I am studying the results using an idf file with ideal loads instead of HVAC detailed, and I am finding unexpected results. I am considering the original location (Buffalo, NY, USA), whose weather is winter-dominated. However, the ideal load for cooling (257.92 GJ) is 2.3 times larger than that for heating (111.28 GJ). On the other hand, for the original idf (that with HVAC), the energy for heating (225.11 GJ) is much larger than that for coolig (70.95 GJ), which seems to be far more reasonable than the results for ideal loads.
