We hope to see you there! **************************************************** Workshop 28th-31st March Shop Talk 1 April Symposium 2 April Reception 2 April These events follow the highly successful previous SG events in Barcelona 2010, San Francisco 2009, Munich 2008, New York 2007, Cambridge/London, UK 2006 and multiple preceding events. Click here for more info... This year's Challenge is entitled:BUILDING THE INVISIBLEInforming Digital Design with Real World Data THE PREMISEVast streams of data offer a rich resource for designers. By incorporating external information into our design processes the autonomy of the design is challenged. User data, energy calculations, embedded sensing, material and structural simulation, human behaviour and perception, particle flows and force fields allows design to be situated and responsive. From the simulation of megacities to the solid modelling of material systems, design has the potential to be informed by the real. Design sits not separate from is environment but inhabits an ecological system, open, dynamic and interdependent, diverse, partially self-organising, adaptive, and fragile. Across scale and within time we now have the chance to instil architecture with an immanent intelligence creating new relationships between the user, the built and its ecosphere.THE OPPORTUNITYSystems theorists suggest that data is only a raw material. It can be differentiated from information, knowledge and wisdom. Understanding is multi-levelled: understanding of relations, understanding of patterns, understanding of principles. As digital designers our challenge is in harnessing the power of computation to assist us in informing our design process. Computers help us collect, manage and analyse the environment and inform us about an abundance of data. Our challenge is to use these inputs in a meaningful way to help us make better informed design decisions.THE AIMSG 2011 explores how the incorporation of real world data challenges existing design thinking. The SG 2011 workshop aim is to create physical prototypes of design systems to be exhibited in the SG2011 exhibition. The SmartGeometry Group is a not-for-profit educational organization dedicated to the use of computational tools in architecture and engineering. SG brings professionals, academics, and industry together to explore the next generation of digital design. SG Workshops are non-platform specific, believing it is the methodology, not the tool, that matters. …; Added by Shane Burger at 11:23am on January 6, 2011

Comment on: Topic 'Thoughts on bouancy driven natural ventilation': looked at autodesk simulation cfd 2015 and was optimistic because it had an export plugin from revit, which i use anyway for material takeoffs and etc, but found that it did not take solar radiation into account. This was a downer because I have heard that solar radiation could effect indoor airflow - convection - as much as 50 percent at a time. Then I searched again and found that Hyperworks, a software by altair technology can be coupled with a radiation software. So I went through the trouble of obtaining an educational license of Hyperworks. However, though some email exchange I have found that the coupling is a one-way. The radiation analysis software was used, I think, for understanding the solar loading for a SOM project called church of light. The support guy said : "Unfortunately our coupling with Hyperworks is really a one way coupling. We can accept H coefficients from their software in RadTherm, but they will not read in our wall temps. That said, it still can be a useful coupling in the sense that you can run the analysis in Hyperworks, send H coefficients to RadTherm, and run the analysis to better understand radiation and conduction. Most importantly, that analysis can be done for longer transient analysis, but will require much less compute time and resources." Not only did I not understand what he means by the H coefficients, my wanting to get a CFD understanding coupled with solar radiation was again, unsatisfied. In the mean while I had to finish a presentation so I haven't had the time to try to get some result on the natural ventilation. I would probably need to look into how their solutions work before I can understand if their software would "do the job" Thank you for letting me know about your work on this. I downloaded the Honeybee_Set EP Natural Ventilation component and made sure that it is allowed, but it does not show up in grasshopper. You pointed out that "The component (and the corresponding equation) is mostly meant for cases where you have zones with windows that are NOT connected by an air wall (or a larger airflow network)." I wondered if you are suggesting it would be a code violation for zones to be connected by an air wall for fire safety reasons. It would be a violation I guess, like not putting an fiber insulation or some kind of smoke stop between Spandrel panels and the edge of a floor plate would be a code violation for a typical office building. There is a project by kevin daly architects where you can see a section drawing with what seems like a cfd analysis (could be an illustration) it was my initial visualization/simulation goals were for a facade design I am working on 1) an average air velocity across a zone at noon, for example, if a passive design strategy like this was used. for this I am guessing cfd is not entirely necessary. probably means that it could be used earlier in a design process, too. This would be more about user comfort. 2) at a later phase, like in detailing facade components, if airflow is indeed as expected for a zone that is connected to an air wall / chimney like feature (and to see if there is a proper mixing of air) 3) and a projection of energy savings, of course. After seeing a video of simulation cfd I was optimistic, but like I said sim cfd does not take account of solar loading. I think I would probably go ahead start with one zone with sim cfd first, try three zones stacked on top of each other, then try hyperworks and try to factor in solar radiation. For analyzing multiple zones on different levels, being able to add a chimney would be especially useful, I think. Having said that, I don't have a lot of experience of using honeybee except for the daylight component so it would take some time for me to understand the components. I hope some of the information here is useful for you. after all, both sim cfd and hyperworks are commercial softwares and somewhat different than the e plus project you are working on, I guess but still trying to address a similar problem. so.. in cased you missed it I was asking I downloaded the Honeybee_Set EP Natural Ventilation component and made sure that it is allowed and placed in the user object foler, but it does not show up in grasshopper. what could be the reason? …; Added by yj to Ladybug Tools at 9:32am on January 10, 2015

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.

Topic: NEW RELEASE OF LADYBUG AND HONEYBEE!: ion of both Ladybug and Honeybee. Notable among the new components are 51 new Honeybee components for setting up and running energy simulations and 15 new Ladybug components for running detailed comfort analyses. We are also happy to announce the start of comprehensive tutorial series on how to use the components and the first one on getting started with Ladybug can be found here: https://www.youtube.com/playlist?list=PLruLh1AdY-Sj_XGz3kzHUoWmpWDXNep1O A second one on how to use the new Ladybug comfort components can be found here: https://www.youtube.com/playlist?list=PLruLh1AdY-Sho45_D4BV1HKcIz7oVmZ8v Here is a short list highlighting some of the capabilities of this current Honeybee release: 1) Run EnergyPlus and OpenStudio Simulations - A couple of components to export your HBZones into IDF or OSM files and run energy simulations right from the grasshopper window! Also included are several components for adjusting the parameters of the simulations and requesting a wide range of possible outputs. 2) Assign EnergyPlus Constructions - A set of components that allow you to assign constructions from the OpenStudio library to your Honeybee objects. This also includes components for searching through the OpenStudio construction/material library and components to create your own constructions and materials. 3) Assign EnergyPlus Schedules and Loads - A set of components for assigning schedules and Loads from the Openstudio library to your Honeybee zones. This includes the ability to auto-assign these based on your program or to tweak individual values. You can even create your own schedules from a stream of 8760 values with the new “Create CSV Schedule” component. Lastly, there is a component for converting any E+ schedule to 8760 values, which you can then visualize with the standard Ladybug components 4) Assign HVAC Systems - A set of components for assigning some basic ASHRAE HVAC systems that can be run with the Export to OpenStudio component. You can even adjust the parameters of these systems right in Grasshopper. Note: The ASHRAE systems are only available for OpenStudio and can’t be used with Honeybee’s EnergyPlus component. Also, only ideal air, VAV and PTHP systems are currently available but more will be on their way soon! 5) Import And Visualize EnergyPlus Results - A set of components to import numerical EnergyPlus simulation results back into grasshopper such that they can be visualized with any of the standard Ladybug components (ie. the 3D chart or Psychrometric chart). Importers are made for zone-level results as well as surface results and surfaces results can be easily separated based on surface type. This also means that E+ results can be analyzed with the new Ladybug comfort calculator components and used in shade or natural ventilation studies. Lastly, there are a set of components for coloring zone/surface geometry with EnergyPlus results and for coloring the shades around zones with shade desirability. 6) Increased Radiance and Daysim Capabilities - Several updates have also been made to the existing Radiance and Daysim components including parallel Radiance Image-based analysis. 7) Visualize HBObject Attributes - A few components have been added to assist with setting up honeybee objects and ensuing the the correct properties have been assigned. These include components to separate surfaces based on boundary condition and components to label surfaces and zones with virtually any of their EnergyPlus or Radiance attributes. 8) WIP Grizzly Bear gbxml Exporter - Lastly, the release includes an WIP version of the Grizzly Bear gbXML exporter, which will continue to be developed over the next few months. And here’s a list of the new Ladybug capabilities: 1) Comfort Models - Three comfort models that have been translated to python for your use in GH: PMV, Adaptive, and Outdoor (UTCI). Each of these models has a “Comfort Calculator” component for which you can input parameters like temperature and wind speed to get out comfort metrics. These can be used in conjunction with EPW data or EnergyPlus results to calculate comfort for every hour of the year. 2) Ladybug Psychrometric Chart - A new interactive psychrometric chart that was made possible thanks to the releasing of the Berkely Center for the Built Environment Comfort Tool Code (https://github.com/CenterForTheBuiltEnvironment/comfort-tool). The new psychrometric chart allows you to move the comfort polygon around based on PMV comfort metrics, plot EPW or EnergyPlus results on the psych chart, and see how many hours are made comfortable in each case. The component also allows you to plot polygons representing passive building strategies (like internal heat gain or evaporative cooling), which will adjust dynamically with the comfort polygon and are based on the strategies included in Climate Consultant. 3) Solar Adjusted MRT and Outdoor Shade Evaluator - A component has been added to allow you to account for shortwave solar radiation in comfort studies by adjusting Mean Radiant Temperature. This adjusted MRT can then be factored into outdoor comfort studies and used with an new Ladybug Comfort Shade Benefit Evaluator to design outdoor shades and awnings. 4) Wind Speed - Two new components for visualizing wind profile curves and calculating wind speed at particular heights. These allow users to translate EPW wind speed from the meteorological station to the terrain type and height above ground for their site. They will also help inform the CFD simulations that will be coming in later releases. 5) Sky Color Visualizer - A component has been added that allows you to visualize a clear sky for any hour of the year in order to get a sense of the sky qualities and understand light conditions in periods before or after sunset. Ready to Start? Here is what you will need to do: Download Honeybee and Ladybug from the same link here. Make sure that you remove any old version of Ladybug and Honeybee if you have one, as mentioned on the Ladybug group page. You will also need to install RADIANCE, DAYSIM and ENERGYPLUS on your system. We already sent a video about how to get RADIANCE and Daysim installed (link). You can download EnergyPlus 8.1 for Windows from the DOE website (http://apps1.eere.energy.gov/buildings/energyplus/?utm_source=EnergyPlus&utm_medium=redirect&utm_campaign=EnergyPlus%2Bredirect%2B1). “EnergyPlus is a whole building energy simulation program that engineers, architects, and researchers use to model energy and water use in buildings.” “OpenStudio is a cross-platform (Windows, Mac, and Linux) collection of software tools to support whole building energy modeling using EnergyPlus and advanced daylight analysis using Radiance.” Make sure that you install ENERGYPLUS in a folder with no spaces in the file path (e.g. “C:\Program Files” has a space between “Program” and “Files”). A good option for each is C:\EnergyPlusV8-1-0, which is usually the default locations when you run the downloaded installer. New Example Files! We have put together a large number of new updated example files and you should use these to get yourself started. You can download them from the link on the group page. New Developers: Since the last release, we have had several new members join the Ladybug + Honeybee developer team: Chien Si Harriman - Chien Si has contributed a large amount of code and new components in the OpenStudio workflow including components to add ASHRAE HVAC systems into your energy models and adjust their parameters. He is also the author of the Grizzly Bear gbxml exporter and will be continuing work on this in the following months. Trygve Wastvedt - Trygve has contributed a core set of functions that were used to make the new Ladybug Colored Sky Visualizer and have also helped sync the Ladybug Sunpath to give sun positions for the current year of 2014 Abraham Yezioro - Abraham has contributed an awesome new bioclimatic chart for comfort analyses, which, despite its presence in the WIP tab, is nearly complete! Djordje Spasic - Djordje has contributed a number of core functions that were used to make the new Ladybug Wind Speed Calculator and Wind Profile Visualizer components and will be assisting with workflows to process CFD results in the future. He also has some more outdoor comfort metrics in the works. Andrew Heumann - Andrew contributed an endlessly useful list item selector, which can adjust based on the input list, and has multiple applications throughout Ladybug and Honeybee. One of the best is for selecting zone-level programs after selecting an overall building program. Alex Jacobson - Alex also assisted with the coding of the wind speed components. And, as always, a special thanks goes to all of our awesome users who tested the new components through their several iterations. Special thanks goes to Daniel, Michal, Francisco, and Agus for their continuous support. Thanks again for all the support, great suggestions and comments. We really cannot thank you enough. Enjoy!, Ladybug + Honeybee Development Team PS: If you want to be updated about the news about Ladybug and Honeybee like Ladybug’s Facebook page (https://www.facebook.com/LadyBugforGrasshopper) or follow ladybug’s twitter account (@ladybug_tool). …; Added by Chris Mackey to Ladybug Tools at 11:49pm on September 14, 2014

Comment on: Topic 'FLICKR API and Grasshopper': doing this with the current tools or a bit of scripting since the Flickr API allows you to make requests in a REST format, but utilizing the Flickr.net API library makes it much simpler. First and foremost, you need a Flickr API key...do you have one of those? A great way to get to know the Flickr API is with the API Explorer. Here is a link to the page for the flickr.photos.search method explorer: http://www.flickr.com/services/api/explore/flickr.photos.search The cool thing about this page is that it generates the REST Http call towards the bottom. So, here is what I did: 1. Grab the coordinates of the bounding box per Flickr API request: bbox (Optional) A comma-delimited list of 4 values defining the Bounding Box of the area that will be searched. The 4 values represent the bottom-left corner of the box and the top-right corner, minimum_longitude, minimum_latitude, maximum_longitude, maximum_latitude. Longitude has a range of -180 to 180 , latitude of -90 to 90. Defaults to -180, -90, 180, 90 if not specified. Unlike standard photo queries, geo (or bounding box) queries will only return 250 results per page. Geo queries require some sort of limiting agent in order to prevent the database from crying. This is basically like the check against "parameterless searches" for queries without a geo component. A tag, for instance, is considered a limiting agent as are user defined min_date_taken and min_date_upload parameters — If no limiting factor is passed we return only photos added in the last 12 hours (though we may extend the limit in the future). So, I went to Google Earth, picked a city (London, UK) and dropped two pins: This gave me two locations, which I can put into the Explorer Page next to the bbox option. Here is what I put for these two points: -0.155941,51.496768,-0.116783,51.511431 2. Check has_geo 3. In extras, type in geo 4. Make the call! You will see a list of responses in an XML format, these responses will be from the first page. Geolocated photos are limited to 250 / page, so you will have to grab them page by page. If you want to add more options (minimum upload date, maximum upload date, etc) you can do this as well) The best is at the bottom, you get the full http call for this: http://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=ffd44f601393a46e86aa3a5f8a013360&bbox=-0.155941%2C51.496768%2C-0.116783%2C51.511431&has_geo=&extras=geo&format=rest&api_sig=b42330e5d1523bd5fe60c2ad43acde99 Notice this call has some other api key, you should eventually replace this with your own. You could copy and paste this into a browser and you will get the results with the latitude and longitude: So this is really what you need to know to do this through GH. Since gHowl has an XML parser component that can access files on the web, you should be able to use the same http call into this component. Eventually, we get a response, and we need to grab the lat and lon data. With gHowl we can map these to xyz coordinates, and generate the heatmap...this is just a linear mapping: Attached are both the Rhino file and the Grasshopper file, as well as the image underlay. I am working on a series of components that makes this more straightforward, but for now, this should get you started. …; Added by Luis Fraguada to gHowl at 3:45am on March 1, 2013

Topic: ARCHITECTURE LIVE (EMPA - electronic music parametric architecture): and export the geometry out to VVVV to render it LIVE! RawRRRR. In this case, a digital audio workstation Ableton Live, a leading industrial standard in contemporary music production. the good news is that VVVV and ableton live lite is both free. https://www.ableton.com/en/products/live-lite/ i am not trying to use ipad as a controller for grasshoppper. I wanted to work with a timeline (similar to MAYA or Ableton or any other DAW(digital audio workstation)) inside grasshopper in an intuitive way. Currently there is no way of SEQUENCING your definition the way you want to see that i know of. no more combersome export import workflows... i dont need hyperrealistic renderings most of the time. so much time invested in googling the right way to import, export ... mesh settings...this workflow works for some, for some not ...that workflow works if ... and still you cannot render it live nor change sequence of instruction WHILE THE VIDEO is played. and I think no one wants to present rhinoceros viewport. BUT vvvv veiwport is different. it is used for VJing and many custom audio visual installation for events, done professionally. you can see an example of how sound and visuals come together from this post, using only VVVV and ableton. http://vvvv.org/documentation/meso-amstel-pulse I propose a NEW method. make a definition, wire it to ableton, draw in some midi notes, and see it thru VVVV LIVE while you sequence the animation the WAY YOU WANT TO BE SEEN DURING YOUR PRESENTATION FROM THE BEGINNING, make a whole set of sequences in ableton, go back change some notes in ableton and the whole sequence will change RIGHT INFRONT of you. yes, you can just add some sound anywhere in the process. or take the sound waves (sqaure, saw, whateve) or take the audio and influence geometric parameters using custom patches via vvvv. I cannot even begin to tell you how sophisticated digital audio sound design technology got last ten year.. this is just one example which isn't even that advanced in todays standard in sound design ( and the famous producers would say its not about the tools at all.) http://www.youtube.com/watch?v=Iwz32bEgV8o I just want to point out that grasshopper shares the same interface with VVVV (1998) and maxforlive, a plug in inside ableton. audio mulch is yet another one that shares this interface of plugging components to each other and allows users to create their own sound instruments. vvvv is built based on vb, i believe. so current wish list is ... 1) grasshopper recieves a sequence of commands from ableton DONE thanks to sebastian's OSCglue vvvv patch and this one http://vvvv.org/contribution/vvvv-and-grasshopper-demo-with-ghowl-udp after this is done, its a matter of trimming and splitting the incoming string. 2) translate numeric oscillation from ableton to change GH values video below shows what the controll interface of both values (numbers) and the midi notes look like. https://vimeo.com/19743303 3) midi note in = toggle GH component (this one could be tricky) for this... i am thinking it would be great if ...it is possible to make "midi learn" function in grasshopper where one can DROP IN A COMPONENT LIKE GALAPAGOS OR TIMER and assign the component to a signal in, in this case a midi note. there are total 128 midi notes (http://www.midimountain.com/midi/midi_note_numbers.html) and this is only for one channel. there are infinite channels in ableton. I usually use 16. I have already figured out a way to send string into grasshopper from ableton live. but problem is, how for grasshopper to listen, not just take it in, and interpret midi and cc value changes ( usually runs from 0 to 128) and perform certain actions. Basically what I am trying to achieve is this : some time passes then a parameter is set to change from value 0 to 50, for example. then some time passes again, then another parameter becomes "previewed", then baked. I have seen some examples of hoopsnake but I couldn't tell that you can really control the values in a clear x and y graph where x is time and y is the value. but this woud be considered a basic feature of modulation and automation in music production. NVM, its been DONE by Mr Heumann. https://vimeo.com/39730831 4) send points, lines, surfaces and meshes back out to VVVV 5) render it using VVVV and play with enormous collection of components in VVVV..its been around since 1998 for the sake of awesomeness. this kind of a digital operation-hardware connection is usually whats done in digital music production solutions. I did look into midi controller - grasshopper work, and I know its been done, but that has obvious limitations of not being precise. and it only takes 0 o 128. I am thinking that midi can be useful for this because then I can program very precise and complex sequence with ease from music production software like ableton live. This is an ongoing design research for a performative exhibition due in Bochum, Germany, this January. I will post definition if I get somewhere. A good place to start for me is the nesting sliders by Monique . http://www.grasshopper3d.com/forum/topics/nesting-sliders …; Added by yj at 1:33pm on November 14, 2012

Topic: What are the icons on a component's input/output parameter?: ers can be applied from the right click Context Menu of either a component's input or output parameters. With the exception of <Principal> and <Degrees> they work exactly like their corresponding Grasshopper Component. When a I/O Modifier is applied to a parameter a visual Tag (icon) is displayed. If you hover over a Tag a tool tip will be displayed showing what it is and what it does. The full list of these Tags: 1) Principal An input with the Principal Icon is designated the principal input of a component for the purposes of path assignment. For example: 2) Reverse The Reverse I/O Modifier will reverse the order of a list (or lists in a multiple path structure) 3) Flatten The Flatten I/O Modifier will reduce a multi-path tree down to a single list on the {0} path 4) Graft The Graft I/O Modifier will create a new branch for each individual item in a list (or lists) 5) Simplify The Simplify I/O Modifier will remove the overlap shared amongst all branches. [Note that a single branch does not share any overlap with anything else.] 6) Degrees The Degrees Input Modifier indicates that the numbers received are actually measured in Degrees rather than Radians. Think of it more like a preference setting for each angle input on a Grasshopper Component that state you prefer to work in Degrees. There is no Output option as this is only available on Angle Inputs. 7) Expression The Expression I/O Modifier allows you change the input value by evaluating an expression such as -x/2 which will have the input and make it negative. If you hover over the Tag a tool tip will be displayed with the expression. Since the release of GH version 0.9.0068 all I/O Expression Modifiers use "x" instead of the nickname of the parameter. 8) Reparameterize The Reparameterize I/O Modifier will only work on lines, curves and surfaces forcing the domains of all geometry to the [0.0 to 1.0] range. 9) Invert The Invert Input Modifier works in a similar way to a Not Gate in Boolean Logic negating the input. A good example of when to use this is on [Cull Pattern] where you wish to invert the logic to get the opposite results. There is no Output option as this is only available on Boolean Inputs. …; Added by Danny Boyes at 11:41am on March 10, 2014
