My company uses HAP for building load analysis, and we'd like to be able to use the gbxml export from Revit MEP and import into HAP. I've been working on this for a few weeks, and I always get the same error message in HAP when I try to import:
Transfer function coefficients could not be generated for this assembly of material layers. Generally this problem occurs when the overall thermal resistance or thermal capacitance of the assembly is too small or too large. Therefore, the construction of this assembly must be revised so its overall thermal resistance and capacitance fall within a more normal range of values.
I'm using a linked (very simple) revit architectural model. I don't have any errors in the revit model, and all of the spaces are defined (including plenums, etc.). Has anyone else had a similar issue, and were you able to find a resolution?
Thanks,
Shane
