11 East Lenox is the first ground-up mass timber structure in the City of Boston, demonstrating a sustainably sourced carbon-neutral alternative to concrete and steel mid/high-rise construction. It is also in the first wave of Passive House Certified multi-family residential buildings in the City of Boston. In meeting Passive House building criteria, performance will far exceed the more prescriptive Massachusetts Stretch Energy Code and LEED building requirements, with energy consumption that is nearly 10% of that of typical new construction. Embodied Carbon Reductions in Mass Timber are significant, which are 844 metric tons of CO2 stored in timber; and 327 metric tons of CO2 offset by utilizing mass timber in lieu of concrete or steel Carbon sequestering structural frame with lower embodied carbon footprint. Other embodied carbon reductions include upcycled/ reused rigid foam insulation; recycled glass aggregate sub-slab insulation; overstock brick cladding. The project will offer a quiet, comfortable living environment, high indoor air quality, energy efficiency, and reduced utility costs for tenants.
