Chasse à la maison

This document has become essential for the rental or sale of real estate, whether for residential or professional use.

We have the double certification which allows us to carry out the classic DPE for residential use and theDPE MENTION Villeneuve d'Ascq for your commercial, industrial and warehouse premises.

The realization of the DPE is relatively complex.

For buildings for commercial use or homes built before 1948, the DPE is based on gas and electricity bills according to the means of heating divided by the living or useful area depending on the type of building. This type of calculation has the advantage of sticking to the reality of the consumption of the inhabitants, on the other hand it can involve misunderstandings if housing is inhabited by a single person, if it is occupied only 6 months of the year and if their occupants heat little or a lot compared to normality which is 19°. The same goes for commercial premises in Lille if the activity requires little or a lot of heating means, if it requires little or less energy to operate or produce.

For homes built after 1948, the 3CL calculation method is used, which is a method for calculating energy loss based on the typical consumption of a house occupied by a family of 4, for a heating temperature of 19° and calculated on the typical consumption of the last thirty years. This type of calculation allows a standardization of the method of calculation of the DPE in Lille, nevertheless it has weaknesses because the global warming of these last 10 years is indisputable and if the housing is occupied by a greater number of people, it will consume more. than what the DPE provides and vice versa if the accommodation is occupied by less than 4 people.

The notion of energy performance given by considering standardized use is fundamental.

What is the price of an ECD Villeneuve d'Ascq diagnosis?

The price depends on the type of DPE to be carried out and the surface area of the property.

For example, for an apartment or a house in Lille metropolis of 100 m², the price is €140 including tax to carry out the simple DPE or €200 including tax for a Projected DPE or DPE Audit in order to study the most appropriate recommendations in order to achieve real energy performance for housing in Lille. During the DPE audit we are also led to use a thermal camera in order to control thermal bridges and the correct placement of insulation under the roof or in the walls.

Below is an example of photos obtained during the study of a house built in 2004.
