I received a comment on a review that the occupancies used for EQp1 did not meet the peak occupancy listed on PF3. I have always assumed these as separate issues and argued that we used ASHRAE defaults for EQp1 and more realistic occupancy values for PF3. The reply I received said that these had to match. Anyone come across this before? Thanks!

Hi Janika,I believe these occupancies do need to match and that they auto populate in newer versions of LEED-online forms.

Hi Emily,
They don't auto populate. One of the options for this credit is to use the ASHRAE default occupancies (which we've done) calculated per room type. This is different than what we used to calculate occupancy loads for the building (based on schedule of use) and this is not how occupancy is calculated in PF3. Any other thoughts?

What version of the forms are you using? I may be wrong about the auto-populate, but v04 of this form makes it clearer which occupancy to use. You can download newer forms (assuming you're not already using v04) from LEED-Online under Sample Forms Download. The newer form may shed some light. Otherwise, I'm not sure. Anyone else have thoughts?

Hi Emily,
We are using V03. I don't see in either V03 or V04 where the occupancy would auto populate. It says that PF3 links to SSc4.2, SSc4.3, SSc4.4, and WEp1. The EAp1 V04 form still gives the option to use the default occupancy rates. Where do you see that it makes it more clear? Thanks

Janika,I thought you may be using a beta form, since you're not I don't have enough experience with this credit to help, sorry. Someone else on LEEDUser may have more experience and be able to help.
