Classrooms

Designing an energy-efficient classroom with occupancy sensors involves careful planning and strategic placement of sensors:

• Wall Occupancy/Vacancy Sensors: Install these sensors near the main entrance of the classroom. These sensors can detect when someone enters or leaves the room, and can automatically turn the lights on or off accordingly. They can also be manually controlled to turn all lights on or off.
• Ceiling Occupancy Sensors: These sensors should be installed in the center of the classroom, ensuring they have a clear view of the entire room to cover key areas such as the teacher’s desk, student desks, and any separate learning areas. They can detect any movement in the room, including minor movements such as students writing at their desks. When no movement is detected for a set period, the lights will automatically turn off.
• Additional Sensors for Specific Areas: If the classroom has specific areas such as a reading corner or a lab area, additional sensors may be needed. These sensors can control the lighting in these specific areas based on occupancy, ensuring that lights are not left on unnecessarily.
• Sensor Placement Considerations: Avoid placing sensors near air vents or other sources of movement that could trigger the sensor falsely. Also, ensure the sensors’ view is not obstructed by tall furniture or fixtures.
• Consideration of Natural Light: If the classroom has windows, the sensors should be programmed to consider the natural light coming into the room. This can help to further reduce energy consumption by utilizing natural light whenever possible.
• Integration with Manual Control: All occupancy/vacancy sensors should be integrated with manual controls. This allows teachers to manually turn off the lights during activities like video presentations, even if the room is occupied.
