According to the current German Energy Savings Ordinance, new residential buildings are to require one quarter less primary energy. Solar houses with large collector surface areas meet this requirement. In these well-insulated buildings, solar energy systems cover at least 50 per cent of the heat demand. The BINE Projektinfo brochure 'Assessing solar houses in energy and economic terms' (09/2016) details the costs and energy requirements of the various solar house concepts.
Primary energy demand and costs in comparison
In order to scientifically evaluate the buildings, the scientists developed a new simulation method in the research project HeizSolar. With this new method, experts can analyse different solar house constellations in terms of primary energy demand and costs.
For example, the researchers varied the solar savings fraction between 50 and 100 per cent, and combined the data with different efficiency house standards. They also compared the solar house concept with other low-carbon heat supply concepts, such as using pellets or logs to meet heating requirements.
The foundation for the development of the simulation method was formed by evaluations of three multi-family and six single-family homes. These conceptually different solar houses were measured throughout several heating seasons. Based on the monitoring results and the gained operational experience, the scientists then derived optimisation suggestions for the collector layouts and the storage technologies.
The research project HeizSolar was carried out under the leadership of the Fraunhofer Institute for Solar Energy Systems. Participating institutes included Sonnenhaus-Institut, the Ilmenau University of Technology, and Solar- und Wärmetechnik Stuttgart.

Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
Just in time for Christmas, a Mars-analogue mission in Morocco, coordinated by the Robotics Innovation Center of the German Research Center for Artificial Intelligence (DFKI) as part of the SRC project FACILITATORS, has been successfully completed. SRC, the Strategic Research Cluster on Space Robotics Technologies, is a program of the European Union to support research and development in space technologies. From mid-November to mid-December 2018, a team of more than 30 scientists from 11 countries tested technologies for future exploration of Mars and Moon in the desert of the Maghreb state.
Close to the border with Algeria, the Erfoud region in Morocco – known to tourists for its impressive sand dunes – offered ideal conditions for the four-week...
