Municipal Opt-in Specialized Energy Code

Annual Town Meeting 2023 Action on New Energy Code

Annual Town Meeting 2023 adopted the  Municipal Opt-in Specialized Energy Code (Opt-in Code). Opt-in Specialized Code adoption is an action in Wellesley's  Climate Action Plan. The Code will benefit Wellesley because it: 

  • Is a necessary step toward achieving net zero greenhouse gas emissions by 2050, a goal shared by the State of Massachusetts and federal government.
  • Encourages electrification and avoids costly retrofits by requiring new buildings that are not all-electric to prewire for future electrification. 
  • Offsets GHG emissions by requiring solar installation for some mixed-fuel projects (i.e., buildings with combustion equipment designed for fossil fuel use).
