[EnergyPlus_Support] Re: Weather file Convert

["hbn_pch" <hbn_pch@xxxxxxxxxxxx>]

Dear Joe,
  The weather file i used is just what you and Dr. ZHANG Qingyuan 
developed,ah.I've read the book that you and Dr. ZHANG Qingyuan have 
wrote about Typical Meteorological Database for Building in China.It 
is so useful for our building design.Now i'm studying and using 
Energyplus to simulate the building and  do energy analysis.But i 
found that the weather data format you and Dr. ZHANG Qingyuan 
developed can't match the Energyplus weather data format.So i want to 
find a way to convert it.
  I thought *.dat file is SAMSON Data file,but find that *.dat file 
you developed is a custom format.I want to find an approach to 
convert the format.
  Thanks.
  
  pch
