Project Impact Assessment with Measurement and Verification tool

The Energy Savings Scheme (ESS) allows Energy Savings Certificates (ESCs) to be created for completed energy efficiency projects. ESCs have monetary value and can be traded in the market. A Recognised Energy Saving Activity (RESA) must be created to claim certificates, and this tool assists users to create a RESA using the Project Impact Assessment with Measurement and Verification (PIAM&V) method.

The PIAM&V method utilises internationally recognised measurement and verification principals to verify energy savings. It allows 'equipment level' energy savings to be deemed for up to ten years, using accuracy and decay factors to ensure an accurate number of certificates are created.

The PIAM&V Tool and User Guide will help you calculate energy savings for a RESA using the PIAM&V method.

About the Project Impact Assessment with Measurement and Verification tool

The PIAM&V Tool is designed to be completed progressively throughout the measurement and verification process. It will estimate energy savings once the project has been implemented and an operating model developed.

Download the tool

Version 2.2 of the tool was released on 10 May 2017. It incorporates changes to Effective Ranges in the ESS Rule that came into effect on 28 April 2017. Several bugs have been fixed in this version of the tool.

The tool can:

  • calculate energy savings for both electricity and gas saving projects (including fuel switching activities)
  • establish energy models from both regression analysis and an estimate of the mean
  • calculate decay factors using the persistence model.

The minimum requirements to run the tool are:

  • Windows 7 operating system
  • Microsoft Office Excel 2010.
