COVID-19 Update:

To protect the health of our staff and our customers, Efficiency Vermont offices are closed to the public. In the meantime, our customer support team is available to help you remotely. Contact us at (888) 921-5990 or

We have cautiously begun scheduling project related site visits when required. You can find more information on our safety protocols here.

Where to Mount Sensors

Light switches with embedded sensors can replace old light switches in small rooms and offices. Fixture-mounted sensors are recommended for medium-sized spaces (such as classrooms), high-ceilinged areas, and exterior areas. Remote-mounted wall and ceiling sensors are connected to a master control and work best in large, open spaces. And some sensors are wireless, which can help avoid the cost of rewiring existing lights. Contact us for advice on the right solution for you.

  • Guarantee savings by using lights only when needed
  • Automate energy usage with the right sensor for your business or home
  • Choose a sensor mounting location based on your space’s size and use

Sensor Technologies

There’s a sensor for every business and home application. Passive infrared (PIR) technology sensors are suited to rooms with no partitions, though inadvertent shut-offs can occur if motions are subtle (like typing). Ultrasonic and acoustic technologies work better when there’s no direct line of sight between sensor and occupant. Pairing two technologies in one sensor can work well—nearly eliminating false shut-offs.

  • Lower energy bills with occupancy and daylight sensors
  • Choose the right sensor for your space: PIR, ultrasonic, acoustic, or dual
  • Avoid false shut-offs with dual technology sensors

Advanced Commercial Controls

Save 50-75% on energy costs with advanced controls customized for your business. Advanced lighting controls are networked together and blend multiple strategies such as time-scheduling technology, occupancy and daylight sensors, off-site remote management, personal override, and web-based tracking. Integrated lighting controls refer to LED fixtures that come pre-equipped with two built-in sensors (one daylight, one occupancy). Contact us for an assessment.

  • Track energy savings in real time to see what strategies work best
  • Adjust your lighting remotely from a web-based interface

What Is Daylighting?

Daylighting is “harvesting” daylight (or natural light) from strategically placed skylights and windows to conserve electricity. Daylighting makes retail spaces more appealing and can spur higher visit and purchase rates. It can also boost worker productivity and morale, or student performance in schools, while lowering lighting and even cooling costs. Buildings that use daylighting often enjoy better lease rates, lower tenant turnover, and higher resale values.

  • Please your customers with attractive, well-lit spaces
  • Boost worker productivity and morale with natural lighting
  • Save on energy costs thanks to lower electric and cooling bills
