The annual peak cooling value includes sensible and latent cooling? Hello! I am wondering if the 'Annual and Peak Value

internal gains increase when using Template:Zone:IdealLoadsAirSystem Hello! I run two simulations on the same model: fi

Thank you for your help! I will try to fix the size of the cooling coil then!

Hi! I am using HVACTEMPLATE:ZONE:IDEALLOADSAIRSYSTEM and I want to limit the temperature to 26°C and the humidity to 60%. I set the Dehumidification Control Type to constant sensible heat ratio and the Dehumidification Setpoint to 0.6. However it seems to have no effect on the humidity. Is there any way I can limit the relative humidity to a constant value ?? Thank you in advance!

Works like a charm!! Thank you soo much!! you saved my day :)

Hello! I'm new to Open Studio and I tried to import an .idf file, previously generated in EnergyPlus. In EnergyPlus I can simulate it without any error. When I simulate it in Open Studio it doesnt work. it seems to be unable to finde some schedules. I get the error 'Field [Activity Level Schedule Name] is required but was blank' Although this schedule exists. I use Open Studio Version 2.1.0 and EnergyPlus 8.7 which, according to the release notes, should work together... Are there some settings I have to change before I can import it in Open Studio?

Is it possible to use a humidity setpoint just to calculate the idel loads? I build my model now in OpenStudio and it se
