How to open EPW file?
The most common problem when using EnergyPlus Weather Data Format is that a specific EPW is not associated with the program. This is manifested by the fact that EPW files open in unusual applications or do not have an assigned program. This problem can be easily remedied.
The first thing you should do is just "doubleclick" on the EPW file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.
Step 1. Install Ecotect Analysis
In this case, you should first verify that the Ecotect Analysis application is installed on the computer. This can be achieved by typing Ecotect Analysis into the operating system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file EPW with Ecotect Analysis. Below you will find a list of applications that support EPW files.
Programs to open EPW file
Remember to download programs supporting EPW files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Ecotect Analysis with EPW files
If, despite the installed application, the EPW file does not start in the Ecotect Analysis application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the EPW file with the Ecotect Analysis application.
Step 3. Update Ecotect Analysis to the latest version
If, however, after binding Ecotect Analysis with EnergyPlus Weather Data Format there were still problems, you should update the program to the latest version.
Step 4. Check for the following problems with the EPW file
The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:
Very often, the file may be size 0 or incomplete. This suggests truncating the EPW file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. However, it is important to scan the entire system, not only the file EPW or the program directory. Sometimes virus-infected EPW files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the EPW files changes over time. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for this. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular EPW file corruption.
The program can also signal the fact of encryption. The encrypted EPW files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. The problem is only writing to the file, not reading it. Copying the EPW file to another location will fix the problem.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the EPW file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
