The RT2012 energy regulation, constrains consumption on new builds
The RT2012 came into force for residential properties in January 2013 with an expected increase in building costs of between 8 - 15%.
In line with European regulations, France's sustainable development policy aims to limit the amount of energy consumed by householders, reducing household consumption to one third of the present average.
By creating passive houses, that is those that reduce the loss of heat by using insulation and by, literally, sealing up the heat loss gaps, they move another step on the ecological way. Yet more is to come, as in 2020 the French will introduce a requirement for new houses to not simply conserve but to produce energy.
Presently a new build must incorporate a renewable energy source but in the future houses will have to add energy back into the system.
I asked a carpenter Clémence Bazin if she thought the teams would have the necessary skills to cope? Clémence said that there is no sudden step, as constructors have learnt how to make eco-homes from the RT2005 as well as a building standard for low energy consumption, called the BBC Bâtiments Basse Consommation d'Energie .
The French paper Le Monde in May 2014 wrote that this year could have the lowest number of new builds if the current uptake continues.
For the Connexion article, "New homes must save energy from the start," I interviewed, Irena Czekierska and Clémence Bazin.
