BRE guidelines for daylight and sunlight assessment

The Council applies guidance targets from the Building Research Establishment guidelines BR 209 'Site Layout Planning for Daylight and Sunlight: A Guide to Good Practice' when assessing overshadowing and loss of light in new residential development.

In further assessing overshadowing/loss of light, the Council will generally apply guidance targets within the latest edition of the Building Research Establishment (BRE) guidelines "Site Layout Planning for Daylight and Sunlight: A Guide to Good Practice (BR 209)". BRE 209 provides guidance on avoiding unacceptable impacts and sets out non-mandatory targets for levels of daylight and sunlight within existing and proposed development.
