This script can be used to generate wind roses from the epw weather file. This script can also create filtered wind roses from filtered epw weather files.

Visualize EPW Sources in Interactive Maps

Use this script to convert .epw hourly weather file to csv. The csv-excel sheet can be used to sort dry bulb temperature and coincident wet bulb temperature and vice versa. This will give you accurate historical HVAC design conditions.

This script uses psychrolib library. Use this script if you want to extract wet bulb temperature using dry bulb temperature and dew point temperature. epw files contain only DBT and DPT. You can extract WBT using this code.

Use this script to merge .epw files into one file. This will combine each .epw hourly weather file into one .epw file. The hourly weather files of each year should be placed in the folder in chronological order.

Transforming historial Observed Weather Data from Meteo France (e.g. weather data of 2003) to EPW format to be used in Building Performance Simulations

WIP EPW format parser

Script that exports EPW files from NREL PSM3 weather data.

This script can filter the months, days and hours from the yearly .epw files. These filtered files can be used for generating wind roses for specific months/days/hours. The filtered epw files contain less than 8760 hours. Hence, these epw weather files cannot be used in energy modelling softwares.
