I'm benchmarking two (or more) connected buildings as individual properties. How do I divide the connected parts? Follow

When you benchmark two or more connected buildings as individual properties you need to figure out the best way to benchmark the "connected" parts. For example, if you have two office towers connected by underground parking and a 1st floor lobby, what do you do with the energy and Gross Floor Area (GFA) from the parking and lobby? There isn't always a clear answer. Here are some things to consider: 

  • Look into what you can exclude (see this FAQ for details.) For example, if you are sub-metering parking, then it should be excluded from your property. See this FAQ on how to benchmark parking.
  • If one of the buildings supplies all the energy to the connected areas, then add all the energy and GFA to that building.
  • If all of the buildings collectively supply the energy for the connected areas, then divide the energy and GFA of the connected part among the separate buildings in the way that makes the most sense based on how the two buildings/towers share the common space.
