White Box Technologies has recently updated 2017 weather files
through October 8 for 8,298 locations around the world (2107 US,
289 Canadian, 5902 international). As a boon to EnergyPlus
users, a fix has been added to all historical EPWs to set
correctly the starting Day of Week for Jan. 1 instead of the
hard-wired default of Sunday (luckily, this is not a problem
with the 2017 files since Jan 1 2017 is actually a Sunday!).
The WBT web site also allows users to create composite year weather files, i.e., those whose data begin on Jan. 1 of one year through a user-specified date, followed by data from that date forward of a different year (typically the previous year). Such composite year weather files are useful for eQUEST users since DOE-2 assumes that the weather file begins on Jan 1 and ends of Dec. 31. However, if these files are used to calibrate against commercial building utility bills, adjustments must be made to the day of week schedules at the switchover date (I'll post some instructions and samples on my Web site, as well as include them with all future composite year weather files). Added to the weather files previously generated going back to 2001, the WBT Weather web site now contain 16-year time series of hourly weather for 6,500 locations, and shorter time series for another 3,500 locations. WBT can also create "typical year" weather files for any of these locations, although one should check first whether there's already a TMY3 for a US location, or a IWEC2 file for an international location. For a complete list of all 2017 files, please see here
for USA/Canada stations or here
for International stations.
