Architectural Engineers and Their Role in Energy-Efficient Lighting and Controls

Architectural engineers play a crucial role in optimizing building energy use through effective lighting design and advanced controls. By understanding visible light and its properties, including subtractive and additive color mixing, they create environments that not only enhance aesthetics but also improve energy efficiency. This involves selecting appropriate light sources such as LEDs, CFLs, and fluorescent lamps, and implementing smart lighting controls like occupancy sensors and daylighting strategies. These innovations significantly reduce energy consumption while maintaining comfort and functionality.
