Energy audit is added to the DPE when the latter reveals poor performance, expressed in the classification from A to G. It is applied, at the time of sale, to individual houses and apartments located in a single property, thus excluding houses located in condominium. Its aim is to go further than the DPE in the accurate analysis of energy performance and to propose work to improve efficiency.
A progressive timetable, a entry into force considered “hurried”
The decree published today confirms the timetable announced by public authorities late last year. Thus, houses classified as F and G must, in order to be sold, be subject to inspection from 1 September. Housing will be subject to this obligation on January 1, 2025. This will be followed by Housing Category on January 1, 2034. Note that this control is valid for five years. The list of people who are authorized to conduct the test includes diagnosticians, architects and many professionals if they have the qualifications.
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 is too early, because “The industry could not prepare properly”. The software is not ready, the technicians are not trained and, as a result, the checks will either not be performed or will be performed insufficiently. Especially from “the stock of houses F and G is much bigger” from the entry into force of the new DPE. Sidiane reiterates in a press release its request for entry into force, which has been postponed to 1 January 2023.
Formulate the distribution of losses
The decree issued on the same day specifies the content of the energy inspection. It should take the information from the DPE and move on, with a diagram that will determine the distribution of heat loss. It must also indicate, where appropriate, the existence of control systems and the ventilation or aeration conditions of the building prior to work.
In particular, it should provide an indication of annual energy consumption, total annual consumption and greenhouse gas emissions. The audit should, last but not least, contain job descriptions, describing each of the positions and the expected energy savings. These job proposals are made according to two scenarios.
Reach the level of a high-performance renovation, with two work scenarios
A first proposal provides for a gradual work process to be an effective renovation, the decree explains. Each of the steps “does not jeopardize the technical or economic feasibility of the following steps”. This course of work includes in particular the study of the six workstations commonly referred to: wall insulation, low floor insulation, roof insulation, replacement of exterior frames, ventilation, heating production and domestic heat. water as well as the relevant interfaces.
Obligations to achieve energy efficiency are related to this project: thus, the first stage makes it possible to achieve a profit of at least one category and at least the achievement of category E, and the final stage must allow the achievement of at least category B For buildings of category F or G before work, the work route includes an intermediate stage that allows access to at least category C, determines the decree.
The second working proposal must provide for a one-stage work route, therefore a total renovation, to be a high-performance renovation, ie a level of performance at least equal to that of category B. This route also includes the study of the six workstations.
By way of derogation, the decree provides that if the technical, architectural, hereditary or cost characteristics of the project do not allow the achievement of performance category B, the work path provides for the processing of six jobs and allows at least Category C performance for Category E buildings before from work, performance class D for class F buildings before work, performance class E for class G buildings before work. This is an improvement of at least two classes.
The six jobs are considered processed “Once the auditor certifies that they have reached a high level of performance using the best available techniques and compatible with the characteristics of the specific building”clarifies the text.
