To whoever can help me!
I am bidding on a two-story building. The first floor is 33,000 ft.² and the second floor is a little over 18,000 ft.²
Each floor is supplied by outdoor fresh air from two independent units. In addition there is a secure location that has its own outdoor air unit.
Within this building there are multiple fancoil units split system units and chiller systems.
What I am hoping to get answered is the following:
According to lead credit 3.2 option two, I would need to collect five indoor samples to achieve this credit successfully. Two on the upper floor, two on the lower floor, and one in the secured location.
I am just wanting to make sure that I do not need to collect any additional samples for anything I may be missing that relates to obtaining this credit for my customer(other than the outdoor control sample of course).
Anybody who could help answer this question for me as soon as possible would be greatly appreciated as my customers is hoping to get a bid from me by tomorrow.
Thank you very much in advance.

You are correct unless one of the 1st floor spaces is over 25,000 SF then you would need an additional test. Don't forget the outside baseline sample. It is always a good idea to spot check other main areas of high usage and low ventilation for reference but not necessarily required. Also if carpet is not CRI certified than you will need added testing for 4-Phenylcyclohexene (4-PCH). Are you performing and getting the actual results on site or are you using sample kits from a distributor? You should check out the LEED ver. 3 2009 Guide for further info.
