Hello,

I got a simple question and read most comments here and in NC, but it seems I cannot find a similar question.
In my understanding, the regularly occupied areas in IEQ 8.1 and 8.2 must be consistent to each other, and that should be net floor areas.
Also, to fill out the supplemental spreadsheet, you'll need to know the floor area, not only the ratio of daylight area between 10-500fc.

Now, if you use simulation method for 8.1, do you model a building with thick walls to get the result in net area? i.e. modelling the rooms and extra wall spaces? Or is it OK to model the building with single lines and run simulation (wall thickness = 0: gross area), then estimate the result in net area in any ways like; 1) multiplying the each area's result daylit ratio to its net area or 2) counting the calculation points within the net area space (excluding the points within walls/furniture/shelves) and re-calculate the daylit area? Is there any established method for that?

Alternatively, is calculating the gross areas for both credits in this case all right? - that may affect the result in negative way though.

I haven't submitted any project using IEQ8.1 simulation method yet and I appreciate to hear any thought about that.

Thank you.
