ger 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.

sg2012 take place at Rensselaer Polytechnic Institute, Troy, in upstate New York from 19-24 March 2012. 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.…
orward polygon modelling combined with a subdivision surface method to smooth the modelled polygon control cage (see this andthis).
The Weaver Bird plug-in has several methods for subdividing and smoothing a mesh including the probably best known method Catmull-Clark as well as laplacian smoothing.
Although Grasshopper is becoming better at handling mesh construction and modelling you might want to consider packages such as 3ds Max, Maya, Modo or Blender for doing the initial cage (they all have most of the standard tools one would except from a polygon modeller). For Rhino there is also the funky fusion between subdivision surfaces and NURBS called T-Splines (gave it a spin a few weeks back, has some pretty decent polygon modelling tools actually).…
roader than this. IFC (Industry Foundation Class) as an open BIM format permits users with the choice of other software they work with. From Grasshopper you can choice to use the model data in Digital Project, Archicad, Microstation, Tekla and beyond. http://buildingsmart-tech.org/implementation/implementations
But there is much scope for improvements in the implementation of model importing/exporting in all software. This is also why I decided to develop a Revit Addon (I can reuse 80 to 90% of my existing c# code) to import the data within this environment. But again this enabling workflows from all the software above plus Rhino/Grasshopper into Revit.
Certainly I think the work of the others is impressive and in areas I haven't really broached yet. But given demand for these aspects I will certainly be looking at it.
Look forward to hearing other thoughts and observations.

temperature.
I changed it and things are clearer, yet now I became intrigued by a discrepancy between what is reported by the "conditionOfPerson" and the "percentOfTimeComfortable" outputs. At first glance would seem that they are reporting the same thing in different manner, but they both provide different outcomes (See pic).
Why is that the case?
Shouldn´t the "conditionOfPerson" output had to incorporate the values within the threshold of 80 or 90% (in case that is not happening)?
Any comments?...
PD: The AdaptiveComfortChart doesn´t provide any output data. Not that I wan´t to rush any one out to fix it, but I just want to report it.
Thanks!,

s random reduced with the random reduce component.
Then the random reduced surfaces, is extruded in z direction with negative factor, The plane surface is also extruded in z direction with negative factor, then i used Trim solid, and had about 40 boxes cut in the xy plane with different hight.( hight is from the flowing surface)
The i open a new grasshopper file, and take brep container, and get one of the boxes cut in xy plane, but if i use isotrim on the brep faces or subdivede quad from lunchbox, the divide component show orginal extruded surface and not the smaller one i got after using Trim solid, on the extrusion.
is it clear or you need the file, and have anyone a answer
thank you

orders from bottom to top. There are three pre-set heights: 20,000 / 50,000 / 80,000 (or 20, 50, 80 meters, I'm working in mm).
So if the three cantilevering volumes would be numbered 0,1 and 2, then I'm looking for a way to let Grasshopper generate the following:
A = 20m-position
B = 50m-position
C = 80m-position
(A,B,C):
0,1,2
0,2,1
1,0,2
1,2,0
2,0,1
2,1,0
Attached is wat I have so far, I have only managed to make simple translations per geometry.

summer because of the relative humidity of outdoor air will be over 80%.
I want to set the schedule like this
1) cooling setpoint to be 27C degree and max humidity to be 50%.
2) when the outdoor air temperature is lower than 27C, open the windows and ventilation naturally.
3) Air conditioning and dehumidification are needed only when the occupancies are at home (almost at night) and Natural ventilation is not to be.
4) Accept the indoor air relative humidity to be almost 100% when dry bulb temperature is lower than 27C.
Now, I set the air conditioning schedule as cooling setpoint schedule, but there are no components to set a dehumidification setpoint schedule.
The dehumidifier keeps working all day whichever the windows are opening or not.
How can I stop the dehumidifier during the windows open?
thank you.…
ng (It's a bit similar to the Knapsack problem):
I have a Variable --> XandI Have fix numbers (can we call "pieces") 9,12,15,18
I'd like to reach the X, with the summing of these numbers and using the minimum pieces ,it can't be lower than X, but it can be higher, maximum with 3.After this it has to found the most optimal combination which mostly use the same pieces
E.G.
X=98
The wrong solution is like = 1pcs of 18 = 9pcs of 9
Sum of pieces are 10
OR
= 3pcs of 18 = 1pcs of 15 = 1pcs of 12 = 2pcs of 9
Sum of pieces are 7
The right solution in this case = 5pcs of 18 = 1pcs of 9
(5*18)+(1*9)=99 it's good beacuse it's over with maximum 3 and uses the minimum pieces
Then it sends to a list like18 : 5pcs15 : 0pcs12 : 0pcs9 : 1pcsCan somebody help me ? Or is it possible to make this ?
Thank you…
