As we have already mentioned in our previous posts, the new DPE from July 1, 2021, will take into account the energy consumption but also the rate of greenhouse gas emissions of housing. It is the worst of the two scores that will be retained as the final label. For example, if the dwelling consumes 248 kWh of energy per square meter per year, the ECD will have an energy grade E and if it emits 75 kg of CO2 per square meter per year, the climate grade will be F. It is therefore the second grade that will constitute the final grade of the dwelling.
The owner will have to provide supporting documents
These documents (invoices for work, statements of charges, appliance maintenance contracts, tax credits, renovation bonuses, etc. ….) must be given to the diagnosticians so that they can enter several data that will then allow them to evaluate the consumption and greenhouse gas emission rate of the property. Each element included in the DPE (wall materials, insulation, types of windows, floors, heating, etc.) must therefore be noted and justified.
What will happen if no supporting documents are provided?
The diagnostician will base himself on the year of construction of the property to estimate the energy performance and will retain the most common elements according to the construction period. Indeed, the declarations of the owners cannot be taken into account and it will be the most unfavorable situation that will be retained, hence the importance of providing as much evidence as possible!
