| EnergyPlus Weather Data Format | U.S. Department of Energy | Data Files |
The EPW file extension stands for EnergyPlus Weather Data File, and it is a standardized file format used for storing geographical weather data. Developed by the U.S. Department of Energy’s National Energy Technology Laboratory and eQUEST software, it is primarily used to create reliable weather data for building-related simulations that feature cooling or heating loads as well as system performance.
Technical Details
The EPW file is unified with the general structure of EnergyPlus, which is a complex simulation engine based on energy modeling and computer simulation program. This type of text file contains vast amount of information related to the useful energy rate, ambient temperature, direct normal irradiance, global horizontal irradiance, atmospheric station pressure, precipitable water, wind direction, humidity, dew point temperature, wind speed and other details. It stores data using several different formats for values such as temperature in Celsius or Fahrenheit, precipitation in inches or millimeters, wind speed in meters or kilometers per hour.
Apart from being related to .EPW, some similar format files include .VF3, .DAT, .INP, .TXT, .PRJ, and BLDG.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .EPW) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .EPW extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .EPW file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .EPW extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .EPW extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .EPW file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .EPW file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .EPW file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .EPW file) will be extended to the maximum.
It is also good to check
- if the .EPW file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
