An online viewer and analysis tool for EnergyPlus Weather (EPW) files.
EPW files can be downloaded from epwmap, One Building, or the EnergyPlus weather website.
When an EPW file is parsed, epwvis now computes additional psychrometric properties (wet-bulb temperature, humidity ratio, specific humidity, vapor pressure, moist-air enthalpy/volume/density, and degree of saturation) using PsychroLib.
See the Wiki tab for more details on how to interpret weather data for environmental design and building energy modeling.
- Please suggest visualizations you would like to see and report bugs in the Issues tab above.
- If you would like to contribute a visualization, code it up, write a section on the wiki on why it is useful and how to interpret it, and then send me a pull request.
- Thanks to Mostapha Roudsari and Chris Mackey for Ladybug python code for parsing EPW files. Other EPW parsers from lmnarchitects and René Buffat's pyepw were helpful references.
- This tool uses D3.js developed by Mike Bostock, crossfilter.js, and PsychroLib.
