A5.107.1 Required elevation treatment. Building elevation treatment shall incorporate bird-friendly mitigation strategies. No less than 90 percent of a building elevation, measured from grade to a height of 40 feet (12 m) above grade, or from grade to the height of an adjacent mature tree canopy (whichever is greater), shall incorporate bird-friendly mitigation strategies. No less than 60 percent of building elevation, 40 feet (12 m) above grade to the top of the building elevation, shall incorporate bird-friendly mitigation strategies.
Strategies to minimize the risk of birds colliding with buildings:
1. Glazing. Glazing with visual markers shall include, but is not limited to, the following:
a. Etched or fritted glass with patterns of elements on the exterior having minimum dimensions of 1/4” (0.64 cm) diameter for dots or 1/8” (0.32 cm) width for stripes in a density of 2 inches (5.1 cm) maximum horizontally and vertically (the “2 x 2 Rule”). Note: If the visual markers are on glass surface 2, they can be effective if visible behind an exterior surface with reflectivity of 15 percent or less.
b. Interior or eExterior glazing film with 2 x 2 visual markers.
