Gross Floor Area of Building Space for performance year and baseline year does not include Outlying Properties. Outlying properties in the performance year consisted of less than 4% of the Gross Floor Area of Building Space.

Gross Floor Area is different from IC-2 because of the different performance years (2015-2016 vs IC-2 2017-2018).
