CEM Methods and Strategies 4

Question 1

Which financing mechanism allows an organization to fund energy upgrades with no upfront capital by using guaranteed future energy savings?

Accepted Answer

Energy savings performance contract (ESPC)

Answer

An ESPC uses an energy service company (ESCO) that guarantees savings sufficient to cover project costs, eliminating the need for upfront capital.

Question 2

In the Plan-Do-Check-Act (PDCA) cycle applied to energy management, what occurs during the 'Check' phase?

Accepted Answer

Performance is monitored and measured against objectives

Answer

The Check phase involves comparing actual energy performance against targets using metered data and KPIs to determine whether actions achieved expected results.

Question 3

A manufacturing plant uses a steam distribution system. Which strategy offers the GREATEST energy savings potential with moderate investment?

Accepted Answer

Auditing and replacing failed steam traps

Answer

Failed steam traps continuously vent live steam, and a systematic trap survey and replacement program typically yields 10–20% steam system energy savings.

Question 4

What does 'load disaggregation' mean in the context of advanced energy management strategies?

Accepted Answer

Identifying energy consumption by individual end-use from whole-building meter data

Answer

Load disaggregation uses algorithms to extract appliance- or system-level consumption signatures from aggregate metering data without sub-metering each device.

Question 5

Which factor MOST significantly affects the decision to pursue an on-site combined heat and power (CHP) system?

Accepted Answer

High simultaneous demand for both electricity and thermal energy

Answer

CHP is economically attractive when a facility has a consistent, year-round need for both power and heat (or cooling via absorption chiller), allowing most of the fuel energy to be utilized.
