RBR 2020: what will the habitat of tomorrow look like?
The time of the RT 2012 (Thermal Regulation) will soon ring ... Soon, the RBR (Responsible Building Reflection) 2020 dictate building standards as part of the Responsible Building Plan. Energy consumption, building carbon footprint, indoor air quality ... Anthony Esposito, Founding President of Dulo, tells us more about the future building regulations.
Energy consumption, building carbon footprint, indoor air quality, RBR 2020 is the vast program that succeeds the RT 2012 which focused only on the "thermal standards" of buildings. To help us better understand the new housing regulations of tomorrow, Anthony Esposito answers our questions *.
What is your assessment of RT 2012?
Anthony Esposito: The technical assessment was positive: the RT 2012 pushed the standards to reach an honorable standard. It has also relaunched many roofing, window, or insulation specialists with the need to innovate it has generated. On the other hand, and this is the other side of the coin, a large number of companies were not prepared for this regulation and closed down for lack of skills. Finally, sometimes consumers did not perceivepositive and lasting aspect of this device to capture only the increase in rates.
What are the goals of the RBR 2020?
Anthony Esposito: RBR goes beyond the simple field of thermal regulation of the building and goes beyond it by targeting the carbon footprint of the building and the quality of the air, thus the well-being of the inhabitants. However, for the moment nothing is totally defined. RBR 2020 can imagine that new buildings will be Positive Energy Buildings (BEPOS), that is, they will produce more than they consume energy. Or, likely version, that consumption KWh / m2 / An is Decreased by 30% compared to RT 2012 (50kWh / m2 / year). A BEPOS label could be attributed to autonomous constructions. Finally, this new regulation addresses the subject of improving the air quality of the habitat and the reduction CO2 emissions.
How to do this?
Anthony Esposito: We must build on what the RT 2012 has put in place and deepen it. This affects the insulation of course, and the preference for the ITE (External Thermal Insulation) which stores the calories in the walls to restore them when it is very cold or very hot, and avoid the important thermal bridges. This also goes through the windows (we are at the point in this area), the layout of a renewable energy installing solar panels or photovoltaic panels is not always possible, but a heat pump that redistributes 5 times more energy than it consumes, or a thermodynamic balloon is feasible. The tightness of the air remains at the heart of the subject. And the choice of a double flow with filtration system improves the quality of the air. Regarding the carbon footprint, we must permanently forget some construction methods such as those made from chipboard, cinder block and glass wool. It is necessary to remain coherent on the whole building, to move towards the use of natural materials, ecological as on the choice of a more "responsible" equipment of the house.
But first and foremost, we must review the way of think and design the habitat. France is late. These construction processes have been around for a while in Europe, in the Scandinavian countries, in Switzerland, even in Savoy. Today, it is enough to deposit photovoltaic panels on the roof of our buildings so that they become BEPOS.
What is the cost for the consumer?
Anthony Esposito: This implementation should not cost the consumer more, but it depends on the different actors.
And what about the old buildings?
Anthony Esposito: The thermal regulation of existing buildings applies to existing residential and commercial buildings, during renovation work planned by the client.
The general objective of this regulation is to ensure significant improvement in the energy performance of a building when a client intervenes. The regulatory measures differ according to the importance of the work undertaken by the latter. For example: the regulation applies when the facade remodeling work (repair of plaster or installation of a facing) touches at least 50% of the surface of a facade. But facades made of "industrial" materials: concrete, industrial bricks ... are not concerned. However, there are exceptions: legal and technical impossibilities, risk of deterioration of architectural quality and economic profitability (when insulation work is greater than 10 years). The first two require proof, the other two do not.
* The RBR 2020 should be effective by January 2021.
