relationship between ∆T and q, there are cooling or heating loads that vary nonlinearly. Using the bin method results in a more accurate calculation of the total load, Q. When the weather varies hour-by-hour, the demand put on the heating and cooling equipment varies, plus equipment performance varies at different weather conditions.

constant thermostat setting over a cooling season. Equivalent full load heating (EFLHH) hours are analogous to EFLHC; this paper focuses only on cooling.1 The product of the EFLHC and the system’s actual capacity is the amount of cooling the system delivers in a cooling season, as shown in Equation 1.

C. Degree-Hours Heating and cooling degree-hours are defined as the sum of the differences between hourly average temperatures and the base temperature. The number of cooling degree-hours (CDH) in a day is defined as ∑() = = − + N i CDH b Ti Tb 1 (1) where N is the number of hours in the day, Tb is the base

Heating degree-days are the number of degrees that the daily average temperature falls below 65° F. Cooling degree-days are the number of degrees that the daily average temperature rises above 65° F. The daily average temperature is the mean of the maximum and minimum temperatures in a 24-hour period. For example, a weather station recording ...

A high number of degree days generally results in higher levels of energy use for space heating or cooling. Heating degree days (HDD) are a measure of how cold the temperature was on a given day or during a period of days. For example, a day with a mean temperature of 40°F has 25 HDD. Two such cold days in a row have a total of 50 HDD for the ...

percentage of these 6,489 hours each bin represents. Clearly, the 21 hours above 94 F (i.e. ASHRAE’s “1 percent design” for Atlanta) is less than one-half percent of 6,489 hours. Simplistically, one might infer that a chiller in Atlanta spends only one-half percent of its operating hours at a design condition. At least three fundamental flaws in logic make this untrue:

Degree Days Calculated Accurately for Locations Worldwide. Buildings require more heating in colder weather, and more air-conditioning in hotter weather. Degree Days.net provides the data to quantify this and help monitor, manage, and reduce energy consumption in millions of buildings around the world. It is developed and maintained by BizEE ...
