In January 2013, the 2012 Thermal Regulation Standard, or RT 2012, came into force in France.
What energy obligations were imposed on the builders at the time? How has the house construction sector evolved since? Update on the 2012 standard, on the eve of the launch of the RT 2020.
What is the 2012 thermal regulation??
For all building permits for new residential buildings registered since 1 January 2013, builders must comply with the recommendations of the Grenelle Environment Forum, RT 2012.
From now on, the annual energy consumption ceiling must be less than 50kWh / m². This minimum value was however already required for several years to obtain the BBC label effinergie.
The 2012 thermal regulation (RT 2012) is based on 3 main indicators:
- The Bbio index, ie the minimum energy performance requirement of the building;
- The Cep index, which characterizes the primary energy consumption of the building;
- The Tic index, relative to the conventional indoor temperature.
With a decrease in energy consumption and a proliferation of resale opportunities, the standard for thermal regulation has been a turning point for all property owners since 2012.
The goal by 2020? Propose passive houses even positive, ie with a zero energy balance (with excellent insulation and outgoing heat recovery).
New house construction: all about the RT 2020
RT 2012 has really improved the energy performance of new buildings, but the construction sector still accounts for 40% of all energy consumed in Europe. Thus, home builders still have many efforts to provide in the coming years to limit their ecological impact.
The next thermal regulation should be put in place by the end of 2020. Its objective is to tend towards a passive house, known as positive energy, that is to say whose energy balance is totally zero (with an excellent insulation and a outgoing heat recovery).
Among the novelties of the RT 2020, we find:
- heating consumption will be capped at 12 kWh / m²;
- the total energy consumption of the building must be less than 100 kWh / m².
The future thermal regulation also aims to involve citizens in this energy transition project, in order to limit energy waste and promote energy production.
