S. Weather Bureau Data and various other sources. b Column 2. The station designation AP or CO indicates airport or city office station, respectively. 6 Column 3. The elevations marked c are ground elevations of the-station. All other elevations given are the actual elevations of the thermometer bulb above mean sea level, corrected to 1948. d The periods o! record indicated apply only to the highest temperature ever recorded shown in Column 8, and do not necessarily include all of the summer months of the first year indicated. The last year indi cated includes July or August, except those marked d which terminate prior to July of that year. It should be noted that Column 6 in the United States section of the table applies only to airports, as these data for city stations are not available at this time. The temperature shown is the maximum hourly outdoor temperature which has been equalled or exceeded 2} percent 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 these data would apply primarily to rural areas. 1 Columns 7 and 8 in the United States section and Columns 9 and 10 in the Canadian section of the table record wet and dry-bulb temperatures in use by A.S.H.A.E. members as reported,by Chapter secretaries for various stations. Where such values were not available, the design temperatures published by API or ob tained from various other sources have been inserted. 8 The average wind velocities in Column 9 in the United States section were furnished by the-TJ. S. Weather Bureau, corrected to 1948. In general these velocities are averages for the months of June through September. b The bulletin published by the A.S.H.AJ3. for the annual weather data of Detroit indicates 73 F as the design wet-bulb temperature which has been equalled or exceeded 5 percent of the hours for period 1935-39. | Blank spaces indicate data not available. . * The data for Canada were compiled by D. W. Boyd and Morley Thomas from the records of the Meteorota&cal Division, National Research Council of Canada. . * The highest temperature ever recorded in the Canadian section of the table is for the 30 year period, iszi-1950. where available. In some cases the stations have been relocated and in a few instances some year, are missing. 1 In the Canadian section of the table, the summer design dry-bulb temperatures for the basis of 1, 2}, a and 10 percent are the Fahrenheit temperature values at or above which these percentages of all the July "uriy outdoor temperatures occur, for the years 1941-1950 inclusive. . Most of the wind speeds are based on the periods ending in 1947 which are somewhat shorter than the penods*for the highest temperatures. The three months June, July and August were used. INSTANTANEOUS HEAT LOAD The total cooling load is frequently divided for convenience into two components, sensible heat and latent heat. While this subdivision is no imperative, past practice has found it convenient. A gain of sensible heal is considered to occur when there is a direct addi-
