Project Impact Assessment with M&V
This page provides information about the Project Impact Assessment with Measurement and Verification method (PIAM&V).
About this method
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.

The Method Guide provides information required to conduct activities using this method of the ESS Rule. This version was published following amendments to the ESS Rule in April 2018.
Template Nomination Form
The Energy Savings Scheme Rule of 2009 allows an original energy saver to nominate an Accredited Certificate Provider as the energy saver in relation to the implementation of a recognised energy saving activity at a particular site. Such a nomination must be in the form and manner approved by the Scheme Administrator. Templates for nomination forms can be found on the Templates page.
Measurement and Verification Professionals
Under clause 7A of the ESS Rule, M&V Professionals used by Accredited Certificate Providers to validate PIAM&V energy models must be approved by IPART.
To submit an application, a completed M&V Professional Application Form and any supporting information should be emailed to: ESS_Applications@ipart.nsw.gov.au
M&V Professionals may be approved in relation to specific implementations of a recognised energy saving activity, or have ‘general’ approval to operate as an M&V Professional for various Accredited Certificate Providers. Details of people with general M&V Professional approval can be found here.

Calculating Energy Savings
A PIAM&V tool and guide has been developed by the Office of Environment and Heritage (external link). The Tool is especially useful as it is structured in a way that matches the requirements of this complex method. Use of the Tool is recommended, but is not mandatory.
IPART will check the inputs, calculations and supporting evidence when the Tool is submitted, as part of an application for accreditation. The energy savings output from the Tool will ultimately be veriﬁed at audit.
You should refer to clause 7A and the associated tables of the ESS Rule to ensure that you understand how to calculate energy savings using the PIAM&V method.
EUE categories under PIAM&V
We have introduced end-user equipment (EUE) categories for use under the PIAM&V method. The ESS Notice 08/2018 provides further information about the new categories and the transition process.
