This tool is the product of ASHRAE Research Project RP1093. It can be
obtained by contacting ASHRAE's Manager of Research, Mr. Michael Vaughn.
It converts 8760 columnar data into a matrix that allows for accurate
percentiles to be calculated for weekday and weekend. It also
automatically produces the input code text that can be plugged directly
in to DOE-2, BLAST and EnergyPlus.

The ASHRAE papers on this are as follows:
