NC-2009 IEQc3.1: Construction IAQ Management Plan—During Construction
Does a project where all exhaust air is exhausted directly to the outside need MERV 8 filters at each grill to meet EQc3.1?
This is a lab project where supply air is 100% OA. There is no mixing between supply and exhaust.
Has anyone dealt with this in the past? Thanks

Erik- I've had this exact situation before! The good news for you is that since you are not using any return air as part of your supply system, you do not have to use the MERV 8 filters, as the MERV 8 requirement only applies to return air, not outside air. You still want to take steps, though, to make sure that construction dust and debris does not end up in your supply duct work by making sure the system is closed and sealing any branches that are not being used during construction.

In this case, how would you fill out the IEQc3.1 2009 template? Assuming the HVAC/AHU was being operated during construction. The LEED Online form asks you to select an option and this option would require filling information about the filtration media so I am just wondering how you could circumvent that via LEED Online. Maybe select the "special circumstances" option?

Courtney, the 'special circumstances" box sounds like the best option for this, I agree.
