as much material as possible. They are also improving the material quality using an innovative solidification process for quasi-monocrystalline silicon. And with a new separation process they are producing more wafers from the same amount of silicon.  more...

    Learning and working in an energy-plus school

    Uhland School in Stuttgart, which dates back to the 1950s, no longer accorded with today's structural and energetic standards. The renovation work is now almost complete and the City of Stuttgart is getting its first energy-plus school. A photovoltaic system on the roof and façade of the building covers the electricity requirement.  more...
     

    Record: solar cell reaches efficiency of 22 per cent

    Recently, photovoltaic researchers presented the interim results of their project HELENE. The researchers achieved a new efficiency record of 22 per cent for industrial monocrystalline PERC solar cells (Passivated Emitter and Rear Cell). In doing so, they surpassed their previous record of 21.7 per cent, set in July 2015. The newly developed solar module technology is soon to be transferred into industrial production. The target is to generate photovoltaic power at lower costs through higher efficiencies and lower production costs.  more...
     

    Heating buildings via their exterior walls

    Surface heating systems facilitate the integration of renewable energy sources and reduce energy costs. However, since the retrofitting of underfloor heating is very expensive, thermally activated walls provide an option in existing buildings. For the first time scientists at Saarland University are testing the use of capillary tube mats in exterior wall heating.  more...

    Net Zero Energy and Net Energy Plus Buildings

    Buildings generally have the potential and infrastructure to generate the energy required by them on site. This provides the principle behind net zero-energy or net energy-plus buildings, whose numbers are steadily increasing around the world and especially in Germany. They have names like “energy-plus house”, “zero emissions house”, “efficiency house plus”, “activated-plus house” or “solar active house” and, internationally, “net zero-energy building”, “carbon neutral home”, “EQuilibrium™ House” and “Bâtiment à énergie positive”.  more...
