First steps into HoneyBee simulations

Hi Lukanuts, See me my comments inline. I'm 

Hello all, I am starting to investigate on energy and daylighting simulations in HB environment. Step by step I am currently studying all Youtube tutorials provided by Mostapha and Chris. As regard Chris's tutorial on energy simulation, I have this questions:

Rule of thumb for HB_solveadjacences is to create a sort of hierarchy among this component especially when you make some changes: eg If I want to add new properties in a specific zone (for example a new EPconstruction between two zone) I will plug this component setting to true "remove current adjacences" (if needed) before running the simulation. So I have the 1st HB_solveadj that controls the zones without changes and it is followed by other HB_solveadj for the modified ones. Is it correct?

Can you put a simple example file together to help me understand this question?

HB_generateEPoutput: Does surfacetempanalysis/surfaceenergyanalysis refer to surface baricenter?

What do you mean by baricenter?

Are E+ schedules related to Openstudiostandards.json?

Openstudiostandards.json includes loads and schedule information for programs (e.g openoffice) but the schedules are in OpenStudioMasterTemplate.idf

In the future are there any possibility to show a completion bar (for example in % like ecotect) for energy simulations? Or at least the percentage of completion similar to Radiance simulation Cmd panel, in order to manage my time because sometimes my pc is completely destined for this type of tasks.

Yes and no. There are discussions about this on the forum. The short answer is that it depends on the analysis type and we can use Rhino's progress bar.

Currently I am using LB_meshtohatch to export my results directly into illustrator (as vectors), and finally I use "export selected" in Rhino saving it as pdf, but this lead to a file with more mb than the ordinary. Due to this component my laptop becomes very slow. Are there any other component to obtain the same results?

(for example in ecotect you could export as metafile without having this heavy 3dm file.)

I have never used this workflow myself but can't you just delete them from the Rhino file?

How does Github work? Many times I have read in the forum that chris and mostapha fixed some bugs and, without creating a new release, they always have newer version of some components. In the image below I have found this new version of captureview: so by using HB/LB_update might I have new updated component everytime they are online on github? 

Whenever you use update components (and there is two of them. One for ladybug and one for honeybee) it will overwrite your installation and you'll have the latest development version which is available on github. If you don't use them you'll have the official latest stable release.

Last one: Yesterday I ran my first image-based daylighting simulation, unfortunately this morning I decide to rerun the same simulation and it gives me this error (first .gif) that i don't know how to fix (I've also tried to delete simulation folder and re launch it). On the contrary when I run glare analysis provided by mostapha everything goes well with HB_rundaylightsimulation component.

You need to internalize the geometries so I can try to re-create the issue. As far as I can see from the error message the analysis fails to run and it doesn't even generate an error.log.

I am very sorry for asking you all this questions at the same time, but I didn't find anything on this forum for some of my questions.

Thank you for posting your questions. I recommend to post your questions as separate discussions.

Hi Mostapha, thanks for your answer.

Below you will find the file you requested. You will see two consecutive HB_solveadj; I just want to understand the methodology for using correctly this component: whenever I make relevant changes in zone properties, especially when they are in contact each other, I should use this component another time before running simulations, shouldn't I?

By surface barycenter I mean the point of reference on the surface for which single results are related to: indeed I suppose, similarly to grid points of daylighting studies that are the points of reference of the tiles in which the grid analysis is subdivided, the outputs provided by HB_generateEPoutput (surfacetempanalysis/surfaceenergyanalysis) have a similar way of showing us the results.

I have changed the way of exporting the results after reading release notes where you explained the new features of "bake it"

Where can I find Rhino's progress bar? Can I recall it from rhino command bar? I have found this on the internet http://discourse.mcneel.com/t/sample-code-showing-a-progress-bar-du.... Currently I am not able to create codes.

I have internalized the breps as you requested for the image-based dayligthing studies

Thanks in advance,

Luca
