In order to meet the objectives set by the Grenelle de l'Environnement, the 2012 Thermal Regulations will soon come into force. Its principle: Improve the energy efficiency of buildings from their design in order to reduce their energy needs. Understanding the Thermal Regulations 2012 RT 2012 takes up the main requirements of the BBC-Effinergie label. This new thermal regulation eliminates the reference values and the safeguards of RT 2005 in favor of 3 performance requirements: bioclimatic need, energy consumption and interior temperature. This improvement in the energy efficiency of buildings aims to generalize “low consumption buildings and houses” from: October 28, 2011 for public and tertiary buildings January 1, 2013 for residential What changes with RT 2012 The new thermal regulations focus on energy efficiency from the design of the building: Energy consumption of less than 50 kWh / m² / year The requirements of RT 2012 are positioned at the level of the BBC-Effinergie label with an obligation of maximum primary energy consumption (Cmax) less than or equal to 50 kWh / m² / year, modulated according to geographical location, altitude, average surface area, the type of use of the building, and the greenhouse gas emissions of the energies used. The "Bbiomax" Bioclimatic need This new indicator defines a limitation of the energy requirement for heating, cooling and lighting. It must be provided when filing the Building Permit. It particularly enhances the level of insulation, joint ownership and bioclimatic design (access to natural lighting, solar gain, etc.). Thus, a well oriented building, with good insulation will have a low B Bio and will be able to meet this requirement. The reference indoor temperature (Ticréf) A reference indoor temperature (Ticréf) not to be exceeded to guarantee summer comfort. RT 2012 in practice Treatment of thermal bridges: the hunt for thermal bridges began with RT 2005; it continues with an overall limitation of thermal bridges. Traitement de l'étanchéité à l'air avec une exigence de perméabilité à l'air du même niveau que celui du label BBC Effinergie : 0,6 m3/(m².h) en maison individuelle, 1 m3/(m².h) en collectif. Surface minimale des baies : pour le résidentiel, la surface des baies devra être supérieure à 1/6ème de la surface habitable. L'éclairage naturel sera donc privilégié. Recours obligatoire à des énergies renouvelables pour la production d'eau chaude sanitaire en maison individuelle. Mesure ou estimation d'énergie pour les principaux usages des occupants en logement, dans un but pédagogique envers l'occupant. A real breakthrough in the way buildings are designed, RT 2012 requires real training for professionals in the face of new building energy performance requirements.
