To know clearly the energy consumption and the greenhouse emissions of a housing, there are not 36 solutions: it is necessary to make a Diagnosis of Energy Performance (DPE). But when it comes to a condominium, how does it go?

Co-ownership: energy audit or collective DPE?

When you want to start co-ownership energy renovation work, you have to start from the beginning.
Namely: assess whether the lots that make up this condominium are rather energy-intensive, and what work should be done in priority.

To evaluate the energy performance of a dwelling, we usually think "DPE". But for condominiums, it's a little different, and there are two types of evaluation: collective DPE and the energy audit.
That we are reassured, it is very easy to determine what type of diagnosis depends on our co-ownership:

  • The energy audit is mandatory for buildings whose building permit filing date is before June 1, 2001, and which simultaneously include these 3 characteristics:
    1. The condominium includes 50 lots or more.
    2. The condominium has a main use of dwelling.
    3. The heating system is collective to the condominium.
  • The collective DPE applies to all buildings equipped with a collective heating or cooling system (and which are obviously not concerned by the energy audit). By January 1, 2017, all the buildings concerned must have made their collective DPE.

Once this collective DPE achieved, it will no longer be necessary for each co-owner to remake individually if he wants to rent or sell his home. Indeed, the collective DPE is valid for each of the lots. On the internet:

DPE collective condominium: how's it going?

In a joint ownership, it is obligatorily the trustee of co-ownership which must register the decision to carry out a collective DPE on the agenda of the general meeting of the co-owners.
The co-owners of the GA will then vote by majority, and will decide the professional who will achieve the collective DPE (certified and accredited by the French COmit of Accreditation, COFRAC).

DPE collective condominium: what does it change?

What is interesting in the realization of a DPE condominium is that the collective DPE is also worth for common areas only for the private portions. Thus, when a owner of a lot will want to rent or buy it, he will not have to multiply the steps with the trustee to have information on the common parts.

In addition, as part of a condominium, the group DPE can replace an individual DPE, because it's worth for every lot. The owners will not be obliged to redo a DPE if they want to sell or rent a unit of the building.
