How does a curtain wall system contribute to LEED and green building certification?

Curtain wall systems can play a significant role in achieving LEED or regionally equivalent certifications in the Middle East (such as Estidama or Al Sa’fat) by contributing to credits in energy efficiency, daylight, materials and indoor environmental quality. Energy performance is the most direct contribution: specifying low-U, low-E insulated glazing, thermal breaks in frames, and solar-control coatings reduces cooling loads and helps meet energy-performance thresholds required for certification. Daylight optimization strategies—combined with glare control (frits, shading) and automated lighting controls—support credits for daylight access and reduced artificial lighting demand. Selecting recycled or locally sourced aluminum, and using low-VOC sealants and adhesives during fabrication, supports materials and indoor environmental quality credits. A properly commissioned curtain wall (including thermal and air leakage testing) feeds into the building commissioning credit by demonstrating actual performance versus modeled targets. In Gulf projects, façade choices that reduce peak cooling demand also contribute to district-level sustainability by lowering overall energy intensity. As a curtain wall manufacturer, we provide performance data, test reports and materials documentation to support certification workflows, and collaborate with design teams to tune glazing and shading strategies to the client’s LEED/Estidama goals.
