Sustainability Highlights

Criteria Achievement
Energy EfficiencyAchieved 50.7% energy cost savings after final review recalculations, with proposed annual electricity consumption of 2,537,718 kWh/year.
Renewable EnergyAchieved 38.9% renewable energy contribution by cost after final review recalculation.
Water Conservation49.82% reduction in potable water use through water-efficient fixtures and fittings.
Outdoor Water ConservationAchieved a 100% reduction from the baseline for outdoor irrigation through the reduced irrigation strategy.
Indoor Water ConservationAchieved a 55.19% reduction in water use through the usage-based indoor water-use calculation.
Water MeteringImplemented building-level water metering and water metering to support monitoring and management of water consumption.
Rainwater Management
Achieved the full documented Rainwater Management credit through the percentile rain-event management approach.
Heat Island Reduction
Achieved the documented Heat Island Reduction strategy covering both nonroof and roof measures.
Sustainable TransportationAchieved Access to Quality Transit, supported by 238 weekday trips and 172 weekend trips, and also achieved the Reduced Parking Footprint credit.
Parking ReductionThe final review documentation reported a 95.81% reduction in parking capacity under the documented compliance approach.
