I am trying to get ventilation loads out of the the ideal air loads and have tried the solutions presented in the forum but I can’t seem to find a decent solution to fix it. I want the cooling loads to include ventilation loads as per the dehumidication temperatures.

Hey @hmurya ,
The cooling load that comes out of the Read Room Energy Result component includes both the zone sensible cooling load as well as the outdoor ventilation air cooling load.
If you want the load for just the ventilation air, you should see this mech_vent_load output from that same component:
hi Chris, yea i understand that it should show up in mech vent load, but my problem is that nothing shows up in the loads at all, no matter what value I apply.
Are you using an ideal air system? And do your rooms actually have a ventilation requirement assigned to them? Both of these are usually needed to get the mech ventilation load.
Hi Chris,
Yes did all of that. I even ran the sample files that come with installation (full building energy model and shoebox energy model) and both of them dont give any values. The component is certainly running, but its giving me a ‘null’ value.
What version of EnergyPlus are you using? You can use the HB Check Versions component to see this. And make sure that you are following the recommendations in the compatibility matrix:
I have both version 9.6.0 and 22.1.0. Is that what is probably causing the glitch?
This is possible if EnergyPlus has changed the output names on us in version 22.1.0. What does the HB Check Versions component tell you about the version of EnergyPlus used by Ladybug Tools? If it says you’re using E+ 22.1.0, then this could be the problem.
