The novelties brought by RT 2012.

The great novelty of the RT 2012 is to limit the energy consumption of new buildings to 50 kWh / m2 / year on average, a variable figure depending on the location of the building. This concerns five sectors: heating, hot water production, cooling, lighting, but also auxiliary devices such as fans and other pumps. As a result, RT2012 will showcase the best-performing products and equipment available on the French market, as well as the renewable energies that are highlighted by the new thermal regulations. In addition, RT 2012 also provides for a significant increase in the number of so-called bioclimatic constructions.

The controversy around RT 2012.

Even before its official release, the new thermal regulations are already controversial. Indeed, critics are firing from all sides, both on the side of the ICEB (the Institute for the Environmental Design of the Building), that of the ecologists. It is mainly criticized by the RT 2012 for not taking into account secondary energy consumption, but nevertheless important as lighting or ventilation of car parks and lifts, outdoor lighting, office automation, but also energy consumed by household appliances. In addition, the new directives call for the installation of air / water heat pumps, a particularly energy-consuming heat pump. A set of points that would come back, according to critics of RT20112, to play the game lobbies all electric and not really put forward passive or positive energy houses and the use of biomass as heating in the woods.

While awaiting the official release of the new thermal regulation that will appear in the official journal of November, DuitDesign encourages you to browse the site of the Grenelle of the environment to form your own opinion on the issue.
