Remember, meteonorm files are statistical in nature and may not be
appropriate:
The EnergyPlus team can provide weather files appropriate for energy
simulation created using Meteonorm. These are posted on the EnergyPlus
YahooGroup under Files > Meteonorm_Weather_Files. Locations are listed
alphabetically by continent (WMO region) and country. More than 300
locations are currently available--look there first before asking for a
new weather file.

Information on selecting weather data appropriate for energy
simulation is described in this paper:
Drury B. Crawley. 1998. "Which Weather Data Should You Use for
Energy Simulations of Commercial Buildings?" in ASHRAE Transactions,
pp. 498-515, Vol. 104, Pt. 2. Atlanta: ASHRAE. (PDF 197 KB)
Requesting Meteonorm Weather Data for Your Location
Send the required information described below
In your message, you will need to send:
Name of Location (including country and state/province, if
appropriate)
Latitude (N+/S-)(decimal format required)
Longitude (E+/W-)(decimal format required)
Time Zone (+/- GMT)
Elevation (meters)
NOTE: It can take a few days for the weather files to be
created. Creation of the weather files is done on an unpaid,
volunteer basis.
And you should be aware of Meteonorm limitations:
Meteonorm extrapolates hourly data from statistical data for a location.
Where statistical data aren't available, Meteonorm interpolates from
other nearby sites. Generally a statistical approach is a last
resort--weather files generated from statistics will not demonstrate the
normal hour-to-hour and day-to-day variability seen in measured
data.
Each .ZIP includes a .STAT (EnergyPlus weather data statistics), .EPW
(EnergyPlus weather file), and .INFO (Information about the source data
and limitations from Meteonorm).
IN ALL CASES, YOU SHOULD REVIEW THE .STAT FILE FOR THE LOCATION BEFORE
USING ANY OF THESE FILES TO ENSURE THAT IT REPRESENTS THE CLIMATE OF THE
LOCATION AS YOU UNDERSTAND IT. IN MANY CASES, A NEARBY LOCATION WITH
MEASURED DATA MAY BE MORE APPROPRIATE THAN ONE DERIVED FROM
STATISTICS.
YOU USE THESE FILES ENTIRELY AT YOUR OWN RISK.
As always, if you know of sources of weather data that we might be able
to share with the EnergyPlus community, please contact us.
