Researchers in building physics at the University of Weimar are investigating how they can improve the energy balance of existing buildings and urban districts and reduce CO2 emissions. Using a digital architectural model, they are also looking at the effects of temperature developments in the interior of a building. In doing so, they take into account, for example, how windows,...

Owners or tenants who do not have space for a solar system on the roof can instead equip their balcony or terrace with a so-called plug-in solar device. The energy advice service of the consumer advice center now points this out. These plug-in solar devices are approximately 1.00 x 1.70 meter modules with an output of around 300 watts. To install such a...

If owners want to renovate their façade, they can also install new doors and windows at the same time. Martin Brandis, energy expert at the consumer advice center, advises this. The reason for this is that heat can be lost through old windows, for example. According to the consumer advice center, the heat loss factor (UW value) of old windows is 3.0 or more and therefore exceeds the legal...

Putting on a sweater, wrapping up in a blanket and heating less - two thirds of Germans would be prepared to do this in winter to make Germany more independent of energy supplies from Russia. This is the result of a survey conducted by the forsa opinion research institute on behalf of the Deutsche Bundesstiftung Umwelt (DBU) for the DBU environmental monitor "Energiewende und...

Hajo Schörle from W&D Schörle has given some thought to how the next generation can be involved in energy consulting. The result is the book "There's a lot of energy in it". On 40 pages, children learn more about the topic - from energy-efficient refurbishment to storing energy and generating their own energy. The book...

Companies that have developed innovative and sustainable technologies for the renovation of existing buildings can still apply for the "German Renovation Award".
