LUCENT TECHNOLOGIES
Miramir, FL

Architect: Veenendaal Cave Inc.
Location: Miramar, Florida
Project Size: 229,000 square feet
Construction Cost: $140 Million
Systems Commissioned: HVAC, Central Plant, Electrical, Emergency Power, UPS systems, Fire Protection, and Failure Mode Testing

The Lucent Technologies Miramar, Florida facility is a 4-story, 229,000 square foot computer research and development complex. The mixed-use structure contains office spaces, laboratories, computer rooms, UPS rooms, mechanical rooms, a fitness center and a full service kitchen. Mechanical and electrical systems were designed for full redundancy and fail-safe operation. High-density computer racks were arranged in hot aisle/cold aisle configuration. Leibert overhead cooling systems were installed to cool the aisles in addition to the conventional underfloor systems.

KLG Jones provided full commissioning services, including design review, commissioning specifications, construction inspection, pre-commissioning checklists, functional performance testing and failure mode testing for all critical systems, owner’s training and system documentation. Systems commissioned included the central plant with water cooled centrifugal chillers, cooling towers, boilers, emergency generators, UPS systems, electrical distribution, Liebert computer room air-conditioning systems, air-handling units, DDC control system, pre-action fire protection systems, lighting and VAV systems serving the office areas.

UNC AT CHAPEL HILL
INFORMATION TECHNOLOGY BUILDING
University of North Carolina at Chapel Hill, NC



Architect: Hartman-Cox Architects
Location: Chapel Hill, North Carolina
Project Size: 98,000 square feet
Construction Cost: $40 Million
Systems Commissioned: HVAC, Emergency Power, UPS, Lightning, Power Distribution / PDUs, Liebert XDP/XDO units, Chilled & Hot Water and CRAC Units

KLG Jones provided full commissioning services for the new Information Technology Building at the University of North Carolina at Chapel Hill. The project consists of a 5-story building containing offices and mechanical and electrical spaces required to support the main campus computing facility. The machine floor is designed with cooling capacity and power distribution to support a load of 250 Watts/square foot.

Air-conditioning is provided by a combination of chilled water CRAC units supplying air to the underfloor air distribution system and Liebert XDO/XDP units located overhead in the cold aisles. Perforated floor tiles supply air to the lower level racks, and the XDO units cool the upper level server racks. The facility is mission critical for the University and contains a number of redundant systems to increase reliability. Redundant capacity is provided in the air-conditioning system. Power is fed to the building from two separate substations. An emergency generator and a three-section UPS system provide emergency back up power. One section of the UPS is redundant with two sections able to carry the load for 20 minutes. Chilled water and steam are supplied from the campus distribution systems, which have multiple central plants connected to the loops.

KLG Jones provided full commissioning services including full integrated load bank testing of the machine floor and support systems, functional testing of all mechanical, electrical and emergency power systems, failure mode testing of all redundant systems and thermal imaging of battery connections, electrical panels, PDUs and mechanical equipment.
