  French regulation context ClimatePlan 2004 French goal 2050: “ Factor 4” Grenelle de l’Environnement Thermal regulation  RT 2000 Buildings permits - between 01/06/2001 and 01/09/2006  RT 2005 Buildings permits – between 01/09/2006 and 26/10/2011  RT 2012 Buildings permits – after 28/10/2011* *Apply only for offices, educating buildings. Hostels, retails and others are coming soon.  Basic level of RT2005 corresponds to RT 2000 -8%  Basic level of RT2012 corresponds to RT 2005 -50% Thermal regulation method  C ≤ Cref C = conventional energy consumption C = heating + cooling + hot water + ventilation + lighting  Tic ≤ Ticref Tic = conventional interior temperature (°C) Examples of Cepmax value in France for Offices  Minimum values for Core & Shell: Ubat for RT2005 and Bbio for RT2012 Materials (insulation, windows…) and systems (heating, ventilation…) characteristics must have a better efficiency than some minimum values defined in the thermal regulation. Includes air tightness requirements. 2
