Ah, thank you so much Aaron and Lantonshen. I appreciate your input here. Reading through the documentation and links, it does help to clarify the issue a little bit for me regarding this 'Surface Average Face Conduction Heat Transfer Energy' output variable.

In particular, reading (and re-reading a few times....) the detailed explanation for the:

• Surface Outside Face Conduction Heat Loss and the
• Surface Inside Face Conduction Heat Loss

was helpful, and does clarify a bit the results shown in that 'Average Face Conduction' output.

thank you, -Ed
