Switzerland/France: Along with its partner Batica, LafargeHolcim is optimising the design of a low-carbon house, bringing together the latest innovations developed by the group's global research and development centre in Lyon, France.

Construction of the House of Tomorrow began at the end of October 2020 in Saint-Caprais-de-Bordeaux, Gironde. The materials used for its construction will have a CO₂ footprint more than 40% lower than a traditional house, and an optimised energy performance. The integration of these innovations in the house has made it possible for such a property to remain financially accessible to buyers thanks to controlled costs.

To achieve low CO₂ emissions performance, LafargeHolcim used its innovative cement and concrete products, all of which are available on the French market. Foundations were poured using ECOPact AA concrete, with emissions 80% lower than standard concrete. ECOPact A concrete, with CO₂ emissions 50-70% lower than standard concrete, will be used for the compression slab of the VS floor (crawl space). Airium, an insulating mineral foam, will be used to insulate the walls. A very low density concrete – 40-300kg/m³ depending on the mix – Airium represents an environmentally friendly, healthy and affordable insulation solution. LafargeHolcim’s Agilia Chape Thermic fluid screed will be used to coat the under-floor heating elements.
