The Lauriau / Gaillard co-ownership is engaged in an ambitious architectural and energy renovation project ensuring a thermal improvement of the building envelope (insulation of the facades, collective replacement of the joinery, insulation of the floor on the basement) accompanied by a renovation of energy systems, in particular ventilation of dwellings.
The co-ownership was supported by various service providers (local energy agency MVE, ARC, prime contractor PAZIAUD, support for financing ENERGY PULSE) for the definition of a project to meet the needs of the local authorities. maintenance of its heritage while significantly improving energy consumption. This support (initial assessment, global architectural and energy audit, customized design of the project, consultation of the companies) allowed after two years of study a unanimous vote of the works during an extraordinary general assembly.
Thanks to the incentives of the public authorities within the framework of the call for project "sustainable co-ownership", the project has deepened various environmental aspects of a renovation: feasibility study for the use of biosourced materials in thermal insulation of collective buildings of housing, life cycle analysis (global carbon impact) of the proposed variants of materials.
