Hourly radiation data

Hello , I’m trying to make a list of data of solar radiation incident on a vertical surface . What I need is a list of all hourly values ​​throughout the year, but I am not able to do it with Ladybug. Is there a way to do it?


Hi Simone,

You can do this with Ladybug, although I will admit that the current workflow for this is not ideal and is more time consuming than necessary. In the future, I plan to make a component that can do this easily and quickly using a method that I wrote into the solar temperature adjustor component (right now this is only working for a mannequin mesh and not any geometry that you want, though).

Attached, you can find a file that shows you how to do what you are asking. Be prepared to wait ~10 minutes or so until the slider finishes animating. In the future, you should be able to do this in parallel and this will get the run time down to a minute if your geometry is simple.

Let me know if you have any questions,

Hi Simone,

Chris’s method does what you need. You can connect a series of numbers and graft them instead animating the slider and then remove record component and the panel for faster calculation.

You can also use annual daylight recipe with Honeybee, and change the type to radiation analysis. Then you can use read hourly results from annual study to get the results for all the hours.


Ah right. The grafting method Mostapha mentioned will probably give you a result much faster. I attached an updated GH definition with this method. Thank you, Sir Sadeghipour!

Hello everyone! I solved as soon as I wrote on the forum with the metod suggested by Chris, …but the second is even faster!



Hello, I am trying to download the model and it appears as private link.
