I have a question about the 'Surface Heat Storage' output for a drop ceiling surface. The surface energy does not cycle with its temperature as I would expect. Instead, it appears to accumulate "infinite" energy over time.

The linked files are for a Medium Office prototype building I chose to illustrate the issue. I included the heat stored by the Roof, which does cycle with temperature as expected.

IDF and Output file: Any insight is very much appreciated.

Thank you,

I've been troubleshooting this a bit and as far as I can tell, the issue appears to affect Interior Surfaces and not Exterior Surfaces.
