Saint-Gobain France, en partenariat avec Arcora, a présenté une nouvelle étude réalisée avec Actierra, portant sur la performance des façades intégrant les vitrages à contrôle solaire COOL-LITE®, à l'occasion du Zak World of Façades Paris. Cette recherche répond aux enjeux des bâtiments tertiaires, éducatifs et collectifs face au réchauffement climatique, à des attentes accrues en matière de confort des usagers et au cadre réglementaire exigeant de la RE2020 en France.
Which glazing to combine with dynamic solar shading for comfort & environmental quality At Zak World of Façades Paris, Saint-Gobain Glass introduced a new study conducted in partnership with ARCORA, assessing the impact of façades integrating our COOL-LITE® solar control glazing solutions. In a context where tertiary, educational and collective buildings must respond to global warming, growing user comfort expectations, and stricter regulations like RE2020 in France, well-devised solar protection solutions are now essential to addressing those issues effectively. The study hence sets out to identify high-performance, sustainable façade solutions – especially high selective solar control glazing- that can: - Adapt to evolving climate conditions, - Reduce dependence on blinds, - Optimise natural light and views, - Ensure thermal efficiency and low carbon impact. To do so, the study relies on comprehensive parametric analyses, including: - RE2020 performance assessments, - dynamic thermal and daylight simulations, - and a life cycle analysis aligned with French standards. A wide range of parameters were explored, such as building orientation, climate scenarios, glazing types and ratios, and solar shading strategies. A rigorous scientific methodology was applied to ensure the reliability and relevance of the results. The full results will be unveiled very soon—but one could already highlight one clear conclusion : a combination of solar control glazing with high-performance interior blinds outperforms traditional setups using Low-E glass with external blinds. The result? Improved thermal performances, greater robustness, enhanced visual comfort and reduced carbon footprint impact. This work reinforces our commitment to designing façades that are not only high-performing but also environmentally responsible! Pascal PINET Richard Christophe Catherine VAUTRIN Géraldine Caro
