Re: [EnergyPlus_Support] Does EnergyPlus accept multi-year weather files with arbitrary begin and end dates? [1 Attachment]



The csv outputs will be that way.  as you have described.

I am unsure how the tabular results will show.  From the attached it looks like it will sum them all.  Not sure what would happen if you asked for tabular monthly reports.

I can also send you the weather file that created this one -- it's a bit of a manual process to create the weather file -- the weather converter can't do it.  It's only a two year (so I could show a leap year day)

Answer is yes -- read about:
RunPeriod:CustomRange

Tabulated results -- tabular will sum them all, they will be presented in csv reports sequentially.
Does that mean if the run period were from July 15, 2012 through July 14, 2013, the tabulated results would be :

July (2012) partial
Aug (2012) full
...
Dec (2012) full
Jan (2013) full
...
July (2013) partial

?

My experience is no.  to do a winter model with actual weather data I have to make a file with January to June as the second year and September to December as the first year and then I can run a heating season model of October to May.

Subject: [EnergyPlus_Support] Does EnergyPlus accept multi-year weather files with arbitrary begin and end dates?
 
 

I suppose I can find the answers by doing some test runs, but I thought I'd ask and see if
anyone knows the answer to the question posed in my subject line.

If EnergyPlus can accept multi-year weather files, e.g., one that goes from July 15, 2011
through July 14, 2013, how would the monthly results be tabulated ?

Joe
