All - I always thought that they 5-year exception to the performance period rules on pg. 172 of the reference guide could likely be used for either option, commissioning or the ASHRAE Level II. But, word on the street is that it is intentionally limited to the ASHRAE option, and if you are using Option 1: Commissioning, the cx activities have to fall within the normal maximum 2 year performance period.

Just wanted to spread the word, since this was news to me.
