Energy audits Part 1: Commercial buildings
|Publication Date:||2 October 2014|
This Standard sets out minimum requirements for commissioning and conducting three prescribed types of commercial building energy audits that identify opportunities for cost effective investments to improve energy performance. These energy audits encompass all forms of energy used in commercial buildings and are undertaken by appropriately competent personnel either internal or external to the organization.
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 consumption in a commercial building is generally linked to the supply of comfort services, activities in the building and the use of utilities to support those activities, such as lighting, lifts or pumps. Energy audits in buildings may include the whole building or parts of the building or a specific technical system such as an HVAC system.
Requirements for industrial site energy audits are provided in AS/NZS 3598.2, while requirements for transport fleet energy audits are specified in AS/NZS 3598.3. Where auditing is to be carried out on an essentially commercial building that includes some industrial processes, the energy auditor may choose to apply AS/NZS 3598.2 to these industrial activities. If auditing warehousing sites as part of a distribution chain the energy auditor may choose to refer to AS/NZS 3598.3 for 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 buildings operated by commercial, industrial, and public-sector organizations, but not individual private dwellings. In most cases, implementing energy audit recommendations will achieve notable 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.
