Dear Yuanli,
I did not happen to see a Beijing Energyplus weather file (*.epw) in the list of provided files.
http://apps1.eere.energy.gov/buildings/energyplus/cfm/weather_data3.cfm/region=2_asia_wmo_region_2/country=CHN/cname=China
I would speculate that perhaps the file that you had was not formatted exactly how the other *.epw files are formatted. However, for TRNSYS users, there is a Meteonorm file that is included for the Type15-6 for Beijing in the ".\Weather\Meteonorm\Asia" directory. Also, since you already have the data in column format, you could simply save the worksheet as a tab-delimited text file, and read that text file into your simulation with the Type9 data reader. Please see the example in the ".\Examples\Reading Data Files" directory.
Best regards,
Matt Duffy

Dear TRNSYS users,I read-in .epw weatherdata of BeiJing, China from Energy+ in TRNSYS (TYPE15-3). But the output wind speed and wind direction in TRNSYS are different from those source values in Energy+ weather file. And the wind speed is much smaller than the actual wind speed.Attached please find the file including the original Energy+ weatherdata and outputs from TRNSYS.Can anyone help me solve this problem?Best Regards.Yuanli
