An Act relative to better buildings

This bill creates a new Better Buildings Act within Massachusetts law to set energy performance standards for large buildings, defined as those with at least 20,000 square feet. The Department of Energy Resources will establish rules requiring these buildings to meet specific limits on energy use and greenhouse gas emissions by 2050, with interim targets set every five years starting in 2025. Owners of these buildings must report their annual energy consumption, and the department will make this data publicly available. The standards will apply to various building types and occupancies, with the department having the authority to define subcategories and adjust thresholds as needed.
