Abstract

Automated blinds need to be controlled to maximize benefits of daylight to enhance occupant comfort and to reduce energy consumption. However, previous control methods focused on minimizing the negative impacts of daylight, but failed to maximize the positive impacts of daylight and solar heat gain. The objective of this study is to develop an optimized control algorithm for automated venetian blind which would reduce the negative effects of incoming daylight on visual comfort of occupants, and to minimize psychological anxieties caused by frequent motions of the blind, by maximizing the positive effects of incoming daylight and solar irradiation, by opening/closing of the blind. Through implementation of the proposed methods and algorithms, the direct glare on work-planes could be prevented at all time, and also incoming daylight and solar irradiation could be increased.
