The COMPUTE instructions for SYSTEMS and PLANT will cause the previouslyinput data to be used with the results from the new LOADS run.11. Schedul ing ConceptsSchedules are used to define specific conditions on an hour-by-hour basisfor the entire simulation. Schedules serve many functions, such as definingthermostat set pOints, indicating whether a piece of equipment is on or off,whether it is allowed to be on during a given hour, what fraction of itsmaximum capacity is permitted, etc.Schedules of varying complexity may be defined according to the requirementsof the user. In the normal mode, the three instructions used to definea schedule are the SCHEDULE, WEEK-SCHEDULE, and DAY-SCHEDULE instructions.(Advanced scheduling techniques are described in the Advanced SchedulingConcepts section.)The schedule definition process may be thought of as having three steps.The first step is to define one or more 24-hour schedules, using one or moreDAY-SCHEDULE instructions. These daily schedules are then assigned to particulardays of the week using the WEEK-SCHEDULE instruction. Finally, one ormore weekly sChedules are assigned to particular times of the year, using theSCHEDULE instruction.To illustrate this process, a schedule describing the occupancy of aschool building will be defined. The school is to be occupied from 8:00 AM to5:00 PM on weekdays during the school year. The school is to be unoccupiedall other times, including holidays during the school year.Examp le 1:The following instructions define such a schedule.OS-YES ; DAY-SCHEDULEOS-NO ; DAY-SCHEDULEWS-YES ; WEEK-SCHEDULEwS-NO ; WEEK-SCHEDULESCHOOL-SCHED ; SCHEDULEHOURS ;HOURS ;HOURS ;HOURS;DAYSDAYSDAYS ;THRUTHRUTHRU(1,8) VALUES (0.)(9,17) VALUES (1.)(18,24) VALUES; (0.)(1,24) VALUES (0.)(WD) DAY-SCHEDULE; OS-YES(WEH) DAY-SCHEDULE; OS-NO ..(ALL) DAY-SCHEDULE; OS-NO ..MAY 31, WEEK-SCHEDULE; WS-YESAUG 31, WEEK-SCHEDULE; WS-NODEC 31, WEEK-SCHEDULE; WS-YESThe day-schedule named OS-YES is entered to define a daily occupancyschedule for days when school is in session. The day-schedule named OS-NO isentered to define a daily occupancy schedule to be used on days when school isnot in session. The week-schedule named WS-YES is then entered to definewhich of the day-schedules is in effect for a given day of the week, and WS-NOis entered as a week-schedule indicating no occupancy for weeks when school isout. Finally, the schedule named SCHOOL-SCHED indicates that, during theschool year week-schedule WS-YES is to be used, but during the summer weekscheduleWS-NO is to be used.11.12 (Rev i sed 5/81)
