- Outdoor air flush-out was conducted on a phase-by-phase basis to improve the Indoor Air Quality (IAQ) prior to occupancy
- 75% of the construction waste is diverted from landfill
- Achieved 25% Light Power Density (LPD) reduction with no compromise to Citi’s lux level requirements by including wattage saving from the Digital Addressable Lighting Interface (DALI) lighting system with settings-based space usage during the commissioning stage
- HVAC systems installed in line with the efficiency requirements outlined in the Advanced Buildings Core Performance Guide
- The project space meets appropriate Zoning and Controls of the HVAC system
