BBC label – BBC Effinergie® - A low- energy building

Currently, a house corresponding to the thermal regulations 2005 (RT 2005) consumes an average of 91 and 150 kWh/m2.

"Low energy consumption buildings, BBC 2005", established by the decree of May 8, 2007 and published in the Official Journal (Journal Officielle de la Republique Française) of May 15, 2007.
For new residential constructions, the objective of maximal consummation of primary energy is set at 50 kWh/m².year, to modulate according to regions and altitude.

Taken into account is the consumption of so-called conventional primary energy: heating, cooling, ventilation, auxiliaries, production of domestic hot water and lighting facilities.

The label Effinergie is assigned to houses that meet the requirements of the BBC label (Low-energy Building) with in addition, the requirement to measure the tightness of the air.

The label is BBC corresponds to the level A on the energy scale and it shall be valid from 2012 on.

Classification of buildings

Depending on the level of annual consumption of primary energy in kWh per m²

label BBC - BBC Effinergie

As for appliances, there are seven levels ranging from economical housing (Class A), with an annual consumption of primary energy for heating, hot water and cooling below 51 kWh/m2/year up to a full energy consuming building (G).

This indicator should be complemented by a breakdown between renewable and fossil fuels and an estimate of the cost in euros including subscriptions and contributions to global warming kg equivalent CO2 m2/year.

The level of consumption covered by the current thermal regulations (RT2005) and future (Law of the Grenelle Environment) is :
