Hi,all, i need weather profile to test the solar air heater's performance in summer.i know energy plus provide the typical year' s weather profile, but if i use the whole summer weather file to test the solar air heater's performance, the computation take quite a long time. So i want to know whether there is a typical summer day weather profile for a specified plate so that i can use one day's weather data to do the sumulation representing the whole summer period. i noticed energy plus provide designday condition profile which is ddy type profile. I am not sure this file can be used as typical day used in my simulation. and furtherly, in the ddy profile, for the summer design day, they have 5 or 7 conditions can be choosen, so which one i should choose. thanks
