.create_annual_ruleset_schedule(model, name, type, hourArrayValues, start_date = "Jan-1", end_date = "Dec-31") ⇒ Object

Creates a new ruleset schedule object. This is the basic schedule component used in openstudio. name = string: name of schedule type = TEMPERATURE, ON_OFF, FRACTION hourArrayValues = a 3 x 24 array representing week, sat and sun hours. examples: hourArrayValues =

  [18,18,18,18,21,21,21,21,23,23,23,23,23,23,21,21,21,18,18,18,18,18,18,18],#Weekday

or if you need a constant temperature you can use this shorthand method.

heat_setpoint_array =
  [
  Array.new(24){21}, #Weekday
  Array.new(24){21}, #Sat
  Array.new(24){21}, #Sun
