Daylight Factor Analysis with Slat Angle Control for Glare Reduction in a Three Storied Office Building

摘要

Estimation of daylight Factor is important to get sufficient, daylight into a room. Window blinds have a large effect on daylight factor. Window blinds slat angle control not only estimates direct solar penetration, but also makes the workplane illuminance within agreeable range. Key findings from the study are window blinds help to control glare, daylighting and overheating. Window blinds control by occupants is an attempt to mitigate building energy use. Slat angle control must be designed effectively to get a good response from occupants. We find that, a slat angle of 15° provides uniform illuminance for East, and West facing rooms in Bhubaneswar, Odisha, India.
