Newton North High School has the most efficient light bulbs and a sophisticated online system that allows workers to control energy use remotely. But turning off the hallway lights in the state’s most expensive high school poses a problem.
The three-year-old building cost more than $190 million to build. Darkening its hallways is more complicated than just flipping a switch, and the fix could cost the city another $20,000.
Far into most nights, the long corridors that stretch across the campus shine brightly and the glass encased entrance serves as a beacon in the neighborhood.
While the classrooms have occupancy sensors that can pick up motion and body heat and turn off when nobody is in the room for 30 minutes, the hallways aren’t equipped with the same technology. Full story for BostonGlobe.com subscribers.
