Weather Bureau Data and various other sources, b Column 2. The station designation AF or CO indicates airport or city office station respectively, c Column 3. The elevations marked c are ground elevations of the station. AD other elevations given are the actual elevations of the thermometer bulb above mean sea level, oorrected to 1948. d <pbe periods of record indicated apply only to the highest temperature ever recorded shown in Column , not necessarily include all of the summer months of the first year indicated. The last year indic&ted includes July or August except those marked d which terminate prior to July of that year. e should be noted that Column 6 applies only to airports, as these data for city stations are not avail* Able at this time. The temperature shown is the maximum hourly outdoor temperature which has been foualled or exceeded 2J per cent of the total hours of June, July, August and September for the 5 year period 1935-1939 inclusive. It is pointed out that in most cases the airport stations are outside of the city, and that the data would apply primarily to rural areas. { columns 7 and 8 record wet and dry-bulb temperatures in use by A.8.H.V.E. Members as reported by Chapter Secretaries for various stations. Where such values were not available, the design temperatures published by A.C.R.M.A. or obtained from various other sources, have been inserted. The average wind velocities indicated in Column 9 were furnished by the U.' S. Weather Bureau, corrected to 1947. In general these velocities are averages for the months of June through September. b The bulletin published by A.S.H.V.E. for the annual weather data of Detroit indicates 73 F as the de sign wet-bulb temperature which has been equalled or exceeded 5 per cent of the hours for period 1935-1939. Blank spaces indicate data not available. Table 4. Ventilation Standards* Application Smoking Cfm per. Person Recommended . Minimum** Deluxe ................................ .......
