A light shelf is a horizontal or near horizontal baffle fitted part way up a window to control and redistribute incoming sunlight and daylight. This paper describes a computer program to analyse light shelves and other daylighting systems. The program agreed well with measurements made in experimental rooms at the Building Research Establishment. Experimental measurements had revealed that an internal light shelf could improve the uniformity of daylight in a room and provide some solar shading… 

A Review of Light Shelf Designs for Daylit Environments

A review of the research realized in the last three decades concerning light shelves together with their associated implications in a building’s daylight performance as well as in its energy balance in a few cases is reviewed.

Light trespass protection in a glazed office building:how the shading system works?

Light trespass has been regarded as one major type of light pollution in urban areas. This study presents an investigation of the impact of six various shading devices on the light trespass risk in a

Lighting energy savings due to the use of a sun tracking mirrored lightself in office buildings

The proper use of daylight lays a solid cornerstone to the framework of energy saving techniques in non residential buildings, satisfying the occupants’ physiological and psychological needs. It is

Optimization of office building window lighting in Ahvaz

Investigation and explanation of an optimum dynamic lighting system to equip office building windows in order to deepen, balance and control the received light found that an optical niche with optimized dimensions and angle leads to deeper light penetration into the room.
