CEM Methods and Strategies 3

Question 1

Which measurement and verification (M&V) option under IPMVP is MOST appropriate when it is difficult to isolate individual measure savings?

Accepted Answer

Option C — Whole Facility

Answer

Option C uses whole-facility metering to track energy changes, making it suitable when multiple measures interact or when individual isolation is impractical.

Question 2

What is the purpose of establishing an 'energy baseline' before implementing conservation measures?

Accepted Answer

To provide a reference for quantifying savings after implementation

Answer

A baseline documents pre-retrofit energy use so that post-implementation consumption can be compared to quantify actual savings achieved.

Question 3

A CEM is developing an energy master plan. Which element is MOST critical to include for long-term strategic success?

Accepted Answer

Aligned energy goals with organizational mission and capital planning cycles

Answer

An effective energy master plan integrates energy goals with organizational priorities and budget cycles to ensure sustained commitment and funding.

Question 4

Which strategy is MOST effective for managing electricity costs associated with time-of-use (TOU) rates?

Accepted Answer

Shifting non-critical loads to off-peak hours

Answer

Under TOU rates, electricity costs more during peak hours, so shifting flexible loads — like chilling, laundry, or charging — to off-peak periods directly reduces bills.

Question 5

An energy manager discovers that a chiller plant is running at 15% load most of the time. What strategy should be evaluated FIRST?

Accepted Answer

Stage chillers so fewer machines run at higher, more efficient loads

Answer

Chillers operate most efficiently near 80–90% of their design load; staging fewer units at higher loads eliminates the severe efficiency penalty of part-load operation.
