[EnergyPlus_Support] Re: Zone Loads

["aleagerman22" <agerman@xxxxxxxxxxxxxxx>]

Good question, and unfortunately, they don't. I'm missing something on the loads side, the sum of all the variables that I listed previously does not come out to be a reasonable value (it's very low). I will investigate further and provide an update.

For more my purposes I'm thinking of using the delivered energy to the space since my system is able to meet the load in all instances.
