Mirror, Mirror on the - Roof? A brief history of active core sunlighting

Natural lighting is the most efficient form of renewable power because it is used immediately for its native properties without conversion to another medium and attendant losses. While the health benefits of natural light are well known, it can be difficult to provide in a densely built environment. According to the Illuminating Engineering Society, “Active core sunlighting is the process of intercepting sunlight at the envelope of a building with solar tracking optics, transporting it, and directing it within the building so as to provide appropriate illumination for a host of ambient, task and accent lighting applications” that might be remote from perimeter windows. As technological advances with mirrored systems and controls make the technique more practical it is useful to see examples of successes and failures over the years.

For those who qualify, 1.5 LU/HSWs are available.
