Modelling a Low Temperature Radiant Floor

Hello everyone,

I have been encountering a problem lately when I try to model a radiant floor in OpenStudio.

I am currently using the OpenStudio 1.10.0 plugin for SketchUp.

My building is a residential building with 6 stories plus 2 parking lots underground. After setting all thermal zones and space types, I use a HVAC system template found in BCL(by apply measure). The HVAC template I used named AEDG Office HVAC radiant DOAS.

When I run the simulation, sometimes it shows errors, sometime it doesn't. It seems very random. Does anyone know how to fix it? Errors:

Process exited with a non-zero exit code of: 1 Error report file indicates that the process did not complete successfully GetSurfaceData: There are 24 degenerate surfaces; Degenerate surfaces are those with number of sides Weather Simulation requested, but no weather file attached. GetNextEnvironment: Errors found in getting a new environment Error condition occurred. Previous Severe Errors cause termination.

Thanks for any help.
