Schedules
Schedules provide you with the ability to modify various parameters based on the time of day and day of the week. Schedules apply when performing both transient and steady-state simulations. The steady-state simulation date and time will be used to access the schedule values. You use schedules to provide a fractional multiplier to parameters at times which you define. You can schedule items such as the flow through airflow paths, the outdoor air intake of simple air handling systems, contaminant source/sinks, the location of an occupant within a building and zone temperatures.
CONTAM provides occupant schedules and non-occupant schedules which are split up into week schedules which are in turn made up of one or more day schedules. Non-occupant week schedules can be associated with as many schedulable items as you need, whereas occupant week schedules can only be applied to a single occupant. Only non-occupant schedules can be shared between CONTAM project files using the CONTAMW Library Manager. Occupant schedules can not be shared between projects, because they are dependent on the level and zone names which may be different between projects.
