An event venue's electrical demand charge is based on the highest 15-minute average kW recorded during the billing month. A rock concert is scheduled for the first day of the month. What is the energy management implication?
Answer: The demand peak from the concert will set the ratchet for the entire month, making it essential to minimize peak demand during the concert
Because the billing demand is set by the single highest 15-minute interval in the month, a peak during an early-month concert establishes the demand charge for all subsequent weeks regardless of lower usage.
What is the role of a building automation system (BAS) sequence of operations during event transitions, such as moving from setup to full occupancy?
Answer: The BAS executes pre-programmed setpoint and mode changes to ramp HVAC systems ahead of occupancy changes, avoiding reactive energy spikes
Pre-programmed BAS sequences allow HVAC systems to transition smoothly and efficiently between event phases, avoiding the energy penalty of reactive, manual system adjustments.
An outdoor festival is using diesel generators for temporary power. Which operating practice most significantly reduces fuel consumption and emissions?
Answer: Right-sizing generator sets so each operates between 70–80% of rated capacity
Diesel generators are most fuel-efficient between 70–80% of rated load; operating below 40% causes wet stacking and high specific fuel consumption.
A facility energy manager notices that CO2 levels in a ballroom rise sharply 30 minutes into events, then stabilize. What does this pattern most likely indicate?
Answer: The demand-controlled ventilation (DCV) system has a control lag and needs its response time tuned
A sharp rise followed by stabilization typically indicates a DCV control lag — the system detects occupancy-driven CO2 rise but takes time to ramp up outdoor air delivery, after which levels stabilize.
Which strategy best addresses the 'elevator effect' — the energy impact of hundreds of attendees using elevators simultaneously between event sessions?
Answer: Install regenerative drives on all elevators to recover braking energy
Regenerative drives capture kinetic and potential energy during braking and deceleration, returning it to the building electrical system and reducing net elevator energy consumption.
A sports arena uses retractable seating that requires large electric motors. What energy management opportunity does this equipment present?
Answer: Using regenerative braking on retraction motors to recover energy when seating closes
Retractable seating loads have significant gravitational potential energy when extended; regenerative motor controls can recover this energy during retraction rather than dissipating it as heat.
Under ASHRAE Standard 90.1, what is the primary energy-related requirement for lighting in large event spaces with multiple occupancy modes?
Answer: Lighting control systems must provide multi-level switching or dimming with at least two intermediate levels between off and full power
ASHRAE 90.1 requires multi-level lighting controls in large spaces so that energy is proportional to actual needs, with at least two intermediate levels providing flexibility for different event configurations.
