- 13% of homes with a DPE in Strasbourg are on district heating (4.1% in mainland France).
- Natural gas heats 46% of homes with a DPE in Strasbourg, against 36% in mainland France.

Energy and climate ratings
Among 63,908 valid DPEs of homes (excluding generated DPEs) in Strasbourg, rating D is the most common; 39% reach ratings A to C.
If the homes with a DPE in Strasbourg had the same mix of building age and type (house, flat) as mainland France, the F+G share would be 12% (+2.9 pts versus the observed figure).
By floor area, the F+G share among homes with a DPE in Strasbourg ranges from 7.5% (70-99 m²) to 11% (100 m² and over).
For 23% of homes with a DPE in Strasbourg 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).
11% of homes with a DPE in Strasbourg 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 (7,232 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
41% of valid DPEs (43,892) — against 31% 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
1,654 homes with a DPE (excluding generated DPEs) in Strasbourg are rated G, i.e. 2.6% of homes with a DPE (4.0% 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).
4,006 homes with a DPE (excluding generated DPEs) in Strasbourg are rated F, i.e. 6.3% of homes with a DPE (7.0% 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).
11,240 homes with a DPE (excluding generated DPEs) in Strasbourg are rated E, i.e. 18% of homes with a DPE (15% 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 5,603 F- or G-rated homes with a DPE (excluding generated DPEs) in Strasbourg 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. The original DPE remains valid until it expires.

Estimated consumption and cost
The median cost estimated by the DPE in Strasbourg is €925 a year for a flat (194 kWh of primary energy per m²) and €2,025 for a house (220 kWh/m²). Per unit of floor area, the median cost of a flat is €19 per m² a year (€17 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.

21% of DPEs of F- or G-rated homes in Strasbourg include a first costed package of works. Its median cost ranges from €5,250 (low estimate) to €8,250 (high estimate). These are the ranges entered by assessors, not quotes.
Prices and green value
No price per m² in Strasbourg: Bas-Rhin, Haut-Rhin and Moselle use the land register, and their sales are not in DVF.
Estimated advertised rent in Strasbourg, charges included, all DPE ratings combined: €15.57 per m² per month for a flat (prediction interval €11.86 to €20.43), €15.74 per m² per month for a house (2025 rent map).
Co-ownerships and collective DPE
The national register of co-ownerships lists 5,725 co-ownerships in Strasbourg (Q3 2025 file, all construction periods), with 100,493 residential units in total: 21 have more than 200 units used as homes, offices or shops, 387 between 51 and 200, and 5,317 with 50 units or fewer. Of those with a known period, 41% were built before 1949 and 8.8% 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). ADEME's database holds 3,795 valid building-level DPEs in Strasbourg, single-owner buildings included; one building may have several.
347 co-ownerships in Strasbourg are flagged in the register as having received an Anah grant for owners' associations, and 161 are in a priority urban-policy neighbourhood (QPV).
