SOLAR: How to get individual results from a group of buildings?

Grasshopper

Hi,
Does anyone know how to get individual results from a group of buildings, as opposed to a overall output? i.e Providing six (6) results (yellow buildings) for solar insolation of the buildings.

Thanks,

Hi.

Can you explain your issue with more detail?

sure, I was hoping to improve the efficiency of my solar analysis script by running the analysis on all buildings (the yellow above) at the same time, but provide the results split into individual buildings. For example, the overall solar insolation might be 65% for the total facades; but individual buildings may have results of 70%, 55%, 62%, 68% etc.

so i guess i’m trying to figure out how I regroup the analysis points results to their respective building.

Hi @Oscar_James,

This sounds like a grafting/data tree problem.

Grafting let’s you run multiple “things” through a single component or chain of components but keeps each initial input in its own data tree branch.

Allowing you to gain performance, not duplicate code, and keep results manageable and “sesperate” still.

We need to understand what/how you are performing the solar analysis.

Can you please upload a grasshopper script of the simulation portion?

Thank you!

Hi Michael,

I have attached the script thus far.
Yes, I think grafting or grouping the data is the issue. I can’t seme to work out if it need to be done before or after the DirectSunHrs analysis.

Thanks @Oscar_James,

But you need to provide the .3dm as well since you dynamically reference the geometry of the Rhino scene in your script.

Alternatively right click on the geometry input nodes and choose “Internalize data” which will embed the references into the grasshopper file.

Do this for the nodes connected to your Geometry Pipeline nodes:

Once you provide that info we can take a look

Apologies @Michael_Vollrath!
I have attached the file.
Thank you for your assistance!

@Oscar_James,

What ladybug version are you using?

You may want to investigate the Cyclops App as well

Hi Michael, Ladybug 1.4 and 1.8 I believe

Thanks!

Does this allow for individual results per building to be shown, when multi buildings are being analysed?

It’s designed for large urban context models so I would have to think you should be able to extract as much data as you want.

And it’s free (and seemingly well documented).
