Apartment F → E
65 m²Electric heating
65 m² 3-room electrically heated apartment, 380 kWh PE/m²/yr before reform. With the 1.9 coefficient: 314 kWh PE/m²/yr → moves from F to E.

How does it work?
On January 1, 2026, the electricity-to-primary-energy conversion coefficient drops from 2.3 to 1.9. This reduces displayed primary energy consumption by ~17% for electrically heated homes, potentially changing the DPE energy label.

Here is how three typical homes see their energy label change with the new 1.9 coefficient.
65 m² 3-room electrically heated apartment, 380 kWh PE/m²/yr before reform. With the 1.9 coefficient: 314 kWh PE/m²/yr → moves from F to E.
90 m² electrically heated house, 460 kWh PE/m²/yr before reform. With the 1.9 coefficient: 380 kWh PE/m²/yr → exits the "thermal sieve" status.
30 m² electrically heated studio, 250 kWh PE/m²/yr before reform. With the 1.9 coefficient: 207 kWh PE/m²/yr → moves from E to D.
Estimates based on the official calculation (French decree of August 13, 2025). Your actual situation may vary depending on your DPE.
All electrically heated homes benefit from the new coefficient. About 850,000 homes exit the "thermal sieve" classification.
Homes heated by gas, oil or wood are not impacted by this reform. Only the electricity conversion coefficient changes.
