Lighting controls are typically installed in buildings in order to

Lighting controls are devices or systems that can regulate the amount and quality of light in a space according to various factors, such as user preferences, natural light availability, occupancy, and time of day. By doing so, lighting controls can improve occupant comfort and save energy throughout the building. Lighting controls can enhance the visual comfort, well-being, and productivity of the occupants by providing them with appropriate and adjustable light levels for different tasks and moods. Lighting controls can also reduce the energy consumption and environmental impact of the lighting system by avoiding unnecessary or excessive lighting, which can waste electricity, generate heat, and contribute to greenhouse gas emissions.Lighting controls are an essential component of green building design and certification, such as LEED v4, which has adopted ASHRAE Standard 90.1-2010 as the baseline for energy performance and lighting requirements. LEED v4 also recognizes and rewards various lighting control strategies, such as automatic shutoff, light-level reduction, daylight harvesting, exterior lighting control, and plug-load control. References: [LEED Link: Minimum Energy Performance], section “LEED v4 BD+C: Minimum Energy Performance”; [LEED Link: Lighting Controls], section “LEED v4 BD+C: Lighting Controls”
