2 Agenda Background Why retrofit kits? Goals for the specification Building owners/managers (e.g., Better Buildings members) Manufacturers/distributors Draft specification highlights General product characteristics (e.g., warranty, lifetime, etc.) Performance metrics How you can help Q&A 2

3 Background

4 Better Buildings Initiative Launched 2011, Now 250+ Partners & Allies Commercial, Industrial, Public, Private Represent: 3.5+ Billion Square Feet $5+ Billion Private Financing 650+ Manufacturing plants $4 Billion Federal Commitment Goals: Make commercial, public, industrial and residential buildings 20%+ more efficient in 10 years Save more than $80 Billion+ on energy bills for US organizations Create American jobs How: Leadership Results Transparency Best Practice Models Recognition Catalyzing Action 4

5 Troffer Specification A Success Story Introduced in 2011 Today s troffer specification can save: Roughly 50% by its adoption * Up to 80% with use of controls Best practices guidance 5 * Over typical fluorescent troffers

6 Why retrofit kits?

7 Retrofit Kits A Viable Compromise UL Type A LED Tubes Good for: Energy savings Low first-cost No add-on labor cost Challenges Control compatibility Energy savings left on table Dated luminaire Luminaires Good for: Best energy savings Control options Longest life Essentially maintenance-free Challenges High first cost Labor cost to install 7

8 What Is a Retrofit Kit? A system that provides upgrading/updating an existing luminaire by: Removing existing components Installing new components that typically include: LED light engine(s) LED driver Sensor(s) Other optical / mechanical / cosmetic hardware Driver Sensor(s) 8 Source: Philips EvokitSR

9 Benefits of Retrofit Kits Over TLEDs Provide new/modern look to weary fixture Replaces old ballast with new driver Eliminating inefficiency of having ballast in-line Allows for similar sensor/control options as LED luminaires Dimming ready options Sensors/controls integrated into product Work with wireless control systems 9

10 Retrofit Kits and Controls Take advantage of controls Occupancy Dimming Daylight sensing Integrated sensors Advanced controls possible New driver/electronics 10

13 Goals for the specification

14 A Challenge Specification Drive new product development Top notch efficacy Encourage integration of controls Provide value to customer ROI through energy savings Innovative use of control/communication By Bernhard (Own work) [CC BY-SA 2.5 ( via Wikimedia Commons

15 Guidance for BBA, ILC, NGLS, others Specification leveraged by various programs for guidance and to create product pull and acceptance Better Buildings Adopt Apply Create pull Interior Lighting Campaign Educate Promote Assist Demo Recognize Report (case studies) Next Generation Lighting Systems Competition Recognize 15

16 Increased Acceptance of Retrofit Kits Education and awareness Through ILC, NGLS, and other channels Document and demonstrate successful implementations Case studies, demonstration projects Enable considering retrofit kits as viable choice in projects Specification provides the foundation (and comfort level) Overarching goal Increase adoption of control-enabled products 16

21 Performance Efficacy and Light Output Photometric Performance for Fixed CCT Retrofit Kits Category Minimum Initial Delivered Lumens * Minimum Luminaire Efficacy (LE) Zonal Lumen Density (ZLD) Spacing Criteria (SC) Troffer 375 A lum 140 lm/w ZLD: 75% total lumens Within 0 60 Zone SC: Plane or Plane Linear Ambient 375 L lum 140 lm/w ZLD: 40% total lumens Within 0 60 Zone - Low Bay 5, lm/w ZLD: 30% total lumens Within Zone - High Bay 10, lm/w ZLD: 30% total lumens Within Zone - *A lum and L lum refer to the area or length, respectively, of the luminaire being retrofitted (e.g., a 2 x 4 troffer s Area is 8) Retrofit kits are to be tested in Approved or Pre-approved Equivalent Housings as described in the DesignLights Consortium specification ( The ratio of center-to-center fixture spacing to mounting height (ceiling-to-workplane) Typical commercial light fixtures: lm/w Typical industrial light fixtures: lm/w

22 Performance Tunable White Allow adjusting correlated color temperature of light output Benefits observed in some applications (e.g., healthcare ) Photometric Performance for Tunable White Retrofit Kits * Category Minimum Initial Delivered Lumens Minimum Luminaire Efficacy (LE) CCT**: Min CCT 3500 K Max CCT Min CCT 3500 K Max CCT Troffer 335 A lum 375 A lum 375 A lum 125 lm/w 140 lm/w 150 lm/w Linear Ambient 335 L lum 375 L lum 375 L lum 125 lm/w 140 lm/w 150 lm/w Low Bay 4,450 5,000 5, lm/w 140 lm/w 150 lm/w High Bay 8,900 10,000 10, lm/w 140 lm/w 150 lm/w *The spacing criteria and zonal lumen density requirements for tunable white retrofit kits are the same as those for fixed CCT retrofit kits ** Provide LM-79 reports at the minimum CCT in the range, 3500 K, and maximum CCT in the range in Approved or Pre-approved Equivalent Housings as described in the DesignLights Consortium specification ( See, for example,

23 Sensors/Controls Required (integral) Dual-tech occupancy Daylight Sniffer (on request) Sensor network (on request) Dimming capable Various methods allowed No phase-cut or step dimming Optional VLC Source: CREE Smartcast Technology Source: Leviton Dimmers

24 Installation Retrofit kits require: Removal of various existing components (lamps, ballast, diffuser, etc.) Installation of new components (light modules, drivers, etc.) Rewiring to new electronics Will likely require a qualified electrician for at least some portion of the installation 24

25 Installation Specification Requirements Compatibility list Luminaire models known to fit Luminaire types generally known to fit Tools required Step-by-step instructions Installation time Experienced installer First touch to last 25
