CEA Measurement & Verification (M&V) Protocols Flashcards

Which organization publishes the International Performance Measurement and Verification Protocol (IPMVP)?

Answer: EVO (Efficiency Valuation Organization)

The Efficiency Valuation Organization (EVO) publishes and maintains the IPMVP, the globally recognized framework for M&V of energy savings.

In M&V terminology, what is the 'baseline period'?

Answer: The reference period before efficiency measures are implemented, used to establish pre-retrofit energy use

The baseline period represents energy consumption before efficiency measures are applied, serving as the reference against which post-retrofit savings are measured.

IPMVP Option A (Retrofit Isolation – Key Parameter Measurement) involves what approach?

Answer: Measuring some parameters and stipulating others based on short-term or historical data

Option A measures key performance parameters (e.g., power draw) while stipulating less critical parameters (e.g., operating hours) from historical data.

IPMVP Option B (Retrofit Isolation – All Parameter Measurement) differs from Option A in that it:

Answer: Continuously meters all relevant parameters of the isolated system rather than stipulating any

Option B requires continuous measurement of all parameters (power and hours) for the specific system, providing higher accuracy than Option A but at greater monitoring cost.

What is a 'stipulation' in the context of IPMVP M&V?

Answer: A value assumed or agreed upon rather than directly measured, used to simplify M&V

A stipulation is an agreed-upon value for a parameter (like operating hours) that is not directly measured, accepted by both parties to reduce M&V costs.

Which IPMVP option is most appropriate when energy savings cannot be attributed to isolated systems and whole-building metering is required?

Answer: Option C

Option C (Whole Facility) uses utility meter data to track savings at the whole-building level, suitable when measures affect overall facility consumption.
