Which cooling design day is most common for sizing rooftop units?
The energyplus weather file has 12 design-days for cooling. One of the variables is 0.4%, 1%, and 2% - I am assuming 0.4% is the most common for hvac-sizing. Not clear on which one of the following is more common - DB=>MWB, WB=>MDB, DP=>MDB, Enth=>MDB. I am guessing DB=>MWB is most common but would like to confirm. When does it make sense to use one or the other. Does anyone use the latent load related design-days on actual projects? Thanks.
