The Energy label of a dwelling as well as its impact on prices are linked to the nature of the property, its location as well as its construction period. Depending on the sector, the housing supply largely includes criteria other than the Energy label alone as determining factors in the choice of housing. It is not, in itself, a determining factor in the choice of accommodation; but it can be a criterion of price variation.
A highly variable breakdown by department of the Energy label of homes sold
The proportion of homes sold qualified as “extremely poorly performing homes” (FG class) is very heterogeneous across the region.
It is lowest (3%) in the departments close to the south of the Atlantic coast and the Mediterranean arc such as the Var, the Pyrénées-Atlantiques, the Gironde and the Bouches-du-Rhône. Conversely, it is strongest in the more rural and / or mountainous departments such as Cantal (36%), Hautes-Alpes (34%), Creuse (30%), Alpes-de-Haute -Provence (30%) and Savoy (29%).
The share of class AB homes sold is less heterogeneous in the territory, even if its variations are not negligible according to the departments: from 1% in Meuse, Haute-Marne, Creuse and Cantal to at least 12% in the Pyrénées-Atlantiques, the Gironde, the Bouches-du-Rhône, Ille-et-Vilaine and Hérault. The share of homes sold built after 2010 is also among the lowest in Meuse, Haute-Marne, Creuse and Cantal (from 3 to 6%) and among the highest in Pyrénées-Atlantiques, Gironde, Bouches-du-Rhône, Ille-et-Vilaine and Hérault (from 10 to 13%).
An impact that is all the weaker the higher the level of "real estate tension"
The analysis of the green value at regional level shows the weakness, if not the absence, of an impact of the Energy label on housing prices in Île-de-France. This finding can be explained by the specificity of the Ile-de-France real estate market, characterized in particular by demand greater than supply and therefore tension on the market.
Whether it is the capital gain on apartments or the capital loss on houses, the impact on prices generated by the Energy label, compared to a “D” class housing, is, on average, the lower the higher the level of “real estate tension”. For example, compared to class D apartments, class AB apartments sold, on average, 6 to 9% more expensive in the most "tense" areas (A and B1) and 14 to 21% more expensive in the least “tense” (B2 and C).
