Compressed Air Energy & Leakage Audit Pro — Excel Workbook

A professional, formula-driven Excel audit tool designed for energy managers, maintenance engineers, compressed-air auditors, facility teams, and manufacturing plant management.

This workbook helps you evaluate compressed-air system performance, identify leakage losses, estimate energy and financial savings, compare compressors, track improvements, and present audit results clearly to management.

Instead of using a basic spreadsheet with hidden calculations, this workbook is structured as a complete compressed-air audit system, with transparent formulas, editable assumptions, validation checks, KPI dashboards, and management reporting.

Built for real-world auditing

The workbook includes input validation, error checks, warnings, conditional formatting, structured Excel tables, frozen panes, editable assumptions, and formula-driven calculations.

It is designed so that an auditor can enter plant data without needing to modify formulas, while the calculation methodology remains visible and auditable.

Includes sample data

The workbook comes with a realistic sample manufacturing-plant dataset so buyers can immediately see:

• How the calculations work

• What the dashboard looks like

• How compressor comparisons work

• How leakage opportunities are ranked

• How management results are presented

Ideal for

Manufacturing plants • Energy audits • Compressed-air audits • Maintenance departments • Energy management • Industrial utilities • Sustainability programs • ISO 50001 energy reviews • Compressor optimization • Leakage reduction projects
