I found the video about meeting the ventilation prerequisite very useful. I still have some questions that I hope can help other project teams:

1.Can we perform the VRP calculation including only the critical zone (meeting rooms) and disregarding other non-critical spaces?

2.If a system does not comply with ASHRAE 62.1-2010 because small VAV-boxes were installed and they do not provide the OA rates required by the calculator, does the project fall under the Case 2? Can the project comply with the prerequisite just measuring the outdoor air provided by the UMA and providing 10 cfm/person?

3.Is tenant ductwork a required documentation for certification? Many times, the false ceilings is inaccesible and the plans cannot be drawn up.

4.Natural ventilation is no longer accepted as the only means of ventilation. Does it also apply to bathrooms? Does a naturally ventilated bathroom need an exhaust fan?

Thank you!
