WATER CONSERVATION

One of the most significant accomplishments of this project includes the water efficiency measures implemented to reduce overall usage and consumption.

Water use by tenants and visitors to the building has been reduced by more than 46% through the use of highly efficient fixtures in bathrooms. Use of these fixtures saves more than 4.3 million gallons of potable water from being flushed!

Approximately 25 million gallons of water per year are required for the HVAC system in a building of this size. Approximately 95% of the contaminated ground water is being captured and treated to supply 100% of the water required for HVAC systems to cool the building and 100% of needed water from on-site sources, avoiding the purchase of this water from the city, thereby reducing the demand on city infrastructure.
