I was under the impression that every LEED project would need to demonstrate use of MERV 8 filtration during construction due to the fact that building commissioning is a prerequisite of LEED and startup, TAB and commissioning constitutes use of the HVAC equipment during construction. Is this assumption incorrect?

Hi,
I am also under this impression - can anyone confirm Marcia's assumption above?

As a matter of practicality, you are probably right that startup, TAB, and commissioning will normally occur during construction, so it would not be a bad idea to require documentation of MERV 8 filters during construction for all projects. However, based on the flush out reference guide language for Credit 3.2 and on past experience, I believe that if balancing and commissioning are done after completion of all punch list items, after installation of all finishes, and after final cleaning, then the operation of the HVAC equipment would not be defined as "during construction".
