An efficient and responsible Group Maximize the contribution for the planet and communities

Climate scenario analysis at 2050 2.1.2.2 For strategic planning purposes, Saint-Gobain has built three qualitative climate scenarios that incorporate political, technological, economic and societal assumptions. Each scenario is associated with an increase in average temperature of between 1.5°C and 4.8°C before the end of the century. These scenarios help Business Units and the countries in which the Group operates to anticipate the impacts of climate change on their markets and their activities.

BUILDINGS AND ARCHITECTURE Buildings are generally collective buildings built around 2018 in accordance with the latest environmental regulations. ■ Household appliances are shared and efficient while excess heat is shared between connected buildings. ■ Apartments are easy to reconfigure and refurbish to optimize space. ■ Builders favor natural lighting, passive cooling and solar protection. ■ To improve their resilience, the buildings are equipped with green walls and roofs, wastewater and rainwater harvesting systems, ■ reflective materials, and the foundations are adapted to remove clays. The use of bio-sourced, reused and recycled materials is becoming widespread to mitigate the effects of climate change. Likewise, ■ energy self-production, waste sorting and composting systems are installed: innovations are thus used to optimize energy efficiency. The installation of smart meters and sensors makes it possible to monitor consumption and automatically regulate lighting, ventilation, ■ cooling and heating.
