Solar vector, radiation and shading devices

Hello everybody,

I need help for an optimization issue. I'm trying to design shading panels for a surface divided in diamond glass panels (similar to Singapore Esplanade project).

I have:

- Radiation study for each panels, summer and winter,

- Summer solar vectors (extrem values that i want to block) and winter solar vector.

I think there is two solutions to design the shading:

- We could minimize the radiations in summer and maximize them in winter (using Galapagos or Octopus linked to ladybug analysis), but it involves to have a gene pool with thousand of genes (each shading panel must move independently for each glass panel....impossible

- we could use the solar vector directly to design and adapted shading device for each panel, but I can't go any further that the solar vector in the centroid of the panels...There is may be a relation between the slope of the panel, the solar vectors and the radiation that could be used?

I can't progress, all suggestions are welcome!

I'll prepare a small demo on that matter (but it's in C#, not using any component).

In the mean time I would strongly suggest to evaluate (cost VS benefits, lifetime maintenance, cleaning, MTBF data ... blah blah ... AND ultimately: investment break even point) the moving parts/components approach VS the new trend (NO moving parts + SMART glass/panels + PV panels).

If you do that you'll discover the unspeakable truth: in 99% of "Eco-friendly" cases/designs instead of saving the polar bears ... you just make circles around yourself.

more soon, best, Peter
