Easy-to-install Wireless Sensors------ Save nearly two months of electric bills for your building each year

Portland, OR -- Simply failing to “flick the switch” and turn off the lights in an unoccupied room is one of the largest wastes of precious energy resources. For a large commercial building, this frequent oversight can equal up to thousands of dollars of “energy waste” each year.

Traditional occupancy sensors are a proven solution for shutting off unused lights, and have been shown to save up to 80 percent of the energy used for commercial interior lighting. But upfront costs associated with retrofit installations convince many to stick with their old style switches.

Now, a local Oregon division of Leviton headquartered in Tualatin, is offering an ingenious and flexible solution that will turn off the lights and turn down installation expenses at the same time.

Leviton Lighting Management Systems division has introduced an exclusive line of wireless, self-powered occupancy sensors and wall-switch receivers that are easily installed in virtually any room or building.

Their wireless functionality requires no additional wiring. Instead, the occupancy sensors use integrated solar cells to converts ambient room light to energy. And a remote switch draws on kinetic energy for recharging each time the buttons are pushed. The components integrate technologies developed by and licensed from EnOcean (, a worldwide leader in wireless control technology.

“These unique wireless, self-energizing components provide a reliable and trouble-free lighting-control solution,” said Bob Freshman, Marketing Manager, Leviton. “Installation is quick and easy, with no drilling, no wires to run and no conduit to pull. Just replace the existing wall switch with the new receiver switch, then attach the occupancy sensor, and the install is complete.”

In fact, Leviton research shows that labor and material costs can be reduced by as much as 50 percent when compared to conventional hardwire systems, while installation time can be trimmed by as much as 75 percent.

The system is cost effective for lighting management projects for both new construction, and especially for retrofits to existing spaces. “There’s no damage to walls or ceilings, which means it’s perfect for historical or older buildings where retrofitting with wires can be especially costly or even impossible to do,” said Bob.

Even more significant are the potential energy cost savings. Industry estimates show that lighting accounts for nearly 50 percent of electricity use in commercial buildings. “It’s clear that an 80 percent savings in lighting costs could equal big bucks for building owners and tenants,” said Bob.

The wireless occupancy sensors and wall-switch receivers are part of the extensive Leviton LMS line of integrated energy management and architectural lighting control products.

The company is proud to be part of Oregon’s recognized leadership in green construction, manufacturing and energy solutions. “Effective energy management is fundamental to conservation,” said Richie Westfall, Leviton’s Vice President and General Manager. “And conservation is the most efficient means for reducing dependence on carbon-based fuels and lowering greenhouse gas emissions.”
