How do I subtract parking when I am submetering? Follow

Excluding parking is the most accurate way to benchmark a building.

If your parking energy is included in your property's master meter, you'll need to subtract this parking energy usage from your property's total energy use. You can either:

  • Do the math outside of Portfolio Manager (total energy - parking energy = building energy)
  • Enter a 2nd meter for parking and add negative entries. This way is our preferred method, especially for certification because we like to see the math.

Also, make sure you:

  • do not include your Parking GFA in your Property GFA.
  • do not create a Property Use for parking -OR- if you start submetering after you've been benchmarking for a while, then "update" the Parking Property Use's Gross Floor Area (GFA) to zero on the date you start submetering)
