Engineering planning checklist

Compressed-Air Energy Audit

Estimate compressor power from free-air delivery and absolute pressure ratio, cross-check motor current, and translate the result into annual energy cost and Scope 2 emissions.

Use as a checklist, not an automated design workflow. Complete and verify each calculation independently. Only explicit carry-forward links move a compatible value; all other inputs remain your responsibility.

What this workflow covers

Estimate compressor power from free-air delivery and absolute pressure ratio, cross-check motor current, and translate the result into annual energy cost and Scope 2 emissions.

This 5-step checklist is intended for energy auditor. Confirm each linked calculator's units, formula, assumptions and operating limits before using the result in a project decision.

Sequence Execution
1

Compressed-Air Demand Sizing

Scope-limited calculation

Estimate required free-air delivery from connected end-use demand, diversity, leakage allowance, and future growth margin.

WORKFLOW INSTRUCTION:Convert connected end-use demand into required free-air delivery using measured diversity, leakage allowance, and growth margin.
2

Compressed-Air Compressor Power

Scope-limited calculation

Estimate compressor input power from free-air delivery, absolute pressure ratio, and compression efficiency.

WORKFLOW INSTRUCTION:Estimate the compressor input-power baseline from free-air delivery, absolute pressure ratio, and declared compression efficiency.
3

Motor Current Estimation

Calculate full-load line current (FLA) for 3-phase induction electric motors based on power rating and voltage.

WORKFLOW INSTRUCTION:Translate the compressor motor rating into a planning-level full-load current for feeder and nameplate cross-checking.
4

Plant Energy Consumption & Cost

Calculate daily, monthly, and annual electric energy consumption (kWh/MWh) and total electricity operating cost.

WORKFLOW INSTRUCTION:Convert compressor power, load factor, operating schedule, and tariff into an annual energy-cost baseline.
5

Industrial CO2 Carbon Emissions

Calculate Scope 2 greenhouse gas emissions from electricity consumption based on grid grid carbon intensity factor.

WORKFLOW INSTRUCTION:Convert the purchased electricity baseline into a documented Scope 2 emissions screen using the selected grid factor.
