teraction for its Correlations cycle, AA Athens Visiting School scales up its design intentions in order to investigate links among discrete individual architectural systems in its 2013 version, Recharged.
Recharged with interconnectivity on different levels, the theme of investigation will revolve around the design of semi-independent design prototypes acting together to form elaborate unified results. The driving force in Cipher City: Recharged is the synergistic effect behind complex form-making systems where interactive design patterns arise out of a multiplicity of relatively simple rules.
In collaboration with the National Technical University of Athens, Cipher City: Recharged will explore participatory design and active engagement modeling and will continue building novel prototypes upon horizontal planes.
As in 2012, the design agendas of AA Athens and AA Istanbul Visiting Schools will directly create feedback on one another, allowing participation in either one or both Programmes.

ly 26-27-28-29 (digital fabrication)
The third edition of digitalMed Workshop is structured as a design laboratory. Participants will learn the challenging process of producing ideas, projects and research analysis that are to be developed through specific software and concepts that emerge through the use of mapping, parametric design and digital fabrication.
The workshop will take place in the city of Salerno (Italy) and it will last 11 days structured into 3 intensive weekends: July 13-14-15 (mapping); July 19-20-21-22 (parametric design); July 26-27-28-29 (digital fabrication).
Goals and Objectives:
We aim to make clear the theoretical and technical knowledge in the approach to parametric and generative design and digital fabrication. (From collection and data management, to the manner in which these inform the geometries, to the fabrication of prototypes.)
Participants will also have the opportunity to practice the new knowledge gained in the design laboratory through project work.
Project Theme:
"Urban Field" Identify, study and analyze the system of public spaces in the urban area of the city of Salerno.
Connection, mutation, generation and evolution are the themes to be followed in project work.
Brief Description of Topics:
- Mapping. Our reality, in all its forms, has studied through concepts of the theory of Complex Systems. The techniques that will be used to study events and places of reality, will work for the management, manipulation and visualization of data and information. These will form the basis for project management and driven geometry, conducted during the second phase of the workshop.
- Parametric Design. Introduction to Rhino* and Grasshopper. Specifically, we will explain the concepts with which to work with the software of parametric design and how they function. Through these tools, we will arrive at the definition of systems of mathematical and / or geometrical relationships that are able to generate and govern patterns, shapes and objects that will inform the final design.
- Digital Fabrication. In this phase, participants of the workshop are organized into working groups. Participants have access to materials and conceptual apparatus that will take them directly to the fabrication of the geometries of the project, with the use of software CAD / CAM interface and the use of machines for the digital fabrication.
The DigitalMed workshop is organized by Nomad AREA (Academy of Research & Training in topics of Contemporary Architecture), in collaboration with the City of Salerno, the Order of Architects Province of Salerno and the National Institute of Architecture In / Arch - Campania.
Interested parties may download the Notice of Competition at the address www.digitalmedworkshop.com and fill the pre-registration no later than July 10th 2012.

r Material Science and Ligaproduction.
The exhibition started on May 12th and will be presented until August 19th 2012.
What is the meaning of »modular«? Essentially, everything in the world consists of a com- bination of elements, thus, of modules. As the basic building block of the elements, an atom forms the smallest unit in a structure’s totality. It is part of a whole, serving as a model for decoding and making comprehensible complex systems. In many disciplines, for instance in music, the sequence of smallest common units derives from an ordering prin- ciple, a rhythmic spacing, and from an aesthetic whose modular structure has both regular and irregular proportions.
In architecture, the module and modular construction have been governing principles for thousands of years. Primates use twigs as construction components for their dwellings, si- milar to the more familiar birds’ nests. During the course of biological and cultural evolution, refined methods of connecting components have been developed. Increasingly sophisticated construction techniques have evolved parallel to the tools, construction equipment and weapons available, as well as to the construction materials and support systems that were chanced upon or invented.
Ever since the earliest settlements thousands of years ago, the module has defined construction. Its dimensions, production and assembly have developed from preindustrial craft techniques to the construction of buildings, arising with the invention of the steam engine and leading into the Industrial Era. The first computer in the 1930s marked another technological leap. So what possibilities does the computer offer today’s architects for de- sign and construction?
While industrial manufacturing methods still require a critical amount of similar elements for mass production, the use of computers increasingly facilitates construction based on customized production of short-run elements with individual formats and complex geome- tries. At least that’s the theory. Computer-controlled machines and robots cut and stack structural components according to drawings – i.e. data sets – developed by designers and producers. Thanks to these technologies, architecture in the digital age is experiencing an evolution in construction and modules. The pioneers in this area are the projects developed at academic parametric design research units.
This exhibition features various examples from the development of digital technologies, presented in their historical context and categorized according to material: wood, stone, concrete, metal and synthetics. The »Housing Modules« excursion presents a selection of special urban planning systems as a series of space modules.
The historical modules each represent a paradigm shift in the evolution of an individual material. Since modules offer a tremendous wealth of opportunity, this section does not attempt to deliver the full picture: rather it intends to serve as an inspiration for further exploration.
In keeping with the Architectural Particles theme, the exhibition’s architecture consists of a modular system of tetrahedrons and octahedrons. The resulting crystalline shapes high- light the connection to nature while recalling modular construction systems from various architectural eras.…
oo culm and the web is mad of bamboo slats connected to the culms on either side of the attachment points. To make things clearer (extracted from the above paper):
The authors of the paper did a numerical beam-model in ANSYS to see if they could replicate their theoretical results, and it is fairly correct (some differences due to the non-linear behavior of the semi-ring joints that they use, they remain of an order of 5-10% difference in maximum deflection).
My problem is that I am not able to obtain the same deflection values that the authors did (11.4 mm for a total service load of 7.063 kN applied punctually on the upper chord where the truss elements meet, or even replicate the load/deflection curve). Using an orthotropic material, with the engineering constants taken from (ResearchGate - A bamboo Beam-Column Connection Capable to Transmit Moment), my model is too flexible and I get a maximum deflection of 24.28 mm. I tried other orthotropic mechanical characterizations from other sources (Kathry & Mishra, 2012, Finite element analysis of bamboo and joints using steel members under various loading conditions for design study and Chand , Shukla & Sharma, 2008, Analysis of Mechanical Behaviour of Bamboo (Dendrocalamus strictus) by Using FEM), to no avail.
Of course, the problem could be with the material properties I inputted but I am trying to contact the research team to see directly with them. In the meantime, I am looking to make sure the model itself is not flawed.
It also seems to me that gravity was not accounted for in the numerical of the paper, but it seemed to much of an oversight to be possible (still, the deflection curve of their paper goes through 0).
There are several points I am not quite sure about: after all I am still fairly new to Karamba3D and may still have some things to learn about the inner mechanics of the plugin.
The very first is: should I put eccentricities of the slat-elements of the truss in the definition of their cross-section (directly with the Cross Section box) or as an offset of the beam element (with the ModifyElem box)? I tried both approaches and they seem to yield similar results (max. deflection change by 0.65mm in my latest model).
Second is: is it good practice to subdivide the beam elements in more than one element (and connecting the pieces rigidly) in order to get better results? I imagine some meshing or subdivision is performed when the analysis is run but there is no way of visualizing it (that I found in any case). Subdividing the chord elements seems to give smoother deformation results (though I did not check stress I have to admit). My issue on this topic is that the subdivision of the slat-elements of the web is problematic. On the screenshot below, where the elements are divided in two, lets take the example of node 18. It seems to me that all elements of the diagonal element (28, 29, 34 & 35) are all rigidly connected to the node 18. 28 & 29 are not connected together, independently from 34 & 35. The added rigidity may not be a bad thing for my model, but it is not correct I think? Is there a way of solving the problem?

Thank you all in advance for any insight (even on the inner logics of Karamba)!

a machine that is light and very sturdy. I have taken my Macbook Pro all around the world, carry it with me every day, even dropped it a few times and its still totally fine. Its thin and light.
2) You get some actual support for your hardware even a few years down the line. My Macbook Pro is from 2012 and I can still walk in to any Apple Store and get help with it, which I have done many, many times in different places around the world - I never had to show a receipt or was charged any money for help. There is no PC/Laptop manufacturer in the world with anything close to that, because companies like Asus, Dell, etc. bring out dozens of new versions of laptops every year, so its much harder to service them after a few years.
3) This is the most important one, which usually people forget when they say that Macbooks are overpriced: Resale Value. If you have ever tried to sell an old PC/Laptop (I have a few times), you will know how little value they have even after just 2-3 years. Macbooks retain their value very well and even after 4 years you can still get 50% of your original price.
4) Of course you can install Windows on it and it runs perfectly. I have MacOS and Windows on it and both run absolutely fine. On the Windows side I have Rhino+GH, Maya and a few others. Having Windows is good, because some software still only runs on Windows (looking at you, 3DSMax!). Most other software also runs on MacOS. In the interest of sanity it is great to have an alternative to Windows for all the day to day stuff, like Mail, Calender, Photos, Presentations, etc. that just always works.
5) As for performance: Yes, Macbook Pros dont necessarily have the latest and greatest in graphics cards (the rest is on par with PC laptops), but unless you want to play games you will not need it. VRay RT can do GPU rendering, but you wont get great performance from a Notebook GPU anyways and it doesnt make sense to do rendering on a laptop (especially since you have a workstation). You could get one of the older Macbook Pro Retina Late 2013 or Mid 2014 models with the GTX750M by Nvidia, which will be usable to render using VRay RT, but of course not huge performance. Better to invest in a good used graphics card for your workstation like an Nvdia GTX980ti, which is the best value for money for GPU rendering right now (lots of used ones available).
So at least consider also getting a Macbook Pro. You can buy refurbished models (depending where you are) and they are like new, but a lot cheaper or even get an older one thats used. It will be a worthwile investment.
Take it from someone who has used dozens of PCs and Macs in my lifetime and have to do the IT support here at work (where we also use both).
I still have my Macbook Pro Retina from 2012 and its still running perfectly, super fast, and I can use Rhino and GH for huge files, do GPU Rendering with Octane Render and all sorts of other heavy computing stuff.
Hope that helps.…

t defined from the discussion of radiation exchange between urban surfaces and the sky in urban heat island research (See Oke's literature list below). It will be affected by the proportion of sky visible from a given calculation point on a surface (vertical or horizontal) as a result of the obstruction of urban geometry, but it is not entirely associated with the solid angle subtended by the visible sky patch/patches.
So, I think using "geometry way" to approximate Sky View Factor is not correct. Sky View Factor calculation shall be based on the first principle defining the concept: radiation exchange between urban surface and sky hemisphere:
(image extracted from Johnson, G. T., & Watson, 1984)
Therefore, I always refer to the following "theoretical" Sky View Factors calculated at the centre of an infinitely long street canyon with different Height-to-width ratios in Oke's original paper (1981) as the ultimate benchmark to validate different methods to calculate SVF:
So, I agree with Compagnon (2004) on the method he used to calculate SVF: a simple radiation (or illuminance) simulation using a uniform sky.
The following images are the results of the workflow I built in the procedural modeling software Houdini (using its python library) according to this principle by calling Radiance to do the simulation and calculation, and the SVF values calculated for different canyon H/W ratios (shown at the bottom of each image) are very close to the values shown in Oke's paper.
H/W=0.25, SVF=0.895
H/W=1, SVF=0.447
H/W=2, SVF=0.246
It seems that the Sky View Factor calculated from the viewAnalysis component in Ladybug is not aligned with Oke's result for a given H/W ration: (GH file attached)
According to the definition shown in this component, I assume the value calculated is the percentage of visible sky which is a geometric calculation (shooting evenly distributed rays from sensor point to the sky and calculate the ratio of rays not blocked by urban geometry?), i.e solid angle subtended by visible sky patches, and it is not aligned with the original radiation exchange definition of Sky View Factor.
I'd suggest to call this geometrically calculated ratio of visible sky "Sky Exposure Factor" which is "true" to its definition and way of calculation (see the paper on Sky Exposure Factor below) so as to avoid confusion with "The Sky View Factor based on radiation exchange" as discussed in urban climate literature.
Appreciate your comments and advice!
