Energy Retrofitting of School Buildings to Achieve Plus Energy and 3-litre Building Standards

AbstractThe amount of delivered energy used by educational buildings is equal to approx. 20 million MWh/a, about two thirds of which are used by school buildings. In the next few years, many school buildings will have to undergo major retrofits. Now this is the time to set the course for the future energy consumption of these buildings. In the scope of a demon¬stra¬tion project funded by the Federal Ministry of Economics and Technology it will be shown by which innovative measures the energy consumption of school buildings can be reduced by almost 80% on average. These measures include energy retrofitting of the building envelope, of technical building services, and the use of renewable energy. After retrofitting, some school buildings now achieve plus energy standard, the other ones achieve the 3-litre building standard. Findings of this project will be contributed to SHC Task 47 (Solar Renovation of Non-Residential Buildings)
