For the facade system I want to design something that allows some sun to filter though so it gives a scattered light effect though out the day!! The western side of the building needs most protection from the sun as there is nothing else to shade that side of the building and on the north eastern side there is the green house that won't work if it is shaded...
I did some research or facade systems and I came across Toyo Ito's facade of Suites Avenue Aparthotelin barcelona..

I tried to recreate this effect however I thought that if the pattern ran vertically along the side of the building and wrapped over the main exhibition space then it would give me the filtered light effect I was looking for (as the sun would move over the north of the building it would hit the roof and allow some light though...)
I made an example of how it would look using sheet metal.. this clearly more fluid than the actual design would be as it is so thin and easy to bend...
I tried doing it with plastic as well but didn't really work as the plastic was to rigid and didn't move the way I wanted it to...
it seemed to work well with paper as well (it was supported by wire underneath to help it keep its shape...)
The system would need to be attached by a space frame or something similar, this would allow for each curve to placed in the exact right place to ensure that the sun filtered thought at the right angles...
