Hello, a question concerning IEQc8.1 & IEQc8.2 . Can we use the net floor area instead of gross floor area for the simulation in Matrix_Table IEQ-1 Daylight and views? I would like to use the net floor area instead of gross floor area in the credit form IEQc8.1 and 8.2,but the "Total regularly occupied area" is linked to PIF3,where the gross floor area is relevant . In my opinion daylight is relevant to the net floor area and not relevant to walls. Therefore I would suggest to explain my opinion for the daylight and the difference between PIF3 and IEQc8.1 & IEQc8.2 in Upload L-10. Has anyone had a similar experience with net floor area instead of gross floor area in credit form IEQc8.1 & IEQc8.2? Thank you in advance.

In table PIF3-1 in PIF3 you'll see the column listed Regularly Occupied Area, right beside Gross Area. This column is what is linked to both EQc8.1 and 8.2. So in that table, you will need to put the regularly occupied area for each space usage type. Which is what you use in the calculator. You can provide a narrative to explain the difference, but depending on whom you get for a reviewer you may be asked to make the corrections in the table in PIF3 and won't get away with a narrative explanation.

I usually use net floor area. I am not sure for CS but for NC, you allow your number within 10% from PlF3. If you are more than 10%, you need to add narrative.
