It’s likely that you have core zones with internal gains and zero envelope losses which will require cooling even in winter.

What type of HVAC system are you using? If you are mixing heating and cooling airflows, you are tempering the air, and thus having both heating and cooling loads.


Sending us the .INP and .PD2 files would be helpful to investigate it for you.

Dear eQUEST users

I have a fundamental question about my anomalous result. I modeling a
residential (high rise) building in normal way and use various weather
data but finally the summery result contains both cooling and heating
consumption during cold season. I change many options in the
definition wizard for example type of building, utilities energy per
area etc. but the result not changed so much.
I ask anyone who know about the reason to send me an E-mail about this issue.
