1. Prepared by the Evaluation and Development of Potential Solutions of Significant Areas of Light Pollution and Dissemination of Findings Proposal for the

2. During the last decade, -light pollution had negative biological effect on plants and animals, -light trespass provided glare and sky glow affecting our nighttime view of the stars, wasting energy, water, and exhausting our natural resources, -and inefficient light had adverse effects on nighttime safety

4. Study of Current U of A Campus at Night

5. Non-cutoff vs. Cutoff Fixtures Targeting Non- usable Spaces Discontinuous Lighted Paths High Efficacy & Coefficient of Utilization Glare and Blinding Effects Light Fixtures Integrated on Building Exteriors Undirected Lighting: Sky Glow and Light Trespass Building Entrance Lighting Current Problems

6. The scope of our larger proposal includes Four Phases ; 1. Development phase 2. Dissemination phase 3. Implementation phase* 4. Assessment phase* * Not included in this proposal

7. The current proposal focuses on the first two phases ; the development phase and the dissemination phase, which are divided into six stages to be conducted over a total period of two years, dedicating one year to each phase. DEVELOPMENT PHASE 2005 DISSEMINATION PHASE 2006

8. STAGE 1 -Nighttime aerial photographs Preliminary Assessment for Campus Outdoor Light Pollution

9. STAGE 2 -Evaluation of aerial photographs using GIS -Determination of six typologies: -Circulation space -Parking lot -General activity space -Transitional space -Roof -Minor sports activity area -Ground-level assessment Targeting Light Pollution Areas

10. STAGE 3 Acquiring Detailed Data -Quantitative inventory of luminaires -Existing conditions surveys of physical context -Documentation of materials and reflectivity values

11. STAGE 4 Spatial Data Interpretation and Analysis Using GIS -Photometric measurement of light intensities -Calculation of energy consumption and costs -Collect crime and safety statistical data -Variables entered into ArcGIS software for spatial statistic analysis -Spatial autocorrelations among variables for causal relationships

12. STAGE 5 Developing Design Solutions and Recommendations -Construct physical models for each typological location -Simulate scale models with variable light source intensities and variable physical form and material -Develop design solutions and recommendations (**including student competition for luminaire design) -Simulate energy, resource and cost savings -Regenerate night sky image with computer rendering software

13. STAGE 6 Dissemination and Education -Prepare, edit and compile dissemination materials -Conduct short-courses -Facilitate one-day workshops
