Rhino Toolbar for Radiance/Daysim. The toolbar is currently used in five GSD

it in his GSD class as well so you can talk to him about it.) <o:p></o:p></span></p>

EPW files. We are properly validating it right now but I think that it will yield
very similar results to RADMAP. I got the source code form Darren Robinson earlier
this year and modified it a bit so that it can now read in EPW files and you
can select time of day and year intervals for a more detailed analysis. If
Darren is OK with it, I can share the modified code with anybody
interested.<o:p></o:p></span></p>
