LG10: Daylighting - a guide for designers (2014)

This guide takes the reader through the process of designing for daylighting, addressing the issues of aesthetics and building physics that lie at the heart of the discipline of architecture. This requires architects to understand the basic aspects of the engineering of light, and engineers to have a grasp of aesthetics. The format of the guide parallels the design process, beginning with outline considerations of form and orientation and leading on to the more detailed aspects of designing the building envelope to admit or to filter natural light through different shading systems. It also deals with the multitude of different visualisation techniques that allow the design team to explore the appearance of design solutions. In addition, it provides a guide to more detailed resource material.

The document has been written primarily for use when new design work is to be undertaken. However, much of the guidance will be applicable to refurbishment projects. The guidance in this document is written primarily for buildings located within the UK, and will be most applicable to projects in northern hemisphere temperate climates. However, the principles are universal, and can be applied to other locations if the appropriate weather data is used and local standards and regulations are respected

This edition of LG10 supersedes the previous edition, CIBSE Lighting Guide LG10: Daylighting and window design, which was published in 1999, and which is now withdrawn.

A Corrigendum in the form of a replacement page 77 was issued in December 2014 to correct an issue with the Sunpath diagram. This has been corrected in the downloadable pdf and will be supplied to purchasers of the hard copy but can also be downloaded separately here.
