Hello Unmet Hours!

I am currently writing a measure to modify schedules in Open Studio and was wondering if it is possible to get time data when a certain set point or threshold is reached. for example, I would like to grab the time of day based on when the building was occupied; specifically the start time of the day.

I am still new to writing measures so any info would be extremely helpful.

Thank you

Let's say you grab a ScheduleRuleset from your Model:

In [1]:
sch = m.getScheduleRulesetByName("Large Office Bldg Occ").get
# Get the default day schedule
sch_day = sch.defaultDaySchedule
# Or get one of the schedule rules' day schedule
sch_rule = sch.scheduleRules[0]
sch_day = sch_rule.daySchedule

You could also get a specific schedule day from a list of dates: see SDK Doc for ScheduleRuleset::getDaySchedules

In [2]:
start_date and end_date are both inclusive, so to get a single schedule day for a specific date, do like this:

start_date = OpenStudio::Date.new(OpenStudio::MonthOfYear.new("Jan"), 3)
sch_days = sch.getDaySchedules(start_date, end_date)
sch_day = sch_days[0]

In all cases, you end up with a ScheduleDay object, which has two vectors: values and times. You can loop on them:

In [3]:
sch_day.times.each_with_index do |t, i|
   v = sch_day.values[i]
   puts "#{t} - #{v}"
end

Out[3]:
06:00:00 - 0.0
07:00:00 - 0.1
08:00:00 - 0.2
12:00:00 - 0.95
13:00:00 - 0.5
17:00:00 - 0.95
18:00:00 - 0.7
20:00:00 - 0.4
22:00:00 - 0.1
24:00:00 - 0.05

For the record, here's the content of my sch_day

In [4]: puts sch_day
Out[4]: OS:Schedule:Day,

@Julien Marrec and @ParticleSwarm there is also a sch_day.getValue()method that you pass a time into. This allows you to get a value for any time, even if that exact time doesn't exist in sch_day.times
