Energy and climate ratings
Among 41,530 valid DPEs of homes (excluding generated DPEs) in Saint-Étienne, rating D is the most common; 24% reach ratings A to C.
If the homes with a DPE in Saint-Étienne had the same mix of building age and type (house, flat) as mainland France, the F+G share would be 12% (+0.1 pt versus the observed figure).
By floor area, the F+G share among homes with a DPE in Saint-Étienne ranges from 9.5% (70-99 m²) to 15% (25-39 m²).
For 17% of homes with a DPE in Saint-Étienne 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-Étienne 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 (4,819 homes; 12% in mainland France). For them, a small measurement gap or a minor work can move the letter.

10,102 homes with a DPE (excluding generated DPEs) in Saint-Étienne are rated E, i.e. 24% 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 4,915 F- or G-rated homes with a DPE (excluding generated DPEs) in Saint-Étienne whose DPE is still valid on that date, whose published class is reproduced and whose scale could be read, 15% 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 Saint-Étienne is €1,115 a year for a flat (219 kWh of primary energy per m²) and €1,985 for a house (214 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.
