The main building’s mechanical systems consist of five (5) 4-pipe variable volume modular air handling units. The system utilizes shut-off type variable air volume terminal units with hot water reheat at the zone level. The chilled water system consists of an air-cooled screw chiller nominal size of 120 cooling tons which will deliver 42 deg. F water to the rooftop units. The hot water system consists of two fully redundant 1,000 MBH output natural gas-fired condensing boilers. The boilers will deliver 140 deg. F to the rooftop units and variable air volume terminal units.
The SRO suites mechanical system, located on part of the first floor and the entire second floor, consists of an air-cooled heat recovery variable refrigerant flow (VRF) system. The individual suites have a ceiling cassette type VRF fan coil units with individual control. The ventilation air for the VRF system is via a single gas-fired packaged 100% Dedicated Outside Air System with energy recovery.
Each rooftop unit has high efficiency filtration media (MERV 13) to comply with ASHRAE 90.1 as well as bipolar ionization to aid in cleaning the air delivered to the facility. The individual VRF ceiling cassette units also have bipolar ionization.
