Energy-intensive building
  • BBC Effinergie label

The Transition-Centre must allow the social reintegration through housing. This operation consists of 20 one-room apartments, two of which are changeable in two-room apartments and also include common area (kitchen, living room, workshop, etc…) and offices.  It will be managed by UDAF Charente and supervised by social workers. The contractor of the operation is the Public Housing Office of Angoumois (OPH de l'Angoumois)

The deadline and energy efficiency goals led to choosing a design/execution solution for the construction and the Cluster Eco-Habitat advised the contractor on a cross-curricular methodology. The goal was to minimize the energy consumption but also to meet the specific uses of a transition-centre where tenants are both people who are in the process of social reintegration and social workers (housing/offices)

Therefore, the choice was to build housings that communicatewith one another and with the office area, while preserving spaces for privacy.

Architectural description

The Transition-Centre must allow the social reintegration through housing. This operation consists of 20 one-room apartments, two of which are changeable in two-room apartments and also include common area (kitchen, living room, workshop, etc…) and offices. It will be managed by UDAF Charente and supervised by social workers. The contractor of the operation is the Public Housing Office of Angoumois (OPH de l'Angoumois).

Adaptable housings
Most of the insertion housing concern single people, however UDAF wants to have the opportunity to accommodate others typologies. Two units have been created on the one-room apartment basis with the ability to expand into a two-room apartment by using a common area.

Easy Therm blocks:
The selected constructive system is a concrete block in Easy Therm compensated slate. This type of construction process belongs to the category of distributed insulation, which reduces thermal bridges and optimizes the thickness of opaque walls.
