The azimuth is expressed in degrees from 0 to 360 0(clockwiseas seen from above) or 0 to _360 0(counterclockwiseas seen from above). Changing this angle has the effectof rotating the building about its z-axis (vertical axis).GROUND-TCLEARNESS-NUMBERGROSS-AREAHEAT-PEAK-PERIODCOOL-PEAK-PERIODRul es:is ali s t of the local mean ground temperatures for eachmonth.

Its default is the sum ofthe floor areas of all conditioned spaces. This keywordis appropriate only to the subsequent generation of theBEPS (Estimated Building Energy Performance) Report inPLANT.

Th erefore,the user can choose to have the program ignore peaksthat occur, for example, when the building is unoccupied.The input is a list of two values, (min. hour, max. hour).Between and including these two hour values, hourly heatingpeaks will be calculated. Min. hour must be less than max.hour. The default is (1,24), which means that hourly peakswill be calculated for all day and all night. If SYSTEMSis permitted to size the secondary HVAC equipment, it willuse the peaks found within the stated hours.is analogous to HEAT-PEAK-PERIOD except that it concernshourly peak cooling loads.1. One and only one BUILDING-LOCATION instruction must be entered foreach separate LOADS program run. It should be input before anycommands that describe the building or anything associated with it(i.e., SPACE or BUILDING-SHADE).2. If the GROUND-T and CLEARNESS-NUMBER are not input, the values willbe taken from the weather files. (See Chap. VIII for instructionson how to add these to a weather file if they were not in theuser's original weather file.)3. If LONGITUDE, LATITUDE, or TIME-ZONE are not specified, the valueswill be taken from the weather file.III. 32 (Revised 5/81)
