The concept of daylight harvesting is simple. Digital photo sensors detect daylight levels and automatically adjust the output level of electric lighting to create a balance. The goal is energy savings.
Studies indicate that electric lighting energy use can be reduced as much as 84% using daylight-harvesting products. Among them: Sunoptics Prismatic Skylights.
Complications associated with commissioning have, historically, kept the enthusiasm for daylighting at a rather modest level. But now, companies like LC&D offer feature-rich, integrated lighting controls that maximize the benefits of daylighting.
