Design of energy renovation of typical buildings : Elaboration of collection of examples

The energy saving potential by energy renovating the existing building stock in Denmark is very large but the implementation of energy savings is only carried out to a small extend. In order to encourage the completion of energy renovations in buildings there is a need for improving the foundation for evaluation and selection of the optimised solutions. The objective of the project is to develop a method for design of extensive energy renovations that will encourage the completion of energy savings in existing buildings to reach “low energy class 1” level. The development of the method will be based on detailed analysis on the effect of the partial energy saving measures carried out in buildings. The analyses will be made for typical building types and the results will make up an example collection of buildings that represent the total building stock in Denmark. The developed method including examples will constitute a strong and reliable foundation for implementation of the best energy saving solutions in different building types. If done correctly it will also be possible to improve the indoor environment by energy renovations. This important additional benefit will also be evaluated in the form of improved comfort, less health risk and increased productivity.
