was accepted by the reviewers. In that case I DID NOT separate out fan power from the cooling EER, since otherwise I would not account for the artificial fan energy in addition to the artificial cooling energy mandated by having to model a cooling system.

<b>Subject:</b> [Equest-users] Modeling Zones with Unit heaters as per ASHRAE 90.1. Appendix G<o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>

<div>
<p class="MsoNormal">ASHRAE 90.1. Appendix G says that, even if a zone is heating only in the actual building, a cooling system identical to that in the baseline system should be modeled in the as-built model with intermittent fan operation to meet the loads.
I have seen projects with zones that have only unit heaters with no cooling air supply. eQuest does not allow for modeling of any cooling system in a zone with a unit heater. What would be your approach to solving this problem?
