	Calculates annual compressed air consumption and flow rate using the flow meter method.
CompressedAirReductionOutput	bagMethodReduction (const BagMethodData &data, int hours_per_year, int units)
	Calculates annual compressed air consumption and flow rate using the bag method.
CompressedAirReductionOutput	pressureMethodReduction (const PressureMethodData &data, int hours_per_year)

Detailed Description

Provides a function-based API for estimating annual compressed air consumption, energy use, and cost savings for compressed air reduction measures identified during an energy treasure hunt or efficiency assessment. Supports four measurement methods: flow meter, bag method, orifice/pressure method, and other. Two utility types are supported: compressed air (cost per unit volume) and electricity (cost per kilowatt-hour, derived via compressor specific power).

Enumeration Type Documentation

MeasurementMethod

enum class compressed_air_reduction::MeasurementMethod

strong

Enumerator
FlowMeter	Flow meter method — reads flow rate directly from an installed flow meter.
Bag	Bag method — estimates flow rate by timing how long it takes to fill a known-volume bag.
Pressure	Orifice/pressure method — calculates flow rate from nozzle type and supply pressure.
Other	Other method — uses a directly supplied annual consumption value.

UtilityType

enum class compressed_air_reduction::UtilityType

strong

Enumerator
CompressedAir	Compressed air utility — cost based on air consumption \([\unit{\dollar\per\cubic\foot}]\).
Electricity	Electricity utility — cost based on compressor electricity draw \([\unit{\dollar\per\kilo\watt\hour}]\).
