Network Appliance B2 Rack Lab & Central Plant
Project Location:
1275 Crossman Avenue, Sunnyvale, CA
Owner:
Network Appliance
Contractor:
Devcon Construction
Scope of Services:
Design/Build HVAC, Mechanical, Electrical, Plumbing (MEP) systems, and Building Automation System (BAS) expansion/upgrade as required to support new 14,000 sq. ft. high-density rack lab/data center. Green building project.
Description
ASI worked with the Network Appliance Team and Devcon Construction (General Contractor) to design and build this 14,000 sq. ft. state-of-the-art, high-density rack lab/data center while the building was occupied. This unique HD rack lab space utilizes a "contained cold isle" design concept and was custom built to reside on the first floor of an existing three-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 rack lab/data 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" 2,360-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 as commercial HVAC contractors associated with the HVAC and building automation/controls design. ASI's 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.
ASI performed certified startup and balance services and assisted in third-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 building project, specifically:
- Air Side Economizers
- ALC DDC Controls
- High-Efficiency Water Cooled Chillers
- Variable Speed Pumping
Condenser Water System
Cooling Towers
Custom Data Center Air Handler
