This guide was developed to assist companies with undertaking an energy efficiency assessment on a sample that is reasonably representative of their population of similar sites, fleets, technologies or processes. This type of assessment is also referred to as a representative assessment (RA). The purpose of the guide was to assist in determining whether an RA was appropriate for a corporation’s circumstances as well as provide guidance on how to conduct an RA to the level of accuracy required by the Energy Efficiency Opportunities (EEO) program.

This report details the results from a survey of C-level executives who were asked for opinions and attitudes towards energy efficiency.

Information was gathered through a quantitative research among executives from organisations participating in the Department of Resources, Energy and Tourism’s Energy Efficiency Opportunities (EEO) Program. A total of 60 of 220 companies participating in the program at the time were included in the survey.

The purpose of these case studies is to demonstrate how systems optimisation can be used to improve energy efficiency and productivity in a wide range of industrial applications. They were developed through companies' participation in the Energy Efficiency Opportunities (EEO) program. Examples from 3 companies highlight different aspect of systems optimisation:

This document details roles and skills required to undertake, report on and implement the findings of rigorous energy efficiency assessments for large energy users. It is the result of research primarily based around the assessment requirements of the Energy Efficiency Opportunities (EEO) program. The findings also have relevance for companies participating in state government energy assessment programs and other companies wishing to improve their energy efficiency performance.

This is a guide on how to effectively develop an energy-mass balance (EMB), a method for accounting for the energy and material flows  for a commercial building and its processes. It was designed for corporations to meet the requirements of the Energy Efficiency Opportunities (EEO) program but can used by any large energy user.

This handbook provides guidance for large energy users on how to effectively conduct an energy efficiency assessment.  It draws on the practical experiences of companies and consultants that have undertaken effective energy assessments and can help corporations plan and implement assessments in a way that will optimise business outcomes. The handbook was designed for corporations to meet the requirements of the Energy Efficiency Opportunities (EEO) program but can be used by any large energy user.

A summary of the roles and responsibilities of key figures within a large organisation that are relevant to corporate energy management.

The positions for which these roles are summarised are:

• chief financial officers
• environmental health and safety professionals
• mechanical or electrical engineers
• technicians and tradespeople
• sustainability officers

At the McIvor Road Vet Clinic in Victoria, an increase in demand for its services led to installation of new equipment. Energy bills went ‘through the roof’, and service demands meant switching equipment off was not an option. Instead, the Clinic installed additional insulation and a 10kW solar PV system, switched from halogen to light emitting diodes (LEDs), and installed a solar boosted, gas hot water system. Within 12 months, the Clinic’s energy use has been cut by 50%, saving $5000 per annum.

The owners of Bendigo’s The Good Loaf Sourdough Bakery & Café regularly review the businesses energy practices. This factsheet details a number of changes made in the last few years, which included:

• installing energy-efficient compact fluorescent lamps (CFLs)
• a timer on the baking oven
• zoning the bakery’s lighting 

These changes, and others detailed in this factsheet, have meant that despite the business growing 10% in recent years, energy costs have remained stable. A cost saving of $2000 per annum.

Golden North is a manufacturer of premium ice cream and frozen yoghurt. Its South Australian facility at Laura consumes 6930 gigajoules (GJ) of electricity per annum, about 75% of which is used by the refrigeration plant. Energy assessment identified numerous areas for savings through energy efficiency improvements, including replacing inefficient compressors with a single crew compressor (and using variable speed drives to ensure it runs efficiently); installation of hot water exchangers for oil cooling and installing variable speed fans.
