Sunhour analysis in Rhino3d Grasshopper and Ladybug | Tutorial 005
Вставка
- Опубліковано 26 сер 2024
- This tutorial shows how to reverse engineer a script to study the sun hours on your model. Again based on real location coordinates. Test the sun hours for a day, month or up to a year. This tool is ideal to get a better understanding of your planning area and helps in zoning plans, outdoor comfort, planting selection and more. Also learn how to change the output resolution to fit the size of your scheme.

Very nice video. I would like to see how to calculate heating gains in spaces. Can You do that?
Hey Kackad95, yes the tutorial 6 - Part1 and 2 Radiation Analysis is measuring the heatgain in kWh per m2. For PV pannel estimation for example.

very insightful!
Glad you think so!
And one more question - Can we and how we can see how greenery affects external thermal comfort here in Ladybug? Can we add some trees or something like grass here and make an experiment? Thanks a lot. You are great!
Its possible with Ladybug but only to a certain extent..
However Honeybee has more capability in that direction. I would start with the basics

what ladybug version is this? i dont seem to have some of the tools u showed in the video
This is the legacy version. Quite an old video...
How can I find sunlight hour analysis? I use Direct sun hour,but it hasn't baketl.
Just right click onto the heat map tool and choose bake.
hello, great video, i am just having a problem with a fact that when i run this analysis the colours on the geometry are tinted as if there was a object below it, even though i hid everything. do you have any idea why that could be the case?
You probably have the grasshopper instance preview on... Turn of preview on the relevant grasshopper tool.
I have one question - how did you input model before all actions? In which format I need to save model for Rhino? Thanks!
You don't need to save the model in any specific format. You build you model in Rhino and when you are happy with it you link your model into a geometry container. You can find the containers for all kinds of objects in the grasshopper main library. First toolset from the left.
I recommend to watch some general grasshopper tutorials before jumping into Ladybug.
Hello, thank you very much for this tutorial. would you know why I dont have the ladybug_ladybug plugin? and also I only have the LB direct sun hours which as I see is not the same as the one you used?
This is an old tutorial. I'll try to update these at some point.
I can't bake it in version 18.00
Right click on the tool you want to bake and choose bake...
can u make a series on pollination and ladybug and what they different
I might do, but probably after the Ladybug series. I have only read through the description. In general i think it has the same functionality as the ladybug tools but is computed in the cloud. Meaning that the calculations are most likely faster. I think it's also geared towards more readymade workflows. And there are paid plans... It also needs a slightly different setup but i think with learning the Ladybug tools you will automatically know how to use pollination.
@@PhilippGalvanDesign Yeah it is true, thank u for all courses u made available on the channel
Help! how can I fix my ladybug ! 0:47 there is a 3x3 table of green squares, but mine is different... the one on the right corner of the first row is red, whole second row is blue and third row is blue!
hey Visatos, the 3x3 table appearing when you start GH are Quick access to previous grasshopper script files you worked on. Green means it was saved and found by Grasshopper. Red means the file was not found. (maybe was not saved or was moved or deleted) If there is no file name in the blue rectangle i guess they are just placeholders.
The rectangles are not linked to the functionality of ladybug, you should be able to work without problem.
I can only say, always save your work and scripts you are working on.
Hope it makes sense.
Cheers
Thank you so much for this amazing tutorial! But I encountered some problems when I tried to bake the result of grasshopper. After I enable the sunhour component, though there are ladybug bake layers in Rhino, there's nothing shown on the screen. Do you know how I can solve the problem?
hi muyun - not 100 percent sure what the problem is. Are there any objects in the ladybug folders?
if yes, make sure that you are in the correct display mode. or adjust your display mode to show colored meshes.
Before you bake the result, did you see the colored mesh in the viewport?
many questions - if you can't make it to work you can also send me an email with the GH definition and I can have a look.

Amazing tutorial! I have just one question: is it posible to take a capture or print the final result? Do you need to render it or something? Thank you!
@Raquel Peña - after you baked the result the coloured mesh is inside your rhino file.
The coloured mesh is not a material so can't render it with vray for example. However I normally use a nice display mode and the print function or the capture viewport command. Which is: "_ViewCaptureToFile'. Which I use most often for diagrams since you can control the resolution and file format. its perfect for print or web presentations.
Hope that helps.
@@PhilippGalvanDesign Thank you so much! I though about render it at first, but the ViewCaptureToFile comand seems a more accurate solution. Thank you so much and happy new year!
help, why do i have a different component although it has the same icon but not the same set of words
@Jane W - hi, yes you probably installed the latest version of Ladybug. I just uploaded a follow up tutorial today building the same script but with the new Ladybug version.
So please check my latest video.
@@PhilippGalvanDesign Thank you so much for the fast reply
Thank you very much for this video! Do you need to download Radiance in order to get the Sunlight Hours Analysis tool? It doesn't seem to be showing up in my Ladybug toolbar.
@Sustainable Living Japan - no, you don't need Radiance for this script. But it could be that you have a newer version of Ladybug installed. For that you might want to check out my latest video on the same topic with the latest Ladybug tools.

Philipp Galvan Great, thank you so much!!
Hi, first of all thanks for this tutorial. While trying out the script you described in this tutorial, I run in a problem, since the LB sun path component will not return any vectors to input in the LB Direct Sun Hours. Any suggestions? Thanks
Hey Flavio, I guess you are working with the latest Ladybug version? Ladybug tools 1.1.0? Have you provided a time (hoys)?
If the time is set to an hour were the sun hasn't risen for the specified location then it can't return a vector. Normally the time is set to 0. That would be midnight.
Don't know if that is the problem you have with the script. I just tried it here and it works.
@@PhilippGalvanDesign Hi Philipp, setting the hoys surely has moved something forward, the vectors can now be read, but still I cannot visualize the script correctly. In fact as further proof, if I run it it will not work. The constant upgrade of Ladybug is kind of tricky as all the tutorials I find are made based on the old version....
@Flavio Recchia - Yeah agree, the new Ladybug tools are definitely a bit different, and it is a bit frustrating with keeping up with the updates. However, I can see that the developers rethought some of the concepts to make them more straightforward. Since there has been some confusion and question also from others I decided to prepare a follow up tutorial today. Will upload later or tomorrow.
@@PhilippGalvanDesign looking forward to watch it.
@Flavio Recchia - uploaded here: ua-cam.com/video/Pb1CO66qJGE/v-deo.html - hope it works for you. Let me know if you still have problems with it.
Hi, ich have a question, i have only six panels and 94 components in my ladybug folder, also ist the first Radiaton panel , you are using, in my gh missing. At the same Symbol i can only find the incident radiation panel. I did anything as you said at Installation, do you know, what ist missing? Greetings
Which version of Ladybug tools have you installed? This script was for the legacy tools.
If you installed any of the new Ladybug tools version (1.1 to 1.5) then you need to follow this video:
ua-cam.com/video/Pb1CO66qJGE/v-deo.html
That reminds me that I need to clean my channel better so people find the right videos.
Tank you so much for answering, yes it ist the newest Version. Im currently consuming dozens of Videos a day for a school Projekt, a kinetic building with changing facade to sunpath(as a gh and rh newby). I will follow the other video guide.
Perfect
Hi Philipp! Thanks for this video it is super helpful. Have you ever seen or run into the issue of the vector output from the Sun path tool not properly loading into the Direct Sun Hours tool? I am getting the error message that "Input parameter _vectors failed to collect data".
I was having issues loading a weather file .epw at first but was able to properly download onto my desktop. I thought the issue could maybe be related but I'm not sure why it would be.
Yeah I had that issue.. ok so what I would do is trying different weather data files. Even though it might have downloaded it doesn't mean that the file is ok. Try something very obvious. Airports normally have a good working weather data.
Some weather data files are not working....because they haven't been maintained properly.
Where you successful with other weather data files? Or does the problem still persist.
@@PhilippGalvanDesign Hi, I also tried to try different weather data files but I still have "Input parameter _vectors failed to collect data" too.
@@user-hi4gp3xe8s which version of ladybug are you using? Legacy tools or new ladybug tools?
@@PhilippGalvanDesign Hi, it has been resolved, I watch your updated sunhour analysis with latest ladybug tools video! Thank you :)
Thank you sir
But if we don't have epw file of of location that we want the how can i do the study?
Or is there any way to get epw file of specific location?
Yes so for this study I think you only need the coordinates. There is a tool in ladybug with which you can create a location.
I can do a video about it at some point.
This is actually a very good question.
Thanks for asking.
Best
Philipp
Thank you sir
climate.onebuilding.org
This is another link from where we can get epw files which are not their in ladybug epw and energy +
Will you please tell More about result/chart which is with the study and and how we can design better with this data
@@rohanpanval3982 good idea - in terms of design are you an architect, urban planner, or landscape architect?
Yes sir I'm student of Architecture from india
Were you using a SketchUP 3D? or AutoCAD DWG?
I never used Sketchup. I use AutoCAD sometimes, but not for this tutorial.
This is all Rhino3d.
@@PhilippGalvanDesign can l use Sket models?
@@LeandroGalvao.arquiteto hi, rhino allows for skp files to be imported. But it depends on the release. When skp are imported into rhino they will be translated to mesh model. Mesh models can be used without problem in rhino and ladybug. Hope it makes sense. Cheers
Hi i imported the site with buildings from cadmapper, now it looks like i made all the buildings from rhino, but when i go to brep and select them, it doesnt select them? Please help!
Your buildings from cad-mapper are most likely meshes. So you need the mesh container instead of the brep container.
@@PhilippGalvanDesign i managed to get it! But now after doing the sun , all words numbers are way too big and overlapping. How do i make the font size smaller? Thankss
Not sure. What unit systems are you working in. What are you files unit? Meter? Millimeter? Inch?
@@PhilippGalvanDesign centimeters, when you are putting numbers in the sliders are those considered in meters?
The slider represent the units you are using in your file. If you are using millimetres it's gonna be millimetres if you are using meters then it's gonna be meters etc...
I would highly recommend to us meter as a unit systems for all your models when working with Ladybug.
Ladybug is set up to work in meter.
So i would encourage you to use meter otherwise you will create wrong output.
i knew i will have some problem doing it ,,, where is my ladybug !? why is it not there ahahah
@FRIKT - Ladybug is not part of the default Grasshopper and you need to install it first.
You can download it for free from food for rhino. There are 2 version of Ladybug - Legacy tools or Ladybug tools 1.1.0
This tutorial is for the legacy tools. For the same script but for the new Ladybug tools 1.1.0 please watch my new video: ua-cam.com/video/Pb1CO66qJGE/v-deo.html.
Hope that helps. You can also install both versions at the same time.
@@PhilippGalvanDesign thanks ! I try and install it and get back to you if it worked for me.
Yes, let me know how it goes.
