Over the December holiday break, the Ralph Brown Draughon Library became the first building on Auburn University's campus to install adaptive lighting.
Adaptive lighting saves energy and casts a more comfortable light by adjusting light levels to a set brightness depending on the amount of outside light coming into the building. On bright days the adaptive lighting turns its system to a low intensity or off entirely to keeping lighting at the set level. On cloudy days the system augments light. At night the lights come up to full power.
The three alcoves with large windows on the library's Fourth Floor were chosen for this initial installation because of the great amount of light coming into the building at these locations. The system, funded by Auburn University Facilities, uses a low-voltage LED (light-emitting diode) system, resulting in significant energy savings and a rapid return on the equipment investment.
