Hello Group...

I'm in the process of putting together a thermal active cooling simulation
model to be used in residential buildings. I need to run it against extreme
hot weather data. the problem is this.

*-I have weather data spanning 10 years for a given location.

*-I need to determine the hottest month or week that will produce the
largest cooling load.

What criteria should I look for as the load is based not only on dry bulb
temp but also humidity and solar.

Is there any sort of CoolingLoad factor algorithm that takes all of these
into account when sizing cooling systems? Is there a common weighting factor

CoolingLoadFactor(SolarGains, DryBulbTemp, Humidity,... ?) = ?

I''l need a criteria to create a program to parse the weather data
to get my extreme week/month.

Thanks for your help
