The condominium is located in downtown Montreuil (Paris suburb) in the heart of an urban renewal project. This is a building built in 1973, the last renovation was in 1987. It includes 53 homes and a carpentry workshop.
The thermal rehabilitation of the two buildings, built with non-insulated concrete framed facades and single-glazed metal frames, is part of a process begun several years ago: insulation of roof-terraces in 2004, renovation of the boiler room in 2010 with the installation of 2 cascading natural gas condensing boilers, lighting of the common areas by LEDs realized in 2012.
A shared Global Audit was conducted during the 2013/2014 heating season, highlighting the opportunity for a global and ambitious energy renovation.
The work program includes:
- The energy treatment of the building envelope : Renovation of the facades with thermal insulation from the outside, replacement of joinery, shutters and insulation of the boxes, insulation on the underside of the low floor;
- Improvement of energy systems : Implementation of a humidity-sensitive ventilation and installation of automatic balancing valves on the heating network;
- Compliance and treatment of building pathologies : Resumption of balcony and joinery guardrails, securing of roof terraces, installation of smoke-control skylights enslaved, installation of a liquid waterproofing and treatment of the nose of balconies.
All this by following a green building charter , in compliance with environmental standards: Access, cleanliness, safety, limitation of nuisances (noise, dust), waste management and sorting.
This co-ownership has been awarded the call for projects ADEME Île-de-France region "sustainable condominium". In this context the co-ownership wanted to commit to a responsible project:
- Comparative study of biosourced solutions for the insulation of façades and low floors
- Analysis of the recyclability of the materials used
- Carbon analysis of the renovation project (and its variants) on the perimeter of the works and the operation of the buildings on the principle of life cycle analysis

Sustainable development approach of the project owner
The buildings achieve a level of energy performance "Building Low Consumption" (Cep <104 kWh / m².year) with a complete treatment of the building envelope completed by the improvement of the air quality of the building (implementation work of humidity-controlled mechanical ventilation). The condominium is committed to a responsible approach by studying biosourced alternatives for thermal insulation work in front (wood wool) and floor (cork panels). The entire project was also the subject of a life cycle analysis adapted to the rehabilitation process taking into account the overall carbon footprint of the various construction solutions. The co-ownership also wanted the implementation of a green building charter to limit the impact of the renovation project on the environment during the construction site. Accompanied by different service providers, the co-ownership has put in place an important dynamic of consultation during all the duration of the project:
- Shared global audit: poster campaign, questionnaires, call for participation group "works", information meetings (technical, grants and subsidies, final project), housing visits, work meetings, dissemination of a summary.
- Conception Mastery of work: courier joinery with possibility of individual meeting, visits housing, meetings working group, communication panels architectural project, meeting financing, diffusion of a technical summary, permanences financing, presentation final offers, realization of financing plans individualized.
- Execution of the works: application of the green building charter containing a communication / works part in a busy environment (grievance book, identification of the person involved, planning, etc.)
The condominium consists of two adjoining residential buildings, forming an angle between the street Clotilde Gaillard and Gaston Lauriau in Montreuil. The immediate environment of the co-ownership is very heterogeneous. In front of building B is a 5-storey office building with contemporary architectural treatment (curtain wall, stone cladding). In front of the building A are small individual houses in masonry running with plaster and roof tile red terracotta.The facade treatment project aims to upgrade the building in its environment while maintaining its identity. The initial architectural choices went to a uniform white coating on all facades with a delimitation of volumes by a discrete salmon coating (arrows balconies, acroteria). The project aims to enhance the diversity of facades and volumes of the condominium. The identity of buildings A and B is marked by a different color choice on both buildings while maintaining common touches reminiscent of the uniqueness of the residence.
