This paper explains High Dynamic Range Imaging (HDRI) technology for the control and optimization of visual comfort, thermal comfort and energy consumption in daylight-artificial light integrated scheme. The objective of this work is to incorporate image sensors, Wi-Fi and ZigBee to make an economical solution for reducing energy consumption while improving visual comfort levels. The camera based fuzzy model presented determines the position of blinds ensuring visual and thermal comfort by reducing glare and maintaining uniformity. MATLAB - SIMULINK technical computing and visualizing environment is used to obtain the complete system including making HDR images, calibration of camera, formulation of control algorithm for artificial light and window blind control as well as to analyse the quality aspects of daylight-artificial light integrated scheme.
