Data Center - Climatic Power Calculator

This Climatic Power Calculator estimates the total power usage and power costs for Data Centers. The square footage of the computer room includes all computer equipment and CRAC (Cooling Room A/C) units. 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 two locations.
