More building owners and managers are considering intelligent lighting systems to cut energy use because lighting, on average, accounts for approximately one-quarter of a building’s overall electricity use, rivaled only by HVAC and office equipment, according to Gary Meshberg, LEED, AP.

State-of-the-art lighting systems reduce costs, demonstrate an overall commitment to being environmentally friendly, as well as contribute toward higher building values, higher tenant retention rates and overall end-user satisfaction, said Meshberg.

As an example, Encelium Technologies’ Energy Control System (ECS) uses addressable networking technology in combination with advanced control hardware and software, which can be integrated with HVAC, security and irrigation systems.

Installation of an intelligent lighting system also provides a significant return on investment (ROI), said Meshberg.

As an example, the Rogers Centre sports and entertainment complex in Toronto, with approximately 7,000 light fixtures, cut its energy use by 77 percent, or by 3,731,000 KWh annually according to Meshberg. The complex also achieved a 39 percent reduction in energy demand and a savings of 76 percent for energy costs. This translates into a cost savings of about $300,000 per year for the complex.
