Hi everyone,
I need to create an EPW file from bioclimatic data that I will collect myself using sensors (is that practicable?), because this data set should reflect the microclimate around a specific building and be updatable and usable for simulations. Could you recommend a way to structure this data set in an automatically populated EPW file so that it can be read by Grasshopper for use in various Ladybug Tools simulations?
Hi @deborax this might help: Elements by big ladder software
*Elements* is a free, open-source, cross-platform software tool for creating and editing custom weather files for building energy modeling

The simplest method I have encountered is not 'automatic '.
It is easiest if you install a full copy of Energy Plus. To make your life easier, choose the same version as LBT/ Pollination.
It comes with a bunch of utility programs. One of these is a weather file converter. It takes the epw file and helps you to write a .csv file. This file has the advantage that each column of data has a header telling you what it contains.
You then can use this in a spreadsheet program to replace the relevant columns of data with your own data. With care, you should remove data from those columns where you have no data. Do not delete columns
Save this back to a .csv file and use the E+ weather utility to creat a new epw.

Hey,
You can use Dragonfly to do so, from tab 6 of DF you can find “DF Create EPW” component
