[Bldg-sim] [Equest-users] Problems of energy simulation(HVAC part) in winter

Just a quick guess.  Have you confirmed the outdoor air entering the 
building (infiltration plus ventilation air) during those winter 
months?  Also confirm HVAC systems run hours.  A balancing report is 
a good place to start.  Logging fan and pump hours helps especially 
if the BAC is already keeping those logs.
