How is energy efficiency boosting the ecological transition?

Energy savings are one of the priority objectives in the fight against global warming and for the energy transition. Buildings alone account for 35 % of global energy consumption and 39 % of carbon dioxide emissions.

Making the construction sector more sustainable is a crucial issue for achieving the goals of the Paris Agreement: if implemented globally, energy efficiency measures in the construction sector could reduce CO emissions by 5.8 Gt by 2050; that is an 83 % reduction in greenhouse gas emissions. How can these goals be achieved?

This can be achieved, for example, through a "fabric first" approach, i.e., a design that maximizes the performance, particularly energy performance, of the components and materials that make up the building from the outset. This approach is advocated by Saint-Gobain.

By developing low emissivity glazing and high-performance insulation solutions with highly recycled or biobased materials that significantly reduce heat transfer between the inside and the outside, Saint-Gobain is contributing to the design of new buildings with minimal energy requirements for heating and cooling.

At the same time, Saint-Gobain advocates the development of a more respectful building site. To this end, we are creating materials that can respond to eleven structural stages in the life of a building site in order to improve the final energy efficiency of the latter. Lightweight glass panel partitions, double flow ventilation systems, waste sorting and reuse... The nature of the materials, whether they are circular or designed for their energy efficiency, promotes sustainable construction.
