The “Comprehensive Building Decarbonization” legislation – Bill 13-22 – will ensure that all-electric building standards become part of the County’s building code no later than the end of 2026, with limited exceptions for hospitals and other facilities needing emergency backup systems or high-energy industrial or commercial cooking facilities.
In a state – Maryland – committed to a carbon-free electrical grid in coming years, the Montgomery County bill guarantees that almost all new buildings will be equipped with electric hot water systems and heat pumps for space heating and cooling, creating a zero-greenhouse gas (GHG) emissions future. Typically for an urban jurisdiction, buildings account for more than 50% of Montgomery County’s total carbon emissions.
