Blog Post: Masterstudio "Inhabitable Skin" at Institut of Buildings and Energy: Added by Igor Mitrić Lavovski at 4:12pm on September 30, 2016

Topic: Update + Happy Yalda!: t. So here we go! 1. Honeybee is brown and not yellow [stupid!]... As you probably remember Honeybee logo was initially yellow because of my ignorance about Honeybees. With the help of our Honeybee expert, Michalina, now the color is corrected. I promised her to update everyone about this. Below are photos of her working on the honeybee logo and the results of her study. If you think I'm exaggerating by calling her a honeybee expert you better watch this video: Thank you Michalina for the great work! :). I corrected the colors. No yellow anymore. The only yellow arrows represent sun rays and not the honeybee! 2. Yellow or brown, W[here]TH Honeybee is? I know. It has been a long time after I posted the initial video and it is not fun at all to wait for a long time. Here is the good news. If you are following the Facebook page you probably now that the Daylighting components are almost ready. Couple of friends from Grasshopper community and RADIANCE community has been helping me with testing/debugging the components. I still think/hope to release the daylighting components at some point in January before Ladybug gets one year old. There have been multiple changes. I finally feel that the current version of Honeybee is simple enough for non-expert users to start running initial studies and flexible enough for advanced users to run advanced studies. I will post a video soon and walk you through different components. I think I still need more time to modify the energy simulation components so they are not going to be part of the next release. Unfortunately, there are so many ways to set up and run a wrong energy simulation and I really don’t want to add one new GIGO app to the world of simulation. We already have enough of that. Moreover I’m still not quite happy with the workflow. Please bear with me for few more months and then we can all celebrate! I recently tested the idea of connecting Grasshopper to OpenStudio by using OpenStudio API successfully. If nothing else, I really want to release the EnergyPlus components so I can concentrate on Grasshopper > OpenStudio development which I personally think is the best approach. 3. What about wind analysis? I have been asked multiple times that if Ladybug will have a component for wind study. The short answer is YES! I have been working with EFRI-PULSE project during the last year to develop a free and open source web-based CFD simulation platform for outdoor analysis. We had a very good progress so far and our rockstar Stefan recently presented the results of the work at the American Physical Society’s 66th annual DFD meeting and the results looks pretty convincing in comparison to measured data. Here is an image from the presentation. All the credits go to Stefan Gracik and EFRI-PULSE project. The project will go live at some point next year and after that I will release the Butterfly which will let you prepare the model for the CFD simulation and send it to EFRI-PULSE project. I haven’t tried to run the simulations locally yet but I’m considering that as a further development. Here is how the component and the logo looks like right now. 4. Teaching resources It has been almost 11 months from the first public release of Ladybug. I know that I didn't do a good job in providing enough tutorials/teaching materials and I know that I won’t be able to put something comprehensive together soon. Fortunately, ladybug has been flying in multiple schools during the last year. Several design, engineering and consultant firms are using it and it has been thought in several workshops. As I checked with multiple of you, almost everyone told me that they will be happy to share their teaching materials; hence I started the teaching resources page. Please share your materials on the page. They can be in any format and any language. Thanks in advance! I hope you enjoyed/are enjoying/will enjoy the longest night of the year. Happy Yalda!

Topic: Angophora tree trunk. Generate 3~5 "random" points around the perimeter of a shape with a minimum distance apart; each point a small, random distance away from original shape's perimeter.: But not just any gum tree. The angophora, no less: Why? Because I like nature, that's why. Every time I see new designs –especially architectural designs– it worries me that the natural environment is being taken over. Not just that, but even the new materials used in all product designs has to come from nature as well [read: mines]. So. People are forgetting that we still need trees and I believe that if someone sees a beautiful [read: established] tree in their architectural plans, they are going to be much more likely to build around it and not cut it down. That alone would no doubt increase the value of the house. My thinking is that current tree models suck. They look unnatural and I think I know why. They're not random or organic enough. They're not detailed enough. That's basically my 'rationale' for this project. Just look at how different all of these tree trunks are! So I am not being paid for this project. It's a personal project of mine. I'm just worried about the trunk shape for now — I'll worry about all the leaves... when I get to that. I am a grasshopper beginner. Please keep that in mind. I am also fairly hopeless at traditional programming, but I find the visual approach of grasshopper much easier to grasp. So unfortunately I have gotten stuck and need some help, even just a clue, as to how to proceed. That said, here is my current progress: About a year ago, I started modelling with straight trunks using pipe sections, to see if I could get a very basic "tree" shape. And to see if I could join the segments together. Yes it works but it looks hopeless as you can imagine. Then I stopped for a long while. Now I'm back at it, hoping to improve a lot more. I have already made one basic vertical nurbs curve with tangents at either end as the main "trunk". I tried creating two ellipses at each end of the main trunk/curve and lofting between them but it omitted the main curve/rail. So it ended up being an elliptical trunk with straight sides which of course still didn't look right. Then I divided the first main curve up into a number of segments. I think that is a better approach. I have taken the parameters of the curve at each segment (probably the tangent, but I am unsure what the exact parameter is) and used that to form a basic angled plane at each segment/division. I have been able to draw ellipses at each segment and rotate them onto the plane. I was going to loft it together later on. A Curved loft with elliptical cross-sections looks much better than straight a pipe does, but still looks too unnatural. I quickly realised that tree trunks are not elliptical, but rather, shaped more like 'kidneys'. The next step was to create >3 points on each of those planes (spaced fairly evenly around the ellipse so as not to create a really funky/unwanted shape). Maybe it would be better to model with a triangle or other polygon instead of an ellipse. I haven't got that far yet... because here is where I am getting stuck. I managed to find a way of getting three roughly 'triangular' points along each that ellipse. I also managed to create three nurbs cuves in the Z direction which intersected those three points, a bit like three seams down the side of the tree trunk, but couldn't figure out how to loft it all together. I think it was the wrong approach anyway... I'd rather try to create a bunch of nurbs curves at each of the XY planes so as to get more control of the shape. What I am trying to do now is create three roughly triangular-spaced points on a basic ellipse through which I can then draw a simple nurbs curve (think like a cross section of the trunk). I would then like to add some XY-only randomness to the positions of those points. Not Z randomness, otherwise the trunk is going to get messed/kinked up. That's probably very important. Then I would like to loft those nurbs curvs at each XY plane together forming the basic tree trunk, which also tapers based on some other variable (a non-linear factor, not simply distance from ground plane, perhaps something else?). I have attached the GH file. I am also open to suggestions if you have a better way of solving a problem. I would like to retain control over a lot of factor such as number of branches, spacing, average branch length, etc. My main contrsaints are that the entire thing has to be somewhat random and non-linear. …; Added by leslie dean brown at 12:13am on December 27, 2016

Topic: Ladybug Solar Water Heating components released !: option, after downloading check if .ghuser files are blocked (right click -> "Properties" and select "Unblock"). Then paste them in File->Special Folders->User Object Folder. You can download the example files from here. They act in similar way, Ladybug Photovoltaics components do: we pick a surface, and get an answer to a question: "How much thermal energy, for a certain number of persons can my roof, building facade... generate if I would populate them with Solar Water Heating collectors"? This information can then be used to cover domestic hot water, space heating or space cooling loads: Components enable setting specific details of the system, or using simplified ones. They cover analysis of domestic hot water load, final performance of the SWH system, its embodied energy, energy value, consumption, emissions... And finding optimal system and storage size. By Dr. Chengchu Yan and Djordje Spasic, with invaluable support of Dr. Willian Beckman, Dr. Jason M. Keith, Jeff Maguire, Nicolas DiOrio, Niraj Palsule, Sargon George Ishaya and Craig Christensen.

Comment on: Topic 'Writing a 3dm File using Visual Studio C#': then passed to the file3dm.Write() Method when it's used? Turns out it will work in the Visual Studio IDE perfectly well like this, Now I'm just sorting out the best way to create a surface.

Comment on: Topic 'Réseau sur surface': peuvent se diviser une surface avec ne importe quel motif imaginable. 3. Ici, je fournir un moyen de le faire via Lunchbox ... cela fonctionne mais il est fixe et donc nous avons besoin de jouer avec des arbres de données afin de créer le motif approprié par cas. 4. L'autre composante est un joint C # qui fait beaucoup de choses autres que de diviser ne importe quelle collection de points avec de nombreux modèles (voir le modèle ANDRE que je ai fait pour vous). 5. Vous devez décomposer une polysurface en morceaux afin de travailler sur les subdivisions. 6. Je donne une autre définition ainsi que pourrait agir comme un tutoriel sur la façon de traiter des ensembles de points via des composants de GH standards et des méthodes classiques.
