Daylighting and sunlighting

This guidance note is about daylight, sunlight and shading and, to a lesser extent, how it is dealt with in the design, planning, and environmental impact assessment of developments, and particularly in relation to the Building Research Establishment Report: Site layout planning for daylight and sunlight 2011, which sets out the standards and methods of calculation most usually relied upon by local authorities when assessing planning applications.

Surveyors advising on daylight and sunlight need to ensure that they are familiar with that document and with the planning policy of local authorities to whom reports are to be submitted.
