Hello. I'm working on a C&S project and have a question regarding the documentation of the IEQp1 credit. During the design a single tenant was found to occupy the entire site (700k sf). We worked hand in hand to establish the AHU/RTU outside air quantities. I do not have a plan indicating the tenant's layouts. I also am not documenting the distribution ductwork on the floors. My question is how exactly to document the ventilation. I am thinking that I can do the 62.1 calcs, using a generic set of rooms (conference rooms, offices, lobbies) and drafting a narrative to explain my assumptions. Is there an issue if I use the ventilation calcs that the fit out engineer has developed for their layouts instead?

Randy, if you haven't already checked out CS Appendix 4 in the LEED Reference Guide, I think that offers one piece of the puzzle here.

I have the same question as Randy I think.
If we do not account for the fit-out, and take the office space as a single zone, the fresh air requirements will be different than if we consider some meeting rooms etc. (with a probable fit out); I think that by taking in consideration that one AHU is supplying air to several rooms, meeting rooms can become critical spaces that will influence the minimum fresh air.
I don't think this case is addressed in the reference guide, where the fresh air and AHU is taken care of in the C&S scope, but the ducting and terminal units design is still unknown.

I just received a comment on a review saying that it is not acceptable to account for the entire office floor as "office space". Conference space areas must be approximated and included.
I cannot find a LEED acceptable default value to use for % of office space that should be considered conference rooms. Does anyone have one? (This guidance is not included in the LEED Reference Guide Appendix 4).

We have a similar issue in that our CS project is providing open office space and therefore 1 zone - we have provided a notional layout for the daylight and views and thermal control credits however these are only theoretical given that it is a Core and Shell building - are the reviewers expecting the ventilation rate calculations to be based on our theoretical notional layout or are there acceptable default %s that can be used for certain building types?
