[BLDG-SIM] TMY2 weather data for design purpose simulation

[Jeff Haberl]

That's an interesting question. I believe you'll find some useful ASHRAE papers on this topic by such authors as Sandy Klein, Dru Crawlay, Don Colliver and others. AHSRAE's TC 4.2 committee has also studied this. However, most of these consider statistics of peak or extreme weather conditions. I do not recall any papers that considered uncertainty of equipment sizing.

Dear all:
 
I'm looking for information regarding the uncertainty of using TMY2 weather data in the simulation for sizing HVAC equipment. Does anyone know anything about this? Thanks,
