GLASS FOR FACADE 2022

GLASS FOR FAÇADE - EDITION 2022 - 9 8 - GLASS FOR FAÇADE - EDITION 2022 In September 2022, Saint-Gobain Glass took a major step towards decarbonising the glass industry by announcing the commercial launch of ORAÉ®, the world’s first low carbon glass. By committing to its innovative spirit and continuous pursuit of sustainability, Saint- Gobain Glass has successfully reduced the carbon footprint of its clear glass substrate without compromising on the technical, quality or aesthetic performance of its products. A third-party confirmation of ORAÉ®’s environmental performance In April 2023, a new significant step has been taken forward: ORAÉ® has now a verified EPD, that confirms ORAÉ® as the glass with the world’s lowest carbon footprint, setting a new standard at 6.64 kg CO 2 eq./m 2 (from Cradle-to- Grave, for a 4mm substrate), a reduction of 42% compared to the Saint-Gobain Glass European baseline for clear glass. AnEPD is anEnvironmental Product Declaration, a third-party verified document that indicates the environmental impact of a product during its life cycle. The remarkably high content of external cullet in ORAÉ® production made it possible to reach an official recycled content of 64% according to ISO 14021. Saint-Gobain Glass is also applying for a Cradle to Cradle certification, with assessment expected in 2023. COOL-LITE® XTREME ORAÉ® in the product range for low carbon façades Saint-Gobain Glass has integrated the new low carbon glass substrate ORAÉ® in its portfolio of solutions. The aim is to combine this innovation with the most advanced coating technologies in terms of energy efficiency. This will help drastically reduce greenhouse gas emissions caused by cooling, heating and lighting when using a building. COOL-LITE® XTREME ORAÉ® is indeed a perfect match of performance and sustainability, reducing both operational and embodied carbon in buildings’ façades. A 2022 study conducted in partnership with the 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 1 . Real Estate pioneers leading the way towards more sustainable constructions As a sign of the market’s enthusiasm for this major innovation, several major real estate partners have chosen Saint-Gobain Glass to reduce the carbon footprint of some of their pioneer projects. This attests to the key role that ORAÉ® plays towards a more sustainable industry and in accelerating the development of the circular and low carbon economy. ORAÉ® now available in Calumen® to help calculating the footprint of projects Thanks to the detailed environmental data now available, ORAÉ® is integrated in Calumen®, Saint-Gobain’s all-in-one glazing digital configurationtool,tofacilitatetheunderstanding of ORAÉ®’s footprint and boost sustainability in construction. Building professionals, regardless of their level of expertise, can now evaluate the impact of ORAÉ® on the carbon footprint of their architectural projects. A window to the future COOL-LITE® XTREME ORAÉ® is a first step towards an expanded low carbon offer. These achievements are in line with Saint-Gobain’s commitment to reach carbon neutrality by 2050 and ambition to be the worldwide leader in light and sustainable construction.
