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

Does anybody have an idea as to why ?
