Final answer:
Occupancy sensors (automatic lights off) should be installed in areas where there is frequent movement of people, such as offices, restrooms, conference rooms, and classrooms.
Step-by-step explanation:
The correct answer is option Engineering. Occupancy sensors, also known as automatic lights off sensors, are typically installed in areas where there is frequent movement of people.
These sensors detect the presence or absence of people in a space and automatically turn the lights on or off accordingly. Some common areas where occupancy sensors are installed include:
- Offices: Occupancy sensors can be installed in individual offices or shared workspaces to ensure that lights are only on when someone is present.
- Restrooms: Installing occupancy sensors in restrooms can help save energy by turning off lights when the space is unoccupied.
- Conference Rooms: Conference rooms are often used intermittently, so occupancy sensors can be installed to automatically turn off lights when the room is unoccupied.
- Classrooms: Occupancy sensors in classrooms can help conserve energy by turning off lights when students and teachers are not present.
By installing occupancy sensors in these areas, energy consumption can be significantly reduced, leading to cost savings and a more sustainable environment.
Occupancy sensors should be installed in areas like hallways, bathrooms, and conference rooms, where people come and go without staying long. They must be positioned to detect movement effectively and to avoid false triggers.
This approach saves energy and provides convenience in smart homes, like the Hadley's HappyLife Home described in the context.
