CEA CEA Measurement & Verification (M&V) Protocols 1 — Questions and Answers
Question 1: Which organization publishes the International Performance Measurement and Verification Protocol (IPMVP)?
- ASHRAE
- EVO (Efficiency Valuation Organization) (Correct answer)
- DOE (Department of Energy)
- EPA (Environmental Protection Agency)
Correct 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.
Question 2: In M&V terminology, what is the 'baseline period'?
- The period after energy efficiency measures are installed
- The reference period before efficiency measures are implemented, used to establish pre-retrofit energy use (Correct answer)
- The period during equipment installation
- The financial payback period for the project
Correct 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.
Question 3: IPMVP Option A (Retrofit Isolation – Key Parameter Measurement) involves what approach?
- Metering all energy flows in and out of the entire facility
- Measuring some parameters and stipulating others based on short-term or historical data (Correct answer)
- Using a calibrated simulation model to determine savings
- Comparing whole-facility utility bills before and after retrofit
Correct 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.
Question 4: IPMVP Option B (Retrofit Isolation – All Parameter Measurement) differs from Option A in that it:
- Uses whole-facility metering
- Continuously meters all relevant parameters of the isolated system rather than stipulating any (Correct answer)
- Relies entirely on stipulated values
- Uses a calibrated simulation model
Correct 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.
Question 5: What is a 'stipulation' in the context of IPMVP M&V?
- A legal requirement mandating energy savings
- A value assumed or agreed upon rather than directly measured, used to simplify M&V (Correct answer)
- A metering device installed to track energy use
- A penalty clause for not meeting savings targets
Correct 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.
Question 6: Which IPMVP option is most appropriate when energy savings cannot be attributed to isolated systems and whole-building metering is required?
- Option A
- Option B
- Option C (Correct answer)
- Option D
Correct 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.
