3M™ Daylight Redirecting Window Film is part of the Evanston, Illinois store’s net-zero design, installed on 370 square metres of west-facing glass to help light the room as deep as 12 metres 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% reduction in lighting energy costs.
See how we’re extending daylight and lowering energy costs.
