CEM Methods and Strategies 2

Question 1

Which energy management strategy prioritizes actions based on their potential return on investment and ease of implementation?

Accepted Answer

Opportunity matrix analysis

Answer

An opportunity matrix plots energy projects by cost-effectiveness versus implementation difficulty, helping managers prioritize high-value, low-barrier actions first.

Question 2

A CEM implements an energy information system (EIS). What is the PRIMARY purpose of this system?

Accepted Answer

Provide real-time monitoring and reporting of energy use

Answer

An EIS collects, stores, and displays real-time energy consumption data, enabling managers to detect anomalies and measure savings.

Question 3

What does the term 'energy intensity' measure in the context of energy management strategies?

Accepted Answer

Energy consumed per unit of output or floor area

Answer

Energy intensity normalizes consumption against production output or building area, allowing meaningful performance comparisons across different periods or facilities.

Question 4

A plant manager wants to reduce compressed air system energy use by 20%. Which strategy should be investigated FIRST?

Accepted Answer

Conduct a leak detection and repair survey

Answer

Compressed air leaks typically waste 20–30% of output, making leak detection the highest-priority, lowest-cost first step.

Question 5

Which of the following BEST describes the 'no-cost/low-cost' tier in a phased energy management strategy?

Accepted Answer

Operational and behavioral changes requiring minimal expenditure

Answer

No-cost/low-cost measures — such as adjusting setpoints, fixing scheduling errors, and staff awareness programs — are implemented first to generate quick savings with negligible capital outlay.
