In 2007, the Effinergie association launched its first label “BBC-Effinergie” for new buildings, requiring a primary energy use of 50kWh/m² per year. The label was very successful and became mandatory for all new buildings under the 2012 Energy Performance regulation (RT2012).
When the RT2012 came into force, Effinergie launched its new label "effinergie +"
The “effinergie +” label requires (among others):
- an improved energy performance compared to the regulation;
- tighter buildings than the mandatory level defined in the EP-regulation (up to 20%);
- control of ventilation systems;
- at least class A ductwork (with mandatory justification).
