One of the building’s innovative features is its recycled water system. The building’s plumbing system is designed to harvest rainwater and recycled gray water for use in non-potable applications, such as irrigation and flushing of toilets. This system lowers the facility’s demand for treated water from the local utility.
“In California, there is a focus on water reduction and demand,” said Jesse Eisenhart, WSP project manager. “For a facility like the Chase Center, it’s a tremendous asset to have the ability to recycle water, rather than use potable water, whenever possible.”
The recycled water system will enable the arena to achieve a high level of water efficiency, conserving natural resources and reducing energy required for domestic service water heating.
The building features several sustainable features intended to far exceed code compliance. It incorporated efficient LED lighting fixtures throughout the interior of the
Building, and meters were installed to monitor energy and water use. Light-colored material was used on the roof to reflect, rather than absorb, solar heat, reducing the building’s “heat island” effect.
The HVAC system features four large bowl air handlers with direct expansion and indirect and direct evaporative cooling. The Chase Center also employs a heat pump chiller and heat recovery loop to transfer heat efficiently dependent on thermal comfort demands. The system also features six condensing boilers, cooling towers, water source heat pumps, local variable refrigerant flow systems. The HVAC system and the building envelope was designed to exceed the “Thermal Environmental Conditions for Human Occupancy” requirements as outlined by ASHRAE Standard 55-2004.
“WSP facilitated communication and collaboration between the contractors, engineers, and facility staff who worked on these various systems to enable them to reach a higher level of quality than what would otherwise have been possible,” Eisenhart said.
The Chase Center includes a 950-space parking garage that will be primarily used by employees of the facility and VIP guests. Most visitors will use public transportation to arrive at the event.
To encourage alternative transportation use, the arena offers 300 spaces for valet bicycle parking, a service provided by the San Francisco Bicycle Coalition that has been provided at many city events over the past 25 years.
