Massachusetts H3529 establishes building energy and decarbonization standards for large buildings and creates a funding program for energy retrofits.

Massachusetts H3529 amends Chapter 25A to set annual carbon intensity limits for large buildings, aligning with emissions limits established in Chapter 21N. The Department of Public Utilities will promulgate regulations for compliance, including alternative methods.
