Dear RADIANCE users,
 
The purpose of this message is to inform you of a RADIANCE add-on that might
be of interest to some you.
 
The National Research Council of Canada and the Fraunhofer Institute for
Solar Energy Systems have developed a RADIANCE-based dynamic daylight
simulation method called DAYSIM that allows you to efficiently simulate
annual indoor illuminance profiles at points of interest in a building.
DAYSIM is based on Tregenza's daylight coefficient approach and the Perez
sky model. DAYSIM further features a method to simulate the short time steps
dynamics of daylight, creating 1 min-time-series of external direct and
diffuse irradiances based on hourly means. This model is a modified version
of an older approach from Olseth and Skartveit.
 
DAYSIM is now available for download from
<http://www.nrc.ca/irc/ie/light/daysim.html>

welcome.  
 
Greetings from Ottawa,
 
Christoph
