The LEED Guidebook cites the ASHRAE 2007 Handbook as reference material and the sample Building Operating Plan has an entry for "outside air" indicating comliance to ASHRAE 62.1-2007.
My question:
1) Does the Building Operation Plan have to comply with the latest ASHRAE Standard, in this case 62.1-2007 or is compliance w/ earlier versions acceptable?
2) If compliance with earlier versions is acceptable, how early a version will be acceptable to LEED?
I ask since my client's building has been in operation since 1991, although they have done a good job updating their facility.

You might want to check out the criteria for EQp1. Building's with HVAC systems physically capable of meeting 62.1-2007 OA rates must demonstrate they are doing so during the performance period. Assessing compliance against an older version of the standard would not be allowed, though some building's that can't meet ASHRAE 62.1-2007 can use the other compliance path to show at least 10 CFM / person.
