Strock and C. H. B. Hotchkiss (The Industrial Press, pp. 132-134).. INDUSTRIAL DEGREE-DAYS When estimating the heating requirements of warehouses, factories, and other buildings where the inside temperature to be maintained! differs greatly from the usual inside temperature range of 68 to 72 F, it is common to use degree-days based on temperatures of 55 to 45 F. These are gen erally referred to as industrial degree-days, and are listed in Table 9 for a number of cities using both 55 F and 45 F as the base.. In general, the degree-days (55 F base) are used when the temperature of the heated space is to be maintained at approximately 60 F. For an inside temperature of about 50 F, the degree-days calculated on a 45 F base should be used. The industrial degree-days are useful for estimating fuel consumption by comparison between localities in which the difference in degree-days is not too great, and where the known fuel consumption of one building may be used to determine unit consumption per degree-day. MAXIMUM DEMANDS AND LOAD FACTORS In one form of district heating rates, a portion of the charge is based upon the maximum demand of the building. The maximum- demand may be measured in several different ways. It may be taken as the instantane ous peak or as the rate of use during any specified interval. One method is to take the average of the three highest hours during the winter. These figures are shown for a number of buildings in Detroit in Table 10.1! These maximum demands were measured by an attachment on the con densation meter, and therefore represent the amounts of condensation passed through the meter in the highest hours, rather than the true rate at which steam is supplied. There might be slight differences in these two quantities due to time lag and to storage of condensate in the system, but wherever this has been investigated it has been found to be negligible. v. .
