What's the difference between Occupancy and Vacancy? Follow


  • Is the percentage of your property’s Gross Floor Area that is occupied and operational.
  • There is only one value for the entire property (view it on Details tab, in Basic Information box, Edit details)
  • The value does not affect your metrics – metrics are based on the specific use details, like the number of workers.
  • There are minimum occupancy requirements for ENERGY STAR certification for these property types:
    • Office/Bank/Courthouse/Financial Center – 50% occupancy required
    • Hotel - 55% occupancy required
    • Multifamily – 75% occupancy required
  • If you have people working in all floors/areas of your building then you are 100% occupied. You do not need to count empty cubicle spaces – but, you do want to make sure your number of workers is correct when tenant usage patterns change.


  • Vacancy refers to a portion of the building that is not in use. This is not a few empty cubicles but rather a suite or entire floor that is not leased or occupied.      
  • When more than 10% of your property is vacant, you are required to create a separate “Vacant Space” property use for the following property types:
    • Office
    • Medical Office
    • Bank
    • Courthouse
    • Financial Center
  • A Vacant Space should be entered with:
    • The property type that corresponds to what would be there when occupied (Office, Medical Office, etc).
    • Weekly Operating Hours = 0
    • Workers on Main Shift = 0
    • Number of Computers = 0
    • Percent Heated and Percent Cooled = Report conditioning as it occurs in the vacant space
  • For other property types (e.g. K-12, Hospital, Retail, Hotel, etc.) it is less common in the market to have portions of the building that are unused. Therefore, there are no special entry requirements for any other property types at this time.

Occupancy and vacant spaces must be tracked and edited independently – they do not automatically update each other. However, we are evaluating ways to combine this information in the future.
