Overview of Measurement and Verification

Measurement and Verification (M&V) is the process of determining energy savings derived from an energy performance upgrade project or programme.  It is particularly important in demonstrating to the funders of a project what the savings have been from their investment in improving energy performance,

Internationally it has been recognised that a standard method for measuring and verifying energy savings is needed and the International Performance Measurement and Verification Protocol (IPMVP) was established in 1996.  EMANZ works with EVO, the International body that oversees the IPMVP and the American Society of Energy Engineers (AEE) to provide the Certified Measurement and Verification Professional (CMVP) training and certification programme. 

Model Measurement and Verification Reports

Model M&V reports (below) have been compiled by EMANZ, in partnership with EECA, to provide guidance for energy efficiency practitioners and other industry stakeholders on how to align their Measurement and Verification (M&V) processes with the globally recognised International Performance Measurement and Verification Protocol (IPMVP).

The key role of IPMVP is to present a consistent framework and ‘language’ to be used in determining ‘savings’ achieved after the implementation of an energy efficiency or conservation project.  It’s describes a series of non-prescriptive, flexible and realistic approaches to M&V activities, while upholding the key principles of:

  • Accuracy
  • Completeness
  • Conservativeness
  • Consistency
  • Relevance
  • Transparency

Specific to the New Zealand context, M&V has an important role in a number of energy efficiency activities. Where government funding (eg. via EECA) has been applied to assist the uptake of energy efficiency projects, providers are required to demonstrate that performance guarantees are being achieved. Similarly, in the emerging Energy Performance Contracting market, M&V plays a critical role in the ‘accounting’ of energy and cost savings and subsequent contractual transactions.

M&V activities must be commercially realistic, and the IPMVP recognises that a successful M&V programme delicately balances the need for accuracy with the costs of gathering, analysing and reporting on measured data.  For that reason, EMANZ has developed different model M&V reports for various ‘scales’ of project.

 
Small Project
Medium Project
Large Project
Annual Savings
$0 to $15,000
$15,000 to $50,000
$50,000 to $110,000
Nominal Project Value (@ 5 year Payback)
Up to $75,000
Up to $250,000
Up to $550,000
Indicative M&V Budget
Up to $1,500
Up to $5,000
Up to $11,000

There is an element of professional judgement required from practitioners when selecting an appropriate M&V strategy for a specific project. This includes consideration of the expectations of the client and any third-party funding partners. It is also expected that a project which exceeds the indicated scale of a Large Project would warrant a completely tailored M&V strategy, and the requirements for planning and reporting will likely be more stringent than indicated by the model reports here.

The IPMVP framework has four fundamental methods of determining savings. Three of these apply to the vast majority of energy efficiency projects undertaken in New Zealand.

  • Option A – Retrofit Isolation:  Key Parameter Measurement
  • Option B – Retrofit Isolation:  All Parameter Measurement
  • Option C – Whole Facility

These model M&V reports therefore cover the full range of project scales and IPMVP options.

Option A - small project Option B - small project Option C - small
Option A - medium project Option B - medium project Option C - medium project
Option A - large project Option B - large project Option C - large project
