Fuel cell generates electricity and heat for homes

Highly efficient, low-emission and quiet: as small-scale combined-heat-and-power stations, new fuel cell heating units produce heat energy and electrical energy with an efficiency of over 90 per cent. They have proven themselves in extensive tests in single and two-family homes, and their operation and design have been improved incrementally. The first units are now on the market. They run on natural gas, and on hydrogen and methane produced using renewable energy or biomass. Decentralised fuel cells can generate demand-oriented electricity, and they can be used in a grid-friendly or grid-independent way.  more...

Assessing solar houses in energy and economic terms

With the German Energy Savings Ordinance 2016, the maximum value allowed for the annual primary energy requirement for new residential buildings has been reduced by a quarter. This is not a problem in solar houses: they require a maximum of 15 kWh/(m2p.a.) of primary energy for heating energy and auxiliary power and are therefore well below the requirements of passive houses. The cost of this good CO2 balance can be determined using a newly developed simulation method.  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...

Schools plug into the sun

Photovoltaic systems in schools help save energy and enhance classroom teaching. They shape a school's image and indicate that energy supply is a future-focused subject. Grants are available to schools wanting to install photovoltaic panels.  more...

Schoolchildren are saving energy

At many schools they already exist: schoolchildren as energy detectives, energy managers or energy teams. They track down energy leaks, take the initiative, assume responsibility and ultimately know a great deal about saving energy. Their commitment is often also financially rewarding for their school.  more...
