Below wind speeds of 3 mph, the total ventilation rate remained relatively constant to 6 to 8 cfm/man. For the ambient conditions that prevailed throughout the testing period, natural ventilation alone was adequate to limit the effective temperature to 85 deg. F. ET without utilizing all possible inlet-outlet openings available.

The punkah proved to be an effective air moving device when it was placed so that it complemented the effect of any thermal force that was present. The Package Ventilation Kit also proved to be an effective means for moving air through a shelter that had no windows and utilized existing doorways as ventilation openings. During the natural ventilation test the effective temperature of the ambient air and shelter air never went above 85DGF ET. Usually the average shelter ET was about 5DGF above the average ambient ET for the same period. The ventilation rate ranged from 10 cfm/person to 26.5 cfm/person indicating that natural ventilation may be adequate for most aboveground fallout shelters with windows.

The results indicate that a ventilation rate of 3 cfm/occupant is more than adequate to maintain long-term, thermally habitable, shelter environment for 330 occupants for the encountered winter and/or spring conditions. With zero ventilation, the shelter can accommodate from 48 to 90 people. The air leakage varied from 0.043 to 0.055 cfm/square foot of exposed shelter surface. For winter and/or spring conditions, the heat transfer through the shelter surfaces is important in lowering the shelter effective temperature.

An eight-day simulation occupancy test was performed on a second floor 255-occupant fallout shelter, using only natural forces to supply ventilation air. The purpose of the test was to collect data necessary to develop a procedure to predict the natural ventilation rates that will result in above-ground fallout shelters. Moderate prevailing winds provided the primary air moving force; thermal effects were secondary. Even during periods of calm winds, considerable air flow was measured through the shelter (a minimum of 16 cfm per occupant). This test provided further validity to the supposition that natural ventilation is adequate for most above-ground shelters with windows. In general, correlation was not obtained between measured ventilation rates and those computed from methods presented in the literature. Future natural ventilation tests will use more accurate instrumentation.

A series of ventilation tests were performed on an above-ground identified fallout shelter in Wilmington, North Carolina, from 26 September to 30 October, 1963. Ventilation of the shelter at different rates and inlet conditions, corresponding to three distinctly different climatic conditions, resulted in data that were used to develop a method for predicting ventilation requirements for this shelter under any ambient conditions. A daily average 85DGF effective temperature was used as the shelter design point. Minimum ventilation capacities recommended from the test results are: -in a hot humid climate, 21.2 cfm per occupant -in a hot dry climate, 14.6 cfm per occupant -in a moderate climate, 7.8 cfm per occupant.

Ventilation tests of a 240-man above-grade fallout shelter were performed using simulated occupants. Conditioned air and/or outside air were supplied to the corridor-type shelter at rates varying from 3 to 15 cfm. A natural ventilation test was made with one window opened at each end of the 190-foot long shelter. With winds ranging from 4 to 15 mph, the ventilation rate varied from 8 to 11 cfm per person simulated. Much larger ventilation rates could be obtained if more windows had been opened. This test series is one of many performed to determine the minimum equipment requirements necessary to maintain a habitable shelter atmosphere.
