Massachusetts has seen a rapid adoption of its new specialized stretch code, aimed at reducing fossil fuel usage in new buildings. Introduced a year and a half ago, this optional code has been embraced by 45 municipalities, covering around 30% of the state’s population. The law became active in 2023, reflecting the state’s ongoing leadership in decarbonizing the built environment. Now, 33 communities have implemented the code, with 12 more set to follow within a year.
The state’s first stretch code, created in 2009, laid the groundwork by setting stringent energy efficiency requirements. As of June, only 8.5% of residents lived without this code. This new specialized stretch code aims to target emissions reductions from 2025 to 2050, aligning with Massachusetts’ goal to become carbon-neutral. In 2021, the state legislature mandated the creation of this new code to approach near net-zero carbon emissions in new constructions.
Net-Zero Buildings Initiative
The specialized stretch code doesn’t mandate immediate net-zero emissions but ensures new buildings are prepared for future carbon-neutrality. There are multiple compliance pathways, including full electrification or partial use of fossil fuels paired with higher energy efficiency standards and solar panel installations. Homes must be wired for electric vehicle charging stations, and larger buildings must meet Passive House standards to significantly reduce energy usage.
The quick adoption by cities like Boston, Worcester, and Cambridge has encouraged decarbonization advocates. Many municipalities have voted nearly unanimously to adopt the code, with more expected to follow. Emphasizing the code as a consumer protection measure, rather than a burden, has been key to its acceptance. State and federal incentives also help offset initial construction costs, ensuring lower operational expenses for residents.
Industry Concerns
However, not everyone is convinced. The construction industry has voiced concerns about the increased upfront costs and supply chain issues. According to Emerson Clauss III from the Home Builders and Remodelers Association of Massachusetts, the equipment needed to meet the code’s standards is pricier than anticipated. With Massachusetts having high electricity costs, there’s also worry about near-term financial implications for homeowners who opt for all-electric homes.
Builders are facing challenges adapting to multiple codes, including the basic code, the previous stretch code, and the new specialized code. Moreover, confusion persists among municipal building directors, though efforts in cities like Cambridge, which was an early adopter, have shown that proactive communication and training can smooth the transition. Assistant Commissioner of Inspectional Services, Jacob Lazzara, highlighted that while initial confusion existed, time and clear communication have helped ease the adoption process.
Massachusetts’ new specialized stretch code is a significant step towards carbon-neutrality, balancing environmental goals with industry challenges. The rapid adoption by numerous municipalities demonstrates a growing commitment to sustainable building practices. While the construction industry faces legitimate concerns about costs and adaptation, the long-term benefits of reduced energy expenses and improved living conditions present a compelling case for the code. Future efforts should focus on communication and support to ease the transition for all stakeholders involved.
