Re: [EnergyPlus_Support] discrepancy of weather data in epw file and csv report file

[Rahul Chillar <chillarrahul@xxxxxxxxx>]

hi
No , it does not matter . The program does calculations in time steps , temperatures at those time steps are are calculated by division of an interval of temperature from the weather file and when the various temperatures are added back to give final temperature the report variable, they will not be same due to addition of truncation errors.
It does not affect the results at all.

I notice that the same weather data (such as the Outdoor Dry Bulb 
and Outdoor Relative Humidity) are slightly different in the epw 
weather file and csv report file.

Does it matter ?
