Scalable Solutions to Triple Decker Retrofits

Triple-decker homes, built in the late 19th and early 20th centuries to house immigrant workers, are an important New England housing resource. However, their energy performance is typically poor: they are often leaky, under-insulated, and heated with outdated fossil fuel systems. In this session, three organizations will describe scalable, replicable models to upgrade these iconic buildings. ABCD, which retrofits triple-deckers that house low-income individuals, will present on cost and energy savings achieved and challenges encountered. Placetailor, Boston's leader in passive house and energy positive development, design, and construction, will present their visionary approaches to market-rate triple-decker retrofits. And Fraunhofer CMI will describe an innovative panelized construction method that could revolutionize low-rise multi-family retrofits. MassCEC’s Galen Nelson, who led Boston’s Triple Decker initiative, will moderate.
