After a thorough process of research and deliberation, BostonCAN is excited to announce the focus of our next campaign: winning policy change to accelerate the conversion of Boston’s existing 86,000 buildings to clean energy for heat, cooling, lights, and all their energy needs.
Powering our homes and businesses with fossil fuels accounts for about 70% of our collective greenhouse gas emissions. The Carbon Free Boston report calls for “deep energy retrofits” within 30 years of all existing buildings in the city: installing deeper insulation in walls and roofs with heating and cooling supplied by highly efficient electrical heat pumps. As our grid becomes steadily greener, these heat pump systems will be responsible for fewer and fewer greenhouse gas emissions.
Our top near-term goal is to strengthen the energy efficiency of Boston’s largest buildings. Less than 3% of Boston’s buildings account for more than half of all greenhouse gas emissions from buildings. These largest buildings are already regulated by Boston’s Building Energy Reporting and Disclosure Ordinance (BERDO), which covers all buildings of 35,000 square feet and larger. Adding stronger enforcement mechanisms to BERDO will lead property owners to transition more quickly to cleaner energy. More retrofits will also lead to more jobs for Boston residents, as well as cleaner air, soil and water as we reduce our need to transport and combust fossil fuels.
Retrofitting existing buildings is one of the four top priorities that Boston has chosen for the update of its Climate Action Plan. Carbon Free Boston emphasized the importance of reducing carbon use in existing buildings, especially since “85 percent of projected building square footage in Boston in 2050 exists today.”
The goal is challenging. Many Boston buildings face barriers to even basic levels of insulation, let alone the deep energy retrofits they will need. Judy Kolligian, a BostonCAN member and landlord, has already upgraded heating systems for her own and her tenants’ apartments. “I’ve been improving my building as quickly as I learn how to, but my home has asbestos siding and my tenants’ has asphalt siding. I need the City and Mass Save to figure out more cost-effective ways to insulate buildings like these.”
BsotonCAN invites you to join our “Green Buildings, Not Greenhouse Gases” campaign, working with allies and city leaders to find urgent, equitable, and affordable solutions for retrofitting all buildings, from triple-deckers like Judy’s to the biggest buildings in the city.
