In a typical Lubbock school building, lighting and climate control account for the lion’s share of monthly utility costs. One of the most frustrating sights for any facility manager is a row of classrooms with lights blazing and air conditioning humming long after the students and teachers have gone home for the day.
At SPS Electric, we specialize in integrating “Smart Controls” into existing school infrastructures. By utilizing motion sensors and programmable timers, schools can transition from manual management to an automated electrical system that only consumes energy when it is actually needed.
1. The Power of Occupancy and Vacancy Sensors
The simplest way to eliminate waste is to ensure that lights are only on when a room is occupied.
-
Occupancy Sensors: These “Auto-On/Auto-Off” sensors detect motion the moment someone enters a room and switch the lights off after a set period of stillness.
-
Vacancy Sensors: These are “Manual-On/Auto-Off” units. A teacher must physically turn the light on, but the sensor ensures they aren’t accidentally left on overnight. This is often the preferred choice for classrooms with large windows, as it encourages the use of natural West Texas sunlight.
2. Ultrasonic vs. Passive Infrared (PIR)
Not all sensors are created equal. Choosing the right technology is key to avoiding “false offs”—when the lights go out while students are still taking a quiet exam.
-
PIR Sensors: These “see” heat and motion. They are excellent for small offices or hallways but require a direct line of sight.
-
Ultrasonic Sensors: These use sound waves to detect movement, even around corners or over tall partitions like library bookshelves.
-
Dual-Technology: At SPS Electric, we often recommend dual-tech sensors for classrooms. They require both heat and sound signatures to keep the lights on, providing the highest level of reliability.
3. Programmable Timers for “Always-On” Areas
Some areas of a school, like hallways, stairwells, and exterior entryways, need to remain lit during specific hours regardless of motion.
-
Digital Astral Timers: These smart timers automatically adjust to the changing sunrise and sunset times in Lubbock. You’ll never have to worry about resetting timers for Daylight Savings or shorter winter days.
-
Holiday Scheduling: Advanced timers can be programmed with the entire school calendar, automatically shifting the building into “Deep Sleep” mode during Thanksgiving, Winter Break, and Summer Vacation.
4. Integration with HVAC Systems
Smart Electrical controls don’t have to stop at the lights. Many modern sensors can be integrated with the school’s Building Automation System (BAS) to control the thermostat.
-
Temperature Setbacks: When a sensor detects that a classroom has been empty for over 30 minutes, it can signal the HVAC system to adjust the temperature by a few degrees. Over a large campus, these small adjustments lead to massive cumulative savings on cooling costs.

The “set it and forget it” nature of smart controls removes the burden of energy conservation from the teachers and janitorial staff. It ensures that the district’s budget is being spent on student resources, not on lighting empty hallways.
At SPS Electric, we provide end-to-end service—from auditing your current usage to installing and programming your new smart devices. We can even help you identify local utility rebates that can help offset the cost of the upgrade.
