The French BBC Effinergie ® label is intended to identify new buildings or parts of buildings that comply with new very low energy requirements that contribute to achieving the 2050 targets: to reduce emissions of greenhouse gases by 4. It is defined by the Ministerial Decree of 3 May 2007. The reference values are defined by the EFFINERGIE® association and include, for example, a ¨maximum consumption target for new residential constructions of 50 kWhep/m²/year.¨
The EFFINERGIE ® label was officially recognized by the signature of the partnership agreements between EFFINERGIE ® and certifiers accredited by the State for the issuance of the statement Effinergie BBC on 19 June 2007. New buildings can be labeled BBC effinergie ® through a certification process and based on a calculation according to the method of calculation of the RT 2005.
The thermal regulation RT 2005 sets targets for air permeability of the building envelope and includes a reference value on a the airtightness quality. The BBC EFFINERGIE ® label goes further in its demands and requires a measurement of the air permeability of the building on the construction site.
