All,

I get the following BDL error in my model

WALL has no heat capacity. U-Value used.

I am modeling the baseline envelope as prescribed in Appendix G of
90.1-2004. Referring to Appendix A of 90.1-2004 to model the baseline
envelope, I created layers for the wall construction seen in the attached
screenshot. The resulting U-value for the wall is 0.124. Can I not model a
wall in this manner? It seems specifying the U-value alone in the
construction layer would do the same thing.
