Isolate Flow Paths to Non-essential or Non-operating Equipment

Keeping the non-essential or non-operating equipment/users connected to the main fan system results in energy dissipation in non-useful work. Therefore, by isolating such equipment from the main fan system energy efficiency and system performance can be increased.
