City of Sunnyvale, CA, USA

Design Guidelines for Bird-Safe Buildings (Voluntary) 

  • These guidelines attempt to consider multiple projects and solutions to challenges imposed by each of them, with the goal to:

    • “maximize readily visible differentiations of material, texture, color, opacity or other features to fragment glass reflections and reduce overall transparency from ground level to 60 feet up, including the possible use of etched, fritted and opaque-patterned glass.”

    • Designs should favour low-reflective materials, glazing, and angles that reduce reflections, i.e. transparent walls that merge together, glass on rooftops, greenery or foliage inside buildings, and spotlights.

  • The Planning Commission recommended that the City work with other environmental groups to monitor design effectiveness to further develop programs and solutions.
