1 Emerging Technologies Study Lifecycle: LED Street Lighting Demonstrations, from Design to Delivery Panel: Best Practices in ET Field Testing Nov. 8, Harrison Street Oakland, CA

2 Energy Solutions Company Overview Mission: Create large-scale energy and water savings-related benefits for our clients by implementing market-based solutions and developing policies that contribute to these goals Founded in 1995, currently over 65 employees, Oakland and Long Beach offices Practice Areas: Energy efficiency and sustainability consulting Design, marketing and management of energy efficiency programs, energy cost benchmarking, and engineering services Specialize in developing processes and tools for successfully managing complex programs 2

3 Emerging Technology Experience Eleven utility funded emerging technology demonstrations over 3 years LED street lighting LED parking garage, bi-level parking lot lighting Wireless interior lighting controls - Including Demand Response testing with LBNL Directional LED replacement lamps Wireless CAV-to-VAV HVAC controls Department of Energy GATEWAY demonstrations and reports ETCC-posted reports 3

4 Emerging Technology Study Components Site Selection Test/Monitoring Plans Tools for Monitoring and Evaluation Data Collection, Comparative Photographs Qualitative Surveys Residents, user groups Functional Testing Results 4

5 Site Selection Coordination with client and host facility or location Appropriate demo locations are key google maps and street view images help! Preliminary site visits to characterize location Access agreement Schedules and notifications 5

6 Test/Monitoring Plans Demonstration site details, field and lab assessment overview Energy performance, lighting performance, network controls functionality Field visits Site verification and preparation As is baseline testing - As restored baseline testing Retrofit testing - Functional testing of controls Power monitoring Monitoring details Photometric monitoring - Site photographs Monitoring equipment - Modeling software 6

7 Test/Monitoring Plans #1 Tool for Planning: Standards - RP 8: ANSI/IESNA RP Recommended Practice for Roadway Lighting - LM 50: IESNA Guide for Photometric Measurement of Roadway Lighting Installations - LM 79: Independent Test Lab results for luminaire photometric and electric performance - LM 80: Chip-level lumen depreciation data for product lifetime predictions 7

8 Tools for Monitoring and Evaluation Illuminance: Solar Light SnP Meter Correlated Color Temperature: Konica Minolta Chroma Meter Power: Dent ElitePro Datalogger Digital Camera: Nikon D80 Photometric Modeling Software: AGi32 AGi32: calculation tool for accurate photometric predictions - Performs numerical point-by-point calculations of incident direct or reflected light on any real surface or imaginary plane based on luminaire placement and aiming Additional HOBO Temp / RH logger, laser hypsometers, tape measures, spray chalk, safety vests, cones, safety signs, lots of coffee 8

9 Tools for Monitoring and Evaluation Photometric modeling snapshots 9

10 Data Collection Examples of photometric layouts from monitoring plans Typical illuminance measurement grid: In higher traffic location: - Limited measurement points supplemented with computer modeling 10

11 Qualitative Surveys Resident Surveys Safety driven questions Perceived visibility Neighborhood appearance User Surveys Network controls operators and facility managers - System installation and commissioning - Operation and functionality - Customer support - Overall satisfaction 11

12 Functional Testing Example: system operators demonstrate interface used to manage network streetlights 12

13 Innovations Mesopic Vision and Broad Spectrum Lighting Photopic (cone dominant) vs. scotopic (rod dominant) spectral response curves depending on light levels, visual adaption Outdoor lighting standards based on photopic lumens, but broad spectrum sources emit broadly across visible spectrum, exciting multiple photoreceptors (cones and rods) depending on adaption state Adaptive Lighting Controls Changing light output dynamically through the night, with controls, based on changing conditions - Vehicle and/or pedestrian traffic activity, weather, events Standards written for worst case scenario, but often light levels could be safely lowered 13

14 Results Street lighting energy savings 40% to 60% savings from 100W to 400HPS to LEDs, though often in conjunction to lowered light levels Parking lot bi-level energy savings 57% at full output, 85% at reduced output, 70% average (higher illuminance at all levels!) 14

15 Results Lighting performance Typically reduced average photopic illuminance, though often meeting RP-8 Illuminance Requirements Equivalent or improved uniformity (avg:min, max:min, CoV) Equivalent or increased mesopic illuminance Qualitative satisfaction in almost every case HPS Photopic LED Photopic LED Scotopic 15

16 Results Economic performance Paybacks ranging from 5 years (new construction) to 10+ years (retrofit) Highly dependant on maintenance savings assumptions Costs still coming down 16
