[Bldg-sim] Binned weather data for US (not the equest weather file)

True they are 30 years worth of data (a tad longer than 10 years) points with the extremes thrown out but you are using binned data. How accurate of a calculation are you really getting anyway? If one were using bin data I would suggest that throughing out the extremes would be warranted.

The problem with TMY files is that they only have 8760 observations. You should use at least 10 years of actual hourly air temperatures to get a good sample, particularly the extremes.

Or you can easily make your own bin data using TMY3 data files and MS Excel's Histogram function. Works like a charm and the cost is right :) and you can set the bins to match whatever bin size you want. Use some Pivot Table functionality and you can cut those bins down to only occuppied hours etc.

The updated Engineering Weather Data to cover 1973-1996 and put it on a CD

http://ols.nndc.noaa.gov/plolstore/plsql/olstore.prodspecific?prodnum=5005

It is only $17 now.
