Luminaire Level Lighting Controls

Description:

LLLCs have sensors and controls within individual fixtures that enable them to be controlled remotely or on a case-by-case basis. Remote control allows users to adjust the programming criteria or illumination levels without replacing the fixtures. In conventional lighting systems, lighting zones are defined as a collective unit and thus are centrally controlled. LLLCs however, incorporate sensors into each fixture, such as occupancy, daylight, temperature or receive/broadcast signals. Each fixture has the potential to become a semi-autonomous zone that is capable of responding to small changes in the area under each fixture. Furthermore, individual fixtures can communicate with other fixtures, using wireless or infrared signals, to share data for an even greater potential to increase energy savings and user satisfaction. Some LLLCs can be connected by gateway to transfer information collected. This data is analyzed, usually through manufacturer’s software, to provide a user interface different from a typical text editor. From there users are able to identify trends in occupancy and lighting energy consumption that can then be used to refine the building schedules for occupancy and lighting and, if applicable, for the buildings’ HVAC schedule programming.

Learning Objective 1: 
Participants will be able to describe the difference between the standard zone based control strategy and the flexible/individual fixture based approach that LLLCs provide; Increased granularity translates to increased energy savings.
Learning Objective 2: 
Participants will be able to discuss the impact LLLCs will have on the industry as a turn key solution, but also, LLLCs being a direct result to address and meet increasingly strict lighting standards/codes now and in the future.
Learning Objective 3: 
Participants will be able to identify where the best uses for LLLCs; i.e. schools, hospitals, and offices as well as any pros or cons that are associated with that building or space type that would use LLLCs.
Learning Objective 4: 
Participants will be able to illustrate the cost savings and utility incentives (Northwest), but also, the impact it will have the return of investment. Furthermore, they will also illustrate the impact each step in a control strategy will have on control strategies savings, however, the importance of occupant comfort will be used to compare the highest energy savings scenario vs meeting occupant

Dylan Agnes
Research Scientist I
Biography: 
After earning a Bachelor of Science degree in Architecture from the University of Idaho, Moscow, Dylan studied the science and engineering of building design by completing a Master's degree in architecture. As a student he worked at the Integrated Design Lab and gained hands-on experience in the practice of Integrated Design. As an IDL Research assistant, Dylan worked with both the architectural and engineering side of integrated design, providing a broader opportunity to cross over fields of study. He started working on real world projects at the Lab in the spring of 2015 and, graduated with a Master's of Architecture in Fall of 2017 with an emphasis in urban planning and net-zero/energy efficiency building design. Shortly after graduation Dylan began working as a Research Assistant at the IDL and has since been working on a wide range of projects from Energy Modeling to Daylighting Design.
