Using Outside Air to Keep Data Cool

Caterpillar's main data center has improved greenhouse gas emissions by about 2,500 metric tons of CO2e annually, the equivalent of removing nearly 500 cars from roads. This has been achieved by efficiency improvements to the building's air conditioning system, which runs continuously. Improvements include an automation system that uses more efficient motors for the existing air handlers and equipment that takes advantage of outside air to cool the office during cooler months. In addition, a waterside economizer uses a heat exchanger and outside air in cold months to make chilled water to cool the inside air. Finally, an efficient chilled water plant creates the cold water necessary to keep the data center and office spaces at suitable temperatures in warmer months.
