The scope addressed the building’s aging exterior assemblies through a phased approach. Phase 1 focused on the building enclosure: windows were replaced with triple-glazed units with fiberglass frames, exterior insulation was added to exposed concrete walls and overclad with stucco and metal panels attached with fiberglass clips to minimize thermal bridging, and airtightness was improved through detailing at windows, doors, and penetrations. Phase 2 addressed mechanical upgrades. Energy Efficiency Measures were evaluated across both phases, with a cost-benefit analysis performed to assess the financial feasibility of each measure against predicted energy savings.
Phase 1 enclosure renewals were completed in nine months. The project was part of a research study with industry and government partners aimed at improving energy performance across the existing building stock and received the inaugural Technical Achievement Award from the Canada Green Building Council and SAB Magazine, and the Sustainability Award from APEGBC in 2013.
