To ensure that external lighting is concentrated in the appropriate areas and that upward lighting is minimised, thereby reducing unnecessary light pollution, energy consumption and nuisance to neighbouring properties.

• Minimise nuisance to neighbouring properties due to lighting.
• Maintain an adequate level of safety and security lighting on the site.
• Reduce energy use by designing coverage and control systems that are appropriate for the development.

The external lighting used by buildings can have a detrimental impact on the use and enjoyment of neighbouring properties, and on the mental and physical wellbeing of individuals in them. It also has a significant and often detrimental impact on local wildlife.

The design of lighting installations can reduce the impacts without limiting their functionality and there are a number of appropriate best practice standards for the design and control of such lighting installations that aim to minimise these detrimental impacts.

By limiting light pollution the impact and energy use of the building may be reduced making it more acceptable to local communities and reducing impacts on local wildlife.
