Energy-intensive building

This project won the Grand Prize of the jury of the Trophées Bâtiments Circulaires 2023 in the “Public project owners – tertiary buildings” category.

Rehabilitation of an abandoned commercial wasteland into a Social and Solidarity Economy (SSE) Centre with the use of reused materials (radiators, sanitary facilities, doors, lighting, parquet flooring and rainwater recovery system). Soil unleasing with the creation of a landscaped valley and installation of 300 photovoltaic panels for a power of 1000Kva/year.

Building users opinion

Satisfied. The project was undertaken with the future tenants.

If you had to do it again?

Reused materials pose constraints related to regulations, insurance and supplies.

The parallel creation of the Plateau Circulaire in Caen made it possible to secure the materials, restore them if necessary and focus on the finishing work (radiators, sanitary facilities and doors), which are easier to insure.

The establishment of a cross-cutting “reuse” criterion and batch no°1 dedicated to reuse was relevant, as was the support of an Assistance to the Contracting Authority specialised on the subject.

Circular economy strategy

    Project stage

    • Maximization of the number of impacted batches

    Depending on the feasibility study and resource diagnosis.

    Integration of the reuse specifically in the special technical specifications of the concerned batches

    Yes

    Resource diagnosis
    Feasibility study

    No

Reuse : same function or different function

    • Structural framework
    • Indoor joineries
    • Raised floors
    • Electricity
    • Plumbing
    • others...

    • 50 cast iron radiators (origin: Plateau Circulaire, Colombelles);
    • 30 lights (origin: Plateau Circulaire, Colombelles);
    • 20 doors (origin: Plateau Circulaire, Colombelles);
    • 15 toilets (origin: Plateau Circulaire, Colombelles);
    • 1 rainwater recovery system (origin: Hérouville-St-Clair);
    • 1 existing wooden floor has been preserved;
    • All the existing metal framework has been preserved.

    The cast iron radiators, doors and sanitary facilities were recovered and refurbished at the Plateau Circulaire in Colombelles. They were transported and implemented by Le Wip, holder of the reuse batch.

Logistics

    No

    • No problem of storage, supply correlated to the progress of the works

Insurance
