RDH was engaged by FBM Architecture to provide building enclosure consulting for the design and early construction phases. The building’s coastal setting shaped the enclosure strategy from the outset. The team selected a highly insulated double-wythe precast concrete system for its durability, constructability, and design expression. The inner wythes are left exposed on the interior, providing a durable, low-maintenance finish that contributes to the building’s architectural character.
RDH worked closely with FBM Architecture to develop detailing for the precast wall panels, window interfaces, and air and water control systems. The enclosure strategy incorporated drained dual-stage sealant joints, window interfaces with drained sub-sill flashings, and continuous interior air seals to manage moisture risks in the waterfront environment. RDH also reviewed the precast supplier’s shop drawings during early construction to confirm alignment with design intent and performance objectives.
The results reflect the rigor of that approach. Whole-building airtightness testing at completion measured 0.136 cfm/ft² at 75 Pa, approximately half the maximum air leakage permitted under NECB 2020. The building is fully electric and designed to perform reliably in a coastal climate over the long term.
