Site layout planning for daylight IP 23 12
Site layout planning for daylight (IP 23/12) was written by Paul Littlefair and published by BRE on 16 October 2012. It superseded IP5/92 which was withdrawn.
Daylight makes an interior look more attractive and interesting, as well as providing light to work or read by. However, access to natural light depends on the design of the external environment. Large obstructing buildings may make adequate interior daylighting impossible
This 6-page Information Paper outlines revised BRE guidance on site layout planning to achieve good daylighting, both within buildings and in the open spaces between them. It deals with daylight within new developments and in existing buildings nearby. It addresses the provision of daylight in dense urban areas and summarises some of the guidance on diffuse daylighting (ie light from the sky rather than direct from the sun).
This Information Paper should be of interest to developers, architects, surveyors, clients, and planning officials.
Its contents are:
- Introduction.
- Daylight within a new development.
- Existing buildings.
- Trees and hedges.
- Conclusions.
- References.
