Daylighting Systems Inc. (DSI) is the Nations leader in the design, manufacturing and installation of full spectrum daylighting products. We are the only daylighting company in America which offers active daylighting, passive daylighting, hybrid lighting systems, darkening screen devices, lighting controls and design/consultation services. We continue to lead the industry in innovation and implementation of new technologies and are currently merging our daylighting systems with highly efficient LED lighting technologies to create the ultimate cost effective natural lighting system. We revolutionized the daylighting industry in 2000 when we introduced the worlds first under the dome active unit and again in 2002 when we unveiled the first integrated hybrid lighting systems. DSI Light Harvesting Fixtures differ greatly from traditional skylights, incorporating multiple components that diffuse daylight throughout the work area, prevent solar heat gain, and create calibrated, controllable, and aesthetically pleasing light. We work with architects and builders to ensure a seamless and successful integration with existing building systems or to upgrade with new green ideas. When prioritizing renewable energy and energy conservation initiatives, daylighting reduces the payback period of alternate rooftop renewable energy technologies when used in conjunction with them.
