Dragonfly : Modeling Urban Heat Island with the UWG
Hello, did it step by step I got this error: [11:40:45.212080 ERROR] [openstudio.workflow.OSWorkflow] Found error in state 'OpenStudioMeasures' with message: 'LoadError: cannot load such file -- tmpdir' Can you please help
Thanks¡¡ you´re doing a great job on this. I am trying to run a simulation for Mexico City, but I have tried all de epw files and none of them allows me in the Open Studio. I think I will have to revise/complete an epw file. Do you know a methodology to acomplish that?
I tried to make the depth of the wall by extruding the window. But the direction is different. What should I do when I want the direction to be all in or out?
Is there a method to reduce simulation time?
Great tutorial! How would one 'add' in an area of grass cover if there was a park nearby. Is it possible to reference in that geometry as grass cover?
GRACIAS!!!!
We'll get back to butterfly eventually (maybe in another year or two) but chances are that you'll see the current Butterfly transition directly into LBT with a little refactoring. Butterfly is already structured similarly to the other LBT plugins and so it should not require the manual reconnecting of components that the Legacy Updater requires.
Hi Chris, is there any way to use Butterfly with Rhino 8? I am trying to simulate the impact that a natural ventilation measure will have on a building's indoor temperatures. Seems like butterfly is the only way to do this, but I am getting errors even with the example file.
It is awesome!
Thanks for all this effort. And it's all freee ❤. Do you have any idea to upgrade butterfly too?
Great! Thanks Chris
Hi there Chris, Is there a way to start making floors from top to bottom instead of from bottom to top? Thanks!!
Hi, I made the DragonFly sample task using Ladybug Tools youtube videos (Urban Energy with Dragonfly). Step by step. The simulation does not work.
I would have a blender
Ok, so how do I get this thing onto InDesign
Super helpful
please provide rhino file.
how can i get dragon fly for free.they provide free version to students?
Thanks for explaining the nodes and their use. This helped in finishing my goals for multi goal optimization scenario in postgrad.
Gracias!!
Can I use this to automate the process of importing gbXML files and run the analysis??
Thank you for the tutorial series!
I believe this video should be before the "legend parameters" one.
Totally agree, they were wrong in the order.
Great tutorial. It would be good to have a final video on how to interpret the results of each analysis in more depth, although you discuss it somewhat in each video.
Is there some way we can check the view we create using the HB View component?
Good tutorial. Some notes/questions: 1. Can you provide the .3dm model used in this tutorial? 2. It would be useful if you go through building the script when it is so simple instead of just showing a premade script, similar to Chris' energy tutorial. It's sometimes hard to follow the steps as I have to look up the components which can be confusing. 3. It seems there is a mistake in the "solid approach", as you are inputting the skylights both as apertures and shades and not inputting the context geometry.
Is the .3dm Rhino file for this tutorial available for download?
how can we export data to excel please
Thank you for the tutorial, i followed the same steps but when i do @4 panel like you, this error occurs (1. Solution exception:index out of range: 1) can you please suggest me what i can do, it is URGENT
Hi. You should post your questions on the forum: discourse.ladybug.tools
Thank you very much
Thank you very much
Thank you for all that you do
Thanks so much for the Tools and helpful videos! Ive got one question here regarding addition of HVAC loads. I tried to add it after creating the HBRoom and then i applied 'HB Set Conditioned->HB All-Air HVAC->HB Model' but the analysis counldnt run. (it ran perfectly without these HVAC inputs) Should be added behind the 'program' in the beginning as well? Thanks in advance for your help!
Thank you so much for your installation video. How do I run the program after installation? Thank you so much.
Hi! Two questions from a noob here: Is it necessary to set up all materials to perform this analysis correctly? What's the correct way to display the percentage results via the legend? Thanks!
Hi! Can ladybug give hourly data? how do you manage the data in excel? I want to obtain the solar gains inside a building floor for cooling load calculation. Thanks in advance!
For the Spatial Daylight Autonomy (SDA), you mentioned that it is How much space gets at least 300 lux for at least 50 % of the year. I believe it should be for at least 50 % of occupied hours (those that are defined in the schedule you used).
Thanks.
@5:18 number slider, why rotate using LB. Wind Rose should not be rotated. does not give right indicator for the building design analysis. Instead, presenter should have used the real case building plan superimposed and explain the net effect of wind rose.
I am having issues understanding the number sliders for the analysis Period is their a tutorial on what each one does and examples of setting them?
Clearly organised, really informative and helpful
❤
Hello, thank you very much for this very useful series. I have a question regarding the peak cooling and heating days. I am a bit confused how the peak cooling load for the summer season appears to be on January 1st whereas January is considered a month of the heating season? is this a mistake in the component or am i missing something? (referring to minute 8:34 in the video)
The component just outputs one day and does not detail which day of the year it is, so the visualisation component just assumes it is first day of the first month (Jan 1).
Thanks for your tutorial, this is quite useful. I have a question. I input the same building height as you do (@4, 3:01 in the video). But the running failed. It explains that "story must have at least one Room 2D." Do you know how to fix this problem?
Amazing videos! This tool is so useful Getting two errors when running the "Model to OSM" any idea or pointers 1. ** Severe ** <root>[ZoneHVAC:IdealLoadsAirSystem][Room_8_9665b0d6 Ideal Loads Air System] - Missing required property 'zone_supply_air_node_name'. 1. Solution exception: ** Fatal ** Errors occurred on processing input file. Preceding condition(s) cause termination.
For anyone looking, those errors just mean the versions aren't synced
I downloaded the files for SingleFamily - and ran them to get a run time error - 1. Solution exception:remove_colinear_vertices_envelope() got an unexpected keyword argument 'delete_degenerate'
Good evening, thank you for this video, but I have an inquiry, I followed the steps of the video, but there is always a problem that it sends me an error message (Solution exception:Story must have at least one Room 2D) and I do not know how to solve this problem? if there is a solution for this error?
Hi, I met the same problem. Do you address it?
How change the total hours in a year to daily values?
Thank you for your videos, can you explain how to use the measure_ input ? also how an OS measure is merged with the geometry .
