What is 'measurement and verification' (M&V) as it applies to ESCO commissioning projects?
Answer: The process of measuring energy use before and after improvements to calculate and verify actual savings
M&V quantifies the actual energy savings achieved so the ESCO can demonstrate performance against guaranteed savings.
Which pre-design commissioning activity does ASHRAE Guideline 0 recommend to most improve commissioning effectiveness?
Answer: Developing the Owner's Project Requirements (OPR) before design begins
Establishing the OPR before design begins ensures designers have clear performance targets and reduces costly late-stage changes.
What does 'near-zero energy drift' mean as an outcome goal of an ESCO's ongoing commissioning program?
Answer: Maintaining building energy performance close to the optimized post-commissioning baseline over time by continuously correcting small deviations
Ongoing commissioning prevents the gradual degradation in efficiency that typically occurs after a one-time commissioning event.
Under LEED v4, how many points can a commercial building earn through Enhanced Commissioning (EAc1)?
Answer: Up to 6 points
LEED v4 Enhanced Commissioning offers up to 6 points across fundamental, enhanced, and monitoring-based commissioning options.
What is the 'Basis of Design' (BOD) document and who is responsible for creating it?
Answer: A written explanation of the design assumptions and system selections created by the design engineer to document how the OPR will be met
The BOD documents the engineer's design decisions and assumptions so the commissioning authority can verify that systems are built and operated as designed.
In ESCO projects, what is the main advantage of including commissioning as part of a performance contract rather than as a standalone service?
Answer: Commissioning findings can identify additional ECMs, the guaranteed savings cover commissioning costs, and M&V verifies the full project performance
Bundling commissioning with ECMs allows RCx findings to feed directly into the project scope, and the performance guarantee framework ensures rigorous M&V for all measures.
