[Radiance-general] Radiance Ecotect 2011 and Ecote'ct v5

[Jack de Valpine]

Hi Alexis,

Ecotect uses an entirely different method for calculating daylight 
factors than Radiance. If I recall correctly, it uses a split flux 
method with relatively coarse sampling. So at best this might be useful 
for a very very simple room (and perhaps even then for an initial 
approximation). Radiance on the other hand uses much more sophisticated 
methods and is capable of dealing with very complicated geometry. 
Christoph Reinhart at Harvard has done some work on this.

Regards,

-Jack
