I have received review comments from a LEED Review Team questioning the results of the 62MZ spreadsheet which identified a Storage Room as the "Critical Zone". The reviewer requests that I revise 62MZ spreadsheet indicating the "correct" critical zone. I have reviewed the imput cells in the spreadsheet and find no mistakes in the input values. The Storage Room which turned out to be the "critical zones" are large storage rooms within a relatively small air handling system. The outdoor air for Storage Rooms from Table 6-1 requires OA ONLY based on Area Outdoor Air Rate(0.12cfm/sq.ft.). No OA is required for occupants since space is normally unoccupied. Anyone else run across this or similar circumstance?? How do I effectively respond to reviewer given these circumstances?? I think providing a response that essentially tells the reviewer to read and understand ASHRAE 62.1-2007 and how results are determined when using 62MZcalc spreadsheet may not be well received.
