.IDEAS.Controls.SetPoints.OccupancySchedule

Information

This model outputs whether the building is currently occupied, and how long it will take until the next time when the building will be occupied or non-occupied. The latter may be used, for example, to start a ventilation system half an hour before occupancy starts in order to ventilate the room.

The occupancy is defined by a time schedule of the form

  occupancy = 3600*{7, 12, 14, 19}

This indicates that the occupancy is from 7:00 until 12:00 and from 14:00 to 19:00. This will be repeated periodically. The parameter periodicity defines the periodicity. The period always starts at t=0 seconds.

Revisions

• February 7, 2025, by Jelger Jansen:
  Removed import statement. This is for IBPSA, #1961.
• March 25, 2021, by Michael Wetter:
  Integrated changes from Buildings for IBPSA, #1454.
• February 26, 2021, by Michael Wetter:
  Refactored implementation to use a function to compute the next time events.
  This is a work-around for Buildings, issue 2369.
• October 30, 2017, by Michael Wetter:
  Rewrote using equation rather than algorithm and removed assertion.
  This is for issue 844.
• September 11, 2012, by Michael Wetter:
  Added pre operator in when clause and relaxed tolerance in assert statement.
• July 26, 2012, by Michael Wetter:
  Fixed a bug that caused an error in the schedule if the simulation start time was negative or equal to the first entry in the schedule.
• February 16, 2012, by Michael Wetter:
  Removed parameter startTime. It was removed because startTime=0 would imply that the schedule should not start for one day if the simulation were to be started at t=-8760 seconds. Fixed bug that prevented schedule to start when the simulation was started at a time that is higher than endTime. Renamed parameter endTime to period.
• April 2, 2009, by Michael Wetter:
  First implementation.
