Project, solution, service and innovation for Sibca

The projects and solutions presented by the local authority of French Guiana are part of a comprehensive low-carbon strategy, covering the entire building life cycle: construction, operation and end-of-life phases. The projects make the most of local bio-sourced materials (Guyanese wood, compressed earth bricks, coconut fibre, bamboo), reducing the carbon footprint associated with transport and integrating a circular economy approach. The buildings are designed according to bioclimatic principles: optimal orientation, natural ventilation, air fans (financed via CEE/ADEME schemes), night-time over-ventilation, solar shading and passive insulation. The operating phase benefits from an energy mix in transition to 100% renewable by 2027, which drastically reduces indirect emissions linked to usage. The projects are backed by environmental standards currently being structured: NF Habitat HQE and the future Bâtiment durable Guyane label (co-developed with ADEME), inspired by BBCA and incorporating carbon indicators adapted to the equatorial context. Modular prefabrication is also being promoted to reduce construction site nuisance and impact in tropical environments. These projects are linked to the Regional Plan for Adaptation to Climate Change ("Overheated Cities" section) and are part of the NPRU, OIN and LCA initiatives on a regional scale.
