Has anyone submitted a residential project that has pursued the intent of the MERV 13 filters in an alternate compliance path? As far as I'm aware, there are no LEED Interpretations that deal with the difficulty residences have in meeting the MERV requirements.

Green Builder, first question is whether you should be doing LEED for Homes since it's residential. But assuming you made the right call there, the MERV 13 requirement has always been a bugaboo for multifamily and hotels, as we note in our guidance above under the Bird's Eye View. I am not aware that this has been resolved.

I agree Tristan- I have never seen anyone successfully implement an alternative compliance path to using MERV 13 filters, except potentially in the case of electrostatic filters which seem to be potentially acceptable, but I have not seen a fast and hard example of those being accepted yet either. Reviewers have, in the past, simply said that this credit is unavailable if you can't meet the MERV 13 requirement.

I'm facing the same difficulties for LEED Homes which the duplex is using VRV system. We can't find any VRV product can install MERV 13 and provide sufficent static pressure... Any suggestion is welcome.

Medium or High Static Ducted Fan Coil units (Mitsubishi, Daikin, LG, etc) have 0.6-1.0" of static on some of the larger models. To allow for the MERV 13 you could potentially build an oversized plenum box behind the unit that is big enough to reduce the FPM across the filter. Then you may have enough static. You don't have to get every credit. That's why LEED give you many credits to choose from.
