Hello, I have two specific questions, please help me working them out.
1. At the begining, there is a red exclamation mark that says this: ''the space occupant densities used to determine occupancy for this credit should be consistent with WEp1, WEc2, WEc3, and SSc4''. However I normally take these values from ASHRAE 62.1-2007 table 6.1, whose Occupant Density is different from the FTE calculations for the mentioned credits. So, I think that I only should follow ASHRAE because it gives me more stringent results (i mean more levels of ventilation). Is it correct?
2. The ventilation design includes 3 big supply fans that take outdoor airflow to all the future tenant spaces (offices), the issue is that most offices have three intakes for these fans, however when I try to fill out the form for this credit, each office is supposed to be supplied by only one fan. So, is it possible that I get an ''equivalent fan'' by summing the CFM per fan for all offices?
Thanks in advance.

Actually, I've read on page 410 of the Reference Guide that these occupant densities should be taken from the standard ASHRAE 62.1-2007 (table 6.1); besides in the IEQ p1 form, there is no a link between those occupancy values and the credits mentioned in the red exclamation mark (WEp1, WEc2, WEc3 and SSc4)
