ions are probably reflective of the prevailing humidity conditions (I just had a chat about this with my advisor, who incidentally also happens to be on the committee for LM-83).
The Tregenza sky patches considered in daylighting calculations don't do a good job of incorporating the correct size of the sun into calculations. In the figure below, the sun on the right is the one considered for calculations in Daysim. You can get a more accurate answer by considering a more discretized sky, however, I am not aware if that is possible with Daysim (and therefore HB) right now. Therefore, your direct sun calculations are likely to be off somewhat depending on how much of it there is(I'd say overestimated).
The calculations with humid sky, which are on account of the sky itself (and not the sun alone) are likely to be more relevant.
Regarding your questions about studying weathering effects with LB/HB, I have no idea as that is something that I haven't looked into before. I am sure someone else on this list has a more informed opinion on this issue than I do.
Your project, and your approach to it, seems really interesting and I am glad to be having this discussion :).

al structure that might resemble the shell structure of radiolaria - www.radiolaria.org - and then I want to manufacture it via 3D printing. Do you think mesh will be up to it?
Also, whether the mesh will work or not, could you please explain me the process on how you arrived to the mesh i.e. why you used all these components that you have used in your definition? As I do not want to directly copy and paste it, I want to understand on why you used all the other components to arrive to the resulting mesh. This will be a huge favour.
Knowing that the form that i have created is very important, do you think starting with the curves was the right thing or do you have any other way in mind to achieve this form with XYZ parameters?

Ja du hast Recht, ich sollte meine Fragen das nächste mal isoliert hochladen. Sorry für die "wirre" Datei.
Dennoch muss ich echt sagen, dass ich es mega schade finde, dass es einige in diesem Forum gibt die einen echt "runtermachen" indem sie ständig auf Fehler hinweisen und einen für komplett bescheuert halten. Es fällt eben nicht jedem leicht ein Programm ohne zusätzliche Hilfe sondern nur durch Ausprobieren zu erlernen. (Musste ich mal kurz loswerden!) Gut, dass es auch solche wie dich gibt, die einen Mut machen.
Gruß und nochmals Danke!…
" (idiomatic) and easy way of doing things.So here come some basic questions:
Is there a way to create custom components by grouping an existing sub-network together? I'm looking for a way to re-use parts of a program (something similar to subroutines), and to make the network look less cluttered. I found that it is possible to group components (ctrl-g), but this still displays them as separate blocks (too much clutter), and provides no way to re-use a sub-network in such a way that if it is modified in one place, all it's instances (all the places where it is re-used) also get modified.
Is there a component that does nothing, just passes a signal through? Suppose I need to connect block A to blocks B1, B2, B3 (all three get the same input). Then I change my mind, and I decide to connect block C to these three, not A. In this case it will be necessary to change three connections, not just one. I'm looking for an easy way to do this by a single rewiring, not three. (This came up in a practical situation).
Finally, a related question: is there a component that acts as a switch, so I can choose which signal it passes through out of a possible set of choices? For example, suppose that a set of objects can be coloured based on a number of different properties (size, positions, rotation, etc.) I'm looking for a way to switch between these very easily, without the need to do much rewiring.
Thank you in advance for any replies / useful comments, even general ones on how to easily structure a large Grasshopper program/network.…
at 0.85m above the floor.
I copy paste from the Appendix E:Rights to Light of the book "Paul Littlefair, Site Layout Planning for Daylight and Sunlight, A good practice, BRE Press, p.60" which is the primary guide for evaluating the impact of new construction to the Rights to Light of the existing adjustment buildings:
"The accepted way of calculating the loss of light is to compute the sky factor at a series of points on the working plane. In dwellings, the working plane height is usually taken to be 0.85 m (two feet nine inches). The sky factor is the ratio of the illuminance directly received from a uniform sky at the point indoors, to the illuminance outdoors under an unobstructed hemisphere of this sky. No allowance is made for glass losses or light blocked by glazed bars and (usually) window frames; nor is reflected light included, either from interior surfaces or obstructions outside. Thus the sky factor is not the same as the CIE daylight factor (see Appendix C). The sky factor is often calculated using a Waldram diagram, but this is a different Waldram diagram to Figure B1 in Appendix B, which should not be used for this purpose."
Thought couldn't find the specific Waldram diagram for this case from the references, I assume contemporary analytical tools should exist to calculate it.
I used your Vertical Sky Component process and culled the mesh faces lower than 0.2% but I believe because of they type of the radiance analysis as you have explained it before (stochastic method) it doesn't create one continuous edge, as you can see in the attached image.

ka Museum of Design, Gothenburg, Sweden. With
perforations that sift the light and with joints that are put together by
hand, it serves as a focus point in the big courtyard while visitors can
relax in the shade.
The pavilion is parametrically designed in Grasshopper and Rhino, and
loads, sun and shade, and material use has been optimized.
Steel sheets of 2 mm have been laser cut and rolled at the factory and
then assembled by hand in situ.
After summer the pavilion will be standing at Chalmers University of
Technology during the autumn, after which it is possible to purchase it.
The pavilion is a collaboration between Röhsska museum of Design, Chalmers
University of Technology and Ribo-verken, and is the result of 33
Architecture students' work during one semester, in the master level class
'Material and Detail'. After selecting one initial design, 33 students
have worked to develop the design, and to turn the project into a pavilion
which is safe and constructable.
The purpose of the course is to explore digital fabrication and to turn it
into a real, built architectural project.
Words on the design:
When talking to the staff at Röhsska at our first site visit, it became
clear that the courtyard, even though at the time covered with snow, could
get extremely hot during summer days. Adding this fact to the briefs'
demand for seating and the size of the empty courtyard, we set out to
create a pavilion that provided shaded seating inside it as well as
creating shaded spaces around it to place existing chairs and tables. The
pavilion therefore creates a network of spaces with the existing furniture
that altogether manages to inhabit the large courtyard, like different
small islands in an archipelago, which together with the technique of
rolling the steel in to arc segments gave it its name.
Well inside the pavilion you can lie comfortably on the smooth surface
that uses the steels excellent possibility to stay cool wheEn shaded.
Inside you find yourself in a space, the pavilion, within a space, the
courtyard, that creates a small but secluded getaway from the hectic city
life of central Gothenburg that is just outside the courtyard. The
perforation in the ceiling spreads out an organic pattern resembling the
one you would see from a tree in the forest. Contrasting the smooth
inside, the outside of the pavilion lets the visitor study in detail how
the 133 pieces are joint together with 1535 joints with a total of 3640
bolts holding it together.
