The building sector is responsible for around 17 percent of all greenhouse gas emissions in Vienna, a number which should be reduced by two percent every year under the Smart City framework strategy of the City of Vienna. In order to achieve this objective, buildings must be supplied with energy in a more environmentally-friendly way, while at the same time being made much more energy efficient.
The Guideline of the Austrian Institute for Structural Engineering (OIB Guideline) and the building regulations of the provinces make up the legal framework here, regulating the minimum technical requirements for technical building services (e.g. e-charging points) and heating systems. The use of fossil fuels in buildings should be gradually replaced by environmentally-friendly alternatives such as district heating or PV systems. Wien Energie already supplies 380,000 households with district heating today. We are also working on turning Vienna into a city of solar power and are committed to expanding the infrastructure for private charging points for electric cars.
