The U.S. Department of Energy (DOE) is proposing to provide federal funding to Glint Photonics, Inc. (Glint) to develop the Glint Stationary Concentrator Daylighting System (SCDS) into a full-scale integrated prototype and evaluate its performance in a demo installation. The SCDS consists of sunlight collecting panels and optics that redirect sunlight into the interior of a building. Project work would take place at the Glint research facility in Burlingame, California and a demonstration site that has yet to be determined.

Project activities include the design, development, fabrication, and testing (indoor and outdoor) of the SCDS. Laboratory work at Glint’s facility would involve the use and handling of various hazardous materials such as solvents and adhesives in assembling the panels for the SCDS. All such handling would occur in-lab with no risk to the public. All project workers would be subject to the standard risks inherent in laboratory research using common chemicals and equipment so all project workers receive relevant safety training prior to beginning laboratory work. Glint has multiple layers of protection for workers, including ventilation, containment, safety equipment, and procedures. Glint has procedures in place to safely store, transport, and dispose of hazardous solid and liquid wastes in accordance with applicable federal, state, and local requirements. Anticipated air emissions under the proposed project would be within air quality requirements/limits and managed in accordance with federal, state, local requirements or facility specific guidelines. Prototype daylighting systems would be installed on the rooftop of Glint’s facility for a period of at least six months.
