Hello , I am a student who has recently used open studio, I am creating a small project concerning several apartments powered by a radiant floor heating system. The difficulty that I have encountered is that of not being able to define the system as I would like, as I do not know where to find the '' Coil Heating Low Temperature Radiant Constant Flow '' and an air-water heat pump for powering the system from insert both into the HVAC system. I tried searching in the BCL library but I find only an example of a system already defined called AEDGOfficeHvacRadiantDoas. I would be grateful if someone could give me help thanks.

Low Temp Radiant Constant Flow is a zone hvac object, so you will find it in the model library in the Thermal Zones tab in OpenStudio.

Note that the default controls for radiant systems in OpenStudio use the zone air temperature to ramp the radiant heat system up or down and can lead to severe oscillatory behavior. Depending on your project, you may want to emulate the radiant heating system with another object, add your own custom control scheme with EMS objects, or wait until the next OpenStudio release to take advantage of the radiant system BCL measures available in that release.

OpenStudio does not have a central air-to-water heatpump object in the GUI yet. It is in progress in EnergyPlus and will be added to OpenStudio once available in EnergyPlus. For now, you can use DistrictHeating and DistrictCooling objects on the plant loop and then post-process your efficiency values.

Thank you so much for the quick response and for the details of the low temperature radiant floor. Now I found what I needed. Now I should try to visualize the internal temperatures of the thermal zones exiting the simulation, possibly in degrees celsius with graphs. But I think this question has already been asked. Thanks again
