Bill > H4477

This bill requires newly constructed and substantially remodeled or rehabilitated buildings in Massachusetts to use electricity instead of fossil fuels for space heating and cooling, cooking, clothes drying, and hot water (including for pools and spas), with some exceptions. It also sets emissions standards for new or substantially remodeled biolabs and hospitals, requiring them to achieve net-zero carbon dioxide equivalent (CO2e) emissions by 2050. The bill empowers municipalities to adopt their own reporting and emissions reduction requirements for existing hospitals, biolabs, and other facilities. The Department of Energy Resources can grant waivers from the requirements in certain cases, and municipalities can impose penalties for violations of the law, which takes effect on January 1, 2023.
