Renovate a building that is co-owner, it has only advantages: we save energy (and we can lower the cost of property that we rent!), An increase in comfort in the building, and than the value of the property that we hold with other co-owners. But before we see what we have to gain from conducting energy renovation works in co-ownership, we must know how it is organized...

Energy renovation works in co-ownership: the different stages.

By definition, in a co-ownership, you are not alone. And to decide on the energy renovation of a multi-family home, this will obviously require much more time than for a single-family home by its sole owner.

Even if the steps leading to energy renovation work are not fundamentally different than for a standard home, it is necessary that each of them be strictly supervised and validated by the different authorities that manage the co-ownership.
Patience will be more than adequate, since between the preparation of the project and the vote of the first works will run on average 4 to 5 years...

Here are the different steps needed to implement energy renovation projects in co-ownership:

1. Launch of the energy renovation project by the co-owners, the syndic and the union council. Discussions, information search, preparations...
2. N + 1. Vote on the energy audit of the building (or collective DPE), in order to estimate its energy performance; in general assembly and by simple majority. Competition of different auditors, then selection of the one who will carry out the audit.
3. N + 1 or N + 2. The audit is carried out, and the results announced to the co-owners; the auditor issues recommendations and proposals for work. If the co-owners agree, submit a complete program of work to the general assembly.
4. N + 2 or N + 3. Competition between different companies (with specifications in support). All works and specifications must be voted in general assembly.
5. N + 3 or N + 4. Make a financing plan for the works (grants, grants, loans available).
6. N + 4 or N + 5. Vote in the general assembly of the first works (priority).
7. N + 5 or N + 6. Start of work.
8. N + 6... Follow the work.

What order for the work?

So that the energy label of the DPE a building goes back into the greens, we do not operate in any order!

We realize first and at the same time insulation work to put a brake on heat loss.

Then we move on to improve or replace the heating, ventilation and domestic hot water systems of the building.

Eventually and according to what was voted in AG, we can finally decide to set up renewable energies, and improve existing electrical installations (lighting of common areas, elevator...).

What kind of help for co-ownership energy renovation works?

The sore point when we want to undertake energy renovation work in co-ownership, it is obviously the budget. Especially if the amount of work is high, and the work will extend over several months or years.

Generally, co-owners lack the means to secure financing. It is therefore essential to set up a financing plan, especially as many subsidies and general subsidies (CIDD, eco PTZ, 5.5% VAT, etc.) and specific to the co-owners (work fund, tenant's contribution...) are to help co-owners carry out their energy renovation projects in co-ownership.
To find out more, co-owners can get in touch with a energy renovation consultant who will direct them to the one-stop shop for the next energy retrofit.
