Metal-free nanotechnology in 3M™ Window Film Prestige Exterior Series rejects up to 97 per cent of the sun’s heat-producing infrared light and up to 99 per cent of UV rays, helping the Rock N’ Roll Hall of Fame reduce energy costs by 8 to 12 per cent annually.
Use silver metallised and weatherable polymeric film with a solar-weighted total hemispherical reflectance of 94% to direct light. The result: Brighter LED lamps in Africa.
Using aluminium composite for the conductor core of a power line means you can carry twice the electrical power at half the weight—without disrupting existing infrastructure.
Micro-structured prisms optically direct as much as 80 per cent of exterior natural light in and up, helping a first-of-its-kind Walgreens Net Zero chemist produce more energy than it consumes.
