POSITIVE SOCIAL AND SOCIETAL IMPACT Lighter construction does not mean reducing the comfort level and performance of the building, particularly in terms of energy efficiency. On the contrary, this approach allows access to decent, comfortable housing for the greatest possible number. In North America, light construction is THE solution to the huge demand for affordable housing. In Türkiye, this construction method has proved essential for rapid rebuilding after the earthquakes of 2023, and building with lighter structures that would have less serious consequences in the event of another collapse. Lastly, this approach facilitates the move towards more adaptable and reversible buildings, meeting the challenges of urban flexibility and changing needs and lifestyles. This is an undeniable advantage when it comes to the end-of-life of buildings, as they can be easily dismantled and then reused elsewhere or recycled. A CONSTANTLY EVOLVING CONSTRUCTION METHOD Light construction is constantly evolving in line with the innovative solutions that make it up, with ever-lower carbon in materials such as concrete, plasterboard, glazing and glass wool made from alternative components, recycled materials, and through use of alternative energies. Renewable energy (photovoltaic panels), natural ventilation and heat recovery are also increasingly part of light construction projects. Lastly, BIM (Building Information Modeling) and AI optimize the use of materials and the energy efficiency of buildings. All these innovations will increasingly contribute to positioning lightweight construction as the indispensable construction method. Lighter load-bearing structures, in the form of timber skeletons, make it possible to combine reduced carbon footprint of buildings, speed of construction, and living comfort. © Roberto Sorin 29
