Re: [EnergyPlus_Support] When Weather Data isn't Available on the EnergyPlus web site
For those of you that have Meteonorm, here are the steps I use
to create a weather file for EnergyPlus:
1. Start Meteonorm.
2. Click the Site button.
3. Next click the WMO/OMM button and select the continent. (WMO
usually means there's a weather station recording hourly data.)
4. In the search site box, enter the first one or two characters
of the desired location name and a '*' and click on the >> button.
5. Select the site (if available) from the list and click OK.
If there isn't a WMO site available, go to step A.
6. If the location is there, click on the name and Meteonorm will
give any warnings about the data. Write down the warnings (in a
text file) and note that you used WMO, Station or City data, and
the version of Meteonorm used.
7. Click the Format button, select TMY2, and click OK.
8. Click the Hourly Values button, then click the Save button and
gave the TMY2 a name when prompted.
(Use the ISO 3-letter country abbreviation followed by the city
and the format. For Kathmandu, Nepal, this would be:
NPL_Kathmandu_MN5.tm2)
9. Convert to EPW using the EnergyPlus WeatherConverter.
10. Post a .ZIP on the EnergyPlus_Support YahooGroup under
Files/Meteonorm_Weather_files. The .ZIP should include the .EPW,
.DDY, .STAT, and the warnings text file you created (give it a
.INFO extension). Save the TMY2 source and the .AUDIT in a separate
.ZIP but do not post it to the YahooGroup.
If no WMO data are available, try this:
A. Click the Station button and select the continent again.
B. In the search site box, enter the first one or two characters of
the desired location name and a '*' and click on the >> button.
C. Select the site (if available) from the list and click OK. If
there isn't a site available, go to step Z. If there is a site, go
back to step 6.
Finally as a last resort, try this:
NOTE: Quality of data declines exponentially if no WMO or Station
data is available. Steps Z-X should be used if when no other data
are available.
Z. Click the Cities button and select the continent again.
Y. In the search site box, enter the first one or two characters
of the desired location name and a '*' and click on the >> button.
X. Select the site (if available) from the list and click OK. If
there isn't a site available, you are out of luck. If there is a
site, go back to step 6.
