Re: [EnergyPlus_Support] Design Day in Weather Data
For basic system sizing, use either the Cooling (DB=>MWB) .4% or 1% dry bulb
design day. The percentage represents the % of time the Dry Bulb temperature
exceeded the design day maximum temperature in the 20-30-year period of record
used to develop the data. The WB (wet-bulb) days can be used for cooling tower
and evaporative cooling applications, and the DP (dew-point) days are used for
applications with humidity control, especially with high ventilation rates.
