CEM Event Operations Management 3

Question 1

An energy manager is designing a retrocommissioning plan for an event venue. Which system should be prioritized first for highest energy impact?

Accepted Answer

Central air handling units serving the main event spaces

Answer

Central air handling units serving large event spaces typically represent the largest single energy end use in event venues, making them the highest-priority retrocommissioning target.

Question 2

What is the primary purpose of a load profile analysis conducted before an event?

Accepted Answer

To identify demand peaks that could trigger ratchet charges and develop strategies to flatten them

Answer

Load profile analysis reveals when and where demand peaks occur, enabling proactive load shifting and shedding strategies to avoid costly ratchet charges.

Question 3

During setup for a large exposition, temporary power distribution equipment (spider boxes, cable runs) is installed. What energy management concern is highest priority?

Accepted Answer

Verifying that temporary equipment does not cause harmonic distortion that degrades power quality and increases losses

Answer

Heavy non-linear loads from exhibitor equipment can cause significant harmonic distortion, increasing I²R losses, overheating transformers, and reducing overall system efficiency.

Question 4

A venue's boiler system serving event space heating is operating with a flue gas temperature of 450°F. What does this indicate?

Accepted Answer

Excessive stack heat loss is occurring, suggesting the need for economizer or combustion tuning

Answer

A 450°F flue gas temperature is well above the optimal range, indicating significant heat is being wasted up the stack and that combustion tuning or an economizer could recover substantial energy.

Question 5

What is the most effective way to manage plug load energy waste from exhibitor booths during non-show hours?

Accepted Answer

Install smart power strips with occupancy-sensing auto-shutoff at each booth circuit

Answer

Smart power strips with occupancy-based auto-shutoff enforce energy management passively without relying on exhibitor behavior change.
