Light control systems including shades, blinds, and louvers improve occupant comfort and reduce cooling loads. Manually operated shades provide occupant control of light levels. Motorized systems provide automatic control and can respond to solar intensity. Exterior shading prevents solar heat gain before it enters the building. Interior shading provides light control but allows heat into the building. Building-integrated photovoltaic shading systems generate electricity while controlling light. Louver systems provide light admission while blocking direct sun. Angle adjustability allows control of light penetration. Translucent materials diffuse light improving quality. Daylight harvesting uses daylight sensors to reduce artificial lighting when sufficient daylight is available. Photosensors measure illumination levels. Dimming systems reduce artificial light output proportionally. Integration with occupancy sensors ensures lights are off when spaces are unoccupied. Energy savings from daylighting are significant in spaces with adequate window area. Occupant comfort improves with natural light connection to exterior. Views to outside improve occupant wellbeing. Glare control prevents discomfort from direct sun. Manual or automated glare control maintains visual comfort.
