Daylighting in buildings, and especially in workplaces, is desired by most users and a proper use of daylight contributes to occupants' performance and well-being. Furthermore, the effects of light on people's health (effects beyond vision) have been the object of investigation during the last fifteen years. Although daylight is recognized to be the most energy-efficient means to deliver a proper light exposure, many buildings use artificial lighting extensively during the daytime in tropics. Daylighting implies the controlled use of natural light in buildings to achieve the desired visual, thermal, and psychological comforts. In a simulation study conducted by Pellegrino, Cammarano, Verso, and Corrado, (2017), the results highlighted the theoretical potential of daylight responsive control systems in reducing energy consumption, especially when rooms are designed to have at least sufficient (sDA > 55%) or, even better, favourably (sDA > 75%) daylighting conditions, the latter case resulted in energy saving using a manual on/off switch can be 42% on average.
