[TRNSYS-users] TRNSYS Weather File Construction

  I would try and find an hourly data file for a location that is near 
to the RETScreen location. TRNSYS reads half a dozen or so different 
weather data file syntaxes and there is a data base of Canadian weather 
in *.epw format that has a pretty extensive site list. There is a 
component in Trnsys that will generate hourly data based on monthly 
averages but not one that will do so based on daily data.

kind regards,
