2. Collect data on energy consumption and management; review energy-using equipment and production systems.
3. Inspect the site and prepare a measurement plan.
4. Carry out the planned measurements.
5. Analyse energy consumption patterns and efficiency in detail.
6. Develop feasible energy-saving measures.
7. Evaluate the economics of proposed energy-saving projects.
8. Prepare an implementation schedule.
9. Prepare the detailed energy audit report.

Indicative duration

• On-site work: approximately 7–10 days, divided into 2–3 visits.
