The energy transition law for environmentally friendly growth from the 17th August 2015 stated that to be decent, housing has to meet minimum energy performance criteria. The decree from the 9th March 2017 has clarified these criteria, including energy performance in the characteristics of acceptable housing. Let’s review these additional decency criteria.
What is environmentally acceptable housing?
The decree from 9th March 2017 updates that of 30th of January 2002 concerning the characteristics of acceptable housing. The property is considered as energy-efficient for reasons related to its own design such as its airtightness and its ventilation which have to be appropriate.
The property has to be protected from unwanted air leakage.
The doors and windows of the property, as well as the walls and partitions onto the outside of the property or to unheated parts should have sufficient airtightness. The opening of the rooms into adjacent unheated rooms should be equipped with doors or windows. Finally, chimneys should be equipped with traps. However, these provisions are not applicable in France’s overseas territories.
Luckily, the nature of a dwelling’s decency is determined independently of its occupancy situation (throughout the year by a large family or only a few weeks per year) and the energy cost.
These new decency criteria will begin in 2018
Starting from 1st January 2018, housing will have to be protected from “unwanted air leakage” to be considered as decent. From 1st July 2018 it will have to have an “adequate” ventilation system.
