ECD for housing built before 1975: a new formula as of November 1, 2021

As a result of the analysis performed on the new DPE, a new method of calculation which takes into account the identification and correction of anomalies for dwellings dating from before 1975 was specified in an order published in Official Journal October 14, 2021.

This new method may be applicable from 1^er November 2021, the time it takes for corrections to be made to the software used by the diagnostics.

For housing built before 1975 and rated F or G, EPDs will be automatically reissued by the diagnostics, at no cost to the owners.

For housing built before 1975 and rated D or E, owners will be able to request a reissue of their EPD, at no additional cost.

Diagnostics will be compensated for the costs incurred in reissuing these EPDs.
