Evaluation and Development of Potential Solutions of Significant Areas of Light

Pollution and Dissemination of Findings

Proposal for the

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

Study of Current U of A Campus at Night

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

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

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.

DEVELOPMENTPHASE

2005

DISSEMINATIONPHASE

2006

STAGE 1

-Nighttime aerial photographs

Preliminary Assessment for Campus Outdoor Light Pollution

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 assessmentTargeting Light Pollution Areas

STAGE 3

Acquiring Detailed Data

-Quantitative inventory of luminaires

-Existing conditions surveys of physical context

-Documentation of materials and reflectivity values

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

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

STAGE 6

Dissemination and Education

-Prepare, edit and compile dissemination materials

-Conduct short-courses

-Facilitate one-day workshops

We are in the process of developing:

1. Community Partnerships

2. Funding Sources Possibilities
