Facing the need to achieve building energy costs and CO2 emission levels at 80% lower than todays levels, there is a wealth of experience and development happening in Europe. Not only in new buildings, but also in the existing stock solutions are being developed and demonstrated. The presentation will highlight Trecodome's projects based on the passive house concept, and address modern methods of fabrication, as well as solutions for historical and protected buildings.

Experiences are reported from advanced examples within the Treco group of European social housing providers, and the latest developments about prefabricated timber facades for existing buildings from E2ReBUILD, a European Commission supported R&D project in six EU member states.
