Energy and climate ratings
Among 36,424 valid DPEs of homes (excluding generated DPEs) in Aix-en-Provence, rating C is the most common; 62% reach ratings A to C.
If the homes with a DPE in Aix-en-Provence had the same mix of building age and type (house, flat) as mainland France, the F+G share would be 4.7% (+0.9 pt versus the observed figure).
Small homes are the most often poorly rated in Aix-en-Provence: 5.2% of assessed homes under 25 m² are rated F or G, against 2.7% for those of 70-99 m².
For 14% of homes with a DPE in Aix-en-Provence whose published class is reproduced, the climate rating (greenhouse-gas emissions) sets the DPE class: the final rating is the worse of the two (18% in mainland France).
13% of homes with a DPE in Aix-en-Provence whose published class is reproduced would change rating with 5 kWh/m²/year of consumption, or 1 kg CO₂/m²/year of emissions, more or less: they sit on a class boundary (4,847 homes; 12% in mainland France). For them, a small measurement gap or a minor work can move the letter.

DPEs generated from the building’s DPE
29% of valid DPEs (15,000) — against 27% in the département and 29% in mainland France — were produced from the building's DPE: their rating was not measured for the flat itself. They are shown separately: their ratings are not mixed into the figures above.

G, F and E ratings: the decent-housing timetable
284 homes with a DPE (excluding generated DPEs) in Aix-en-Provence are rated G, i.e. 0.8% of homes with a DPE (0.8% in the département, 4.4% in mainland France). Since 1 January 2025, a G-rated home no longer meets the energy performance level of decent housing (Law 89-462, s. 6).
1,080 homes with a DPE (excluding generated DPEs) in Aix-en-Provence are rated F, i.e. 3.0% of homes with a DPE (3.1% in the département, 7.2% in mainland France). From 1 January 2028, rating F will no longer meet the energy performance level of decent housing (Law 89-462, s. 6).
3,686 homes with a DPE (excluding generated DPEs) in Aix-en-Provence are rated E, i.e. 10% of homes with a DPE (10% in the département, 17% in mainland France). From 1 January 2034, rating E will no longer meet the energy performance level of decent housing (Law 89-462, s. 6).
On 1 January 2027, the electricity primary-energy conversion factor drops from 1.9 to 1.7 (order of 19 August 2026). Among the 1,358 F- or G-rated homes with a DPE (excluding generated DPEs) in Aix-en-Provence whose DPE is still valid on that date, whose published class is reproduced and whose scale could be read, 32% could obtain a certificate of a new rating, at least one class better, downloadable from ADEME's DPE-Audit Observatory.

Estimated consumption and cost
The median cost estimated by the DPE in Aix-en-Provence is €715 a year for a flat (164 kWh of primary energy per m²) and €1,515 for a house (142 kWh/m²). Per unit of floor area, the median cost of a flat is €17 per m² a year (€16 in the département, €19 in mainland France). This cost is conventional: it assumes standard use and the energy prices in force when each DPE was issued, not a household's actual bill.
