C.7.5 c. Prevailing winds, adjacent buildings, and discharge velocities must be taken
into account so that discharge is not entrained within an outdoor air intake.
C.7.5 d. Exhaust outlets shall be located away from occupied areas or from doors
and windows. The preferred location for exhaust discharge is above roof level. Care
must be taken in locating highly contaminated exhausts and discharges from engines,
fume hoods, BSC’s, kitchen hoods, and paint booths.
C.7.5 c. If fume hood exhaust systems interconnect with other exhaust duct systems,
appropriate engineering equipment, principles, and controls are necessary so that
cross-contamination of the general ventilation does not occur.
C.14.4 Hazardous Waste Storage and Handling
h. A separate ventilation system shall be installed for the storage room. Exhaust shall
be directed away from the building and the buildings’ air intakes.
ASHRAE, 2011 HVAC Applications Handbook, 2011, Pg. 16.13 STACK HEIGHTS
AND AIR INTAKES
For complex buildings or building with unique terrain or other obtacles to the airflow
around the building, either scale model wind tunnel testing or computational fluid
dynamics should be considered. HVAC design engineers that do not have the
analytical skills required to undertake a dispersion analysis should consider retaining
a specialized consultant.
This section of the ASHRAE Handbook
provides extensive guidance and other
references for determining required exhaust
stack height to avoid exhaust re-entrainment.
