One of the first BBC co-ownership renovations, guaranteed by a global energy performance contract. Beyond the high energy ambition of this project, this co-ownership contracted an energy performance contract to ensure the reality of energy savings. Another particularity of this project: the work was carried out by a group of local SMEs, organized around the company CHANEL, joint agent of the group and led by the company OPERENE - thus allowing to combine an ambitious global energy renovation and the development of local building SMEs.

Owner approach of sustainability
The condo has set the goal of BBC renovation performance level. The client wanted to entrust the realization of the work to a group of local SMEs, organized around a representative (company CHANEL) and led by the company OPERENE. The companies of the group have committed themselves on the basis of an 8-year performance contract. A process of accompaniment of co-owners was put in place upstream of the works, as well as information / awareness sessions.
It is a set of three buildings R + 3 to R + 4 totaling 50 lots, on a ground in front of road of a commune of the belt of Lyon. The thermal insulation from the outside of all the facades, as well as the loggias, allowed to bring a new architectural look, which was expressed through the choice of colors.

Building users opinion
Opinion of the president of the union council of the co-ownership:
"- very great satisfaction of the occupants for the thermal comfort: regular temperature between the day and the night
- air quality: removal of wet areas on the walls, reduction of kitchen odors
- outdoor lighting: significantly better (see too much) and lower consumption
- double glazing: the noise of the street does not get along almost.
- environment: the new appearance of the facades is very popular: light gray and orange colors, basement and garages in dark gray, new guardrails of the smoked glass balconies. "
The testimony of a co-owner dated June 6, 2019:
"I wanted to give you a feedback on the quality of the renovation work carried out in our condominium and thank you and all those who have participated from near or far. My entourage is unanimous, it is a real success aesthetic question as well as from a comfort point of view inside. I myself am happy to go home and I find the buildings very "class" seen from the main street. "

Management / Mode contractuel
The novelty of this project lies in the establishment of a global performance contract within a private condominium. The commitment is carried by a group of companies, with an agent of solidarity, the company CHANEL, and led by the company OPERENE. This group of companies responded to a consultation for a REM (construction-operation-maintenance) contract after the renovation project was drafted by a project management team.
The management, the union council and the co-owners are reassured at the time of the start of the work because they can count on a commitment of results which concerns all the companies of the group. This contractual mode is indeed very reassuring: if the savings are not up to the expectations, a system of penalties is activated.
