Project Overview

Five-storey mixed-use office building with four underground parking levels. Our scope covered Part 3 building energy modeling to demonstrate BC Energy Step Code 2 compliance for office, retail, and childcare occupancies.

The IES-VE 2023 model applied the weighted-average method across occupancies (per CoV EMG V2) and a separate NECB Part 8 reference for the childcare occupancy. Results: TEUI ≈ 127.6 and TEDI ≈ 34.6 (overall); childcare vs NECB: TEDI ≈ 82.3 (target =114) and TEUI ≈ 256 (target =342).

Our Contribution

  • Whole-building energy modeling Weighted-average method across occupancies; NECB reference for childcare.
  • Compliance analysis Verified Step Code 2 targets with detailed TEDI/TEUI reporting.
  • Childcare modeling (NECB Part 8) Built separate NECB reference and proposed models for the childcare occupancy.
  • Permit documentation Prepared complete Part 3 energy modeling package for submission.
