Clean Buildings Performance Standard (CBPS)

Clean buildings are essential to meeting our state energy goals. In 2019 the Clean Buildings bill was signed into law, expanded in 2022, and augmented in 2023. The objective is to lower costs and pollution from fossil fuel consumption in the state’s existing covered buildings, multifamily buildings, and campus district energy systems. The law also provides Tier 1 and Tier 2 incentives to encourage building owners to make energy efficiency improvements earlier than required.
