I am trying to run the combined example project (combining residential and commercial workflows) with a non US epw weather file and for some reason the project doesn't run. I made sure to change the weather file names in the features .json file and in the base_workflow.osw from the mappers folder but still didn't work. I tried to run the same feature file and scenario with the default weather file (from Buffalo) and it worked so it seems like the residential feature is not finding the weather file in the weather folder? When I run the project, it creates the folders for each feature in the Run folder, but the residential feature folder is empty and the other features only have the in.osw files on them.

Any idea how can I fix this issue? Thanks in advance for your help.

This worked! Thank you so much @kflemin

I am not sure if what I am trying to do is feasible and logic. I want to control a constant flow low temp radiant system based on the radiant surface temperature (in my case ceiling surface temperature). I tried to add a EMS sensor for Surface Inside Face Temperature for the Ceiling surface; for the actuator I am using "Constant Flow Low Temp Radiant” with the control type “Water Mass Flow Rate”. My problem is that I am not sure what should be the logic of my program. Basically, I want to provide chilled water only after the heat gains from a room have melted all the phase change material (PCM) in which the pipes of a radiant system are embedded. I am assuming that all the PCM is melted when the temperature of the ceiling is a couple of degrees above the melting point (around 23C). In my case, I want to run the chilled water when the surface temperature (which in the model should be the same as the PCM temperature) is above 25 C, which should be an indication that all the PCM is melted and needs to be regenerated. The chilled water is used to regenerate (solidify) the PCM by reducing its temperature to 21 C. When the temperature reaches 21 C, the chilled water stops and allows the system to work passively by absorbing internal heat gains until the surface temperature (PCM temperature) reaches 25C, when the system starts to work again.

Any suggestions???
