Analysis of the ventilation requirements in parking garages.

In this paper, analysis of the ventilation requirements of enclosed vehicular parking facilities is discussed. First, a compilation of existing U.S. and international standards and codes pertinent to the ventilation of enclosed parking facilities is presented. Then, the results of a field testing study are summarised to determine the actual ventilation rates and the contaminant levels in seven U. S. enclosed parking garages. Finally, this paper presents a new design method that provides the minimum ventilation rate requirements for enclosed parking facilities.
