Building Controls
Johnson Controls Digital Building Automation System (BAS) network:
Metasys System with PC–based monitoring, both local and remote access. This system provides real-time monitoring with automatic remote notification of critical system messages.
HVAC
Central Cooling Plant:
1550-ton total capacity. (2) York 425-ton centrifugal chillers and (1) York 450-ton centrifugal chiller. (2) Trane 125-ton screw chillers (one air-cooled). 68°F water condenser is provided by (3) wells through plate/frame heat exchangers. Well system has a capacity of up to 2700/gpm. Full redundancies exist for total system.
Central Boiler Plant:
(5) Byron 15-lb steam water tube boilers. 5250 MBH capacity each. Typical winter operation requires two boilers to be online. Boilers are all dual fuel capable (gas and oil). Boiler facility includes walk-in underground tank vault housing 40,000 gallons of fuel oil.
Air Handlers:
(10) digitally-controlled variable air volume systems serve all office spaces. Units provide both temperature and humidity control. Individual thermostats control office space temperatures.
Electrical Services
Main Service:
5500 KVA with dual primary commercial power feeders. Automatic transfer switching provides changeover of loads in the event of the primary power feeder loss. The campus has underground redundant feeders with multiple tie switches, upgraded high voltage breakers and electrical usage/demand monitored in real-time through the BAS.
Substations:
Southwest Wing: (2) 2000 KVA 13.8 KV 480/277 3ph
North Wing: (2) 1000 KVA 13.8 KV 480/277 3ph
All substations have redundant primary and secondary tie switches. All electrical gear is comprised of Square D or S&C components. Motor control centers and variable frequency speed drives are Allen Bradley. All electrical gear is protected with a minimum of two levels of transient surge protection.
Emergency Power:
300 KW Caterpillar emergency generator
Lighting & Plumbing
All office space is served by very flexible power and data distribution systems. These systems feature vertical distribution closets with fiber optic backbone, and UPS power along with ample space for data switching equipment. All tenant space features horizontal distribution via floor duct system with intermediate distribution stations.
Lighting
