I want to use OpenStudio for a single house. I had create a model with different spaces and thermalzones. Now I want to create the Heating in this house. It should be an european heating system. This means without airflow, cooling and with a convective system. Normally there is a boiler, which heats the water, which flows to the different rooms and heat the room air by a convective body. It is possible to create this system in OpenStudio? If so, how can I create this?

Yes, that's called a hot water baseboard.

In OpenStudio you assign these by going to the "Thermal Zone" tab, and in the bottom of your library you'll find "Baseboard Radiant Convective Water" and "Baseboard Convective Water".

Behind the scenes, here are the E+ objects and their documentation to know the difference between the two and how to use them:

yes, that is what i am looking for. But when I have the baseboard in the thermalzone, i get an error in energyplus. i have to create a hvac system. how would it look like with the thermalzone and baseboards?

If you have a water baseboard, then you need something that can supply hot water to it, that is a plant Loop with a generation system on it (typically a boiler, or a District heating object), and then you'd connect the baseboard to that plant loop.

Alternatively if you are only playing around for now you can also choose an electric baseboard.

thank you for your answer. Yes i have entered some water baseboards, now i have the empty plant loop and enter a boiler. But when i add some thermalzones the plant loop get some empty branches. How should i connenct the baseboard to the plant loop?!

This is not an answer, either post as a comment or update your initial question...

Either on the Plant Loop, right panel under "My Model" search the baseboards. Or on the "Thermal Zone" tab, you click on one of the baseboard, then in the right panel you find the "link" tab (looks like a chain link), and you put a checkmark on the right plant loop (you should only have one here anyways).

I´m sorry. I wanted to add some pictures. This is not possible in the comments. Therefore i entered an answer. Thanks, yeah the problem was that in the right panel int the hvac tab there was no baseboards. But the other way add the baseboards to the plant loop. Thank you! i will try to run it.

It doesn´t run. it failed by 75%. The error is in eneryplus:

Severe * IP: IDF line~100699 Error detected in Object=PLANTEQUIPMENTOPERATIONSCHEMES, name=PlantLOOP OPERATION SCHEMES * ~~~ ** Field [Control Scheme 1 Schedule Name] is required but was blank

Now I try to fix it, but first i have to read what the scheme is. or can you tell me and where i can fix it?

THis is turning into a one on one tutorial.

You need to add a setpointManager:Scheduled on the Supply outlet of your plant loop

Hi also the problem was fixed by version with os 1.10. But now I have the problem that in my simulation results are no heating load or energy use because of heating exist. Do you know why?

I have for each ThermalZone one Baseboard, which are in a plant loop, with a Hot Water Boiler, Setpoint Manager Scheduled and a pump. The Schedule is a Hotwater Schedule with Temperature till 85 °C. The simulation process is successful, but there is no results...
