CUMULATIVE SKY LUMINANCE DISTRIBUTIONS FOR DAYLIGHTING DESIGN
Authors: Hayman, Simon
Despite progress in the development of standard skies, there has been limited development on how these new
models will be implemented in design. Without this the tolerances associated with modelling could be greater
than the expected benefits. Practical daylighting design comes not from the instantaneous application of a
standard sky for all possibilities but from a technique that embeds variation. To this end, cumulative luminance
distributions have been explored. Such distributions can be generated from measured data, and examples are
given for Sydney, or synthetically generated from appropriate sky models.
