m) For variable air volume systems, use electric- or pneumatic-
powered versus system-powered variable air volume terminal boxes. Select
terminal boxes so design CFM is within 75 percent maximum CFM in capacity
range. Provide minimum CFM limit stop for minimum air recirculation in
accordance with American Society of Heating, Refrigerating, and Air
Conditioning Engineers (ASHRAE) standards.
n) Do not use outside air to ventilate plenum spaces above
suspended ceilings in air conditioned buildings.
