We have just received a request for additional clarification during our final review of our LEED-EBOM 2009 submission, asking us to confirm the date of our TAB report, and pointing us to the the Calculations section of the Reference Guide where it notes that 'Outdoor air testing generally must occur during the performance period (maximum of 2 years).' Our TAB report was generated during the design phase, just prior to the performance period so we could confirm our calculations prior to the start of the performance period, but within 2 years of the conclusion of the performance period. Is there any way to avoid the creation of another TAB report (and its associated cost) after the fact? Given that we were confirming our baseline condition in close proximity to the performance period to make sure we would be compliant, this appears to meet the intent of the prerequisite language.
