Core Sunlighting Technology: Offering a new approach to green building

Recent technological advances have made it practical to deliver concentrated sunlight deep inside buildings. This new approach to energy-efficient lighting means almost all areas of a building can be illuminated whenever the sun shines without requiring any increase in floor-to-floor height or large expanses of glazing. As a result, core sunlighting has the potential to significantly influence how the building industry optimizes green building designs.

By its very nature, indoor air quality (IAQ) is fragile and fickle—easily disturbed by the most minute of changes to the built environment, whether during construction or occupancy. In fact, even the seemingly innocuous introduction of new products and materials, such as wall and ceiling assemblies, can damage indoor air quality and, as a result, create an unhealthy space for both contractors and occupants.
