I recall that there was an issue with entering both system and zone
level airflow values in eQUEST but a search through the archive did not
retrieve what I was looking for. Perhaps someone can jog my memory. In
a review of a model where both system and zone level airflows were
entered for a VAV system, and where zone level values total up /less
than /the system value entered, we find that deleting the system level
airflow increased the overall fan energy. I find this hard to explain.
