Luminance-Map Based Glare Sensor for use with Dynamic Window and Skylight Systems

Tech ID: 25929 / UC Case 2016-713-0

Abstract

Researchers at the University of California, Davis have developed a unique glare sensor, based on luminance maps, which can be used with dynamic window and skylight systems.

Full Description

Automated operation of dynamic window and skylight systems often requires knowledge of the sun’s position in relation to the said window or skylight. Traditional approaches to determine this relative position rely on geospatial coordinates of the window location, window or skylight orientation as well as inputting various external conditions. Traditional approaches however cannot account for cases where indirect/reflected, rather than direct, solar radiation occurs on the window or skylight.

Researchers at the University of California, Davis have developed a unique glare sensor, based on luminance maps generated through digital imaging, which can be used with dynamic window and skylight systems. This system requires no input and can account for both direct and indirect solar radiation, as it senses, rather than computes solar position.

Applications

  • Automated dynamic window and skylight systems

Features/Benefits

  • Eliminates need to input geospatial coordinates
  • Automatically determines the incoming direction of glare from direct and indirect/reflected sunlight
