    Grid-supportive buildings and districts

    The expansion of renewable energies requires increasingly flexible, complementary power generation as well as flexibilisation of the electricity demand from consumers. In addition to traditional electricity-to-electricity storage systems and flexible power plants, buildings can also play an important role in shifting electricity demand.  more...

    Profitability of energyoptimised buildings

    “Does that really pay off?” – this is something you often hear when people are talking about energyoptimised new buildings or refurbishment projects. Germany’s Energy Saving Act also formulates a requirement for cost-effectiveness. It is not easy to answer this question. For this reason, the terms ‘economic viability’ and ‘economically advantageous’ will first be defined.  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...

    Electromobility - What drives us now and in the future

    Highly efficient, low-noise and zero-emission: the electric powertrain offers dynamic mobility, can integrate renewable energies and makes the transport sector less dependent on crude oil as an energy source. However, which technology will dominate electric vehicles of the future: batteries or fuel cells? An either-or decision is not necessary.  more...
     

    Cooling with solar heat

    The cooling or air conditioning of buildings with solar heat has a particular appeal because the heat demand and supply are usually consistent with each another. Cold stores in southern climates and many process refrigeration systems also require considerable energy when the sun shines intensely. The use of solar cooling systems instead of electric chillers also eases the grid, particularly at peak load times.  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...

    Thermoelectrics: power from waste heat

    Waste heat is produced in all areas of daily life – in industry, homes and transport. In Germany alone, this adds up to a waste heat potential of 300 TWh per year. This energy volume corresponds to nearly half the total energy consumed by German industry. Thermoelectric generators (TEGs) can tap into this huge energy reservoir and transform the "waste energy" without moving parts into a higher form of energy.  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...

    Ventilation in schools

    In Germany, the shortened overall length of secondary education and increasingly frequent all-day teaching mean that children, adolescents and teachers these days spend more hours of the week in school buildings than previous generations. Modern school buildings need to be able to offer a diverse education and facilitate the use of schools as a learning and living environment. In addition to the socially widely discussed educational approaches, an essential aspect of state-of-the-art schools also includes the provision of buildings with a higher user quality. Given the drop in pupil numbers, this is mainly concerned with the structural and energy-efficient retrofitting of existing buildings rather than with new-buildings.  more...
     

    Sustainable refurbishment of museums

    There are more than 7,000 museums in Germany. However, many museum buildings are now in need of refurbishment and their systems technology is outdated. At the same time, the financial position of cities and municipalities has become so acute that public amenities, such as swimming pools and libraries, are being forced to close. There is therefore a move towards transforming museums into independently operated enterprises that have to bear at least part of the maintenance, upkeep and utility costs for their buildings themselves.  more...
