scope:

This Standard sets out minimum requirements for commissioning and conducting three prescribed types of industrial energy audits that identify opportunities for cost effective investments to improve energy performance of industrial facilities (including quarries, mines and upstream petroleum operations). These energy audits encompass all forms of energy used in organizations and are undertaken by appropriately competent personnel either internal or external to the organization.

On an industrial site, an energy audit is an important tool to facilitate an organization to manage its energy performance. It can be part of a site wide energy management system.

Requirements for each specified type of audit are designed to meet the organization's business needs, and provide sufficient analytical rigour to provide a degree of confidence in the results that is appropriate to meet these business needs.

Energy consumed in an industrial process or service site is generally linked to the operation of production services, utility services supporting the production activities, and other ancillary operations. There are differences in processes and utilities used and energy uses for different operations. An industrial site can include one or more production lines, laboratories, research centres, packaging and warehouse sections with specific operational conditions.

Conveying of materials or products within the process and other stationary material handling systems will normally be within the scope of the audit. The use of vehicles within the process may or may not be within the scope of the audit. The audit boundary may include mobile on-site transport equipment and transport or storage external to the site. Organizations are referred to AS/NZS 3598.3 for audits of major on-site vehicle transport operations, such as off-road mine haulage, as well as transport operations using public transport infrastructure.

Requirements for commercial building energy audits are provided in AS/NZS 3598.1, while requirements for transport fleet energy audits are specified in AS/NZS 3598.3.

Where auditing buildings associated with the industrial site, the energy auditor may choose to apply AS/NZS 3598.1. If on-site transport on an industrial site is included in the scope of the energy audit, the energy auditor may choose to apply AS/NZS 3598.3 to this activity.

The energy audit process is presented as a simple chronological sequence, but this does not preclude repeated iterations of certain steps. It applies to industrial and public-sector organizations, but not individual private dwellings.

Energy audits should be undertaken every 3 to 5 years or subsequent to any significant plant, equipment or process upgrades. In most cases, implementing energy audit recommendations will achieve cost savings.

This Standard does not deal with energy audit program/scheme properties such as program administration, training of energy auditors, and energy auditors' tools.
