Run and standby secondary chilled-water pumps with variable-frequency drives (vfd's) and two-way valves keep pumping costs low. Fiberglass cooling towers are used to resist the aggressive ocean fog climate. The custom AHUs have full outside air economizer controls, and they supply a total of 222,000 cfm to the building. Two boilers provide heat to the building, one sized at 1,600 MBtuh output and the other sized at 4,000 MBtuh output.
A 15,000-gal water storage tank is provided along with diesel and electric fire pumps, combination stand pipes, and full sprinkler systems. High-rise stair pressurization, vestibule ventilation, and atrium exhaust systems on emergency power are included. Double containment fuel oil storage with duplex pumps in the garage feed the roof-mounted emergency generator and day tank. Domestic water booster pumps, gas-fired domestic water heaters, medical and control air compressors, and medical vacuum pumps round out this highly serviced building.
