Interactive map – Infographic. Housing: how many “thermal filters” in your apartment?

Where are the heat sieves?

The social stock of rental of good students: The social stock consumes much less energy than the private stock (7% of labels F and G, compared to 18.7%), which is explained by a high prevalence of collective heating of gas, as well as a specific renovation effort. The private rental stock comprises the homes that consume the most energy, with about 23% of homes labeled F or G, while owner-occupied homes are only 17% labeled.

Homes less prudent than apartments, except when they are small …: Very energy-intensive housing is more common among single-family homes than in homes located in group homes (18.4% vs. 14.7%). Smaller homes consume the most energy: about 36% of homes under 30 m² have an F or G label, which is only the case for 13% of homes over 100 m².

Older Homes May Work Better: The SDES notes “a general trend toward less energy-efficient labels as new thermal building construction regulations are introduced.” Recent builds clearly tend towards A or B labels, particularly since the early 2010s.

More “strainers” in the mountains and in rural areas: The proportion of houses labeled with F or G is lower in the departments near the Mediterranean arc or south of the Atlantic coast for which the climate is milder and the needs reduced heating (6% of houses with high energy consumption in the Atlantic Pyrenees, the Landes and the Gironde). On the contrary, it is higher in certain rural and / or mountainous departments (more than 40% in Nièvre and Creuse, and up to 46% in Cantal).
