Energy Star is the nation’s most widely used and recognized energy reporting and bench marking system, but it is seldom considered to be a method of measurement and verification (M&V) of savings. This study investigates almost 1,000 buildings that underwent energy conservation initiatives while simultaneously receiving Energy Star ratings and IPMVP Option C M&V reports. It correlates the increase in Energy Star ratings with the M&V results for matching time periods. If an increase in Energy Star rating can be shown to reliably mirror the results of a much more comprehensive -- and expensive -- IPMVP M&V analysis, then Energy Star ratings can be used as a low-cost, simple M&V method when the cost of a more intensive analysis is not justified. ISO 50015:2014 does not mandate any particular M&V method but rather puts the burden on the M&V practitioner to document the method and the rationale for its selection in the M&V Plan. Accordingly, an M&V Plan can be ISO 50015 compliant by using a trusted alternative to IPMVP, an approach that could be very important for many organizations.
