FAQHigh energy performance labels in FranceFacing the challenge of climate change, France has made ambitious commitments by signing the Kyoto Protocol entered into force since February 2005 : the French government agreed to reduce the carbon dioxide emissions, marker of greenhouse gas emissions, from 2010 on down to the level of 1990. The policy of the thermal regulations 2005 (RT2005) is to encourage builders and contractors to take into account all possibilities of improving the energy performance of the building in a technical framework specified beforehand. Currently, a house according to the thermal regulations (RT 2005) consumes on average between 91 and 150 kWh/m2. The law of the ‘Grenelle Environnement’ (France’s Environmental Round Table) defines the levels of consumption covered by the current thermal regulations (RT2005) and levels of the future consumption :
The High Performance Energy labels reward structures that go beyond current regulations to perform already the future objectives of the ‘Grenelle Environnement’. The HPE 2005 label - High Performance Energy :It corresponds to conventional energy consumption less than 10 % of the conventional reference consumption of the thermal regulations 2005. The HPE EnR 2005 label :This is a HPE label of 2005 with additional requirements for the installation of equipment of renewable energy for heating, and eventually the production of hot water: boiler using biomass, especially wood. The THPE 2005 label - Very high energy performance :It corresponds to conventional energy consumption less than 20 % of the conventional reference consumption of the thermal regulations 2005. The THPE EnR 2005 label :Homes with at least 30% less energy consumption compared to the thermal regulations 2005, with the obligations to install Renewable Energy equipment: thermal solar panels, photovoltaic panels, windcatcher or very efficient heat pumps. The BBC and BBC EFFINERGIE label :The BBC 2005 label (Low energy consumption building), set up by the French order of May 8th, 2007 and published in the Official Journal (Journal Officielle de la Republique Française) of May 15, 2007 specifies that for the new residential constructions, the objective of maximal consumption in primary energy is fixed to 50 kWh/m².year - to modulate according to regions and altitude. Classification of buildingsDepending on the level of annual consumption of primary energy in kWh per m² Energy-plus building (BEPOS) :An energy-plus building is a building that produces more energy than it consumes. This standard will be mandatory for all new buildings from 2020 on. For this scenario it is necessary to minimize the energy requirement by reducing it to a "passive" standard. Thus the term BEPAS or Passive Building has been mentioned in reference with the concept of the Passive house created by our German and Austrian friends (Passiv Haus). An energy-plus building is a passive building (BEPAS) that exceeds its energy needs through renewable energy production. Useful links :
