Some 300,000 social housing units, or 6% of the social housing stock, had an F or G energy label on January 1, 2022, corresponding to thermal strainers, according to a study by the National Social Housing Control Agency (Ancols) published Tuesday.
According to this study, 1% of the social housing stock, or around 50,000 housing units, corresponded to label G, the least efficient, and 5% to label F.
Social landlords are not escaping the timetable set by the Climate and Resilience law of 2021, which plans to prohibit the rental or re-rental of the most energy-intensive housing: those labeled G from 2025, then F in 2028 and E in 2034.
The E label represents 15% of the social housing stock, made up of around five million housing units, according to this study.
More than two thirds of the stock are labeled C (33%) or D (38%), while the most efficient energy classes are very under-represented, with respectively 1% of A and 5% of B housing, the vast majority of which are built after 2010.
The energy renovation of housing is essential to achieve France’s greenhouse gas emissions targets, enabling substantial energy savings in the process.

Smaller social housing units are more likely to be thermal sieves (8% of T1s classified F or G), the method of calculating energy performance diagnostics penalizing small areas.
Individual housing, uncommon in social housing, is also more concerned (11%), notes Ancols.
Thermal strainers are much rarer in the southern and western departments of France. One of the causes is that social housing is on average more recent in these areas, but this is not enough to explain the entire difference, notes Ancols, without detailing possible additional causes.
