This ecological transition launched by the City of Paris requires close cooperation with stakeholders in the real estate sector. SaintGobain France, the City of Paris and the city’s landlords have joined forces to reduce the building industry’s environmental footprint: on the one hand by developing closed-loop recycling of building site waste (recycling window glazing and using it to make new, more sustainable windows) and on the other, by increasing the percentage of recycled content in construction solutions, particularly glass and plasterboard. PROFOUND CHANGES IN HEALTHCARE FACILITIES Bringing more flexibility into a sector shaped by numerous health and safety constraints to guarantee patient care under good conditions is no easy task. Healthcare establishments – whether old or new – must be redesigned to make them more modular, flexible and open. Climate change is another major challenge. Reducing CO2 emissions and being more sustainable and low-carbon should lead to buildings with an optimal design in terms of thermal properties, energy, carbon impact and summer comfort. All issues for which Saint-Gobain provides practical solutions to: • Take care of the design and construction quality of these buildings, in terms of thermal, acoustics and light, as well as air quality and hygiene; • Allowmodularity and adaptability of interior spaces; • Renovate and thereby reduce energy consumption and CO2 emissions. White paper on healthcare facilities (*). Guide tohealthcare infrastructure (*). STRATEGY ENERGY SAVINGS AT SCHOOLS Whether new or old, school buildings must also adapt to the climate emergency, as well as evolving to keep pace with new teaching methods. This dual challenge must take center stage in all construction and renovation projects for the 65,000 establishments in France today. To this end, the Group has carried out a comprehensive analysis of these growth markets, notably through the actions of SaintGobain Solutions France. This proactive approach has resulted in a white paper, Educational establishments: current and future challenges (*). The white paper addresses issues such as energy performance, designing the school of tomorrow, and improving comfort and quality of use for students and teachers. All issues for which Saint-Gobain provides practical solutions to: • Treat the building shell and its acoustics; • Improve indoor air quality; • Enhance lighting comfort; • Decarbonize at a competitive cost.
