Energy-intensive building

This is a condominium that has benefited from the new energy renovation aid scheme "Ma Prime Rénov' Copropriété".

In 2020, the condominium voted to carry out a simple facelift with the insulation of only the two gables.

The appearance of "Ma Prime Rénov' Copropriété" was a trigger and prompted the condominium to expand its work program in order to benefit from public subsidies available to all co-owners.

In this context, in-depth awareness-raising work and several communication actions with the union council and the trustee were carried out at the co-ownership level.

A more ambitious and eligible additional work was redefined and voted on at the general meeting of 15/12/2021.

This program consists of carrying out a facelift with ITE (external thermal insulation) as well as the installation of controlled mechanical ventilation.

It makes it possible to achieve an energy gain after work of 36%.

The work began on 03/01/2022 and was completed in early summer 2022.

Reasons for participating in the competition(s)

After awareness-raising and information work, the condominium was able to build a coherent energy-saving work programme, adapted to its configuration and its financial capacity.

The condominium finally voted for its energy renovation at the end of 2021 despite the concern of some co-owners about the financing of the project.

The condominium completed its work at the beginning of summer 2022 and is therefore one of the first condominiums in the "Ma Prime Rénov' Copro" system to complete its rehabilitation.

The energy renovation has enabled the co-owners to benefit from "Ma Prime Rénov' Copro" public subsidies, to upgrade their assets and improve their thermal comfort while saving energy.

The Etang residence therefore bears witness to the success of a coherent and well-financed energy renovation project within the framework of "Ma Prime Rénov' Copropriétés".
