Saint-Gobain Glass and Hydro Building Systems are joining forces to drive decarbonisation by helping the building industry design sustainable façades that have circularity built in. The two companies are leading the way through the use of low embodied carbon products thanks to a high percentage of recycled materials: specifically, the Saint-Gobain Glass ORAÉ® glass substrate and Hydro Building Systems aluminium façade products manufactured from Hydro CIRCAL® 75R.
Saint-Gobain Glass and Hydro Building Systems promote low carbon facades
Introduced in September 2022, ORAÉ® is the world’s first low-carbon glass on the market. According to its EPD, ORAÉ® has a verified carbon footprint value of 6.64kg CO2 eq./m² (for a 4mm substrate), a reduction of 42% compared to the Saint-Gobain Glass European baseline clear glass. This has been achieved through the use of renewable electricity and a recycled content of 64%.
Hydro CIRCAL® 75R, first launched in 2019, is a prime quality aluminium made with a minimum of 75% recycled post-consumer scrap aluminium. Hydro CIRCAL® 75R has a carbon footprint among the lowest in the world: 2.3 kg CO2 /kg of aluminium.
With a shared dedication to sustainable development, Saint-Gobain Glass and Hydro Building Systems, which includes the TECHNAL, WICONA, SAPA, and DOMAL brands, as well as recently acquired HUECK, are committed to helping developers and specifiers create more sustainable, lower embodied carbon buildings.
Buildings are currently responsible for 39% of global greenhouse gas emissions: the materials and construction of buildings accounts for 11% of all embodied carbon emissions, with a further 28% from operational building emissions (for heating, cooling, and power).
According to an official life cycle assessment study of façades, it is estimated that the embodied carbon of the building façade could be reduced by up to half by combining façade systems made from Hydro CIRCAL® 75R glazed with ORAÉ® products, such as the COOL-LITE® XTREME ORAÉ® solar control glass.
In addition, due to stringent emission regulations and the simple fact that the reserves of resources are slowly but surely being exhausted, the world’s interest in urban mining is increasing.
Saint-Gobain Glass and Hydro Building Systems are separately investing in developing urban mining partnerships throughout Europe, in line with their circularity approach. Each company has implemented initiatives to collect and recycle end-of-life aluminium and glass, thus fostering circularity.
Working in this direction, it is both companies’ ambition to continue developing partnerships with other stakeholders, deepen their research to develop increasingly sustainable products, and keep on leading the way by acting beyond regulations.
