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.
A PIAM & V Tool and Guide has been developed by the Office of Environment and Heritage. 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.
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.
