BOMA 2010 Clarity Needed

Adrienne MacCharles: KingSett Capital; June 26, 2012

Hello,
I have two questions. Firstly, what is the definition of Load Factor A and how is it calculated? How does it differ from the R/U Ratio?

Secondly, what is included in the Gross Up for BOMA 2010 vs. BOMA 1996?

Thank you

Hi Adrienne,

Load factor A (Method A only) is the product of the R/U Ratio of a particular floor of the building and the R/O ratio of the building. In other words, Load Factor A is the total gross-up that is applied to tenants on a floor by floor basis after accounting for the Floor Service and Amenity Areas and the Building Service and Amenity Areas. It doesn't really differ much from "R/U Ratio" except that R/U Ratio is sometimes used for determining the proportionate share of floor common areas or building common areas in the building, such as in the BOMA 1996 standard which used "Floor R/U Ratio" and "Building R/U Ratio". Load Factor on the other hand is the total gross-up accounting for both. To calculate the Load Factor, I would recommend purchasing the official publications at BOMA.org. It is impossible to describe here how to calculate this.
