Introduction
Schools and daycares have unique requirements for PIR sensors: energy efficiency, safety, and privacy. This guide covers the best options for classrooms, hallways, restrooms, and common areas.
Key Requirements for Educational Facilities
1. Energy Savings
Schools operate during specific hours but spaces may be empty during classes. Occupancy sensors can save 20-30% on lighting.
2. Seated Occupant Detection
Classrooms require sensors that detect seated students (not just motion).
3. Privacy Preservation
Restrooms and changing areas need sensors that detect occupancy without cameras.
4. Safety
Emergency lighting, lockdown detection, and evacuation monitoring.
5. Durability
Sensors in schools must withstand daily use and occasional abuse.

Energy Savings Potential for Schools
According to DOE studies, occupancy-based control in schools can save:
- 20-30% on lighting energy
- 10-15% on HVAC energy
- Payback period: 2-3 years
Installation Tips for Schools
- Use ceiling-mounted sensors for classrooms and hallways
- Set hold times appropriately (5-10 minutes for classrooms, 2-5 minutes for hallways)
- Enable daylight harvesting near windows
- Use vacancy mode (manual-on) for restrooms to save energy
- Test sensors during occupied and unoccupied periods
Compliance with School Energy Codes
- California Title 24 requires occupancy sensors in all classrooms
- ASHRAE 90.1 requires occupancy sensors in most school spaces
- IECC (International Energy Conservation Code) similar requirements
Conclusion
For classrooms, the Panasonic PaPIRs+ offers excellent seated occupant detection. For hallways, the Leviton OSSMT provides wide coverage. For restrooms, the Lutron Maestro is easy to install and privacy-preserving.
