Yes. You've identified the correct variables. Your "surface resistance" is the inverse of the surface convection coefficient. (just like R-values and U-Values) Make sure to report at timestep frequency as the default setting is usually hourly.Â
In the documentation you will find that indeed there are a few algorithms that the user can select for the heat transfer methods. CondFD and... I FORGET the transfer function method terminology... are the two main methods.
The algorithms that solve the convection coefficients are also user definable. The default is the "adaptive" one that will include slope of the surface and even air change rates.Â

Hello Jean,
thanks for your reply.To find the actual values used in each calculation step during run time, checkout the list of variables you can report by producing and then looking at the rdd file.So far I have been doing so, but i cannot find reference neither in Eng. Reference pdf nor refer Eplus I/O of which surface resistance coefficient are applied in the reports, just the ones that vary overtime per each surface.Do you know where i can find this information?Furthermore, my problem is, to be aware how what is going on the walls. in terms of heat conduction if iÂ(Surface Avg Face Conduction Rate - Surface Outdoor/Indoor Convection Rate - net Heat storage rate )/(outdoor - indoor surface temp) I should obtain the uvalue, i have estimated.Am I correct?
