ASHRAE/AEE Joint Summer Event - Aug 17

Tour the Evaporative Cooled
South Hill Data Center

Puget Sound Chapter ASHRAE and the Pacific Northwest Chapter of the Association of Energy Engineers (AEE) invite you to tour the South Hill Data Center. This project showcases the ultimate re-positioning of a building. A semi-conductor chip manufacturing facility converted to a full scale evaporative cooled data center with hot aisle containment. Built to LEED Gold and Energy Star quality standards, this facility features year-round economizing without the use of refrigerated cooling to serve a total critical design load of 14.7 megawatts.

The innovative design of this facility makes use of the (52) 50,000 cfm custom clean-pak AHUs originally intended to accommodate 56,600 SF of Clean Room manufacturing. The AHUs were upgraded to accommodate new evaporative media, mist eliminators, stainless drain pans, and new MERV-8 & 13 filters sections. A centralized evap-water distribution & collection system consists of two custom-built pumping skids which provide [(N+1) x 2] redundancy along with (2) 10,000-gal fiberglass holding tanks. A non-chemical water treatment system with blow-down controls, and side-stream filtration provides clean water for the evap-cooling and humidification.

The mechanical room has been converted into a mixed air plenum and provides year-around economizing without the use of any refrigerated cooling. Designed to cool a total critical load of 14.7 megawatts, rooftop louvered penthouses were added to provide for the 2.6 million cfm of outside air required. The building utilizes Hot Aisle Containment and Evap-Cooling.
