The Project Impact Assessment with Measurement and Veriﬁcation (PIAM&V) method is based on internationally recognised measurement and veriﬁcation principles to calculate energy savings. It allows 'equipment level' energy savings to be deemed for up to ten years, using persistence and conﬁdence factors to discount initial certiﬁcate creation. In this method, the term ‘energy’ may refer to electricity, gas, or both.
IPART approves Measurement and Verification Professionals to be used by Accredited Certificate Providers to validate PIAM&V energy models.
IPART has published a PIAM&V Method Guide and the PIAM&V Method Requirements.
The Department of Planning, Industry and Environment (DPIE) has developed the Measurement and Verification (M&V) Operational Guide to help translate M&V theory into successful M&V projects. The guide consists of two process guidebooks, seven application-specific guidebooks, and an M&V project planning template.
As part of applying for accreditation, you must nominate the end-user equipment category (EUE) to be included in the accreditation and provide information to demonstrate your ability to implement the method for each EUE category. These documents could include a Measurement and Verification Plan (M&V Plan), Measurement and Verification Report (M&V Report) and spreadsheets/tools used to develop energy models and calculate energy savings.
Once accredited, the calculated energy savings for each implementation will be veriﬁed at audit.
You should refer to clause 7A of the Energy Savings Scheme Rule of 2009 (ESS Rule) and the PIAM&V Method Requirements to ensure that you understand how to calculate energy savings using the PIAM&V method.
We have developed the PIAM&V Method Requirements to increase clarity and certainty for ACPs, auditors and Measurement and Verification Professionals and to address changes in the ESS Rule (clauses 7A.5A and 7A.16) as a result of ESS (Amendment No.1) Rule 2020.
ACPs must comply with the PIAM&V Method Requirements from 30 March 2020 with the exception of requirements relating to clause 7A.5A which are subject to transitional arrangements. Clause 7A.5A relates to the review of Measurement Procedures in relation to Baseline Energy Models by an M&V Professional. Please refer to the PIAM&V Method Requirements and the ESS Rule that comes into effect on 30 March 2020 to ensure that you understand how the transitional arrangements work. A contravention of a PIAM&V Method Requirement by an ACP is a contravention of the Rule.
Please refer to our current consultations page for our response to submissions made during the PIAM&V Method Requirements consultation.
We have introduced end-user equipment (EUE) categories for use under the PIAM&V method. These categories are described in the PIAM&V Method Guide and ESS Notice 08/2018.
We have provided information to ACPs on an acceptable approach to top-up Energy Savings Certificate (ESC) creation under clause 7A.14 of the ESS Rule. The ESS Notice 02/2019 provides additional information about the acceptable approach to top-up ESC creation.
