Almost 400,000 fewer energy filters in France between 2022 and 2023

Of the 30 million prime residences as of January 1, 2023, 4.8 million housing units (or 15.7% of the prime residential stock) are rated F or G. In 2022, there were 5.1 million housing units, or 17.1% of the stock .

The number of energy grids in France is decreasing. This follows from the latest report of the National Observatory of Energy Renewal. France actually has 30 million primary residences. Among them, 1.8 million housing units were energy efficient as of January 1, 2023, or 6% of the shares. They have a DPE designation of A or B. In contrast, about 4.8 million households, or 15.7% of the stock, are energy grids, that is, they have an F or G DPE designation.

Compared to the previous year, this represents a decrease of 380,000 energy networks. As of January 1, 2022, France had 5.1 million nets, or 17.1% of the stock. “The share of F flats thus moves from 10.2 to 9.4% (-207,000 housing units) and G housing units from 6.9 to 6.3% (-171,000 housing units). Among G housing units, the share very energy-intensive (conventional final energy consumption higher than 450 kWh/m²) increases from 1.8% to 1.7% (- 48,000 housing units)”, specifies the study.

Among second and empty homes, the proportion of energy-intensive homes is higher than among primary residences. Almost 30% of second homes, i.e. about 1.1 million homes, and 24% of unoccupied homes, i.e. about 0.7 million, are thus estimated to have energy leaks (marked as F and G). “In total, of the 37 million housing units in the entire fund (main residence, secondary residence, vacant apartments), the number of energy networks as of January 1, 2023 is estimated at 6.6 million (17.8% of the stock) compared to 7.1 million (19, 5%) in 2022, a decrease of 7%,” the observatory notes.

Houses are, on average, more energy-intensive than apartments. The share of housing in category F or G is 21.6% for houses and 17.1% for apartments in the private rental fund. The proportion of housing with high consumption (marked E, F, G) varies depending on the region. This proportion is lowest in regions near the Mediterranean arc, in Corsica or, to a lesser extent, on the Atlantic coast, where the climate is milder and the heating demand assessed by DPE is less significant.

Conversely, it is highest in the center and north of France and in Ile-de-France. Île-de-France thus presents the most unfavorable situation with 21.7% of energy filters and 47.5% of flats classified as main residences from E to G. The Observatory explains: “This is mainly explained by the significant proportion of small flats in this region (43% of flats less than 60 m2 compared to 27% on average), with these houses having the highest proportion of colanders (31.3% for areas less than 30 m2; 19.7% between 30 and 60 m2).
