Massachusetts has updated it's building codes with a strengthened Stretch Code that goes into effect in 2023 - and introduced a new Specialized Opt-In Code that communities can begin opting into as soon as 2023 as well. These codes will require lower HERS scores and, for some buildings, Passive House certification. In this Lunch & Learn session, we will provide a Passive House 101 crash course for those new to the concept - and then discuss how it fits into the new building codes. This session is ideal for city councilors, town meeting members, city planners, building inspectors, code officials, zoning boards, and community advocates.    Read More
