See below how Glass facade & windows by Saint-Gobain can contribute to LEED V4.0 criteria: Building life-cycle impact reduction.
To encourage adaptive reuse and optimize the environmental performance of products and materials.
Option 1 “Historic building reuse”: (5 points)
Maintain the existing building structure, envelope, and interior nonstructural elements of a historic building or contributing building in a historic district.
Option 2 “Renovation of abandoned or blighted building”: (5 points)
Maintain at least 50%, by surface area, of the existing building structure, enclosure, and interior structural elements for buildings that meet local criteria of abandoned or are considered blight.
Option 3 “Building and material reuse” (2–4 points)
Reuse or salvage building materials from off site or on site.
Option 4 “Whole-building life-cycle assessment”: (3 points)
For new construction (buildings or portions of buildings), conduct a life-cycle assessment of the project’s structure and enclosure that demonstrates a minimum of 10% reduction, compared with a baseline building. No impact category assessed as part of the life-cycle assessment may increase by more than 5% compared with the baseline building.

To make the full life cycle assessment (LCA) of a building, data at product level is necessary. In line with its commitment to green building, Saint-Gobain Glass assesses the environmental impact of all its product ranges thanks to LCA (cradle to gate), and provides a significant number of Environmental Product Declarations (EPDs) compliant with international standards, covering 20 product families and more than 200 glazing configurations. The results of these assessments allow us to optimize the environmental performance of our products and materials, while also constituting the first step in conducting the LCA of the building.
