Gismo + Ladybug + ENVI-met connection

What happens when a penguin and a ladybug work together? A ladyguin!! :)

Ladybug developer Antonello Di Nunzio has recently released a set of components for Ladybug which enable preparing, modelling, and visualizing data for ENVI-Met 4 software. ENVI-met is a cutting edge software used to analyse microclimate interactions in urban environment. Tens of different analysis types can be performed on the chosen building context. From Mean radiant temperature and local Wind speed to CO2 concentration and Pollutant dispersion in the air.

To generate the building context for Ladybug ENVI-met components, Antonello used Gismo:

An example similar to results in upper screenshots has been been attached below.
To run it, Gismo, Ladybug and Human plugins need to be installed.
To perform the ENVI-met analysis, download ENVI-met 4 Basic for free, and install it.

Steps in the .gh example file have been labelled from 1 to 11. They mostly consist of just setting a boolean toggle to True.
An exception to this are steps 6 (set the folder path of your ENVI-met application install folder), and 8 (running the ENVI-met simulation). Step 8 has been explained in detail in the photo attached below (step8.jpg).

Special thanks to Antonello for developing and guidance on ENVI-met application and components!
Post questions below if you have any issues!

Hi Romain,

You can find the latest release of lb_envimet on github, here is the link:
https://github.com/AntonelloDN/lb_envimet

Installation instruction:
1) click on "clone or download" and download lb_envimet master
2) extract it wherever you want in your machine
3) copy "lb_envimet" folder in APPDATA/ROAMING
4) Drag and Drop all components which comes from "UserObjects" into the canvas of Grasshopper

Let me know if it works.
There are also some examples in the folder "examples".

Please, let me know if it works.

This plugin is based on the basic version of ENVI_MET. Is the variable you are looking for part of ENVI_MET PRO?

Thanks
Antonello

Thanks Antonello,

I've tried it, unfortunately I have the same error message for several components related to the __init__.py file (see attached). Any idea how to solve this issue?

Hi Romain,

I have fixed a bug, could you download and install the version you can find on github again? Thanks

Regards,
Antonello

Hi Antonello,

(I commented on the youtube video, but perhaps you don't access youtube that often to see it)

Is the demo video supposed to be cropped? I'm trying to follow but sometimes I can't see where you click and get the components from...

Another question (I haven't tried the program yet!): is it possible to do the reverse, i.e., convert building geometries from Envimet to Rhinoceros?

Thanks!

Ciao Antonello,

i link a envimet basic non funzionano più. Oggi è scaricabile la versione Lite, con durata 30gg. Non so se questo abbia ad oggi costituito un freno allo sviluppo del plug-in.

Sto provando a seguire i tutorial e l'esempio ma il problema maggiore deriva dall'Envimet manager workspace. Crea una cartella ma non la riconosce, o almeno così mi sembra di aver capito. Qualsiasi info riguardo alle considerazioni precedenti sarebbe utile.

Ti ringrazio per il tuo prezioso lavoro,

Un saluto,

David

Hi David,

About tutorials and manage workspace folder, are you using Dragonfly Legacy envimet components? https://github.com/chriswmackey/Dragonfly

Thanks,

Antonello

Hi Antonello,

no I used your previous component for Ladybug, and yesterday I tried with Dragonfly. Regarding Envimet simulation, I read your Wiky page and it talks about Envimet 4.1.1. Is it for free? or Drangonfly is stricly related to a software with commercial license?

Thanks in advance,

David

Hi David,

Wiky is not updated, I must update it. Free version of Envi Met 4.1.1 was similar to latest one, maybe less limits, however it is not available anymore. The current version is Envimet 4.4.3.

Dragonfly does not take care of license type, it is theoretically compatible with all Envimet versions. You could use it also with trial one, but I know there are limitations with trial, starting from grid dimensions.

Regards,

Antonello
