Figure 8

Tropical buildings distance (in temperature) from 25% _G7 transmission risk contour. In this figure, outdoor conditions (street ambient values) contrast with conditions inside of buildings. 20% or more of the bank branch, office, retail, hotel and dining locations displayed good aerosol transmission conditions (i.e. below the 25%_G7 transmission line) with sample size > 20. Temperature and RH of terminals (for aircraft and buses), hallways in shopping malls, and hospitals, was considered indicative and thus shown, though having smaller sample sizes than desired. Although there were only 8 different hospitals surveyed in tropical nations, hospital data was included because hospitals receive ill patients, and many of these nations have only one major facility. These data suggest that hospitals have a relatively high investment in HVAC in the tropics, on the order of retail and high end hotels, presumably for comfort of patients.

Black and dark gray pie charts are shown for datasets with N greater than 20. Datasets with less than 20 measurements in the sample are shown with light gray and white to emphasize the difference in sample size.
