Modulo-bois requalification process

The reduction of energy consumption and negative environmental impacts are a major ecological concern. The post-war buildings represent a large number of housing with a poor energy performance. This project proposed by the partnership team Ateliers Lion, Arcoba, Vinci Construction and France-Arbonis Construction concerns a global offer of the mass housing renovation. This concept deals with the thermal performance as well as the quality of use.

Nevertheless, the Modulo-bois process is widely adaptable in frame and in depth to every type of apartment building. It proposes an intervention on the pre-existing structure by removing the prefabricated facades and extending the building by adding wooden prefabricated three-dimensional modules. This scenario suggests a requalification, while maintaining the original spirit of the buildings. In fact, it is about “thickening the building’s skin” to answer all the deficiencies noticed today. This system concentrates on a methodological, effective and reproducible proposition to reach high environmental performances and architectural quality corresponding to tomorrow’s request, while keeping a realistic technical and economic feasibility.

We privileged the use of wood, a renewable material offering thermal and mechanical performances and allowing an effective process of prefabrication in term of implementation.

The aimed thermal performances match the low energy buildings: an objective of 40kWh/sqm/yr for heating and 10kWh/sqm/yr for water heating. The energy performance of the proposed method allows energy consumption to be divided by 4, and potentially a division by 5 of the energy bill.

Contrary to the demolition trend, the Modulo-bois process brings an architectural, constructive and urban solution to create a transformation, a diversification and an important densification of housing estate.
