Devising a methodology to measure and verify savings from environmental upgrade agreements, balancing accuracy with compliance costs.

The challenge

The NSW Department of Environment and Heritage wanted an effective and accurate way to measure and verify the savings from buildings that had made improvements under Environmental Upgrade Agreements(EUA).

Using a case study building, they engaged Common Capital to devise an effective measurement and verification (M&V) methodology.

Our approach

A building that had used EUA finance to upgrade to more energy efficient lighting and air conditioning was selected as an example project.

Common Capital used formal measurement and verification to statistically quantify what the savings were. We then trialled different statistical approaches and looked at the feasibility of using them, balancing how accurate they were against the compliance costs of using them.

In addition, Common Capital explored if the savings could be transformed into Energy Savings Certificates under the NSW Energy Savings Scheme (ESS), by using methodologies consistent with the ESS rules.

The outcome

We were able to identify a commercially feasible approach to verifying savings from EUA projects.

The findings from the example project were also able to be used by the building owner to create and sell Energy Savings Certificates under the NSW Energy Savings Scheme.
