By configuring the least amount of energy needed to achieve desired lighting effects, the Quantum system can cut building lighting costs by up to 60 percent, according to the company. Both electric and natural light sources are used to illuminate rooms; automated window shades admit daylight when available, and electric lights are dimmed or switched off when no longer necessary. To minimize maintenance costs and provide feedback for further cost savings, the Quantum system monitors and reports on lighting use throughout the facility.
