The Effinergie association was created in May 2006 to promote low energy buildings in France. The initiative was taken by regional authorities, and particularly the Alsace, Franche-Comté, Languedoc-Roussillon and Rhône-Alpes regions. The objectives are to combine and optimize implementation of regional approaches, and to federate construction professionals and local communities.
The core measures of the energy concept are:a highly efficient airtight facade system without thermal bridges that reduces the heating and cooling need to a minimum and provides at the same time a high daylight quality. The energy need shall be reduced by factor 5 compared to regular new buildings in the area
