Upgrades included exterior insulation, air sealing, window and door replacements, roof membrane renewal, solar hot water preheating, and a gas absorption heat pump system for space heating and domestic hot water. The mechanical scope also incorporated heat recovery ventilators (HRVs), smart thermostats, and a building automation system (BAS) that brought the full mechanical system together under integrated controls. The project also enhanced the building’s appearance with new entry canopies, updated exterior materials and colors, and air conditioning ports integrated through the enclosure to support future cooling needs. Construction was completed while the building remained occupied, requiring careful planning and coordination with residents and trades throughout.
RDH provided Building Enclosure Consulting, Energy & Climate Consulting, Architectural Design, Structural Engineering, Cost Estimating, Tendering Support, Construction Administration, Field Review Services, and Indoor Environmental Quality (IEQ) Monitoring. The team assessed existing conditions, developed an integrated retrofit strategy, and completed modeling to evaluate building performance improvements. The enclosure upgrades improved thermal performance and air barrier continuity, with detailing at balconies, overhangs, and other transition conditions coordinated closely with the mechanical retrofit scope. Structural engineering supported the new entry canopies, cladding attachment, and roof upgrades required to accommodate rooftop mechanical equipment. RDH also supported IEQ monitoring and building performance monitoring before and after construction to help evaluate retrofit effectiveness and assess performance outcomes. The team’s involvement continued through implementation, including budget development, tendering support, construction administration, and field review services.
