I am working on a model which has Desiccant wheel in design case. Do we need to model desiccant wheel in baseline case as well? I dont see any section related to this in ASHRAE 90.1, however, in 90.1-2010 Performance Rating method reference Manual under section 3.6.7.2, the baseline building says Not applicable. Can anyone please clarify on this?

Thanks in advance,

John
