Daylighting and sunlighting
Published October 2012
Effective from October 2012
Reissued October 2023
This professional standard 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.
This document was reissued in October 2023 as a professional standard. It had previously been published in October 2012 as a guidance note. No material changes have been made to the document.
