Question

Occupancy sensors MUST automatically turn off lights within _____ minutes of occupants leaving EXCEPT in warehouses

Answer 1

Occupancy sensors must typically turn off lights within 30 minutes of a space being vacated, but warehouses may have different requirements.

Step-by-step explanation:

The question pertains to the regulation regarding how quickly occupancy sensors must automatically turn off lights when a space is unoccupied, with an exception noted for warehouses.

For most spaces, occupancy sensors are required to turn off lights within a specific timeframe to conserve energy. In the U.S., under the prevailing energy codes such as the International Energy Conservation Code (IECC) and ASHRAE 90.1 standards, occupancy sensors must typically turn off lights within 30 minutes of the space being vacated. Warehouses, due to their size and different use patterns, may have different requirements or extended time delays before the lights are turned off automatically.
