| Summary: | Artificial lighting is one of the major electricity consumption in commercial buildings and consumed about 17%
of the total electrical energy. Therefore, there is a great potential to reduce energy consumption by implementing
intelligent lighting control systems, such as integration of sensor technologies (occupancy and light sensors),
advanced architectures (wireless- and network-based architectures), and intelligent control techniques (artificial
intelligent and optimization). Moreover, an intelligent control system is capable of enhancing the visual comfort
of occupants, and reduce electricity consumption and greenhouse gas emission. The lighting control system can
be broadly categorized into three main techniques: controller-, optimization-based control, and hybrid. This
paper presents recent and significant state-of-the-art interior lighting system control techniques in commercial
buildings. The review focuses on several key research, including sensing technologies, objective functions and
constraints, techniques, tools, and energy performances. A survey trend analysis is presented graphically and the
findings are discussed extensively. Based on the comprehensive review of lighting control techniques, it is found
that the optimization-based control technique is widely used by 51% compared to other techniques as it has
superior performance to achieve higher energy savings while satisfying visual comfort of occupants, and at the
same time the technique solves multi-objective problems effectively. Moreover, future directions have been
drawn based on the highlighted gaps toward intelligent and sustainable buildings. |
