ORAÉ has an estimated carbon footprint of only 7 kg CO2 eq./m2 (for a 4mm substrate), a reduction of approximately 40% compared to Saint-Gobain Glass European baseline clear glass.

Saint-Gobain Glass is integrating the new low carbon glass substrate ORAÉ in its portfolio of solutions, starting with COOL-LITE XTREME solar control glass.

COOL-LITE XTREME was chosen as the first ORAÉ application thanks to its advanced coating technology, which drastically reduces greenhouse gas emissions caused by cooling, heating and lighting when using the building.

COOL-LITE XTREME ORAÉ is a perfect match of performance and sustainability, reducing both operational and embodied carbon.

A 2022 study conducted by Saint-Gobain Glass in partnership with Engineering consulting firm Arup revealed the importance of considering and acting upon these two parameters jointly in order to shrink the carbon footprint of buildings.

In every project for which COOL-LITE XTREME ORAÉ is selected, ORAÉ substrate will be available for all panes composing the insulating glazing units.

In order to ensure timely and reliable supplies of ORAÉ low carbon glass, production campaigns were carried out in three countries: France, Spain and Germany.

An opportunity for the construction sector

The building industry currently accounts for almost 40% of global greenhouse gas emissions and is at the heart of the decarbonisation challenge.

Furthermore, according to the aforementioned joint study with Arup, façades represent up to 20% of a building's embodied carbon.

By working on the overall impact of glass, we can achieve a significant reduction in the carbon footprint of buildings, while continuing to provide the essential benefits of natural light and thermal comfort for the occupants.

This confirms the key role that ORAÉ will play in promoting a sustainable industry and accelerating the development of the circular and low carbon economy.

Three major real estate partners – Bouygues Immobilier, Icade Santé and Nexity – have already committed to using COOL-LITE XTREME ORAÉ glass in their projects.

Bouygues Immobilier will implement it on its office building operation “Kalifornia” (Hauts-de-Seine, France).

Icade Santé will install it on the “Le Parc Polyclinic” operated by the Elsan group in Caen (Calvados, France), while Nexity will use it on the “Carré Invalides” rehabilitation project (Paris, France)
