ybee_EnergyPlus Window Shade Generator" component.
3. SolveAdj component has the input to set BC for interior surfaces.
If you want to set them to adiabatic then you can use setToAdiabatic components.
4. For natural ventilation Chris has provided extensive answers including this one.
If the component doesn't work then you need to download the files manually from github and replace the userObjects with the old ones. You have to do it separately for Ladybug and Honeybee which can be painful. Is there anyway to change the firewall settings?

Grasshopper. So, I once made an attempt to bind ms sqlServer in order to get frozen definitions at some states, to avoid managing baked objects in Rhino and also be able to retain whole results without using the GH state manager that rebuilds everything.
But at that time GH's VB.Net component didn't properly read referenced dlls and I forgot it since then.
At first, I was surprised by Slingshot's extensive interface : I was still having in mind my own old project, a tool that would have acted at the Rhino's geometry object level, and auto creating the needed tables.
The bd would have consisted of a main table, owning the objects ID and name, and related tables containing the necessary information relative to the main objects.
For example, a Brep is made of so and so underlying objects, passed to respective tables, according to GH objects definition layout (just the way they are written in the xml schema).
Then, on a db, query an object by name, and retrieve the whole object or underlying objects (e.g. at the bounding curves level, or points level for a Brep).
With Slingshot, I made a few attempts to cheat GH with BLOB data fields, but no way to get a whole object. It seems that GH simply provides an object.toString ... and GH is definitely not conceived to produce persistence outside of Rhino. If I have some spare time, I will try to extract
About points and colors, I am now simply using a single field with CHAR(asLargeAsNeeded...), as GH parses String to every Point (or Vector or Color) entry of any component.
I do so because it need less to display on the canvas...
Whatever I wrote before, I really like your conception, as opened to relational interactions between ...whatever you need or dream of !
One last thing : GH can't open the definition file "Genome_DB_Template.gh" that I've downloaded from your site : http://slingshot-dev.wikidot.com/database-genome. I was expecting to learn a lot from your very smart stuff ! (I am running GH 08.00.13 and Slingshot 0.7.2.0)
Slingshot is running great, opened to any use...Thanks again.
Best,
Stan

stall with Visual Studio Express, which is something that I highly recommend doing.
As far as a basic guide, I think most of the beginners books that are out there are going to cover the topics that are going to be used within Rhino/GH fairly well. On one hand, the books out there are all pretty decent, but its more that programming with GH doesn't really require using all of the features of dot NET. As long as you get things about syntax, flow statements, data types, an introduction to OOP, and coverage of using collections, they you'll be fine in regards to programming in GH.
The one that I have here, which is useful but not a stand out, is Beginning VB.NET. I've liked Apress recently, so their book Beginning VB 2008 might be worth a look. I have the O'Reily book VBscript in a nutshell, which is leans more towards reference with a good introduction. Although I can't say with certainly, their VB 2005 in a nutshell book seams to be along the same lines.
Also, I've yet to find a book that is very relevant to Rhino/GH or doesn't have a bunch of stuff that winds up going largely unused in the context of Rhino/GH. Its not that those topics are useless (they might be if you choose to take your programming in a more "typical" direction), but within Rhino/GH they just don't get much face time. The topics that are useful will always require some translation as well, since the examples use some generic kind of issue to demonstrate the topic at hand.
Lastly, I've gotten more mileage out of books that are more specific than the general ones, so if there are some specific issue that you think you might want to explore you might want to see if there's a book out there that's more useful. Since I think OOP is a important concept to grasp to program well with the SDK, I'd take a look at Beginning Object Oriented Programming as its been a very useful book for me.…

r even a geometry.
We want to develop open source architecture, and be able to reuse easily open source elements of projects shared by the community.
We are interested to display the 3D files in the browser, thanks to connection with external services like http://beta.speckle.xyz or others though at the moment it is not yet available.
When I discovered the grasshoper forum, I liked the fact that people talk very openly about their modelling problems and share definition files...
But I think Bricks could be a complementary publication mode, to find in a glance an element with all its geometry and a link back to the forum post to join the discussion.
Indeed when I work as an architect, I have not always the time to browse a forum with all its discussions to find a suitable element for my project.
I've quickly reposted 2-3 forums posts to test it out.
I would love to have your feedbacks on this new way of publishing grasshoper definition files and more globally 3d reusable geometries.
Here you can see a single definition or the list of definitions that can be classified at the left thanks to custom categories.
If you create an account and upload a few definitions and 3d images and files, you could also tell us, what you think of this process.

Refinement component at first, possibly using MeshMachine instead which is slow but actually gives many fewer triangles and adaptive meshing for tight curves too. Neither are easy to adjust on a deadline!
Then you have to sneak up on workable settings, using only a few lines, or Grasshopper will freeze perhaps indefinitely for 200 lines with extreme settings, especially the CS (Cube Size) setting that can blow up into a huge number if your scale is big.
Cocoon gives lots of nearly flat split quad faces so I quadrangulated those for fun:
Or MeshMachine can refine the mesh to make it efficient:
Whereas the Cocoon Refine component will merely return an equally fine mesh with more equilateral triangles but no serious remeshing to rid so many tiny triangles where they are not needed? Actually, it does seem to remesh also:
David said he used some of Daniel's MeshMachine code in there.…
ey provide all the means to what I try to achieve.
What I need is to get a fast (as possible) evaluation of passive heat/solar gain from a certain facade. I know my building can cool to a certain degree (lets say 80 W/m2 - now lets forget other internal gains) and I want to be sure my facade is not letting excessive amounts of heat into the room/building. Normally I would make a full blown simulation to count my overheating hours and thereby evaluate my facade. To speed up the process, the idea is just to evaluate overheating hours in a faster way. So what I am thinking is that excessive amounts may estimated by counting high intensity irradiation patches in a critical sky-component or whatever such thing would be called that surpasses my sensible cooling load. My hope is that any facade visible to the sky-patches would very similar to the number of overheating hours if properly calibrated to a simulated model. However I have no idea right now, if this can be done.
Why do this? Speed, convenience, whole building thermal analyses.
@Chris and @Abraham The critical sky-component is made with LBs radiance component radiation and filtering the beam-components with highest effects from a yearly epw-file.
@Chris Conductive heat gains are also important especially if the facade is badly insulated, so the next step is to filter the outdoor temperature parallel with that critical sky-component and then do a static heat transfer analysis and combine that with the effect from direct sun influence. Again, no idea if it works.
Hope it makes sense. I a little embarrassed I drew you into this little experiment. This was not at all the point of the discussion. But now we are into it I like to know what you think. If it works its kinda neat, at least i think it is.

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.

n account of the position of the sun and weather cannot be expressed in terms of a single set of luminous intensity values (which is what IES files do).
With regards to your example files, I agree with Chris. The primary reason for the low illuminance levels is that the light bounces are getting lost in the tube. Have you checked with the manufacturer/distributor if the location of the IES file should be inside the tube and not flush with the ceiling? Physically modelling such tubes in lighting software like Radiance (which is what HB uses) or AGI32 is a fairly expensive proposition. This is one of the reasons why manufacturers provide photometric data for such devices (however simplistic that data might be).
The candelamultiplier increases or decreases the luminous intensity values. So it will have a direct impact on the calculation. The primary reason for having that input was to enable users to do some testing with different lamp types and environmental factors such as dirt depreciation. You need not change them for your simulation. Assuming that the IES file is inside the tube, in order to make this calculation work inside HB you'd have to crank up the calculation settings to a very high level (start with -ab 10 -ad 4096).
Finally, due to shortcomings in the annual simulation software (Daysim), IES files will not work directly work with annual calculations. However, there is a fairly easy workaround for that issue. In case you are planning to run annual calculations with IES files, please let us know here.
