rigorously validated (<a

) render engine Radiance (<a href="http://radsite.lbl.gov/radiance/">http://radsite.lbl.gov/radiance/</a>
) as its underlying calculation engine. However, it should be pointed out that ‘integration’
means that IF you have the Pro version of SU, THEN you can export to the .3ds file
format that the Daysim program will import. The author, Christoph Reinhart, has
referred recently to Daysim 3 being in the process of validation and incorporating
some of the newer daylight performance metrics – but no reference to
greater integration with SU.<o:p></o:p></span></p>

exporter. Saved scenes become saved viewpoints in Radiance. Materials and skies
can be defined within SU prior to export. There is as yet no render control ‘button’
within the exporter interface, but everything else is there. Running Radiance
of course requires a knowledge of Unix (see <a
href="http://luminance.londonmet.ac.uk/learnix/">http://luminance.londonmet.ac.uk/learnix/</a>
) or having a copy of Ecotect’s Radiance Control Panel (<a
