The energy audit is added to the APB, when it reveals a poor performance, expressed in the classification from A to G. It applies at the time of sale to individual houses and apartments that are in one property, so excluding homes located in a condominium. It wants to go beyond ECD in the accurate analysis of the energy characteristics, and to propose performance improvement works.
A progressive schedule, an entry into force considered “rushed”
the decide published today confirms the timetable announced by the government late last year. For example, homes with class F and G must be subject to an audit from 1 September in order to be sold. This obligation will apply to E-housing on 1 January 2025. G-classified housing will follow on January 1, 2034. Please note: this audit is valid for five years. The list of individuals authorized to conduct the audit includes diagnosticians, architects, and many professionals, as long as they are qualified.
The entry into force of this obligation had already been postponed by the government “after consultation with professionals” of the industry. For Sidiane, who represents real estate diagnostics, this remains very premature, because “sector has not been able to prepare properly”† The software is not ready, the technicians are not trained and the audits will therefore be either not or poorly done. Especially since “the stock of houses F and G is much larger” since the entry into force of the new APB. Sidiane reiterates in a press release its request for entry into force has been postponed until January 1, 2023.
Schedule the distribution of losses
l’Stop published the same day, specifies the content of the energy audit. He will have to extract the information from the DPE and move on to a diagram showing the distribution of heat losses. It should also state, if applicable, the existence of control systems and the conditions for aeration or ventilation of the building before the works.
In particular, it should provide an indication of annual energy consumption, total annual consumption and greenhouse gas emissions. Last but not least, the audit should include work proposals, describing each of the functions and the expected energy savings. These work proposals are made according to two scenarios.
Reach the level of a high-end renovation, with two work scenarios
An initial proposal provides for a phased process to achieve an efficient renovation, explains the decree. Each of the steps “does not affect the technical or economic feasibility of the following steps”† This work includes in particular the study of the six workstations commonly referred to: wall insulation, low floor insulation, roof insulation, replacement of exterior joinery, ventilation, production of heating and domestic hot water and associated interfaces.
There are obligations associated with this work to achieve energy performance: the first phase thus makes it possible to achieve at least one class of profit and at least class E, and the last phase must make it possible to achieve at least class B For buildings of class F or G before the works, the work trajectory includes an intermediate stage that makes it possible to reach at least class C, the decision specifies.
The second work proposal must provide for a single-stage work trajectory, i.e. a global renovation, to form a high-performance renovation, ie a performance level at least equal to that of class B. This trajectory also includes the study of the six workstations.
In derogation from this, the Decree provides that if the technical, architectural, monumental or cost characteristics of the work do not allow to achieve performance class B, the work trajectory provides for the treatment of the six workplaces and makes it possible to use at least performance class C for buildings of class E before works, performance class D for class F buildings before works, performance class E for class G buildings before works. That is an improvement of at least two classes.
The six workstations are considered processed “once the auditor certifies that they have been brought to a high level of performance using best available techniques and compatible with the characteristics of the building in question”clarifies the text.
