3 Industry Descriptions related to M&V Measurement & Verification is the process of using measurements to reliably determine actual saving created within an individual facility by an energy management program. [Ref: IPMVP Vol. 1, 2012, Ch 2, p. 4] transparently, reliably and consistently reporting a project s savings. [Ref: IPMVP Vol. 1, 2012, p. viii] g defines the measurements and computations to determine payments or demonstrate t compliance with a guaranteed level l of performance. [Ref: IPMVP Vol. 1, 2012, App. D, p. 117] to improve savings, achieve greater persistence of savings over time, and lower variations in savings [Ref: IPMVP Vol. 1, 2012, Ch 2, p. 5] 3

4 Industry Descriptions related to M&V...M&V can:. Reduce uncertainties to reasonable levels Monitor equipment performance Find additional savings Improve operations and maintenance (O&M) Verify that t the cost savings guarantee is met Allow for future adjustments, as needed [M&V Guidelines: Measurement and Verification for Federal Energy Projects, Version 3.0, April 2008, p.2-1] reliably measuring the energy and demand d savings due to building energy management projects. [ASHRAE Guideline , p. 4] A critical aspect of the savings measurement for this purpose p is its timeliness. [ASHRAE Guideline , p. 4] 4
