Back to all projects
The Well in downtown Toronto was a 3.1 M sf mixed-use development spread over 7.8 acres. The design includes 1.1 M sf of office, 500,000 sf of retail and food services, and 1,700 residential units spread throughout six buildings connected to a 3-level retail base.
Engineering Link had been retained to evaluate the thermal bridging effects through the typical metal panel assembly at plenums, ramp walls, and soffits at various buildings and through the typical terra cotta wall assembly at the lower 6-storey portion of one of the buildings. The objective of the analysis was to calculate the overall effective R-value of the proposed exterior wall assemblies.
The thermal modeling was performed using HEAT3, which is a three-dimensional, transient, and steady-state heat transfer analysis program which is validated against standard EN ISO 10211. HEAT3 was used to evaluate the thermal bridging effects of the clips and continuous girt on the wall assembly.
