The Energy Savings Measurement Guide (ESMG) provides guidance on how to estimate, measure, evaluate and track energy efficiency opportunities. It is primarily a technical guide, intended for company staff who will be involved in energy assessments and energy management. This includes engineers, managers and operational personnel. Written for companies that are investigating potential opportunities, it includes guidance on the development of business cases for energy projects and the determination of associated non-energy benefits. The guide provides a more focused discussion of measurement approaches and methods and further guidance on practical ways to ascertain accuracy. Coverage of statistical methods is enhanced, and brief worked examples have been added throughout. Discussion of energy baselines and performance indicators has been updated to incorporate lessons from international standards development. Guidance on financial evaluation approaches is also included.
The Guide will help companies to:
- improve their understanding of how to estimate and measure energy savings
- realise potential and financial savings by accurately quantifying the whole of business costs and benefits of an energy efficiency opportunity
- make the business case to key decision makers
- report accurately on savings identified and implemented.
The ESMG will assist companies to meet the key assessment and reporting requirements of the Energy Efficiency Opportunities program by accurately determining the energy savings of opportunities identified and implemented. It will also assist companies more generally to measure the energy and greenhouse savings available to them in a carbon constrained world.
The ESMG can be used to drill down into specific aspects of energy savings measurement, or be read and reviewed holistically. Practical guidance is provided by outlining numerous examples from five key industry sectors - mineral processing, mining, manufacturing, commercial buildings and transport.
The ESMG is an evolving document. It is updated based on industry use of the document in completing energy efficiency assessments. The guide incorporates feedback from industry and other expertise, and is updated to address emerging energy and greenhouse policies.
