Daylight redirecting films DRF were produced in a roll-to-roll format that consisted of acrylic micro-prismatic elements on a clear polyester polyethylene terephthalate PET substrate and coated with a pressure sensitive adhesive PSA on the backside. The microstructures are designed to maximize reflection of incident sunlight towards the ceiling to allow the ceiling surfaces to redistribute the light more uniformly in the space. The films were installed in six different Department of Defense DoD buildings scattered across three different climate zones. The sites were selected based on user profile, building location, access, window design and structure as well as availability of similar, if not identical, space that could be designated as control space in order to perform a side-by-side comparison.
