Reports produced to date include residential, businesses and large mining operations, for example:
- Xstrata Nickel Cosmos Nickel Mine, 2009. Energy Audit (Level1)
- Tiwest Cooljarloo Mine, 2005. Level 1 Energy and GHG Emissions Report
- Alcock Browne-Neaves Group (14 home building companies), 2007. Level 2 Energy and CO2 Emissions Audit Reports
- Cleaner Climate, 2008. CO2 Lifecycle Estimates for Cruise Ships and Hotels
The audit reports comply with the relevant industry standard guidelines:
- AS 3598:2000 Energy Audits
- Energy Efficiency Opportunities Assessment Handbook
- World Business Council for Sustainable Development, corporate accounting and Reporting Standard
- National Carbon Offset Standard
CO2 emissions are usually assessed along with energy use. Level 2 reports, such as the mandatory Government Efficiency Opportunities (EEO) assessments include identification of on-site energy efficiency projects and cost-benefit analysis.
Energy and CO2 emissions assessment and management for a large industrial or commercial operation entails 7 steps:
Plan and scope the project – Meet with the responsible company managers to determine the actions required, when actions are undertaken and by whom and the financial and technical resources that are needed for the project. For example is the assessment for the mandatory Government NGERS or Energy Efficiency Opportunities (EEO) reporting or is it for the purpose of voluntary offsetting of emissions? Determine timetable for reporting and scope and boundaries of the assessment(s).
Plan Communications – Determine the key people within the organization, from senior management to operations, who need to be involved and informed. Link with company’s existing energy efficiency and emissions reduction policies and key production indicators; if these are not in place, initiate them. What are the lines of communication during the audit and for ongoing energy and emissions management? How will this be done, for example monthly team meetings?
Assess energy use – Collect and analyse data quantifying energy use, consumption of goods and services that have been determined to be within the scope of the audit. Understand how and where energy is used on the site; produce energy – mass balance diagram. Identify where energy monitoring is insufficient and how it needs to be improved
Identify energy efficiency opportunities – Meetings and workshops with the company’s energy managers and external experts to identify, cost and prioritise energy efficiency and emissions reduction opportunities.
Produce Energy and CO2 Emissions Report – Energy management team checks the baseline energy / consumption data, prioritized opportunities for action and endorses the final report.
Detailed investigations - Plan and commence additional energy tracking and data analysis recommended in the report. Through meetings and advice from internal and consultant experts, define costs, benefits and business cases for each energy efficiency opportunity.
Implementation, tracking and communication – The site energy management team continues to monitor and record of energy use as outlined in the assessment report(s). Energy and emissions saving projects are implemented and reported on through the identified management channels.
