LearningObjectives

At the end of the this course, participants will be able to:

1. Understand the new Next Generation Luminaire Systems competition.

2. Assess preliminary specifications for connected lighting systems.

3. Assess evaluation criteria for connected lighting systems.

4. Engage with the upcoming phases of the competition.

Is LED Lighting Old News?

Shifting focus from luminaires to connected lighting

NGL – Past and Present

Building off what we have learned

Connected Lighting Pilot 2016

2017 Big, big changes

What we are trying to learn

How you can be involved

Partnerships link energy efficiency & lighting quality

Mission: support the effective application of solid-state lighting in the general lighting market by focusing on high-quality, high-performance SSL products that achieve significant energy savings and deliver lighting quality

Hands-onvisual

deliberativedocumented

2008: Focus on LED luminaires of different types.

2012: Split into separate Indoor and Outdoor Competitions

2015: Focus on controllability and serviceability

2016: Focus on specific applications and connected systems

From Next Generation Luminaires to Next Generation Lighting Systems.

2017: Exclusively Indoor Connected Lighting Systems Build on 2016 experience

Separate into levels of system complexity and performance

Permanent installations

Ongoing evaluations

Emphasis on specific applications:

High-lumen capabilities in general area luminaires

Controllability

Pedestrian-scale outdoor

Sensor-integrated garage

25 indoor and outdoor luminaires recognized

Nearly 80% of entries exceeded L85 at 50,000 hours

Over 30% of entries had greater than 90 CRI

Dimming was a critical criteria (rather than bonus)

Installation/configuration

External controller with networked luminaires

Self-contained network (all logic on board)

Benefits: Robust control functionality, typically can interface with BMS Many options for luminaire styles Well suited for new construction and complex projects

Limitations: Dual points of responsibility More complicated installation More complicated start up and commissioning Cost for smaller projects

Manufacturer supplies control system, luminaire by others

Benefits: Integrated solution, single point of responsibility Simple installation, start up, and commissioning Well suited for retrofits and smaller projects

Limitations: Limited control functionality Limited options for luminaire styles

Integrated fixture/control “out of the box”

Three of four entries judged “Notable” – each had strengths and limitations, limiting useful conclusions.

How do you know how system capability matches to project needs (mostly by experience today)?

How do you know that you have correctly configured a system – is professional commissioning necessary?

In practice, if a system fails to meet expectations, is it capability, configuration, or defect?

More robust evaluation setting (sensors)

Better configuration process
