Energy usage is dynamic; it changes based on multiple factors. Unpacking the ‘noise’ and determining before (Baseline) and after (Reporting Period) avoided energy use (Savings) requires a thorough approach. Building the correct accounting systems before a set of upgrades are implemented is critical. Though a well-designed Measurement and Verification (M&V) process, physical measurements and metering data can then be designed from the start to provide a high level of confidence in savings estimates.
The International Performance Measurement and Verification Protocol (IPMVP) is the global standard used to account for investments in energy efficiency. The principles of M&V followed are that savings projects are accurate, conservative, complete, consistent, relevant and transparent. Having a Certified Measurement and Valuation Professional (CMVP) undertake M&V ensures you follow best practices in investment analysis of energy savings projects.
