Enhancement Request

Deprecate ElectricEquipmentITEAirCooledDefinition's "Watts per Zone Floor Area" and replace with "Watts per Space Floor Area"

Detailed Description

cf #5090 (comment)

Possible Implementation

Straightforward.

[jmarrec]

The schedules should never have been optional, but defaulted to always on:

OpenStudio/src/model/ElectricEquipmentITEAirCooled.hpp

Lines 52 to 60 in c48911e

	// Return the Design Power Input Schedule. If not specified, default to always 1.
	boost::optional<Schedule> designPowerInputSchedule() const;
	bool isDesignPowerInputScheduleDefaulted() const;
	// Return the CPU Loading Schedule. If not specified, default to always 1.
	boost::optional<Schedule> cPULoadingSchedule() const;
	bool isCPULoadingScheduleDefaulted() const;

but this would be an API break now

[jmarrec]

Seems like the "Number of Units" field was omitted from the implementation. I think it's replaced by Multiplier to match other objects

[jmarrec]

All other SpaceLoadInstances use the same terminology powerPerFloorArea / getPowerPerFloorArea but this one doesn't, it uses wattsperZoneFloorArea

[jmarrec]

Setters don't clear the other field. setWattsperFloorArea should clear the Watts Per Unit one, and vice versa
