Yes, to receive ENERGY STAR certification, you need to enter 12 months of actual, measured, whole-property energy use data for all fuels used at the property. For multifamily properties, this requires complete energy data for both the common areas and all resident units. For office buildings and warehouses, this includes all common areas and all tenant spaces.
We recognize that most properties don’t have aggregated whole building data for their resident or tenant spaces. Therefore, we recommend that you estimate this data so that you can still benchmark; you just won't be eligible for certification.
More and more utilities are starting to offer aggregated whole building utility data. See this map of utilities who are providing Whole Building Data.
