The Green Buildings Act and Green Buildings Advisory Committee (GBAC)

About the Rhode Island Green Buildings Act

On November 9, 2009, the Green Buildings Act (RIGL §37-24) was signed into law and was further updated on June 27, 2022. The Act requires that all new construction and renovation projects over 10,000 gross square feet, constructed by a public agency be designed and constructed to a LEED Certified or an equivalent high performance green building standard.

 A public agency includes all State departments, municipalities, public institutions of education, and any subdivisions of these agencies.

About the Rhode Island Green Buildings Advisory Committee

The Rhode Island Green Buildings Advisory Committee (GBAC) was formed in 2010 to help implement the Green Buildings Act. The Committee, which consists of volunteers from State agencies and the general public, works with the Department of Administration and the Rhode Island Building Code Commission to help ensure compliance with the law and to provide education on green building practices for Rhode Islanders.
