The Efficiency House is a key standard that defines the energy efficiency of residential buildings in comparison to a reference building. Two important key figures play a role here: the total energy requirement of the building and the quality of the thermal insulation. These criteria can be used to assess a building in concrete terms. Particularly worth mentioning is the efficiency house level 40, which...

The respective state building regulations...

With its climate protection measures to date, Germany is missing its target of reducing greenhouse gas emissions by 65% by 2030 compared to 1990. Instead, the country has only achieved a reduction of 63 percent. This means that Germany has a discrepancy of 331 million tons of greenhouse gases compared to the Federal Climate Protection Act.

The cartographers at Ruhr-Universität Bochum use virtual reality (a so-called "Unity" game engine) to recreate urban scenarios in 3D and highlight possible structural effects. Julian Keil and Marco Weißmann from Prof. Dr. Frank Dickmann's team have developed a kind of innovative laboratory construction kit for this purpose, which creates virtual replicas of traffic and the...
