COMPARISON STUDY ON EFFECT OF SLAT SHAPE AND OPTICAL PROPERTY OF GRADATION BLIND ON REDUCTION OF ELECTRIC CONSUMPTION FOR AMBIENT LIGHTING

Abstract

In order to identify the effect of the slat shape and optical property of Gladiation blind on reduction of electricity consumption for ambient lighting, a numerical simulation and measurements were carried out. The result showed the effect of slat shape and optical property of Gradation blind on the reduction of the electricity consumption for ambient lighting. It was also shown that the reduction of the electricity consumption for ambient lighting by gradiation blind was greater than that by a conventional blind with an automated dimmable lighting system.
