Introduced Text

Massachusetts H3580 mandates new space cooling technologies in homes to be dual-purpose and integrated into thermostat-controlled systems.

Massachusetts H3580 updates the state building code to require all new space cooling technologies in single-, two-, and three-family homes to be capable of both heating and cooling, integrated into a thermostat-controlled system. This ensures cost-effective heating and continuous access to safe, reliable, and affordable thermal energy services. The bill also defines "non-emitting thermal energy" as heating or heating and cooling from fuel sources that do not emit greenhouse gases.
