Review the lighting on the University’s buildings and make the following changes to lighting following the five principles for responsible outdoor lighting to reduce the University’s light pollution footprint:
1. Useful
All light should have a clear purpose
Before installing or replacing a light, determine whether light is needed. Consider how the use of light will impact the area, including wildlife and the environment. Consider using reflective paints or self-luminous markers for signs, curbs, and steps to reduce the need for permanently installed outdoor lighting.
2. Targeted
Light should be directed only to where it’s needed
Use shielding and careful aiming to target the direction of the light beam so that it points downward and does not spill beyond where it is needed.
3. Low level
Illumination should be no higher than necessary
Use the lowest light level required. Be mindful of surface conditions, as some surfaces may reflect more light into the night sky than was intended.
4. Controlled
Light should be used only when it is useful
Use controls such as timers or motion detectors to ensure that light is available when it is needed, dimmed when possible, and turned off when not needed.
5. Warm-colored
Use warmer-color lights where possible
Limit the amount of shorter wavelength (blue-violet) light to the least amount needed. Light where you need it, when you need it, in the amount needed, and no more.

Making these changes will result in the following benefits, helping the University make progress towards the sustainable development goals:
•Reduced energy usage due to better designed lighting
•Increased safety on campus due to reduced glare from lighting and reduced contrast between lit and unlit areas.
•More nature on campus as artificial lighting has negative impacts on wildlife and human health.
•Improved observing conditions for astronomy, especially for students using the Oadby Observatory.
