Concerning the design and operation of buildings to protect birds.

SB 6272 requires Washington buildings to turn off nonessential lighting during April, May, September, and October - peak bird migration months - to reduce collisions caused by light pollution. It also establishes incentives within the state's LEED building certification program to promote bird-safe features like specialized glass that prevents collisions. The law aims to protect Washington's over 500 bird species, which support ecosystems through pollination and habitat engineering, while simultaneously reducing energy consumption. These provisions apply to both new and existing buildings and are designed to balance wildlife conservation with energy efficiency.
