Mantle Climate has prepared comprehensive reports comparing whole-life carbon performance across multiple precast concrete building systems and Canadian climates. The analysis examines three scenarios: a precast envelope with a cast-in-place (CIP) structure, a precast envelope and floor system with a steel frame, and a total precast building. These configurations are evaluated across five cities—Vancouver, Edmonton, Toronto, Montreal, and Halifax.

The reports assess both embodied carbon (from material production, transportation, and construction/assembly) and operational carbon (from building energy use such as heating, cooling, and ventilation). It follows a full life cycle approach aligned with the National Whole-Building LCA Practitioner’s Guide, covering stages A1–A5 (product and construction), B1–B5 (use phase), and C1–C4 (end-of-life).

Overall, the reports provide a comparative understanding of how different building systems influence total carbon emissions over a building’s lifetime in varying Canadian climates.
