Light up your campus!

This plot represents the EPFL campus during the night. Your objective is to place some street lamps to illuminate the campus, while minimizing the CO2 emissions. You can play with the intensity of each street lamp and its position on the map. You have as direct feedback the CO2 emissions of your current configuration, as well as the total Lux emitted (the integral of the light sources on the map). Good look in finding the best configuration!

Assumptions:
The intensity of a light is expressed in Lumens. We used some approximations to make the problem easier:

1. For lighting residential areas, the average is 5000 lumens. For roadways, highways, building perimeters, universities, it can range from 6,400 to 18,000 lumens
2. 10000 lumens emits around 1kg CO2 per hour (this is just a rough estimate, it mostly depends from the technology)
3. The light source is considered a point light in a 2D plane, so the intensity decreases with the square of the distance

CO2 Consumed Per Hour (kg): 0.00

Total Intensity (MLx): 0.00

How many 🌲 should you plant by year to compensate this carbon footprint?
