Building Envelope Assessment
| Location: |
Toronto, Ontario |
| Description: |
High-Rise Condominium |
| Problems & Issues: |
Various concerns including reports of moisture ingress, air drafts, condensation at exterior glazing assemblies and complaints of odour transference between Suites prompted a comprehensive review of the exterior walls, glazing assemblies and central ventilation systems at the high-rise condominium. |
| Building Solutions: |
The investigation consisted of a series of visual inspections at the building exterior and interior that were performed over a period ranging from September 2010 to March 2011. The exterior masonry investigation was complemented by a detailed review at the south elevation by means of suspended access. Additional investigations in the form of a thermal infrared survey, window performance testing, blower door testing and an air-balancing performance review were performed to supplement the investigation.
The field investigation revealed a number of concern areas related to safety, performance, operation and aesthetics. A comprehensive remedial program addressing air leakage, masonry repairs, glazing performance and mechanical system optimization was developed and presented to Building Management and the Condominium Board of Directors. |
