Key facts
- 66% of valid DPEs in Saint-Denis were generated from the building's DPE, without a rating measured for the flat itself (29% in mainland France).
- 1.0% of homes with a DPE in Saint-Denis report air conditioning, against 9.2% in mainland France.
- 14% of homes with a DPE in Saint-Denis are on district heating (4.1% in mainland France).
- 15% of homes with a DPE in Saint-Denis are rated F or G, against 12% in mainland France — and the gap persists at comparable building age and type (17%).
Energy and climate ratings
Among 14,596 valid DPEs of homes (excluding generated DPEs) in Saint-Denis, rating C is the most common; 40% reach ratings A to C.
If the homes with a DPE in Saint-Denis had the same mix of building age and type (house, flat) as mainland France, the F+G share would be 17% (+1.9 pt versus the observed figure).
By floor area, the F+G share among homes with a DPE in Saint-Denis ranges from 11% (70-99 m²) to 21% (25-39 m²).
For 16% of homes with a DPE in Saint-Denis 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).
12% of homes with a DPE in Saint-Denis 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 (1,693 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
66% of valid DPEs (28,456) — against 58% 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
969 homes with a DPE (excluding generated DPEs) in Saint-Denis are rated G, i.e. 6.6% of homes with a DPE (7.1% 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).
1,171 homes with a DPE (excluding generated DPEs) in Saint-Denis are rated F, i.e. 8.0% of homes with a DPE (9.6% 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).
2,699 homes with a DPE (excluding generated DPEs) in Saint-Denis are rated E, i.e. 18% of homes with a DPE (20% 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 2,117 F- or G-rated homes with a DPE (excluding generated DPEs) in Saint-Denis whose DPE is still valid on that date, whose published class is reproduced and whose scale could be read, 25% could obtain a certificate of a new rating, at least one class better, downloadable from ADEME's DPE-Audit Observatory. The original DPE remains valid until it expires.

Estimated consumption and cost
The median cost estimated by the DPE in Saint-Denis is €875 a year for a flat (202 kWh of primary energy per m²) and €1,965 for a house (253 kWh/m²). Per unit of floor area, the median cost of a flat is €21 per m² a year (€20 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.

Of those with a known period, 44% were built before 1949 and 11% after 2010.
The collective DPE covers multi-dwelling residential buildings whose building permit application was filed before 1 January 2013, on a timetable set by the number of units (rule and references in the method).
