Event Operations Management Flashcards

During a large convention, the facility's chiller plant is operating at 95% capacity. What is the most effective immediate action for an energy manager?

Answer: Shed non-critical loads such as unoccupied meeting room HVAC zones

Shedding non-critical loads in unoccupied zones immediately reduces demand on an overtaxed chiller plant without capital expenditure.

A convention center wants to measure the energy impact of a 3-day trade show. Which baseline methodology is most appropriate?

Answer: Use a weather-normalized baseline derived from regression analysis against HDD/CDD

Weather-normalized regression baselines account for outdoor conditions, making comparisons between different event periods more accurate and defensible.

Which metric best quantifies the energy intensity of a large event for benchmarking purposes?

Answer: kWh per attendee-day

kWh per attendee-day normalizes energy use for event size and duration, enabling meaningful comparisons across different events.

An event manager notices that exhibit hall lighting accounts for 40% of event energy costs. What control strategy would have the greatest impact?

Answer: Implement zone-by-zone dimming tied to the exhibit hall occupancy schedule

Zone-by-zone dimming aligned with the occupancy schedule targets energy precisely where and when it is not needed, avoiding blanket reductions that may compromise safety or exhibitor needs.

A stadium hosting a nighttime event requires full field lighting for 4 hours. The utility offers a time-of-use (TOU) rate with an on-peak period ending at 9 PM. How should the energy manager advise scheduling pre-event lighting warm-up?

Answer: Begin warm-up before 9 PM only if the lamps require it for color rendering stability, accepting some on-peak cost

Metal halide and some HID lamps require warm-up time for color stability; the energy manager must balance TOU savings against operational requirements and may need to start slightly before 9 PM.

Which demand response strategy is most compatible with maintaining attendee comfort during a packed arena event?

Answer: Pre-cooling the arena 2 hours before the event to allow demand reduction during the event itself

Pre-cooling (thermal mass pre-conditioning) stores cooling energy before peak periods, allowing reduced mechanical operation during the event without sacrificing comfort.

A facility's energy management system shows a spike in natural gas consumption coinciding with each event's catering setup. What is the most likely cause?

Answer: Gas-fired make-up air units bringing in large volumes of unconditioned outdoor air through kitchen exhaust replacement

Commercial kitchens require large make-up air volumes to replace exhaust air; gas-fired make-up air units condition this outdoor air and can cause significant gas consumption spikes during catering operations.
