Using outdoor wind factor method for indoors

Hi everyone,
We’ve been working on generating a method for indoor CFD studies that is mesh refinement independent and to do so, we’ve run a test case for 8 different wind directions, independently, for varying wind speeds and mesh refinement levels. In the end the results generated seem to be producing a sort of linear trend. (attaching the excel sheet to this post)

I wanted to know if the wind factor method used for outdoor simulations can be used for an indoor run as well?
