BRE BR209 PDF

The new edition of this highly regarded BRE guide has been fully revised and updated. It gives advice on site layout planning to achieve good sunlighting and daylighting, both within buildings and in the open spaces between them. This authoritative document is widely used to provide advice during the planning and design stages of building development in the UK and Ireland. New material in this edition covers dense urban areas, trees and hedges. The report is intended to be used in conjunction with the British Standard Code of Practice for daylighting.

Guidance is given on site layout for good sunlighting and daylighting; safeguarding of daylight and sunlight within existing buildings nearby; and the protection of daylighting of adjoining land for future development. A special section deals with passive solar site layout. Guidance is given on the sunlighting of gardens and amenity areas. Issues like privacy, enclosure, microclimate, road layout and security are also reviewed. The appendices contain methods to quantify access to sunlight and daylight within a layout; one transparent direction finder is included for use with these indicators that calculate access to skylight, sunlight and solar radiation. Rights to light are briefly discussed.

Purchasable separately: Sun-on-ground indicators (AP288) is a set of 12 transparent indicators, designed for use with BR209, which have also been revised and updated. They can be used to predict the availability of sunlight on the ground at the equinox at three different latitudes in the UK.
