The document discusses sustainable parking design and green building strategies for parking structures. It covers topics like the LEED rating system, green roofs, renewable energy, electric vehicles, pervious pavement, efficient lighting options, and case studies of parking structures with sustainable features.

38. Lighting 10-Year Life Cycle Cost Analysis

50. High Pressure Sodium Lighting High Pressure Sodium Advantages High Pressure Sodium Disadvantages Lower First Cost Nearing Obsolescence in Parking Match Existing Facilities…If Not Retrofitted Already Yellowish Light Color Lower Operating Cost Than Metal Halide Shorter Lamp Life than Newer Technology Higher Lamp Cost than Fluorescent Higher Energy Consumption Higher Life Cycle Operating Cost

51. Metal Halide Lighting Metal Halide Advantages Metal Halide Disadvantages Lower First Cost Nearing Obsolescence in Parking (TBD) Match Existing Facilities…If Not Retrofitted Already Highest Energy Consumption White Light Higher Life Cycle Operating Cost Shorter Lamp Life than Newer Technology Higher Lamp Cost than Fluorescent

52. Fluorescent Lighting Fluorescent Advantages Fluorescent Disadvantages Lowest First Cost Perception of Lower Quality – Some Poor Quality Fixtures on the Market Lowest life Cycle Operating Cost Reduced Illuminance in Cold Weather White Light Disposal of Lamps with Mercury Low Energy Consumption More Maintenance (Cleaning, Gasket) Lowest Lamp Cost Long Lamp Life Instant On / Off For Lighting Management

53. LED Lighting LED Advantages LED Disadvantages Low Energy Consumption Highest First Cost Long Life…But, a Moving Target Replace Entire Fixture When LED’s Fail White Light Some Poor Quality Foreign LED’s No Mercury Disposal Light Distribution: Glare, Little Up Light, Less Uniform Great in Cold Climates Little History…Rapid Change Instant On / Off For Lighting Management Lumens per Watt is too Low

54. Induction Lighting Induction Advantages Induction Disadvantages Low Energy Consumption Higher First Cost than Fluorescent Long Lamp Life More Fixtures Required Due to Low Light Output White Light Lumens per Watt is too Low Great in Cold Climates Some Poor Quality Foreign Lamps Instant On / Off For Lighting Management Good Light Distribution
