AS NZS 3598.2:2014 pdf free.Energy audits Part 2: Industrial and related activities
The level of accuracy of energy savings and financial costs and benefits from energy performance improvement actions. Three levels are classified as follows:
(a) Broad estimates- Energy savings and capital costs estimated based on facility-level energy data and information from similar projects previously implemented or based on simple engineering calculations/estimations to a lower degree of accuracy. These are generally based on rules of thumb without any preliminary design work. Suitable;for smaller projects with short paybacks and low risks.
(b) Medium accuracy- Energy savings quantified using site and energy analysis as described for the Type 2 audit,including consideration of site-specific data,operations and other relevant context, with consideration of the detailed energy balance. Capital costs estimated based on a summation of major cost items based on the configuration of systems and equipment necessary to implement the energy savings measure.
(c) Higher accuracy- Energy savings quantified using site and energy analysis as described for the Type 3 audit, including consideration of site-specific data,operations and other relevant context, with consideration of the detailed energy balance developed using the additional monitoring data. Capital costs estimated from contractor quotes and/or detailed cost estimates based on specific equipment selections and schematic designs. Alternatively the level of accuracy required by the company’s capex or opex process may be applied.
NOTE: Refer to Appendix H, Paragraph H7.Industrial sites have strict occupational health, safety and hygiene requirements that will vary from site to site. The auditor shall demonstrate a commitment to and an understanding of industrial health and safety and shall comply with all occupational health and safety (OHS) instructions from the organization.
The auditor shall also demonstrate the ability to provide the level of analysis required to effectively quantify the energy savings, costs and benefits obtainable from the industrial processes being audited. For example, for a large compressed air system the auditors should be able to analyse the thermal performance of the compressed air system as well as the performance of the compressor and the management of air consumption.AS NZS 3598.2 pdf free download.
