At this time there is no method for sizing coils based on latent loads. There are plans to add this capability in the near future, however, for now the ultimate sizing methods are based on sensible and ventilation loads.
The code does allow using a sizing method based on total loads, but this method simply calculates the load based on MdotDeltaH instead of the sensible calculation of MdotCp*DeltaT to identify the time of the peak zone load. Note that choosing the time that the peak zone load occurs (based on total load) is not the same as identifying when the maximum latent load occurred nor that the coil is sized based on the maximum latent load using the corresponding coil sensible heat ratio.
