RDH was engaged by FBM Architecture to provide building enclosure consulting for the vie-story, waterfront residence, supporting design and early construction phases. Located in a coastal environment, the building incorporates a highly insulated double-wythe precast concrete enclosure selected for its durability, constructability, and design expression. The inner wythes of the precast wall panels are exposed on the building’s interior, providing a durable, low-maintenance finish and contributing to the space’s architectural character.
RDH worked with the design team to develop detailing for the precast wall panels, window interfaces, and air and water control systems, enhancing airtightness, moisture management, and long-term performance. 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 has a fully electric heating system.
Working closely with FBM Architecture during the design phase, the team developed an enclosure strategy to support airtightness, water management, and thermal performance. The approach incorporated drained dual-stage sealant joints, window interfaces with drained sub-sill flashings, and continuous interior air seals to mitigate moisture risks in the waterfront setting. During early construction, RDH reviewed the precast supplier’s shop drawings to confirm alignment with the design intent and performance objectives.
The use of precast concrete panels contributed to an efficient construction timeline while providing a durable, low-maintenance enclosure well-suited to the waterfront location and campus program. The project provides high-quality student housing, including accessible accommodation, designed to perform reliably in a coastal climate and to provide affordable housing for students.
