able and supported by a minimum five-year warranty. Reported capabilities provide additional information. These include control persistence; building automation system integration; energy and/or device monitoring (and remote diagnostics); user interface type; operating and standby power; and scheduling, load shedding, personal, and plug-load control. In June, the DLC released V2.0 of the specification, which built on V1.0 to add requirements for exterior light- ing control systems and adding new information such as application program interface, color tuning, start-up and configuration, and security information. The most signifi- cant change is in differentiating interior and exterior sys- tems with separate required and reported features. For example, the DLC requires interior systems to have occu- pancy sensing but requires exterior systems to have either occupancy- or traffic-sensing capability. The result is a list of products that utilities can use for rebate programs and distributors can use as a tool to com- pare highly individualized solutions from manufacturers in a standardized format. As of August, the QPL listed 19 products from 15 manufacturers; these products were in the process of being requalified based on the new spec. “For building designers, specifiers, distributors, contrac- tors, and end-users, the new QPL provides a valuable tool to identify and compare potential control systems for their projects based on their capabilities and characteristics,” said Gabe Arnold, technical director, DLC. “All of the listed systems have been carefully reviewed to meet minimum performance standards, will provide significant energy sav- ings, and are prequalified for utility rebates.”
Arnold explained that more than 20 energy-efficiency pro- grams now require networked control systems to be on the QPL. His main goal, however, is for new rebate programs to be created promoting the technology. As of August, about a dozen rebates had been created by utilities and programs—including Baltimore Gas & Electric (BGE), Pacific Gas & Electric (PG&E), and Wisconsin Focus on Energy. And while a DLC goal is program standardiza- tion, there is currently no consistent approach among utili- ties as they experiment with models. “We are excited about the momentum we are hearing about from the utilities and energy-efficiency programs,” Arnold said. “Most of them are actively looking at how to incorporate the technology and QPL resource. They see this technology as essential to achieving their current and fu- ture energy-efficiency goals. That said, it will take time for some utilities to develop these new rebates because this technology is not as simple as incorporating an LED light fixture measure into a program.” BGE, for example, takes a simple prescriptive approach.
It awards $50 to $80 for a DLC-qualified LED troffer. Cus- tomers can earn another $40 per luminaire if they incor- porate DLC-qualified luminaire controls. PG&E’s LED Accelerator Program bases its networked lighting control rebates on energy saved. It awards $. 17 per k Wh and $150 per k W if DLC Premium luminaires are installed. The rebate increases to $. 24 per k Wh and $150 per k W if DLC-qualified networked lighting controls are also installed. Wisconsin Focus on Energy, meanwhile, rolled out a rebate based on an entirely new approach. Customers can receive either a $.125- or $.25-per-square-foot rebate if a DLC-qualified networked control system is installed, de- pending on the application. An additional $.05 per square foot can be earned if the system features energy-monitoring capability and the customer agrees to share energy data with the utility or energy-efficiency program. “We see the utilities serving a critical role in accelerating the adoption of the technology, both near and long term,” Arnold said. “As they did with the introduction of LED, many utilities will offer higher-than-normal rebates at the early stages to jump-start the technology adoption. This will in turn help drive greater volume, and with this greater
