EnergyPlus sizes coils to meet zone sensible loads. You might try increasing the Sizing:Zone Zone Cooling Design Supply

EnergyPlus sizes coils to meet zone sensible loads. You might try increasing the Sizing:Zone Zone Cooling Design Supply

I think that's a fair statement. You should be OK to simulate cooling and heating set points closer than you would expec

In EnergyPlus, the VAV box will try to meet the zone load, cooling or heating required to meet the thermostat set point

@kwalkerman you might try checking the thermostat control type in winter and make sure it's dual instead of heating only

This would appear to mean that the document is already open/locked by another process. You could try deleting that file

Did you check that the floor has no heat transfer? That would be the first thing I checked.

The plant water temperature is not hot enough to heat the air passing through this coil up to Controller temperature set

I added a ZoneControl:Thermostat object to each zone and the simulation now runs.

Try removing the Controlling Zone or Thermostat Location name and leave that field blank. I would still like to see the

Also, what version of E+ are you using?

@zeroJ this should work with setpoint control. send me the idf file, see my profile for my email address

Look at SetpointManager:SingleZone:OneStageCooling and SetpointManager:SingleZone:OneStageHeating to see if that gives t

The air flow rate is showing an average across the time step. It's: mass flow rate = design mass flow rate * part load

The building data does look close and the chiller data matches at peak, so that's a good sign. It looks like there are m

You can plot the heat index for each zone. The description for how to do this is here: https://openstudiocoalition.org/g

Look for something that schedules a plant on and off, in the Plant Equipment Operation Scheme: PlantLoop, Chilled Wat

You could look at the plant outlet water temperature and the chiller evaporator heat transfer to see if the chiller is r

The cooling coil outlet air set point temperature is 17.65 C and the coil entering water temperature is 19.46 C so it is

@mikiksoar9@gmail.com could you please provide the input file that shows this warning. And which multiplier you are refe

You should be able to create that table using Output:Table:Monthly and Output:Table:Annual. Not sure if you can do that

So according to the above plots the HeatAndCool terminal unit is not responding as originally intended. Given the 2 inde

I did review the code for each of these terminal units but it is difficult to say if there is an actual difference. The

@Yagnik the cooling load increased because the space temperature decreased due to dehumidification. I suggest you turn o

@Yagnik is it a cooling demand increase or a dehumidification demand increase? My first guess is the lower heating set p

I posted issue 10507 to get this fixed.
