Daylight management is an emerging term referring to strategies and technologies for controlling daylight penetration in interior spaces through windows, clerestories, skylights, tubular daylighting devices, and building core sunlighting systems to maximize daylight benefits.
The potential to reduce energy consumption in existing and commercial buildings is enormous. On average, 30% of the energy used in commercial buildings is wasted, according to the U.S. Environmental Protection Agency. Lighting has a large potential for energy savings for any U.S. building end use, with a significant fraction of that potential coming from lighting controls.
CLTC, in partnership with Southern California Edison, completed a project portfolio from 2014-2018 to assess controls, lighting, and daylighting technologies and their potential for commercial applications. The projects have elements of market assessment, EM&V, and selected demonstrations.
The project focus is on evaluating the following technologies:
LD+A— Core sunlighting is a practical, natural alternative for interior illumination deep within a building. Unlike other solar technologies, core sunlighting involves capturing sunlight at the building envelope, concentrating it, transporting it and regulating its release deep within the building at useful indoor lighting levels, typically only 1 percent of outdoor illumination. Significant electrical energy savings can be realized if the system incorporates automated electric lighting controls that substantially dim or completely turn off the electric lights.

The IES's Recommended Practice for Daylighting Buildings (RP-5-13) recently garnered an award at Lightfair International 2014. The Recommended Practice guide was selected for top honors in the "Research, Publications, Software and Measuring Devices" category.
The Honda Smart Home US is a model zero net energy (ZNE) home located in the UC Davis West Village. Honda collaborated with UC Davis, CLTC and WCEC to build this forward-thinking example of residential sustainability. The home includes daylighting, advanced lighting controls, and high-efficacy, circadian-friendly LED lighting.
Keynote Speaker:
Dr. Lorne Whitehead
Professor of Applied Physics
University of British Columbia
Dr. Lorne Whitehead of the University of British Columbia (UBC) spoke on advances in daylighting technologies for buildings. Dr. Whitehead introduced the SunCentral Core Sunlighting System, a device that harnesses daylight to illuminate the windowless cores of buildings.
