Tinergie: The energy renovation aid scheme and the installation of solar energy in homes

General Information


Municipality: Brest Métropole

Country: France

Inhabitants: 206.893

Description of Measure and Categorization

Tinergie is a one-stop shop for home renovation created by Brest Métropole in 2012 and run by Ener'gence. Its role is to support any inhabitant of Brest metropole (and Crozon since March 2020) who has an energy renovation project, whether owner or co-owner.

Tinergie is present for all phases of energy renovation of a home:

1. Diagnosis for energy savings: A partner diagnostician (quality charter) carries out a diagnosis for energy savings and identifies the actions to be implemented to improve the energy performance of the home. The diagnosis can be financed up to 50% if at least one of the recommended actions is implemented. 

2. Renovation scenarios: At the end of the diagnosis, the Tinergie adviser proposes renovation scenarios by quantifying the investments, gains and possible financing, presented to the inhabitant who chooses the actions he wants to implement. 

3. Relationship between residents and renovation professionals: Tinergie has an address book of companies committed to a "Tinergie quality charter" to guarantee the reliability of the renovation work. 

4. Estimates and financial file: A Tinergie adviser is available to analyse the various estimates received by the resident and help him to select some for the work to be carried out. He will then detail all the financial (particularly from Brest Metropole) and tax aid that the resident may be entitled to depending on the work selected.

5. Work and verification: Work begins once all the previous stages have been completed. The diagnostician then comes back to carry out a new diagnosis to check that the actions have been properly implemented and to calculate the real energy savings.  

This system is more or less similar for the renovation of condominiums, which are supported by SEMPI and SoliHa, who have developed their expertise on the specificities of condominiums with a long and complex decision-making process. 

Tinergie also supports the development of solar thermal and photovoltaic energy in housing. With the help of the solar cadastre carried out at the initiative of Brest Métropole, a Tinergie adviser studies the various solutions according to the expectations of the inhabitant (pre-dimensioning, cost estimates, earnings, financial aid, etc.), professionals are partners, a quality control at the end of the building site is offered to the owners and a bonus of 800 € can be paid without any conditions for the work (provided that the building is built after 1988 or before, but justifying at least class C). 

A few figures: In 2019, 1 657 people have been supported, 600 homes (condominiums + individual homes) have been diagnosed and 550 homes have been renovated (including 200 BBC). The average energy gain from the energy renovations supported by Tinergie is 50% for a 59% reduction in GHG emissions. The average grant from Brest métropole awarded is 1 780 € per project, i.e. a total of 850 000 € since 2012.

In addition, depending on the level of household income, investment aid from the ANAH is granted.
