Short Answer: Using "Estimated" Data Center Energy allows you to get a score and certification when the required IT Energy meters are not available:
- Data Center Energy Estimates are calculated based on your Data Center's Gross Floor Area (GFA), however the estimate will only apply to up to 10% of your total GFA. For example, if your Data Center is 15% of your property's GFA, you will get credit as if it were 10% of your GFA. If your Data Center is more than 25% of the total property GFA, you cannot use Estimates.
- This estimate is available to all Data Centers located within another property. Stand-alone data centers cannot use Data Center Energy Estimates.
- There is a Use Detail for Data Centers called “Apply Data Center Energy Estimates”. If you select Yes, you'll be asked to input the “Current as of” date (the date that you want to start applying the estimates). Most people should enter the earliest “Current as of” date (the date your property was built). This will be the most accurate way to compare your building’s progress over time.
In the weeds: Data Center Energy Estimates work similar to parking, where we estimate the amount of energy a typical Data Center would use per square foot, and subtracting this amount from your actual energy use to get an estimated energy use for your property without the Data Center. This enables the property to be evaluated as though it does not have a Data Center. This is also the reason Data Centers more than 25% of the property GFA cannot use Energy Estimates because it doesn't meet our eligibility criteria.
Separately metering your IT energy is still the best practice for monitoring your energy use and will provide the most accurate metrics, but we understand that is not always feasible.
