[esp-r] Re: Solar multiple tramsmission

[Achim Geissler]

two thoughts: 1) Quite large for a double facade ;o). Maybe an obstruction
pattern with reduced area such that transmission is equivalent is easier
(however, the max number of obstructions may be limiting). 2) Why is
tracking solar to high detail important for the analysis? If it is daylight,
then coupling with Radiance would come to mind (obstructions for the
“energy” calcs done by ESP-r, actual glazing for the daylight calcs done by
Radiance).

Achim,

Thanks for the contributions.

Cut from the ridge, the section looks like this.
