Hi, I model the baseline in OpenStudio according to ASHRAE 90.1 APP G for a apartment in NYC, the hvac system is PTAC. The heating consumption is too small to compare with cooling consumption (1:2 approx). According to the previous experience, the heating consumption is too low.
OSM file and simulation result are shown below:
Does anyone can help me to figure out what's going on and diagnose the problem in this model?
