The application, validation and further development of radiance : some UK activities

RADIANCE has emerged as one of the most powerful programs for modelling the luminous environment within and around buildings. It has a large and growing number of users in many countries including the UK. This paper illustrates its use for producing photo-realistic images of proposed building designs and for daylight analysis of a complex atrium building. The results of validation work, using real sky data, are presented and some current UK research involving RADIANCE is described.
