4337 (RP-945) -- Evaluation of Design Ventilation Requirements for Enclosed Parking Facilities PDF

This paper proposes a new design approach to determine the ventilation requirements for enclosed parking garages. The design approach accounts for various factors that affect the indoor air quality within a parking facility, including the average CO emission rate, the average travel time, the number of cars, and the acceptable CO level within the parking garage. This paper first describes the results of a parametric analysis based on the design method that was developed. Then the design method is presented to explain how the ventilation flow rate can be determined for any enclosed parking facility. Finally, some suggestions are proposed to save fan energy for ventilating parking garages using demand ventilation control strategies.
