Hingham has joined a growing number of Massachusetts communities in adopting the Specialized Energy Code, a measure aimed at reducing greenhouse gas emissions in new buildings. Town Meeting voters approved Article 39, which amends the town's general bylaws to incorporate the new state standards for energy efficiency in new construction projects.

Brad Moyer, Chair of the Hingham Climate Action Commission, explained that the code applies only to new construction, not renovations or additions. It provides builders with two pathways to compliance. The first is an all-electric path, which uses technologies like heat pumps for heating and cooling and has no additional requirements beyond the current "stretch code" already in place in Hingham. The second is a mixed-fuel path, which allows for fossil fuel systems but requires the building to be pre-wired for future electric conversion and to have on-site renewable energy, typically solar panels, to offset carbon emissions.

During the discussion, residents questioned the potential costs for homeowners. Moyer cited state estimates that pre-wiring could add up to $9,000 and solar panels around $22,000 for a 4,000-square-foot home, though rebates and incentives could lower the net cost. Resident Eileen Calnan raised concerns that the bylaw's language appeared to apply to existing buildings, but Moyer clarified that the underlying state law limits the specialized code to new construction only. The measure passed by a strong majority, making Hingham the 49th municipality in the state to adopt the code.
