Re: [EnergyPlus_Support] How to create a DDY from epw

[Linda Lawrie <linda@xxxxxxxxxxxxxx>]

They do not contain DDY files because their locations/WMO# are not in the ASHRAE dataset.

You can download the full set of ASHRAE DDY design conditions (both annual and monthly are available) from the helpdesk and select a location that is "near".  Or you can look at the .stat file which will have the "design conditions" listed  (from the weather data) at the top of the file.

e.g., For Huesca:

 - Displaying Design Conditions calculated from this weather file.
 -  The following design temperature statistics are calculated based on THIS weather file ONLY
 -  and may not be representative of a long-term  period of record normally used for
 -  design temperatures. Also, note that dew point temperatures are listed where
 -  wet-bulb temperatures are normally presented.

        Design Stat     Coldest Month   HDB 99.6%       HDB 99%
            Units            {}             {C}            {C} 
          Heating       12        -1.2    -0.7

        Design Stat     Hottest Month   CDB .4% CDB 1%  CDB 2%  CDP .4% CDP 1%  CDP 2%
            Units            {}            {C}     {C}     {C}     {C}     {C}     {C}
          Cooling        8       34.0    32.9    31.8    14.9    14.7    14.4

        Design Stat     Jan      Feb      Mar      Apr      May      Jun      Jul      Aug      Sep      Oct      Nov      Dec
            Units        {m/s}    {m/s}    {m/s}   {m/s}    {m/s}    {m/s}   {m/s}    {m/s}    {m/s}   {m/s}    {m/s}   {m/s}
