BREEAM Reduction of night time light pollution
The aim of this credit is to reduce unnecessary light pollution, energy consumption and nuisance to neighbouring properties by ensuring that external lighting is concentrated in the appropriate areas and that upward lighting is minimised.
 When to consider
 Questions to ask while seeking compliance
- Does the building have external areas which require external lighting?
- Is the building an infill building on an existing site or an extension to an existing building?
- Will there be any safety or security lighting required?
- Are there any illuminated advertisements on the development site?
 Tips and best practice
- Double-check that any drawings, schedules or specification details provided for the Health and Wellbeing: Visual comfort (external lighting section) and the Energy: External lighting credits match up with information provided for reduction of night time light pollution.
- Confirm with the end user (where known) what the site’s operational hours will be. Bear in mind that a number of industrial sites may be in operation for 24 hours a day, 7 days a week, and therefore external lighting will be required throughout the night.
 Typical evidence
 Design Stage Evidence
A site plan indicating external lighting (both locations of light fittings and types). A schedule of external light fittings may also be provided. For confirmation of compliance with the relevant guidance or luminance requirements at design stage, a formal letter from the electrical engineer may be provided.
 Post Construction Stage Evidence
As Built issue of the external lighting plan, and confirmation of any changes to the external lighting specification since design stage (confirmation that the external lighting specification is compliant with the relevant guidance or luminance requirements).
 Applicable Schemes
The guidelines collated in this ISD aim to support sustainable best practice in the topic described. This issue may apply in multiple BREEAM schemes covering different stages in the life of a building, different building types and different year versions. Some content may be generic but scheme nuances should also be taken into account. Refer to the comments below and related articles to this one to understand these nuances. See this document for further guidelines.
