Levels of Energy Audit

ASHRAE has provided four levels of the audit. They are:

Energy Audit

1. Bench Marking or Level 0 — This level of audit involves a study to understand whether further analysis is required or not.
2. Walk Through Audit or Level I — This audit includes a preliminary assessment of the energy efficiency of the building. As a result, the consultant can come upon simple and cost-efficient measures for improvements.
3. Detailed to General Energy Audit or Level II — The consultant conducts a comprehensive survey of the facility.
4. Investment-Grade Audit or Level III- This audit involves a detailed engineering study with a focus on modifications.

Generally, the industrial electrical design consultant providing the audit services, recommends the level of audit.

To conclude, the energy conservation and energy audit is a way of keeping operating expenses under control. A professional industrial electrical design consultant helps in the audit of a facility. Also, it is essential to consider the entire facility in a holistic way.
