In 2019 Mayor Marty Walsh committed to making the City of Boston carbon neutral by 2050. In 2020 the City began developing regulations to neutralize the emissions of its building stock. Currently, all city-funded affordable housing is required to be zero net carbon (ZNC) with most if not all of its energy produced on-site. As of 2020 all new municipal buildings will be zero-net carbon, and in 2021 the City is expected to enact legislation that requires all new buildings over 50,000 GSF to demonstrate carbon neutrality. Amidst a boom in high EUI laboratory construction, the standards are putting the potential of a carbon-neutral future to the test. This session will include representatives from the City of Boston and the consulting engineers developing the standard.
