    Performance analysis of smart lighting control system for sustainable campus operation
    Global warming is a growing issue today due to the concerns of carbon emissions to the environment. Meanwhile, learning institutions such as university could play a significant role in promoting energy conservation and sustainable campus operations. The objective of this paper is to highlight the performance of smart lighting control system for restrooms where the project has been carried out at the Faculty of Electronic Engineering Technology, Universiti Malaysia Perlis. The methodology processes include the initial study and field measurement of the energy consumption for lighting system during pre-retrofit condition, design, and development of the lighting control system and lastly analysis of the designed system in post-retrofit condition after installation. On the overall, 58 motion sensors have been installed at 30 restrooms where the result shows that in average 77.5% of reduction in energy consumption per day for each restroom. This situation has given tremendous benefits to the university operation where the university could save 9377 kWh per year and reduced RM 3423 from electricity bill per annum. In addition, this project also contributes to the environmental sustainability where the amount of electrical energy that has been successfully reduced is equivalent to 6508 kg of CO2 avoidance to the environment.

    Smart lighting system control strategies for commercial buildings: A review
    Rapid global economic growth and growing population have tremendously led to the increasing demand for energy needs in commercial and residential buildings. The main energy resources for electrical energy generation in Malaysia are fossil fuels. The increase in electricity demands causes simultaneous proportional growth in fossil fuel consumption, thereby leads to higher greenhouse gas emissions. Buildings have emerged as the most voracious electrical energy consumer which contributes over one-third of global energy consumption. Furthermore, lightings and air-conditioning systems have the most significant impacts on the total electricity usage of buildings in Malaysia. Thus, energy efficiency efforts targeting both loads will significantly reduce total energy consumption in the buildings. This paper aimed at reviewing energy efficiency efforts at the commercial buildings and comparison between simple strategy and SMART Building by using Building Energy Management System (BEMS). Many aspects of energy efficiency efforts will be considered such as energy consumption, occupant comfort, and system cost. Furthermore, suggestions for improving energy efficiency in the commercial building using the best strategy to reduce energy consumption by using a lighting control system will be discussed.
