Hello, I was doing the HVAC system and I am a bit stuck. The model I'm doing has a gas based radiant heating system where there are pipes under the floors which has heated water running through them. The water is heated by a gas boiler probably (we're not sure if we want to use gas or electricity). Is there any way I can model this in Open studios ? I tried to do it but I got totally confused.

Kind Regards, Rafid Khan

Create a hot water plant that looks something like this. You will need to grab a pump, boiler, and setpoint manager from the library.

Selecting from the library, drop zone equipment on the zone.

Click on the name "Low Temp Radiant Var Flow" and connect the zone equipment to the hot water plant using the "link" icon in the inspector on the right.

Create a construction internal source and assign it to the surfaces that you want to be radiant surfaces. Notice in the third screenshot that ZoneHVACLowTemperatureRadiantVariableFlow has a property "Surface Type" that needs to match the surfaces that are assigned the internal source construction. In this example Surface Type is set to floors, so you need to assign the internal source construction to the floor surfaces of that zone.

@Kyle Benne - I think the model also needs the Construction:InternalSource object for the radiant system to work, correct?

Good point. I'll add another step.
