Thank you for Uploading the video content on energy modelling and daylight performance by Honeybee and Grasshopper. It helped to my research work also. Now I have encountered a problem related to Honeybee visualize. Actually, we made a model in Grasshopper and want to analyze the energy consumption by Honeybee. Now as defined in your video that if we attached the Honeybee adjacency for a separation of each building spaces. Then the visual impact is not clear shown. It means when we put of the "Preview" then the model visualization as per your video not clear shown. Kindly guide me how we can do this.
Thank you for the videos. I started learning honeybee, ladybug with your videos and they are very helpful. I have a question. For my study, I want to simulate just one floor with 5 zones (north,west,south,east zone and core) in multistorey office building (20 floors) . I want to simulate just 10th floor but remaning floors should be there with same floor arragement and glazing ratio since they also affect energy loads for top and bottom. How I can arrange my simulation?
Thank you for the video! I am having a problem, when I plug in “Visualize by type” and then “mesh” it’s not showing me each division on the Rhino file. Is there something I’m missing?
Hi Mr. Phillip, After performing a simulation using Honeybee, I expect to access the simulation results directly by opening the 'eplusout.sql' file within the 'simulation' folder, which generally houses all the energy usage data. However, when you try to open this 'eplusout.sql' file using Navicat, you notice that the contents display garbled text. What could be the reason behind this problem?
Hi I haven't tried Navicat myself but it's most likely an encoding problem. Where the SQL database is probably not the problem. The text file containing the database the code is written in a way Navicat doesn't understand.
Maybe one of these options might lead to a solution: Using Navicat's Encoding Options: Open the eplusout.sql file in Navicat. Look for an option related to "encoding" or "character set" in the import settings or file menu. This might vary depending on the specific Navicat version you're using. Try opening the file with different encodings like UTF-8 and CP1252. One of these might be the correct encoding for your file. Using a Text Editor with Encoding Conversion: Open the eplusout.sql file in a text editor that supports encoding conversion, such as Notepad++ or Sublime Text. Most text editors will have an "Encoding" option in the menu bar or under "File" settings. Look for a "Save As" option with encoding selection. Choose UTF-8 (universal encoding) as the new encoding and save the file with a new name (to avoid overwriting the original). Try opening the saved file in Navicat. Identify Encoding and Convert with External Tool (if necessary): If the first two methods fail, you might need to identify the original encoding of the file. Some programs show file properties that might include encoding details. There are online tools and standalone software for encoding conversion. Use one of these tools to convert the file to UTF-8 and then try opening it in Navicat.
Have you found a more elegant way to assign room labels/build the model by room? i.e. if you are working on a large project with say 500 rooms, (organized by layer in rhino) it would be impractical to assign each one as you did in the beginning of the video. But they need to be imported together to use the intersect solids component. Thank you! I love your channel!
Hi Emily, good question. Yes for a 500 room hotel or hospital it would be impractical. I would probably combine first all rooms by category. You can input more the one geometry into one honeybee room component. I should make a video... :D
@@PhilippGalvanDesign does that still require connecting each of 500 breps to a room category? I connected up a work around... which adds groups of geometries into the intersect solids component in order and then pulls them from a list in that order... but this is pretty clunky and not at all foolproof. Anyway, thoughts appreciated!
No, that's what I meant, you can place a brep container with your geometries (any number of boxes with the same category) into the HB room tool. For example I have a hotel with 200 double and 100 with king-size bed rooms. One brep container for your 200 double bedrooms and one brep container for the 100 king size bedrooms. In reality it's probably not that simple. For larger projects its good to think of how to organise the script to be economically and flexible at the same time. For a hotel with a lot of repetition I would probably solve it floor by floor....
Hi. I just want to suggest you that you should use Open studio component instead of energyplus . In OS component you can simulate varied Air conditioning system which can throw error otherwise directly in eplus. Before starting this seriess you should also describe how it translates the data to OS and one can change data in OS app
Hi Asis, thanks for the valuable insight. It seems you have already more advanced knowledge about the different components. Would be interesting to know where or how you learned the craft. I hope I get there too at some point through exploring.
@@PhilippGalvanDesign Thanks for replying. I am using this tool kit since its birth. The most of it I learnet from the Ladybug Discourse discussions! I loved your honeybee radiance videos! Keep up the good work! I had also added a video on advancement with honeybee radiance ruclips.net/video/CWcR2SNO32U/видео.html
Do you know why when I change the link between HB visualize by type and mesh, for the various types (ex. walls, interior walls, ceilings ..etc.) nothing seems to change visually on the model? The model continues to just display the walls as yellow surface no matter what i do. I also can't get the red surface previews to disappear even though I've turned previews off for everything. Do you know why this might be?
If you have turned the preview of all components off you shouldn't see anything. How about your grasshopper viewport options? You might want to send me a grasshopper screenshot or the script so i can check what the problem is. office@nedomlel.com
I have no access to a computer right now. Currently on holiday. Back in 2 weeks. You need to be a bit more specific. Where, when and how does the fatal Error occurs? Any red components etc....
Hi, I've been going through your series and really enjoying so far. I've been trying to build the model for this, and follow your steps so I can progress, but its just not playing ball, is there any way you could send me a copy of the model so I can use that to get going by myself and not spend ages trying to find where I've gone wrong? Thanks in advance.
Hi Thank you so much for the video!!! It helped a loooot!! Have one question here, I tried the solve adjacency, but for my rooms (with a 30 deg angle), part of the roof is not shown after using this tab. Does anyone know how to fix this?? Thanks in advance for your help!!
@@PhilippGalvanDesign Thank you! I'll check out the video u made about that. But btw my roof is just with a slope not curved (less than 30 deg slope, but it will only get recognised by HB if I key in 40 deg and above) and even with that, part of the roof is not recognized after going through adjacency.. which I havent found out why @.@
Hello, I get this message "1. Solution exception: ** Fatal ** GetSurfaceData: Errors discovered, program terminated." and I don't know why in the part of the HB Annual Loads component
I your case I would look into the example files and see if they are working. If they don't then something is wrong with your installation. You can find the example files in the Ladybug tools installation zip file.
Brilliant series, all through to the radiance and wind simulation.
Thanks
I have an energy saving house design competition and this clip helped me a lot.
Great to hear. Thank You.
Wholly Guacamole! This is going to be a super intense HB series! Go Philipp!
Yes it's gonna be a steep hill to climb.

Not sure really, you could maybe simplify the other floors into single zones(rooms). It's a simulation at the end. I will have a think about it...
thanks Mr phillip for this great tutorial, please make a video about : how to make a custom program
Let's explore the existing programs before we jump into the nitty gritty of custom program. But at some point yes we should.
Thank you for the video! I am having a problem, when I plug in “Visualize by type” and then “mesh” it’s not showing me each division on the Rhino file. Is there something I’m missing?
Not sure really, I might need more information to be able to help.
