Developing Flexible, Networked Lighting Control Systems That Reliably Save Energy
Seamless Integration of Networked Lighting Controls with Whole Building Automation Systems
This project developed a suite of networked lighting solutions to reduce lighting energy use in buildings: a) a low-cost sensing, distributed intelligence and communications platform, the "PermaMote," b) a task ambient daylighting system that integrates sensors with data-driven daylighting control using an open API, c) a new method for evaluating and specifying lighting systems' performance, d) a proposed lighting data model and user interface elements, which contributed to the ANSI Lighting Systems Committee (C137), and e) a metric for capturing the actual energy impact of a lighting system over time. Laboratory validation of the technologies showed significant energy savings, up to 73% for the PermaMote sensor system. These advanced technologies can reduce California commercial-building lighting energy use by 60-80% or about 1,500 GWh/year in savings.
The recipient is developing low-cost lighting components with open communication interfaces, that allow seamless integration into whole-building control and automation systems. The project targets future California Building Energy Efficiency Standards (Title 24), and establish methods by which the site-specific configuration and operation of networked lighting controls systems can be effectively addressed, and more easily implemented in the marketplace.
The technology could reduce energy consumption and costs associated with lighting energy use in commercial buildings by an estimated 60 to 80 percent. Additionally, one of the goals is to develop low cost lighting components which could facilitate easier implementation into the marketplace.
