    Micro-structured prisms optically direct as much as 80 percent of exterior natural light in and up, helping a first-of-its-kind Net Zero Walgreens drugstore produce more energy than it consumes.

    • Daylight Redirecting Film

      Micro-structured prisms optically direct as much as 80 percent of the exterior natural light in and up, helping a first-of-its-kind Net Zero Walgreens drugstore produce more energy than it consumes. 3M™ Daylight Redirecting Window Film is part of the Evanston, Illinois store’s net-zero design, installed on 4,000 square feet of west-facing glass to help light the room as deep as 40 feet from the windows. With this technology, the energy of natural daylight can be “harnessed”—extending it into a building's interior, and translating to as much as a 52 percent reduction in lighting energy costs.

      See how we’re extending daylight and lowering energy costs.
