[TRNSYS-users] Weather data read-in

[Matt Duffy]

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 ".WeatherMeteonormAsia" 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 ".ExamplesReading Data Files" directory. 

Best regards, 

Matt

(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.

find the file including the original Energy+ weatherdata and outputs
from TRNSYS.
