Every day this week I am uploading a poster taken from the contents of my book on energy and resource efficiency – to help fellow practitioners communicate the benefits and processes that will unlock value in their organizations and sustain change.

Today is day 3 and I am providing a flowchart to enable folks to select the most appropriate Measurement and Verification (M&V) technique.

Attracting third-part funding or investment into energy efficiency measures requires us to be able to unambiguously assess the savings that have been made, out of which the repayments are usually taken. This involves being able to calculate what is known as the “counterfactual”, i.e. what would have happened if we hadn’t made the investment.

Fortunately some clever folks at the IMVP, FEMVP and Investor Confidence Project have developed formal methods to undertake these calculation.
