HP Wynyard: White Racks Save Power

HP uses white cabinets to house the servers at its Wynyard data center, a design choice that can save energy, since the white surfaces reflect more light. This helps illuminate the serve room, allowing HP to use less intense lighting. Another energy-saving measure is the temperature in the contained cold aisle, which is maintained at 24 degrees C (75.2F).

Most data centers operate in a temperature range between 68 and 72 degrees, and some are as cold as 55 degrees. Raising the baseline temperature inside the data center can save money spent on air conditioning. Data center managers can save an estimated 4 percent in energy costs for every degree of upward change in the set point. At 75 degrees, the Wynyard facility remains within the range recommended by the American Society for Heating, Refrigerating and Air-conditioning Engineers (ASHRAE), which recently expanded its recommendations for ambient data center temperatures, raising its recommended upper limit from 77 degrees to 80.6 degrees.

Half of the Wynyard facility is now complete, comprising four data halls, with room to create four more data halls as demand dictates.
