LEED certification of public buildings.

Defines "public building" as a building used in the operation of state government, county government, or the government of a city, town, or township. Requires the office of management and budget to perform a cost benefit analysis to determine the potential overall savings that could be realized if all public buildings constructed after December 31, 2021, were built to attain at least silver LEED certification and if all public buildings in existence and use on January 1, 2022, were upgraded to meet at least silver LEED certification standards before January 1, 2024.
