Data for Canadian cities abstracted from Heating 6* Ventilating, October. 1939. The National Joint Committee on Weather Statistics, in cooperation with the U. S. Weather Bureau, is pre paring revised Degree-Day Normals which will be available in 1946. - bData for these cities and possibly other localities are based on readings taken at more than one official Weather Station during the 43-year period of analysis and are subject to local verification, as these figures are being examined for possible revision by the U. S. Weather Bureau. The calculated heat loss or its equivalent square feet of calculated radiator surface may be used as the unit. The use of the unit equivalent direct radiation is of questionable value when referring to heat transfer surfaces used in warm air furnace or central air conditioning systems. Where steam or hot water radiation is already installed, care should be exercised in using the unit equivalent direct radiation basis for estimating since actual installed radiation may differ considerably from the exact radiation requirements. In view of all these considerations it is believed that the unit based on thousands of Btu of hourly calculated heat loss for the design hour is probably the most desirable, although the one most widely used seems to be units of fuel per degree-day per square foot of
