Il comfort visivo e la gestione dell’illuminazione naturale in relazione al risparmio energetico diventano sempre più rilevanti per una progettazione innovativa degli edifici. Ad esempio, il nuovo protocollo LEED 4 riconosce crediti per le simulazioni di daylighting e conferma l’importanza degli aspetti progettuali per “collegare gli occupanti con lo spazio esterno, rinforzare i ritmi circadiani, ridurre i consumi di energia elettrica per l’illuminazione artificiale con l’introduzione della luce naturale negli spazi”. Senza strumenti software per la simulazione della luce non è possibile ottenere risultati di qualità. Radiance è un software validato, utilizzato sia a livello di ricerca che dai progettisti ed è tra i più accurati per la simulazione professionale della luce naturale e artificiale. Non ha limiti di complessità geometrica ed è adatto a essere integrato in altri software di calcolo e interfacce grafiche. Queste ultime facilitano le procedure di programmazione. Le principali e più versatili saranno oggetto del corso (DIVA4Rhino e Ladybug+ Honeybee, plug-in per Grasshopper e Rhinoceros 3D).
Il corso è rivolto a progettisti e ricercatori che vogliano acquisire strumenti pratici per la simulazione con Radiance al fine di mettere a punto e verificare le soluzioni più adatte alle proprie esigenze. Sono previste lezioni di teoria e pratica con esempi ed esercitazioni volte a coprire in modo dimostrativo ed interattivo i concetti trattati.
Le domande di iscrizione devono essere presentate entro il 16 novembre 2016.

ers and researchers, programmers and artists, professionals and academics who come together for 4 days of intense collaboration, development, and design.
The sg2012 Workshop will be organised around Clusters. Clusters are hubs of expertise. They comprise of people, knowledge, tools, materials and machines. The Clusters provide a focus for workshop participants working together within a common framework.
Clusters provide a forum for the exchange of ideas, processes and techniques and act as a catalyst for design resolution. The Workshop is made up of ten Clusters that respond in diverse ways to the sg2012 Challenge Material Intensities.
Applicants to the sg2012 Workshop will select their preferred cluster from the following:
Beyond Mechanics
Micro Synergetics
Composite Territories
Ceramics 2.0
Material Conflicts
Transgranular Perspiration
Reactive Acoustic Environments
Form Follows Flow
Bioresponsive Building Envelopes
Gridshell Digital Tectonics
More information about the Workshop and Clusters can be found here:
http://smartgeometry.org/index.php?option=com_content&view=article&id=116&Itemid=131
The application process will close on January 15th, 2012.
Full Fee $1500
Reduced Fee $750
Scholarship Fee $350
Fees include attendance to both the workshop and conference from March 19th-24th.
Reduced Fee and Scholarships are available only for Academics, Students and Young Practitioners, and are awarded during a competitive peer review process.
sg2012 takes place from 19-24 March 2012 at EMPAC (http://empac.rpi.edu/) and is hosted by Rensselaer Polytechnic Institute in Troy, upstate New York USA. The Workshop and Conference will be a gathering of the global community of innovators and pioneers in the fields of architecture, design and engineering.
The event will be in two parts: a four day Workshop 19-22 March, and a public conference beginning with Talkshop 23 March, followed by a Symposium 24 March. The event follows the format of the highly successful preceding events sg2010 Barcelona and sg2011 Copenhagen.
sg2012 Challenge Material Intensities
Simulation, Energy, Environment
Imagine the design space of architecture was no longer at the scale of rooms, walls and atria, but that of cells, grains and vapour droplets. Rather than the flow of people, services, or construction schedules, the focus becomes the flow of light, vapour, molecular vibrations and growth schedules: design from the inside out.
The sg2012 challenge, Material Intensities, is intended to dissolve our notion of the built environment as inert constructions enclosing physically sealed spaces. Spaces and boundaries are abundant with vibration, fluctuating intensities, shifting gradients and flows. The materials that define them are in a continual state of becoming: a dance of energy and information. Material potential is defined by multiple properties: acoustical, chemical, electrical, environmental, magnetic, manufacturing, mechanical, optical, radiological, sensorial, and thermal. The challenge for sg2012 Material Intensities is to consider material economy when creating environments, micro-climates and contexts congenial for social interaction, activities and organisation. This challenge calls for design innovation and dialogue between disciplines and responsibilities. sg2010 Working Prototypes strove to emancipate digital design from the hard drive by moving from the virtual to the actual in wrestling with the tangible world of physical fabrication. sg2011 Building the Invisible focused on informing digital design with real world data. sg2012 Material Intensities strives to energise our digital prototypes and infuse them with material behaviour. They have the potential to become rich simulations informed by the material dynamics, chemical composition, energy flows, force fields and environmental conditions that feed back into the design process.

akes the linear regression of the Schroeder integral over 30 dB worth of decay. Whether it is T-15 or T-30, they all seek to estimate the RT, which is always always the time it takes for sound to decay 60 decibels.
The website has benchmarks, for your reference. You can find them under the 'Pachyderm' drop down menu, under 'Benchmarks'.
Your model may well require millions of rays to be accurate. It sounds like a very large space. I'm sorry if that is an unpleasant answer. Sometimes it does help to have a computer with more cores to help with this. I have gotten up to 90% processor usage on a 12 core machine before.

hat differ in shapes, sizes and height the facade would be a mess. Some spaces need some light while other can't have any. I would like to have full freedom of creation inside the building, to make it as functional as possible. Thats why i decided the parametric "skin" solution would be best. Since the location has industrial past (factories made of brick) i decided that brick would give interesting result.
I tried creating the definition on my own but since i lack skill in GH i got some problems (especially multiplication of bricks and the diffrence between each "level" (half a brick on y axis) caused problems for me.
I post my simple sketch explaining the idea of definition i would like to create (sorry about quality):
1 - Brep - I would like to use 25x12x6cm (classic brick) but as well experiment with diffrent shapes - like the one on the right with hole inside - that would give more light. Thats why i think the best solution would be using brep for this definition.
2- Multiplication - biggest problem for me - I don't know how tall the wall would be, what will be the final shape of Brep (brick) and that's why i would like to manipulate this with sliders as well. All the walls are flat (maybe it would be easier to use surface?). As i managed to multiply the bricks easy way i don't know how to gain control over height of the wall - for example that it is 30 bricks high, but has each second row moved on x axis by the distance of 1/2 brick. I tried using Series but with no success. Could you help me with that please?
3 - Rotation - i would like to use image sampler for that so i can "paint" where i want more sun and where i dont need it at all (black and white). The rotation has to be limited to 180 degrees as well. Obviously i didn't get here yet, but i never used image sampler so if you could give me some advice how to use component and how to create such images i would be really grateful.
4 - More of a concept thing - since the connection angles differ from 90 degrees i will have to figure out how to connect the parts of the wall at sides ;).
I would like to ask you for help with the defintion, since i am totally stuck at step 2. I post what i came up with so far. Thank you for your time and help!
PS. I post an image that is pretty similar to one of options i would like to check for my building.

h, and using the BScale and BDistance are creating havoc somehow too. I've simplified first, and used the Kangaroo Frames component along with setting internal iterations, to make MeshMachine act like a normal component, along with releasing the FixC and FixV. The FixV didn't make any sense anyway. I've also set Pull to 0 to speed it up during testing, since much less calculation is involved to just let the meshes collapse, prevented from disappearing altogether by using a mere 15 iterations.
Also, your breps are open so that allows much more chaos and then collapse, though they did manage to close themselves too at times. Here is closed breps with a full 45 iterations:
So now that it's working, lets re-Fix the curves, and the problem arises that there is an extra seam line that is getting fixed too, running along the cylinder, stopping the mesh from pulling tight under tension wherever a vertex happens to be near that line:
So lets grab only the naked edge curves instead:
And what happens if we lose the end caps, now that we don't have an extra line skewing the result?:
There is no real curvature differences since it's not a curvy brep so the Adapt at full 1 setting has little to do. Now what does the BScale and BDist do? Nothing! Why? Your scale is out of whack, 99 mm high cylinders but only a falloff maximum of about 5, so let's make the falloff be 25 instead, but I must restore the end caps or the meshes collapse away for some reason and freezes Rhino for a minute or so the first time I try it:
It's a start.
If I intersect the cylinders, nothing changes, since they are being treated as separate runs. MeshMachine outputs a sequence of two outputs though, due to Frames being set to a bare minimum of 2 needed to get it to work, so I filter out the original run, which is just the unmodified initial mesh it creates.
The lesson so far is that closed meshes are much less prone to collapse and glitches leading to screw ups.
A Boolean union of the cylinders is when it gets funner, here show with and without the fixed curves that seem to define boundaries too where really there are just polysurface edges:

es has guided me in a - what I once thought - specific path within architecture, but recent discoveries (like the Grasshopper-community etc.) have learned me that the field of digital and parametric architecture is so-to-speak alive and kicking. This is also the main subject I would like to write my thesis about. It is however mainly the subject and defining its boundaries – what do I really want to explore and research? – which is the most difficult factor at this time.
A concrete idea is non-existant, and my current visions will probably be redirected when I have a first meeting with the promotors in February. Moreover there is the knowledge that it is impossible to make a thesis at the institute in Antwerp on no matter what subject in the world of digital architecture. Understandably too, it’s a small world and does not always result in realised projects, but in impressive imagery. At this moment however, I am thinking of two possible research fields to focus on.
In a first option the focus might lie on how digital design tools can be used to bring a certain aspect of interactivity to building facades. Such interactivity can occur both in the design phase and throughout the use of the building. The first scenario, in which the interactivity occurs when designing, I would focus on how the designer can shape a building’s outer perspective in function of environmental parameters: obstacles, elements that block sunlight from entering the building, visually important landmarks, etc. It should be noted however that focus will mostly lie on the design element, and less on the energy-efficiency and sustainability. Tools that will be researched would include Grasshopper, Rhino Scripting, Processing and ParaCloud.
A second possible approach could be categorized under both Swarm Intelligence and Generative Design and might study how the aforementioned digital techniques might be implemented in the new urbanism. We notably see more (innovative) interventions in which the design and planning is heavily influenced by movement patterns and morphogenetic parameters and functions. Based on the outcome of these scripted techniques, designers tend to work towards a proposal which answers a certain urbanistic issue.
All additional insights, guidelines, tips, comments are more than welcome in order to help me define the scope of my thesis subject. I must admit I am pretty new to this digital design world (it is not actively promoted at my home university, but it is promoted at the university where I am studying for one year now) and thus have limited experience at the time of writing.
Please also feel free to check out the blog post concerning this topic, which is a little more elaborate: http://nielswouters.be/thesis-digital-design-english/

mplex the models are. If we are running multi-room E+ studies, that will take far longer to calculate.
Rhino/Grasshopper = <1%
Generating Radiance .ill files = 88%
Processing .ill files into DA, etc. = ~2%
E+ = 10%
Parallelizing Grasshopper:
My first instinct is to avoid this problem by running GH on one computer only. Creating the batch files is very fast. The trick will be sending the radiance and E+ batch files to multiple computers. Perhaps a “round-robin” approach could send each iteration to another node on the network until all iterations are assigned. I have no idea how to do that but hope that it is something that can be executed within grasshopper, perhaps a custom code module. I think GH can set a directory for Radiance and E+ to save all final files to. We can set this to a local server location so all runs output to the same location. It will likely run slower than it would on the C:drive, but those losses are acceptable if we can get parallelization to work.
I’m concerned about post-processing of the Radiance/E+ runs. For starters, Honeybee calculates DA after it runs the .ill files. This doesn’t take very long, but it is a separate process that is not included in the original Radiance batch file. Any other data manipulation we intend to automatically run in GH will be left out of the batch file as well. Consolidating the results into a format that Design Explorer or Pollination can read also takes a bit of post-processing. So, it seems to me that we may want to split up the GH automation as follows:
Initiate
Parametrically generate geometry
Assign input values, material, etc.
Generate radiance/ E+ batch files for all iterations
Calculate
Calc separate runs of Radiance/E+ in parallel via network clusters. Each run will be a unique iteration.
Save all temp files to single server location on server
Post Processing
Run a GH script from a single computer. Translate .ill files or .idf files into custom metrics or graphics (DA, ASE, %shade down, net solar gain, etc.)
Collect final data in single location (excel document) to be read by Design Explorer or Pollination.
The above workflow avoids having to parallelize GH. The consequence is that we can’t parallelize any post-processing routines. This may be easier to implement in the short term, but long term we should try to parallelize everything.
Parallelizing EnergyPlus/Radiance:
I agree that the best way to enable large numbers of iterations is to set up multiple unique runs of radiance and E+ on separate computers. I don’t see the incentive to split individual runs between multiple processors because the modular nature of the iterative parametric models does this for us. Multiple unique runs will simplify the post-processing as well.
It seems that the advantages of optimizing matrix based calculations (3-5 phase methods) are most beneficial when iterations are run in series. Is it possible for multiple iterations running on different CPUs to reference the same matrices stored in a common location? Will that enable parallel computation to also benefit from reusing pre-calculated information?
Clustering computers and GPU based calculations:
Clustering unused computers seems like a natural next step for us. Our IT guru told me that we need come kind of software to make this happen, but that he didn’t know what that would be. Do you know what Penn State uses? You mentioned it is a text-only Linux based system. Can you please elaborate so I can explain to our IT department?
Accelerad is a very exciting development, especially for rpict and annual glare analysis. I’m concerned that the high quality GPU’s required might limit our ability to implement it on a large scale within our office. Does it still work well on standard GPU’s? The computer cluster method can tap into resources we already have, which is a big advantage. Our current workflow uses image-based calcs sparingly, because grid-based simulations gather the critical information much faster. The major exception is glare. Accelerad would enable luminance-based glare metrics, especially annual glare metrics, to be more feasible within fast-paced projects. All of that is a good thing.
So, both clusters and GPU-based calcs are great steps forward. Combining both methods would be amazing, especially if it is further optimized by the computational methods you are working on.
Moving forward, I think I need to explore if/how GH can send iterations across a cluster network of some kind and see what it will take to implement Accelerad. I assume some custom scripting will be necessary.…
