SRP-MIC IT Data Center

SRP-MIC IT Data Center, Scottsdale AZ

Project Description:

The SRPMIC IT Data Center consisted of a single story building delivering 300 kVA of UPS Power to a 2,500 SF data floor.  The Data Center serves the Community’s government and municipal infrastructure.

Scope of Work:

TMCx was retained by SRPMIC to provide Level 5 Integrated Systems Commissioning services, including design and submittal reviews, associated with the Mechanical HVAC, Electrical, and Fire Protection Systems.  In addition to the commissioning services, TMCx provided additional training in our Building Engineering Systems Training (BEST), a 2 day on site, hands on, activity focused on problem solving and identifying root causes to operational issues.

Systems:

  • Mechanical HVAC systems (chilled water plant, computer room AC units, and exhaust systems) 
  • Electrical systems (emergency generator, transfer switches, UPS, and power distribution units)
  • Life safety (fire alarm and fire suppression systems).

Challenges and Successes

  • Issue: During functional testing, it became evident that there was an issue relating to UPS load and generator sizing. What was apparent was that under low UPS load, the leading power factor was causing the generator to shut down on a “loss of field” safety scenario.

          Resolution: After meetings with the design and construction teams, it was determined that the input filters installed on the UPS’s were causing the leading power factor, and removal of these devices would eliminate the issue. Once removed, testing continued without further issue.

  • Issue: During test and balance, it was found that design outside air requirements, as listed in the contract drawings, were not being met for the building. This was due to the lack of balancing dampers on the return air ducting and an incorrect damper location.

          Resolutions: a programming change was made to run the equipment at 50% design air instead of an “N plus One” scenario. While this did not increase the outside air, it was an acceptable solution to the Engineer of Record.
