The quest for energy efficiency should not stop after a building is certified under the Leadership in Energy and Environmental Design (LEED) program. Technologies capable of reducing energy costs continue to evolve and are in a state of flux. Therefore, there is always potential for improvement upon the technology used in a LEED-certified building. Perhaps no area of building technology has improved so rapidly as the lighting industry.
The introduction of light-emitting diode (LED) fixtures has changed the established view of light sources. Best known for their ability to provide quality lighting with lowered energy costs, LEDs, in reality, represent a paradigm shift in the capabilities of a light fixture.
San Francisco’s LightHouse for the Blind and Visually Impaired is a 115-year-old social services organization serving people who are blind or have low vision. In designing the organization’s new headquarters, the architects at Mark Cavagnero Associates had the opportunity to reimagine their usual design process and rethink how to create beautiful spaces focusing on all senses.
Human sight evolved to optimize vision under diffuse sky radiation, and this remains the best illumination conditions for most of our activities. Luminous ceilings are an attempt to reproduce the qualities of such overhead lighting in an indoor environment.
Design/construction professionals hope their project designs proceed without missteps or complications. Of course, that rarely happens. The lighting product specification and bidding process is complex, as it involves many interested parties, each with its own stake in which products are ultimately installed in the project.
