Abstract
Recently, in the field of architecture, many kinds of daylighting devices have been studied to reduce energy consumption and environmental impact and to enhance indoor environmental quality. One of the devices is daylighting louver made of mirrors which can control direct light passively. However, it has some problems like glare caused by inaccurate light distribution, changing illuminance by solar movement, and shortage of interior illuminance under overcast conditions. To overcome these problems, the authors focused on transparent non-imaging optics with refraction and total reflection. This paper reports a new transparent daylighting louver whose effectiveness is verified by simulation and experiment.
