In addition, the hemp used comes from hemp farms in Ile-de-France.

The first Crédit Agricole Immobilier Corporate et Promotion project to integrate the industrial innovation of WALL'UP Préfa, "Be Fine" responds to energy, environmental, health and comfort imperatives by relying on a hemp agricultural sector with high production potential. growth. France is the European leader in hemp production, and the 3rd in the world. In 2025, future residents will benefit from energy-efficient, better-insulated housing, allowing them to reduce their energy expenses:

• 160.000 kg of hemp concrete will be used for the 4.600 m2 of facade walls of the “Be Fine” program, which represents: 10.000 kg of CO2 emitted, whereas with conventional concrete, this would have represented the emission of 188.000 kg of CO2, a saving of 178.000 kg of CO2.

The challenge of off-site construction

In addition to integrating WALL'UP Préfa prefabricated walls into its construction, the “Be Fine” program will be built off-site. Concretely, this involves prefabricating the facades of the homes in the factory which will then be assembled on the site. The choice of this method of construction has several advantages which are to reduce the duration of construction sites significantly, to overcome climatic hazards, to combat the arduousness of construction sites and finally to limit the nuisance for local residents during construction. The carbon footprint of off-site construction is around 40% lower than a traditional construction site due to the reduction in the number of journeys and waste, combined with the use of bio-sourced materials.

For Franck Hélary, Managing Director of Crédit Agricole Immobilier Corporate and Promotion: “To meet the challenges of carbon neutrality 2050, and the new RE2020 regulations, hemp backed by an off-site approach is one of the solutions for building more responsibly and sustainably. A biosourced construction material with many advantages in meeting the requirements of construction in terms of energy, environmental, health and comfort performance, hemp relies on a sector of the local economy with strong growth potential. This program is a perfect illustration of the Crédit Agricole group's desire to support its customers and society in their energy transition and its ability to develop local solutions with local stakeholders. »
