Heating, domestic hot water

The main changes are: new buildings: the maximum allowed annual primary energy demand will be decreased by 30 % in average. The thermal requirements to the building envelope will be tightened by 15 % in average. existing buildings: in major renovations the thermal requirements for building envelope components are tightened by 30 % in average (facade, windows, roof). Alternatively the primary energy demand and the average transmission loss coefficient after the major renovation may not exceed the factor 1.4 compared to the requirements for new buildings.

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 ground coupled capillary tubes in the plastry of the ceilings for a comfortable and stable indoor climate in summer and winter
