Louvers on Solid Surface

Dear all, I need to know the best way to model aluminum louvers that is placed on an exterior brick wall on a southern elevation. Should I create exterior walls that resembles the louvers for each zone,, or assume a very low U-value for this wall, or there is an appropriate way that the software allow for this case?
Any help would be highly appreciable,
Regards,

The louvers are there to shade the wall and reflect the sun for the south exposure, no? If so, you can model a bunch of individual shades that match the configuration of the louvers. Or, you can make one big shade if the sun will never hit the wall...

Sorry, hit the send button too soon....

Shades on well-insulated opaque exterior walls have only a modest impact on overall annual energy use. So, your modeling effort should be proportioned accordingly. If the shades are shading windows then the effect is worth the effort. However, don't forget DOE-2 uses the split-flux method, which is a good algorithm, but has its limits.

See the MS thesis by Sikjoon Oh on our web site for details.
