This Climatic Power Calculator calculates the total power usage and power costs for Data Centers. The square footage of the computer room assumes that it consists of all equipment except any related to cooling. The cooling power and its cost are calculated by adjusting the cooling efficiency rate for both Climate and Cooling Equipment. The entry cells are highlighted in yellow. If you set the requirements for both Location A and Location B, you will be able to see the difference in costs between the locations. Note: The Cooling Type of "Central Chilled Water System" includes a Water-side Economizer.
