Description
We worked with the network appliance team and Devcon Construction (General Contractor) to design and build this 14,000 square foot state-of-the-art high density rack lab/data center while the building was occupied. This unique lab space utilizes a "contained cold isle" design concept and was custom-built to reside on the 1st floor of an existing 3-story building. It is NetApps largest "in-house" rack lab/data center in the United States and boasts capacity for over 720 8KW server racks (lab equipment design cooling capacity = 410 watts / sq. ft.). The innovative energy efficient system and mechanical cooling infrastructure for this center takes advantage of unique environmental design conditions. The lab can operate on 100% air-side economizer for up to 80% of the calendar year. Along with full air-side economizer capabilities, the lab is served by an "n+1" 2360-ton central chiller plant with variable-speed primary pumps, high-efficiency centrifugal chillers and counter-flow cooling towers. $1 M+ PG&E Rebate.
Project award was based on our combined technical engineering solutions associated with the HVAC and building automation/controls design. Our MEP and BAS departments worked in concert to design and implement custom air handling equipment, air and water distribution systems, chiller plant systems and sequencing, and air-side economizer/relief systems. We performed certified startup and balance services and assisted in 3rd-party commissioning activities as required to deliver a complete and fully tested, validated and integrated high density rack lab environment.
To promote energy efficiency, we provided many “Green” Solutions to this project, specifically:
- Air Side Economizers
- ALC DDC Controls
- High Efficiency Water Cooled Chillers
- Variable Speed Pumping
