This study consisted of an investigation into several aspects of providing ventilation in counterforce risk- and host-area shelter facilities. Ventilation concepts, including the characteristics of methods for providing ventilation and the shelter characteristics affecting ventilation, were reviewed. Ventilation kit requirements were developed as a function of shelter ventilating characteristics. In defining ventilation kit requirements, optimal ventilation kit deployment so as to minimize the number of devices required per shelter story was assumed. Data derived from the NSS-CRP Master File and from a sample of NSS shelter facilities were employed to define the ventilating characteristics of the shelter facilities in each counterforce risk and host county. These data then were used along with pertinent counterforce risk- and host-area characteristics shelter requirements and zonal ventilation requirements to estimate the ventilation kit requirements by county, counterforce area, and FEMA Region. Estimates were computed under both best case and worst case assumptions. Under the best case assumption, wind driven ventilation could deliver 8,692 cfm to any aboveground story. No shelter story could be adequately ventilated by wind-driven ventilation under the worst case assumption. In computing the ventilation kit requirements, the numbers of shelter stories requiring no ventilation devices, only Kearny pumps, only PVKs, and combinations of Kearny pumps and PVKs were compiled.
