Context
France’s commitment to reducing its greenhouse gas emissions significantly by 2050 involves
the massive renovation of its existing housing stock. The French government is aiming to
renovate 500,000 dwellings per year. The key challenge associated with achieving this target
lies in the number of available jobs and the costs generated by complete restorations. It is
essential to reduce these costs by improving productivity and renovation processes on the one
hand, and by proposing global renovation solutions on the other, with the integration of
several functions into a single product.
Objectives
The mass-production of renovation solutions would seem to be a promising approach to such
problems. The CRIBA (Construction et rénovation industrialisées bois acier—Industrialised, Steel
and Timber-Based Construction and Renovation) project thus aims to:
Develop a mass-produced technical solution for the renovation of multi-dwelling buildings,
incorporating roofing and façade treatments, insulation, architectural improvements,
energy production and management
Develop a software suite that allows for the configuration of the technical renovation
solution according to the existing situation and the publication of all documents required
for the studies, production and installation of the panels
Lay the foundations of an industrial prefabrication chain for the components within a new
entity acting as the assembler (or coordinator) of the global renovation solution
Demonstrate the pertinence of the concept in an actual situation at the scale of a block of
buildings.
Implementation
The CRIBA project consists of the simultaneous execution of two works packages:
The first concerns the development of the technical solution for a prefabricated building
shell with timber framework, and the deployment of application tools, in particular a
façade configurator based on a digital mock-up. This package will allow for the
establishment of the product and service offering that will then be marketed
The second package concerns the renovation of the La Pince housing block at Saint-Paul-lès
-Dax. It comprises all of the studies required for the renovation of the block, with a view to
making this an exemplary and above all reproducible operation. The block consists of a
complex of five buildings with a total of 110 multi-unit social dwellings.

Expected results
Innovation
Innovative design of a prefabricated building shell product
specifically designed for renovation.
Simplification of methods for existing 3D surveys and their
enhancement with an innovative aerial survey service per-
formed by drones.
Design of a digital mock-up-based configurator for choosing
appropriate products, calculating renovation costs, launching
manufacturing and planning the installation of panels.
Organisation of a renovation logistics chain, capable of mass-
producing modules configured to suit the needs of particular
buildings.
Economic
The industrialisation of renovation sectors is a process that
shifts a proportion of the added value of projects towards
factories and also increases the qualification requirements for
installation teams. The move towards mass-production
principles, which the CRIBA project wishes to instil in the
renovation sector, will allow installation companies to trans-
form their trades, attract higher-qualified staff and increase
their profitability.
Environment and social
This project concerns multi-unit social housing stock built
between 1949 and 1974 (estimated at approximately 1.9 million
dwellings), which are amongst the most energy-intensive in
France. The average consumption of this type of dwelling is
between 200 and 350 kWhPE/m².an. Based on this initial
situation, CRIBA thermal renovations aim to achieve an energy
efficiency level of 25 kWhPE/m².year. This will allow for
significant energy savings and a reduction in CO2 emissions,
accompanied by greater comfort for users and a drop in energy
poverty.
Application and markets
The CRIBA concept developed in the project and demonstrated
in the La Pince housing block will be deployed by the Syrthea
company, which has been created for this purpose.
The target market will initially be the renovation of multi-unit
social housing built between 1949 and 1974, which are
considered to be the priority targets of renovation policies, with
an eventual target of 4,000 dwellings to be renovated per year.
In addition, Syrthea will also be targeting the private multi-unit
housing market.
