Instructions for creating an hourly EPW weather file in Meteonorm 6.1 1. Start Meteonorm.
2. Click the Continue button (top right). The Site tab appears.
3. Next click on Station as the Type of Site under the Choose site group, then select the continent in the Part of the World section.
4. In the Search site box, enter the first one or two characters of the desired location name with a * and click on the Search Site button. (For
example, searching for London, enter lo*.)
5. Select the site name (if available) from the list, click the Continue button, and go to step 6. If the site doesn't have a Station available, go to
step A.
6. After clicking on the Continue button, the Data tab appears. Click the Default values button (or make changes) and then click the Continue
button.
7. The Format tab appears. Select EnergyPlus (in the middle section, Building Simulation), and click on the Continue button. Meteonorm will
then give any warnings about the data in a pop‐up. Write down the warnings (in an .info file) and note that you used Station, Station (GH
interpolated), City or User defined location, and the version of Meteonorm used.
8. The
Calculations
tab
appears.
Click
the
Save
button
(near
the
bottom),
and
give
the
new
weather
file
a name
when
prompted
(should
end
with EPW). (Use the ISO 3‐letter country abbreviation followed by the city and the format. For Kathmandu, Nepal, this would be:
(NPL_Kathmandu_MN6.epw)
9. Two options for creating the final .EPW:
Create a .DEF with the station name, country abbreviation, latitude, longitude, elevation, time zone, and comments indicating the
Meteonorm source. Look up the WMO code in the ASHRAE list of stations or the WMO flatfile.
Edit the .EPW in a text editor, changing the station name field, state/province field, country abbreviation as needed. Look up the
WMO code in the ASHRAE list of stations or the WMO flatfile.
10. Run the EnergyPlus WeatherProcessor to get a Statistics report. Review the report to ensure all the data is available and is reasonable.
11. Create and post a .ZIP file containing the weather file on the EnergyPlus_Support YahooGroup under Files/Meteonorm_Weather_files. The
.ZIP should
include
the
.EPW,
.DDY,
.STAT,
.AUDIT
and
the
warnings
text
file
you
created
(give
it
a .INFO
extension).
Your new file is ready.
If no Stations are available for your location, try this:
A. On the Site tab, click the Stations (GH interpolated) button and select the continent again.
B. In the Search site box, again enter the first one or two characters of the desired location and click on the Search site button.
C. Select the site (if available) from the list and click the Continue button. If there isn't a site available, go to step Z. If there is a site, go back to
step 6.
Last resort! Try this:
NOTE: Quality of data declines exponentially if no Station data is available. These data are often interpolated from locations many kilometers
away (up to 1000 km!). Steps Z‐X should only be used if when no other data are available.
Z. On the Site table, click the Cities button and select the continent again.

Click the Save button and the OK button. Click the Continue button and go back to step 6.
