Building lighter, an approach that has become crucial Unlike traditional construction, which relies on heavy materials such as concrete or brick, lightweight construction favors lighter load-bearing structures in the form of timber, metal or concrete “skeletons”, to which non-load-bearing façade and partition systems are attached. This makes it an appropriate and sustainable solution for reducing the carbon footprint of buildings, while meeting the demands of cost, speed and comfort. SIGNIFICANT REDUCTION IN THE ENVIRONMENTAL FOOTPRINT By reducing the use of heavy, carbon-intensive materials, lightweight construction limits the extraction of natural resources and energy consumption, thus avoiding CO2 emissions and promoting circularity. In addition, off-site construction of all or part of the building results in less waste and disruption on the construction site. AN ECONOMICAL AND EFFICIENT SOLUTION But beyond its ecological advantages, light construction provides an effective response to budgetary and time constraints. The lightness of the materials allows for simpler foundations, cuts construction times and reduces costs. Off-site construction can represent a time-saving of up to 30% compared with conventional methods. Innovative solutions shake up established construction methods. Lightweight construction is thus emerging as a sustainable, efficient alternative to traditional techniques, in constant renewal through technological advances and new design methods. SPOTLIGHT 28
