Project Overview

Twenty-five-storey mixed-use tower with three underground parking levels, advanced under Vancouver's Broadway Plan. The rezoning submission is under the Green and Resilient Building Measures Package (CD-1 Item 4.1) and aligns with the CoV Green Buildings Policy for Rezoning (last amended Nov 27, 2024).

The model (Athena IE 5.5) uses architectural take-offs, a 60-year life, and required scope (substructure and shell). Compliance values exclude biogenic carbon per CoV. Results: total GWP (A–C, excl. biogenic) ≈ 7,590,911 kg and intensity ≈ 340 kg CO2e/m². The design meets the current 400 kg benchmark and the anticipated 360 kg future target (F=0.9) for permits after mid-2025.

Our Contribution

  • Material take-offs and LCA modeling Quantified concrete and reinforcement from drawings; built Athena model to CoV scope.
  • Whole-building LCA and stage reporting Reported A1–A3, A4–A5, B2/B4/B6, C1–C4 in compliance format.
  • Rezoning documentation (ECDR) Prepared condensed/detailed tables, totals/intensity, and BoM for submission.
  • Compliance review and narrative Aligned with Broadway Plan rezoning and CoV embodied-carbon benchmarks.
