In France, millions of homes built before the 90s, and especially before 1975, are still poorly insulated. People see their heating bills reach the sky while this huge energy waste results in the emission of millions of tons of CO2 that contribute to the greenhouse effect. The French government is therefore committed to improving the energy efficiency of existing housing stock, 40% of consumer energy in France. Thermal renovation must meet several requirements: get in line with the European Directives and, in particular, the Building Energy Performance Directive ; control energy expenditure taking into account that existing buildings are more energy consuming than new buildings.
This regulation imposes minimum thermal performance requirements for all equipment installed or replaced in an existing building and applies to the overall building envelope :
DHW (hot water) and cooling systems;
ventilation and lighting systems (excluding individual housing) ;
power generation equipment using a renewable energy source.
Since November 1. 2007 (French Official Journal May 17, 2007), the thermal regulation element requires that when insulation works are carried out in existing buildings (installation or replacement), they meet a minimum level of thermal performance.
