### neers (ASHRAEt as published in Chapter 43 of the 1976 ASHRAE Handbook Systems Guide (discussed below) to cal

### culate the average annual energy con- sumption.

The ASHRAE "Modified Degree Day Proceduro" expresses energy consumption as a function of heating load (expressed in degree days), the difference between the indoor and outdoor design temperatures, a correction factor. and theheatloss ofthebuilding in

### which the heat source is installed. In 

### the proposed regulations, the heat provided bS; the heater is 

### assumed to be 

### equivalentto the heat loss of the building. With this as- sumption. the ASHRAE procedure can be used to calculate energy consumption for a particularheatingunit (as opposed to a particularbuDding) •

A degree day is 

### a measure oftheheatIngload on a heatingunit. A'degree day is 

### defined as the difference between the

mean outdoor temperature over a 24- hour period and 65° F. For example. if 

### tho average of thehighandlow temperatures [or a day were 40° F. theheating load would be 25 (65-40) degree days. For primaryheaters of 

### the type covered by this 

### proposal. the average annual heating load 15 approximately 4,000 degree days.

A correction factor, Cd, is 

### used in the ASHRAE procedure.to make the calculated values of energy consumption

more closely approximatefield measure- ments of energy consumption. The cor- rection factor is 

### a function of the outdoor design temperature. Using a graph of degree days as a function of indooroutdoor design temperature difference and the average value of 4,000 degree days, the average Indoor-outdoor design temperaturedifIerenceforprhnaryheat-
