The Commission is in the process of updating some of the content on this website in light of the withdrawal of the United Kingdom from the European Union. If the site contains content that does not yet reflect the withdrawal of the United Kingdom, it is unintentional and will be addressed.

Key points concerning the designCombined natural ventilation and mechanical ventilation with air-conditioning and some heat recovery. Use of perforated shading panels to reduce direct solar gain while allowing natural day-lighting. Use of external insulation to reduce heat loss in winter and to provide internal thermal mass, in conjunction with night-time free cooling to reduce peak summer temperatures. Extensive use of natural lighting to reduce energy consumption by artificial lighting.

Translation of the title: Guidelines for energy renovation of domestic buildings
Post date: 12 Set 2009
Type: Publication

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.

Focusing on energy consumption and indoor thermal climate the following topics have been investigated: • Light and Heavy floor heating system • Insulation thickness in the floor construction • Linear thermal transmittance at foundation/floor construction • Control of the floor heating system Supply temperature Supply temperature controlled by the outdoor temperature Night lowering of the room temperature Start/stop difference (Dead band) • Room temperature and energy consumption • Floor coverings

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.
