measurement & verification

balance M&V cost & accuracy

verify energy savings

Using measurements and trends, we verify your project saves energy and costs as expected.

For utility programs, we ensure incentive dollars are spent only on projects that achieve savings.

Our experience enables us to choose the right level of M&V for your project or program.

normalized metered energy consumption (NMEC)

With smart meters increasing, more buildings have high-resolution consumption data making diagnostics, and reliable whole building M&V feasible in many cases.

This approach to site-specific, meter based M&V has a few names:

  • advanced measurement and verification (AMV),
  • M&V 2.0, and
  • metered energy consumption (NMEC) in California.
lower cost
shorter monitoring
rapid feedback
increased accuracy

We are pioneers in using whole-building, interval meter data to track and verify energy project savings, have authored numerous guidelines and implemented these approaches for many utility programs.


We developed an open-source r package, called nmecr, which is free to use.

Use it to perform M&V when analyzing site-level, meter based, energy savings.

Our goal is to facilitate adoption of these methods for encouraging deeper energy efficiency retrofit projects.
