The European building stock shows high potential for energy and greenhouse gas reductions. At the same time the current renovation rates are too low and high performance renovations are not always achievable.
The optimum balance between the primary energy / greenhouse gas reduction and the renovation costs has to be found. The whole life cycle of the building has to be considered and therefore Life Cycle Cost (LCC) calculations and Life Cycle Impact Analysis (LCIA) are of importance.
Furthermore the optimum balance between energy conservation or efficiency measures and renewable energy generation on-site has to be defined as well.
This paper shows some suggestions to answer these issues and was prepared within the frame of the IEA EBC Annex 56 research project.
