Zone Ideal Loads mismatch
Hi guys
I can't get the following equation (for both heating and cooling) to match in my simulations (example file idf):
Zone Ideal Loads Supply Air Total Cooling Energy + Zone Ideal Loads Heat Recovery Total Cooling Energy
= Zone Ideal Loads Zone Total Cooling Energy+ Zone Ideal Loads Outdoor Air Total Cooling Energy
<=>
2312.1212797468634 + 0 = 8598.715438236986 + 77.11803171210939 [kWh/year]
EnergyPlus version 8.5
----- Update ----
Have the same issue in version 8.9, also for both heating and cooling

To help others answer this question better, you should paste in the objects that appear in your expanded IDF (file ending in [name of your IDF].expidf). Since you are using the HVACTemplate:Zone:IdealLoadsAirSystem object, this will be expanded into one or multiple "standard" objects before running EnergyPlus.
Also, be careful about using the correct documentation. Your model is for v8.5, but the documentation "Source" link you provide is for v8.7. Here is the same outputs section for v8.5.
Thank you @Aaron Boranian ! I have updated the post with your suggestions
