Hello again, We now have the 62MZ spreadsheet working (thanks again!), but a few more questions have come up as our ME works through it. Can anyone provide some insight on these? 1.

Where can I find the Option B Calculator that is used to calculate compliance with 10 CFM per person for AHU's unable to meet ASHRAE 62.1-2007?

I am working on a building that has multiple floors that are completely stripped and wide open for new tenants to design the layout to.

Hallo, I am wondering what is the Reference Guide referring to when it says "physical constraints of the existing ventilation system".

I was wondering what would happen if we failed to meet a prerequisite such as IEQp1. Would we need to restart our performance period after correcting whatever it is that needs to be corrected?

If the 62MZ calculator reveals that the critical zone is a zone with cooling only (with a min of 0), is that an appropriate reason to pursue Case 2?

I have downloaded the "USGBC LEED 62MZCalc (May 2011) and I have to complete manually the cells that correspondon to the "Inputs of the system".

For LEED EBOM 2009, IEQp1, are exhaust fan test reports required for every fan or just one per type.

Hi All At risk of looking foolish has anyone succesfully presented an AHU serving a single zone when all those zones are identical?
