Output Date is 9/17 Rather Than 9/21

[Anonymous]

I am running analysis under LEED v2009 which requires the date to be Sept 21st. However, it keeps defaulting to be near the 21st and runs it on the 17th. Is there a way to correct this.

Thanks

This is actually as designed.  The LEED requirement states a 'clear day within 14 days of Sept 21 and March 21'.  We use actual weather data and automatically choose the closest date to 9/21 that has a clear sky measurement at 9am and 3pm, and has the highest global horizontal value. 

If you want to look at the actual weather data, refer to this help item to access that file to review the values:

Also, if you want to enter your own values, there is a special section in the config file to do that.  See my AU presentation from last fall for more information:
