Question 3

Which metric best describes how effectively a facility converts input energy into useful output?

Accepted Answer

Energy efficiency

Answer

Energy efficiency is the ratio of useful energy output to total energy input, indicating how well energy is converted to productive work.

Question 4

What is the primary purpose of a Measurement & Verification (M&V) plan in an energy project?

Accepted Answer

To document and verify energy savings achieved after implementation

Answer

An M&V plan establishes the methodology for measuring actual energy performance and verifying that projected savings are realized.

Question 5

The International Performance Measurement and Verification Protocol (IPMVP) Option A is best described as:

Accepted Answer

Key parameter measurement with stipulation of other parameters

Answer

IPMVP Option A measures key performance parameters while stipulating (assuming) values for less significant parameters to reduce measurement cost.
