Hello,

I am working on a Trace model that will eventually be a LEED submission.  My baseline system is PTAC (considered a residential building).  I believe I set up the system correctly in Trace, however the energy usage was not as much as I would have expected, compared to my proposed case(s).

Digging a little deeper, the PRM summary report breaks out the energy use for different catagories, and the "Heat Rejection" catagory is much much less on the baseline case.  This strikes me as quite odd, considering the heat rejection equipment is nothing more then an air cooled condenser.  I used the 90.1 minimum air cooled condenser in Trace.

I was wondering if there were any words of wisdom from the Energy Models braintrust on this.  I have hosted my model below.  Do I have the PTAC baseline set up correctly?
