Grasshopper

algorithmic modeling for Rhino

Hi there! I´m starting to work with Geco now and I have an issue. One of the outputs of the EcoSun Rays component is Diffuse Solar (w). Does it only retreive diffuse solar radiation values? If that is the case, is there any other component to get direct solar radiation?

Hello owe,

is this what you want?

Sorry, you'll have to input the weather data. Use ecotect to convert .epw to .wea

Hi thanks! Well, what I need indeed is to get total solar radiation values as an output to then pulg it in as an input for another calculations I have to complete within Grasshopper. Using the EcoSunRays component you get Difuss solar (w) as an output, I need to get the total radiation as an output.

If I am not wrong, these values are the ones shown in the last ObjectRequest component in your code (Val(Wh/m2)) JPG attached.

By the way, I realize the name of the weather file is Alicante. Just in case, if you are Spanish let me know because I am Spanish and we may communicate better in our language ;)

Sorry you can find the JPG here

One more thing, how can you consider obstruction geometry to calculate solar radiation on other pieces of geometry?

Yes that would be it. The component at the bottom would also work, but I don't know why it didn't have the interval [I] values
connected. Just add the output [I] from [EcoMeshExport] to the input [I] from [EcoObjectRequest]. Those are values from each of the subdivisions of the mesh, so to get the total you'll have to use the [Mass Addition] component. 

The definition I gave you calculates the total radiation striking a surface during a time interval (with the [EcoSolCal] component). If you want to know the total radiation regardless of any surface I suggest you try Ladybug. 

I have not done any calculations with obstructing geometry. 

Feel free to contact me in Spanish. 


Hi Jesus! 

I have another issue. The "exposure" component in Geco calcutes the combined exposure for evry individual mesh that you introduce as an input "S". It also has another optional input, which referrs to obstructing geometry "O". Do you know if this component calculates the shadow that every single mesh introduced as an "S" input project on every other mesh just implementing these meshes as "S" inputs, or do you have to connect them also to the "O" input for the software to consider them as obstructing geometry?

Lets say the meshes you introduce as "S" inputs are terrazes that belong to a building because you want to know their solar exposure. Obviously a number of terrazes are going to project shadow on some other terrazes. I want to know if the component already considers that when you plug the meshes (terrazes) to the "S" input, or if you also have to plug them to the "O" input.

Thanks!!

to get the total radiation you have to multiply the area of the panel with the values as the unit is Wh/m². What do you mean with the total radiation?
