The new McNutt Data Center located on the campus of the University of North Carolina at Greensboro in Greensboro, North Carolina, USA, was commissioned by KLG Jones using full integrated systems testing methodology.

The HVAC system for the building consists of a Trane chilled water air handling unit serving a VAV air distribution system for the support area and four air-cooled Data-Aire Computer Room Air Conditioning units serving the data center. One Data-Aire unit is redundant. Campus chilled water and steam are utilized to provide cooling and heating to the air handling unit and a steam to hot water heat exchanger for the reheat coils.

The Electrical system for the building includes a 1500 kVA pad mounted transformer supplying normal power to the building. An 800kW Kohler diesel powered generator with a 36-hour base mounted fuel tank provides standby and emergency power to the UPS and selected building and life safety loads. A Liebert UPS system consists of two 400 kVA/320 kW units supplying uninterruptible power to the data center busway system and UPS panelboards that serve the Service Operation Center (SOC), the Building Distribution Frame (BDF), the Core Distribution Frame (CDF) and mechanical controls.

The entire electrical system is designed parallel redundant down to the UPS panel level, however, a construction decision removed the ability to switch between UPS sources at the panel level which could leave half the busways and UPS panels without uninterruptible power upon failure of a UPS. A load bus synchronizer has been installed between the UPS’s, and plans include the future installation of static switches to address the issue.

KLG Jones provided full integrated systems testing of the HVAC, electrical (normal and emergency) power systems including UPS, and building automation control system. KLG Jones provided load banks to simulate full load conditions and coordinated all testing. KLG Jones provided full analysis of the testing real-time and initially the testing did not pass. The IST was repeated after confirmation of HVAC repairs and the system passed.
