As of next September 1, single-ownership accommodation whose energy performance diagnosis reveals an F and G classification will be required to undergo an energy audit (valid for 5 years).
The latter will have to take the information from the DPE and add a diagram specifying the distribution of heat losses. It must also mention, where applicable, the existence of control devices as well as the conditions of aeration or ventilation of the building before the works.
Besides, it must indicate the annual energy consumption, the total annual consumption, and the greenhouse gas emissions. The audit must, last but not least, contain work proposals, including the description of each of the positions as well as the expected energy savings.
