d. If what you say is correct about the small difference between the global horizontal and direct/diffuse calculations in the MENEX model, than the discrepancy likely has more to do with the difference between the approximation of human geometry in the MENEX model (plane or cylinder) and the human geometry approximation in the SolarCal model (some coefficients derived from radiation studies of mannequins). I noticed some fairly large differences between using a suggested global horizontal method and a direct/diffuse method with the SolarCal model (differences on the order of 20%) but I imagine that this is because a mannequin human geometry is more sensitive to changes in solar orientation than a cylinder or plane. All of this is very good to know.
Yes, I guess this might be the case: the sensitivity of the SolarCal model to different parts of human body surfaces and surfaces areas.
Am I correct in understanding that you recently corrected the grey-body assumption about sky temperature in the Thermal Comfort Indices component with this commit? https://github.com/mostaphaRoudsari/ladybug/commit/a2a37b6dccc4e750...
The previous incoming long-wave radiation was derived by Ångström for clear sky conditions. The added correction "(1 + 0.22*((N/10)**2.75))" is a fractional cloudiness factor by Maykut and Church (I attached the publication below which mentions it).
So the emissivity coefficient of the (cloudy) sky is now:
epsilon_sky = (0.82 - 0.25*(10**(-0.094*0.75*e))) * (1 + 0.22*((N/10)**2.75))
I do not think that you could use the same value to calculate the sky temperature with Stefan-Boltzmann law, as the incoming long-wave radiation has been derived from the air temperature (2 meters above the ground), not the sky temperature. So by:
skyTemp = (La / [epsilon_sky * sigma])^0.25 - 273.15
One would get the air temperature from which La is derived, not skyTemp.The possible reason why SolCal Mean radiant temperature is currently getting similar values to Thermal Comfort Indices Mean radiant temperature could be that fact your epsilon_sky is almost equal to 1 (0.95), so it depends solely on La.I spoke with Dr. Blazejczyk, and got a publication on different sky temperature models. Apart from upper mentioned Swinbank, Berdahl-Martin, Melchor it has a lot more methods with mutual comparison of their resulting values. I attached it below.…
d react in length to the variation of their respective angle deviation from the sun.
For the moment I have established a way that depending on Bigger than/Smaller than X value, there is a dispatch of data to produce to types of panel lenghts. As you can see on the image.
But I would be interested to find the way to organize the list of all angles and classify them in groups like 5 packages of 20 degrees deviation. So, the panels deviated 16,3 and 27,9 degrees would go in the package of 15-35º, for example, and the 33,1 would go in the 35-45º...etc..
And the question would be to assign the different groups of angles, to given positions for the vectors that define the panel surfaces.
I am confused at how I should tackle this problem. Is it a question of dividing domains? Or creating sublists? But then, how can I assign the data to a set of positions? Dispatch only works with A/B..
And if so, how could I limit the positions of the vectors that define the surfaces, to a min and max length that would not overlap out of the base pattern?
These are huge questions, eh? But I'm sure that someone has tackled this problem before...
Looks like an accumulation of pretty standard problems,..but all together!
Thanks a million for any examples or hints on how this could work!

eps are represented by multiple surfaces so the discussed techniques are not fully workable.
the attached files include my test gh and a solid file to input. I have been able to map a suitable voronoi latticework onto the brep surface - but then I'm stuck. I cannot offset the curves on the brep and create a useable strut surface that way. I cannot intersect swept pipes with the brep surface to create surface patches that could then be joined.
I need some elegant ideas; I seem to be going down a rabbit hole at the moment where I am doing ever more complex workarounds for the grasshopper capabilities. (A case in point; the rail sweep is not working for me for closed 3D polylines, so I am having to cut them up and sweep and cap the segments. Ugh).
Example input brep
Curves on brep - but no simple offset / trim mechanism
Potential rail defining strut trim - but no way to do so...
Brep / rail intersect - but no way to turn this into a surface...

Meeting Agenda:
1) Discuss what the group would like to learn this term through our regular scheduled meetings. Topics include the priority and sequence of Grasshopper exercises we would like to explore during the winter term from http://www.digitaltoolbox.info/grasshopper_basic.html and Processing tutorials from the Processing Handbook I received from MIT.
2) Watch the Matt Storus Church Machine video and have a discussion about parametric and generative tools in design.
If you have a chance, please read the following article by Tim Love called Between Mission Statement and Parametric Model at:
http://places.designobserver.com/entry.html?entry=10757
3) Discuss a possible design build project over the following winter and spring terms using the skill set this group is developing. Conversation led by Chris Nielson (please see comments below for a brief backstory)
4) Discuss possible applied research and design work for the National Conference on the Beginning Design Student paper, Machine Craft and the Contemporary Designer: exploring parameters and variables through making physical artifacts. I wrote the attached abstract and submitted it for the conference the past fall and it was accepted. To continue with the research I need to assemble a team of students that will help explore the principles I set forth by making physical objects with the cnc router. In exchange for helping with the research I will show participants how to use the cnc router, how to author machine code and provide you with the cnc controller interface software necessary to simulate machine movements. Not to mention, your work will be sited in the research paper I present at the conference at UNC Charlotte in March. More tomorrow night, of course.
Thank you for your interest and I hope to see you there.
Sincerely,
Erik Hegre

All,
In response to Erik, who requested that I describe my intentions in a design-build project and to the article posted (definitely required reading for this group) I propose that we begin development of a project that spans the realm of "sustainable social" architecture and parametric design. The particulars of such a design do need to be made concrete, and it will be important to define the goals of such a project.
Therefore, I would suggest that this serve as a forum for the next few weeks for those interested in producing a built project. I agree with Nico that it may not be feasible to create the built piece, whatever it may be, this term; however we should have the groundwork and a plan in place by the end of the next 10 weeks.
Either way, I would ask that everyone who is interested to please provide as many concepts to this forum to begin a discussion. If you are indeed interested, please submit goals that this project could achieve (energy, socially, aesthetically, economically, related) and perhaps what you envision the project to physically be (shading device, public bench, water catchment, interactive thermal contraption, etc . . . )
I look forward to hearing your thoughts!
Cheers,
Christopher…

ears many bridges had been constructed and even more has collapsed or has been destroyed. Today Warsaw is connected by eight road bridges and two rail bridges, only few of them have a bike lanes. Modern cities are going through rapid changes. Hamburg has announced that in less than 20 years they are closing the center for cars, Copenhagen notes major incrementation in bike use, city bike system has been successfully introduced to many Polish cities. Warsaw bicycle net path is still very weak and probably the most urgent issue is to build a new bridge overpassing the Vistula River. This year Warsaw City Council decided to run an architectural competition for a new bridge. Architecture for Society of Knowledge and Architektura Informacyjna, Master's Programs of Architecture Faculty of Warsaw University of Technology, and Architektura Parametryczna, a digital design educational platform, invite for workshop: Outcome: The primary goal of workshops is to find the most optimal position for new bicycle bridge (or bridges) in Warsaw to enhance the global accessibility and Walkscore. During the workshop the participants will develop an interactive tool that will help to understand the accessibility changes by connecting Vistula shores with bicycle bridges. Program: Four days event will include coding part and learning how to apply digital tools into urban scale problems along with lectures of invited guests. This workshop is planned for intermediate user that understand and use Grasshopper. The workshop will be conducted in English. Tools: SOFTWARE Rhinoeros, Grasshopper, Silverye, Elk, Shortest Walk, Human, gHowl, Unity HARDWARE: Multimedia tool a multimedia tool designed by Jacek Markusiewicz for data representation and design in VR Tutors: Jacek Markusiewicz is an architect graduated from Warsaw University of Technology and the Master in Advanced Architecture at IaaC Barcelona.
