1 Spring Seminar NALMCO 2017 SPRING SEMINAR Eric Haugaard Airport Apron Lighting LED Upgrade Case Study March 29, 2017 Existing Challenges Excessive Maintenance Costs and Disruption Slips and Falls Pilots Complaining About Glare Poor Color Quality/Visual Acuity 1

2 Existing Solution 1000W HPS (4 Per Pole) ~4400 Watts Per Pole Luminaire Mounting Heights Range From 25 to 84 Average Pole Spacing is ~180 Poles are Located at the Perimeter of the Apron Area Airfreight Apron Lighting Design and Installation Activity Site Assessment/Review Vehicle and Pedestrian Activity Existing Illumination Conditions Lighting Design Mission Segregate the Space Based on Activity and Best Practices Educate and Engage the Customer in the Design Process Airfreight Apron Lighting Design and Installation Activity Develop Recommended Solutions and ROI Data Use IES Recommended Practices Recommended Solutions Shall Exceed IES Minimum Requirements Demonstrate the Value of Improved Color Quality Mock Up and Fine Tuning 2

3 Apron Lighting Activity Areas Cargo Handling and Service Areas Vehicular/Pedestrian Areas Aircraft Taxiway Apron Lighting Activity Areas Goal: Right size the Delivered Illumination Performance Become the Customer s Trusted Lighting Advisor Lighting Design and Demonstration Processes Will Prove to be the Highest Value Elements of the Final Solution Apron Area Plan View Light Poles Positioned at Apron Perimeter 3

4 Cargo Handling and Service Areas Motor Vehicle and Pedestrian Activity Areas Aircraft Apron Taxiway 4

5 Initial Mockup/Experiment Discussion Minimize both Capital and Operating Expense Reduce Luminaire Count, Where Possible Reduce Energy Consumption Significantly (> 50%???) Specify Luminaire Aiming Angles That Maximize Pilot Visual Comfort Specify Luminaire Aiming Angles That are as Common & Consistent as Possible (i.e. Same Pitch and Yaw Angle Relative to a Given Datum) Easy to verify Contributes to Highest Probability of Accurate Design to Field Measurement Correlation Accuracy Focus on the Three Application Categories Identified 5

6 HID Floodlight Examples Example: Managing Spill Light Above the Main Beam Significant Light Above Horizontal Symmetric (Above and Below Main Beam) LED Floodlight Solution 6

7 Example: Managing Spill Light Above the Main Beam Significantly Less Light Above Horizontal Asymmetric (Above and Below Main Beam) LED Floodlight Solution Axially Symmetric LED Floodlight Solution Narrow Vertical / Wide Lateral With Sharp Cutoff Above Main Beam 7

8 Mockup Results Illumination Performance Significantly Increased Vertical and Horizontal Illuminance Performance at the Aircraft Cargo Handling and Service Areas Improved Horizontal Illuminance Values and performance (max/min, etc ) values at the Motor Vehicle and Pedestrian Activity Areas Equal to Slightly Improved Horizontal Illuminance Values and performance (max/min, etc ) at the Aircraft Taxiway 62% Energy Savings Exterior to Cargo Bay Illuminance and Color Quality Variance Customer Feedback/Comments The cargo handling & service areas and the pedestrian & motor vehicle areas look great The aircraft taxiway looks dark WHY??? Customer Request: Can you adjust the lights to make everything look more even? 8

9 Final Result Looking Out Toward Runway Out Toward Runway Final Results and Lessons Learned Highest Value Elements of the Process Lighting Design Optical Accuracy Never Before Possible With Incumbent Light Source Technologies Involving the Users of the Lighting in the Testing, Evaluation and Final Recommendations Simple Control Technologies Can Contribute, Substantially, to Overall Value Continuous and/or Step Dimming Networked Control Systems Final Results and Lessons Learned Field Measurements are Difficult Having the Appropriate Measuring Equipment and Skilled Practitioners is of Vital Importance Non Uniform Distribution of Light is Not Generally Accepted as Better Increasing the Illuminance in Some Areas Make the Other Areas Look Even Darker Our Eyes are Terrible Absolute Measurement Devices But Excellent Comparative Devices The Experience of Higher Color Quality Performance Plays a Major Role the Perception of Better Light 9
