.space_cooled?(space) ⇒ Boolean
Determines cooling status. If the space’s zone has a thermostat with a minimum cooling setpoint above 33C (91F), counts as cooled.

.space_get_design_internal_load(space) ⇒ Double
Determine the design internal load (W) for this space without space multipliers. This include People, Lights, Electric Equipment, and Gas Equipment. It assumes 100% of the wattage is converted to heat, and that the design peak schedule value is 1 (100%).

.space_hours_of_operation(space) ⇒ Hash
add related related to space_hours_of_operation like set_space_hours_of_operation and shift_and_expand_space_hours_of_operation
ideally these could take in a date range, array of dates and or days of week. Hold off until need is a bit more defined.
If the model has an hours of operation schedule set in default schedule set for building that looks valid it will report hours of operation. Won’t be a single set of values, will be a collection of rules note Building, space, and spaceType can get hours of operation from schedule set, but not buildingStory
Retrieves the default occupancy schedule assigned to the space @example: {
schedule: space hours_of_operation schedule,
[rule index, -1 is default day]: {
hoo_start: [float] rule operation start hour,
hoo_end: [float] rule operation end hour,
hoo_hours: [float] rule operation duration hours,
days_used: [Array] annual day indices
}
}

.spaces_get_occupancy_schedule(spaces, sch_name: nil, occupied_percentage_threshold: nil, threshold_calc_method: 'value') ⇒ <OpenStudio::Model::ScheduleRuleset>
This method creates a new fractional schedule ruleset. If occupied_percentage_threshold is set, this method will return a discrete on/off fractional schedule with a value of one when occupancy across all spaces is greater than or equal to the occupied_percentage_threshold, and zero all other times. Otherwise the method will return the weighted fractional occupancy schedule.

.spaces_hours_of_operation(spaces) ⇒ Hash
If the model has an hours of operation schedule set in default schedule set for building that looks valid it will report hours of operation. Won’t be a single set of values, will be a collection of rules this will call space_hours_of_operation on each space in array loop through all days of year to make as many rules as ncessary expand hours of operation. When hours of operation do not overlap for two spaces, add logic to remove all but largest gap
