<DIV>Actually there may be an even better way. We just announced at last
week’s American Meteorological Society conference a new system that can provide
EnergyPlus (EPW) files in any of over 600,000 locations worldwide. We have
essentially placed a virtual weather station every 35-km across the globe.
Each able to produce gap-free hourly weather for over 30 years and full TMY
energy+ files on demand. We have been working on this a long time and it
is now available. We do not interpolate or extrapolate but use the new
high resolution NOAA/NCEP/CFSR and the NASA/MERRA data sets as our base.
In tests where we placed a virtual stations right next to certified met
stations, the outputs were essentially the same.</DIV>
<DIV> </DIV>
<DIV>If you are looking for energy+ data where you could not get it before, let
me know. The people who have tried it from all over the world have been
very happy with the data.</DIV>

<DIV>Best,</DIV>

you should be aware of Meteonorm limitations:<BR><BR>Meteonorm extrapolates
hourly data from statistical data for a <BR>location. Where statistical data
aren't available, Meteonorm interpolates <BR>from other nearby sites. Generally
a statistical approach is a last resort--<BR>weather files generated from
statistics will not demonstrate the normal<BR>hour-to-hour and day-to-day
variability seen in measured data.<BR><BR>Each .ZIP includes a .STAT (EnergyPlus
weather data statistics), .EPW <BR>(EnergyPlus weather file), and .INFO
(Information about the source data and <BR>limitations from Meteonorm).
<BR><BR>IN ALL CASES, YOU SHOULD REVIEW THE .STAT FILE FOR THE LOCATION BEFORE
USING <BR>ANY OF THESE FILES TO ENSURE THAT IT REPRESENTS THE CLIMATE OF THE
LOCATION AS <BR>YOU UNDERSTAND IT. IN MANY CASES, A NEARBY LOCATION WITH
MEASURED DATA MAY BE <BR>MORE APPROPRIATE THAN ONE DERIVED FROM STATISTICS.
<BR><BR>YOU USE THESE FILES ENTIRELY AT YOUR OWN RISK.<BR><BR>As always, if you
know of sources of weather data that we might be able to <BR>share with the
EnergyPlus community, please contact us. <BR><BR>EnergyPlus Development
