Beginning August 2018, you will have the option to use "Estimated" IT Energy for your Data Center to get a score and certification. These estimates will be calculated by Portfolio Manager based on your Gross Floor Area (GFA). The IT Energy estimates are available as long as your Data Center is not more than 10% of your property's GFA.
There will be a new 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.
Separately metering your IT energy is still the best practice for monitoring your energy use, but we understand that is not always an option for you.
