Is there an accepted protocol for modeling in eQuest VRF systems with DOAS that does not require an exceptional calculation for seeking credit for EAc1? There are a variety of strategies that could all be considered to trigger an exceptional calculation as they are all indirect methods to manipulate eQuest/DOE2.2 to model something outside the normal inputs.

The VRF protocol we have used is from the Oregon Energy Trust. There are some that would likely be acceptable from manufacturers including Daiken and LG. A simple web search will find these.
Modeling VRF in eQUEST requires a work around as the software does not directly model this system. Any work around requires an exceptional calculation.
Exceptional calculations are required for, 1) claiming process energy savings, 2) when doing a work around, and 3) when violating a modeling protocol to show savings (like changing a schedule).
