Not a direct answer to you question, but perhaps this will save you some
work.<br><br>
ASHRAE did a research project several years ago to compile extreme
weather sequences. I imagine that this would serve your purpose if
the database includes a site that is reasonably close to yours.
These sequences are as long as 7 days. I doubt that you would need
a month of data to generate the maximum cooling load.<br><br>
Design Weather Sequence Viewer CD-ROM<br><br>
Extreme weather sequences were abstracted from existing long-term data
for over 200 U.S. locations and over 100 Canadian locations to create
this CD. Users are provided a summary of the statistics of these
sequences, and the program will select the output of the desired data. On
an hourly basis, 3, 5 and 7 day sequence lengths are identified for high
and low dry-bulb temperature, high enthalpy, high dew-point temperature
and low wet-bulb depression. The sequences correspond to the 0.4, 1 and 2
percent annual frequency of occurrence (equivalent to the 1, 2.5 and 5
percent seasonal frequency of occurrence). <br><br>

University of Kentucky/Donald Colliver was the contractor on that
one. I'd try the high dry bulb and high enthalpy sequences to see
which is worse.<br><br>
Another possibility is to generate synthetic sequences using another
product of ASHRAE research:<br><br>
EXTREMES: Weather Sequence Generator CD-ROM<br><br>
This program synthesizes extreme, but statistically possible, hourly
weather data for periods of up to one week for a specified month and for
over 300 locations in North America, with the capability of modifying or
expanding the data for greater flexibility. Operates under Microsoft
Windows 95/NT operating systems. <br><br>

I'm in the process of putting together a thermal active cooling
simulation<br>
model to be used in residential buildings. I need to run it against
extreme<br>
hot weather data. the problem is this.<br><br>
*-I have weather data spanning 10 years for a given location.<br><br>
*-I need to determine the hottest month or week that will produce
the<br>
largest cooling load.<br><br>
What criteria should I look for as the load is based not only on dry
bulb<br>
temp but also humidity and solar.<br><br>
Is there any sort of CoolingLoad factor algorithm that takes all of
these<br>
into account when sizing cooling systems? Is there a common weighting
factor<br>
used?<br><br>
CoolingLoadFactor(SolarGains, DryBulbTemp, Humidity,... ?) = ?<br><br>
I''l need a criteria to create a program to parse the weather data<br>
to get my extreme week/month.<br><br>
Thanks for your help<br><br>
