Back in 2018, EQ wrote an article titled ‘TGS v3 – How do MURBs stack up?’. Starting January 1, 2020, all archetype buildings must comply with the TGS v3 absolute targets and meet Tier 1 at a minimum. Prior to this, compliance modelling was done primarily as a ‘reference percentage better than’ approach, which is still the case for the Ontario Building Code and many other certifications. In continuing this series, as we are now 2 years in to TGS v3, EQ has conducted a technical analysis on business-as-usual multi-unit residential building (MURB) design in a new-age building code.
