AEE Certified Measurement and Verification Professional (CMVP)

In an M&V project, what is the primary purpose of defining the measurement boundary?

• ATo identify which energy uses and effects are included in the savings calculation
• BTo choose the lowest-cost meter available for the project
• CTo eliminate the need for a baseline period
• DTo guarantee that no adjustments will be required

Which condition best supports using a baseline as the reference for savings?

• AThe baseline period is undocumented but long enough
• BThe baseline represents normal operation before the energy management activity
• CThe baseline is chosen after the highest savings result is known
• DThe baseline excludes all variables that affect energy use

A routine adjustment is most appropriate when a savings calculation must account for:

• AA one-time building expansion not represented in the model
• BWeather changes that are expected to affect heating and cooling energy

Which is the clearest example of a non-routine event in a whole-building M&V analysis?

• DUse only the month with the lowest production as the baseline

Why should external requirements, such as a utility incentive rule, be identified before finalizing an M&V approach?
