What does the M&V process entail?

The Measurement & Verification process followed at Power-Star adheres to IPMVP (International Performance Measurement & Verification Protocol). This is the internationally accepted standard in M&V and allows for accurate, conservative and repeatable results. Key aspects include the definition of a measurement boundary, determination of the static factors and interactive factors influencing the measurement, and appropriate baseline conditions and measurement. The M&V process would thus follow this typical path:

  • Initial inspection of site including the area where the ECM (Energy Conservation Measure) will be deployedmeasurement & verification
  • Determination of the M&V plan, including expected accuracy
  • Installation of required measurement equipment
  • Gathering of baseline information (The IPMVP does allow for M&V where no baseline data is available, but this is typically avoided where possible)
  • Deployment of ECM by the client
  • Post-deployment measurement
  • Preparation of M&V report
  • Post-project discussion with client detailing the results of the investigation



The Power-Star proprietary meter conforms to IEC safety standards which mean it has been tested and verified for intrinsic safety in industrial measurement.

  • The meter is a Class 1 data logger and is therefore tested and calibrated to the appropriate levels.
  • The company employs 2 Certified Measurement and Verification professionals (CMVP). The CMVP process provides certification for the professional to engage in M&V processes using IPMVP (International Performance Measurement and Verification Protocol).


The cost structure for Power-Star main meters is well defined and available by contacting Power-Star directly. The reason is that the cost will depend greatly on the complexity of the installation and so a proposal is custom designed for each client’s needs. In terms of M&V for official purposes, typical costs are 5-10% of project costs. This varies drastically depending on the method chosen for evaluating a project. The three main components of the cost are as follows:

  1. Development of the M&V plan. This component is typically priced on professional time spent, as the complexity may vary drastically from project to project.
  1. Installation of measurement equipment Depending on the complexity of the measurement required (and in some cases no additional measurement would be required) this can vary from zero cost (when we use council billing or computer modelling) to significant (when we have to measure over long periods of time, or with very low resolution, or for certain variables).
  1. Preparation of an M&V report. This component is once again typically priced on professional time spent.
