Data Centers Projects

ATS has worked on data centers for large, nationally known companies in Puget Sound, Quincy, WA;  San Antonio, Texas; Chicago, IL, Forest City, N.C.; Altoona, IA, Prineville, OR and Lulea, Sweden.  We are experts at maintaining uptime, critical monitoring of electrical systems, Evaporative Cooling Systems and standard Chilled Water Systems.  We have also performed numerous retrofits of smaller data centers and gateways to increase energy efficiency.

Wenatchee Data Center

Location: Wenatchee, WA

Eastridge Case Study SavingsCooling the Data Center

Located in central Washington state, Wenatchee is known for its apples, wide-open spaces, and its abundance of activities for outdoor recreation. The area is also well suited for locating mission critical data centers. The vast open landscapes, mild dry climate, and low power rate from hydropower attract many high-tech firms needing to locate off-site data centers. The mild climate allows for “free cooling” by utilizing air-side economizers to cool the data center with outside air instead of mechanical cooling for much of the year. However, this “free cooling” only works when data center sequences and safeguards allow the equipment to utilize it.

Facility staff at an international communication company’s Wenatchee data center realized they were not taking advantage of “free cooling” strategies once they began reviewing data from the ATS facilityCARE ongoing commissioning and advanced analytics service.

ATS installed the control system at the data center in 2008 utilizing the sequences specified during construction. The original sequences focused on loading the plant and letting it run, which resulted in chillers operating more hours than needed. In addition, over time, system modifications and one-off changes created conflicting overrides of the economizers. As a result, the economizers were not open during times with optimal “free cooling” conditions. The facility was not fully utilizing outside air for cooling, resulting in increased utility cost and unneeded equipment runtime.

Free Cooling Enabled

In 2015 ATS implemented facilityCARE, an ongoing commissioning and advanced analytics service to track equipment usage and highlight opportunities for operational improvement at the data center. SkySpark (www.skyfoundry.com) is used in the ongoing ATS facilityCARE service that includes monthly reviews and analysis by ATS engineers. As part of a facilityCARE review, ATS verified what facility operators had long suspected — the economizers were not functioning optimally. Using historical site data, ATS developed an estimate of savings based on the requirement that the facility use outside air for cooling when available. With data to back up the proposed changes, ATS was contracted to implement an energy conservation measure (ECM) to modify the economizer sequences so they function when outside air conditions are optimal for cooling. Without the facilityCARE service, this issue may have gone unaddressed since the plant appeared to be operating smoothly, experiencing no temperature issues and the facility engineers were focused on more immediate concerns.

Air-Side Economizer Savings

ATS implemented the updated economizer sequences in the fall of 2017. Now that the sequences are in place the data center has seen impressive savings over the first two months of operation. Over December 2017 and January 2018, the data center saw $22,500 in avoided cost for their data halls. Utilizing a baseline for comparison, the data center is expected to see a 24% reduction or 5.2 million kWh usage drop. The facility is also expected to save $137,000 in avoided utility cost over the first year of operations.

Wheeler Data Center (Dept. of Information Services)

Client: State of Washington
Location: Olympia, WA
Architect: NBBJ
General Contractor: Howard S. Wright
Mechanical Contractor: University Mechanical

Approximately 461, 000 sq. ft. 63/20 financed project consisting of two office buildings to house the headquarters for the Washington State Department of Information Systems, as well as a new state data center that allows the state to consolidate older data centers into one efficient location.  Project features include: ~30, 000 sq. ft. of white space. Ultimate build is ~60, 000 sq. ft. of white space; 4.5 MW critical load. 9.0 MW ultimate build-out; Cooling system is air handlers with air-side economizer, direct evaporative cooling, and chilled water; Chiller plant uses high-efficiency variable-speed chillers and variable primary flow; UPS units have continuous-rated static switches, enabling 99% efficiency; ATS provided Alerton controls on all HVAC, water and electrical monitoring systems.

One Lab

Over 57, 000 square feet (including generator buildings, switch yard and mezzanine). The building’s cooling method uses outside air with evaporative coolers. Number of Pods: 48 Pods (8 Clusters of 6 pods) separated into two groups of 24 on either side of a central control/work area. ATS, as part of the project team, designed, built, and commissioned the Alerton controls for the innovative mechanical systems for this project. ATS provided Electrical System monitoring via a combination of MODBUS integration and hardwire interface to Electrical Gear.
