Building Enclosure Performance Verification & Commissioning

For the Hurontario Light Rail Transit Maintenance & Storage Facility, Engineering Link provided building envelope commissioning services. The project scope included design review, field testing, and performance verification for glazing and wall panel assemblies.

The project involved constructing a new 730,000-square-foot hospital to replace the existing facility, targeting LEED® Silver certification or higher.

Engineering Link conducted extensive Building Envelope testing, including: Air Tightness Testing: Assessed the airtightness of window assemblies to ensure compliance with performance standards. Water Tightness Testing: Evaluated the windows’ resistance to water penetration under simulated environmental conditions.

George Brown College constructed a 10-storey building with a concrete foundation, steel core, and mass timber framing, integrated with the Daphne Cockwell Centre of Health Sciences.

Our testing focused on operable glazing units, curtain walls, solar chimneys, prefab joints, skylights, and façade junctions, complemented by infrared thermography to detect thermal inefficiencies.

This new 7-storey, 600,000 square-foot hospital, connected to a 145-bed long-term care facility, includes 164 beds and expanded cancer care services. Building envelope scope included 3D thermal modeling, drawing and glazing fabrication reviews, construction monitoring, performance verification testing, and LEED v4 Building Envelope Commissioning. 

Building envelope inspection and testing services for the Ken Soble Tower Passive House retrofit, Canada’s first project of its kind. The scope included air and water tightness testing, thermographic scanning, and adhesion testing of exterior sealants. The project achieved a high standard of airtightness, meeting Passive House Canada requirements and significantly reducing energy use.

Part of a 3.1 million square-foot mixed-use development, The Well spans 7.8 acres in downtown Toronto and includes office, retail, and residential across six towers connected by a 3-level retail podium. As part of the new construction design-assist team, our role focused on thermal performance analysis of exterior wall assemblies. Using 3D thermal modeling (HEAT3), we assessed thermal bridging through metal panel systems at plenums, ramp walls, and soffits, as well as terra cotta cladding on the six-storey podium.

Engineering Link provided building envelope engineering services for the new Canada Post GTA East Distribution Centre in Scarborough. The project involved using advanced thermal modeling tools to design a high-performance building envelope that reduces thermal bridging and air leakage, contributing to the facility’s net-zero carbon footprint and compliance with Tier 2 Toronto Green Standards. 

An investigation at SODO Residences, 620 10th Avenue SW, Calgary, addressed recurring condensation in the East Light Box, causing water leakage into commercial units below. Air leakage was identified as the primary issue, with repairs focused on sealing gaps in the light box enclosure and IMP joinery. Smoke testing confirmed significant improvements, though minor air leakage persisted. Additional sealing was completed, and repairs will be monitored through the next winter to ensure airtightness. 

Supporting the City of Calgary’s goal to reduce GHG emissions by 60% by 2030 and reach net zero by 2050 across 500+ facilities through feasibility studies identifying lifecycle upgrades and low-carbon solutions.

Work includes thermographic evaluations of envelopes and roofs, assessment of assemblies, windows, and doors, and applying NECB 2020 Thermal Bridge Modeling and ASHRAE standards to determine U- and R-values.

Infrared thermographic scans were performed on the exterior walls and roofs of 21 Melinda St., 25 King St. W., 30 Wellington St. W., and 199 Bay St. to identify thermal bridging and air leakage, following ASTM E1186-17 under pressurized and depressurized conditions.

Anomalies were documented, with recommendations for further investigation, glazing retrofits, and additional roof scans in warmer conditions to assess moisture issues. Findings and thermographic images were provided in detailed reports to guide remediation and improve thermal performance.
