IKEA Centennial is the first U.S. IKEA store to integrate a geothermal system. This technology involves drilling 130 holes – each 5.5 inches wide and 500 feet deep – into the earth for pipes holding heat-transferring liquid circulating through underground loops to either warm-up or cool-down the temperature inside the store. All of this equates to the one of the largest geothermal systems in the U.S.

In addition, the facility has a 60,000 sf solar array consisting of a 498-kW system, built with 2,212 photovoltaic panels, and will produce approximately 740,000 kWh of electricity annually for the store, the equivalent to reducing 586 tons of carbon dioxide (CO2).

The project was completed approximately 3.5 months early.

Network Appliance Building 1
This 165,000-SF cold shell building was converted to a warm shell, followed by the completion of 125,000 SF of interior space. Interior environments included approximately 40,000 SF of R&D laboratory, training facilities, an executive briefing center as well as open office/systems furniture plan for global support personnel.

Network Appliance RTP Building 2
The next phase of expansion involves the conversion of a cold shell office building to a warm shell state, fitting out approximately 150,000 SF to accommodate customer support, product development, software development and laboratory/data center business unit expansion needs.

Network Appliance Dedicated Lab – RTP Building 4
This dedicated lab facility contains over 2,100 racks of data equipment, with the lab environment designed at over 650 watts per square foot. Over 11,000 tons of cooling capacity is delivered by four (4) 2,800 ton centrifugal chillers served by 8 cooling towers. Chilled water runs through the coils of eighty (80) 45,000 CFM air handling units which deliver a collective 3.6 million CFM to the laboratory environment. The structural steel frame is clad in architectural metal panels with weather-proof relief air louvers surrounding almost the entire 3rd level, dedicated solely to the air handling equipment and half of the electrical distribution gear.

Located across from the Dobbins Air Field, special precautions were taken to reduce outside noise infiltration. Triple-glazed Trainer glass out of Chicago was used to achieve maximum noise reduction.

Redundant N+1 MEP systems increase reliability and ensure the building is always fully operating.
