Create a custom EPW object from a location and data collections of annual hourly data.

Inputs

  • location [Required]

    A location object for the epw_file.

  • dry_bulb_temp

    Annual hourly data collection for dry bulb temperature [C]

  • dew_point_temp

    Annual hourly data collection for dew point temperature [C]

  • wind_speed

    Annual hourly data collection for wind speed [m/s]

  • wind_direction

    Annual hourly data collection for wind direction [degrees]

  • direct_normal_rad

    Annual hourly data collection for direct normal radiation [Wh/m2] or [W/m2]

  • diffuse_horiz_rad

    Annual hourly data collection for diffuse horizontal radiation [Wh/m2] or [W/m2]

  • horiz_infrared_rad

    Annual hourly data collection for horizontal infrared radiation intensity [Wh/m2] or [W/m2]

  • direct_normal_ill

    Annual hourly data collection for direct normal illuminance [lux]

  • diffuse_horiz_ill

    Annual hourly data collection for diffuse horizontal illuminance [lux]

  • total_sky_cover

    Annual hourly data collection for the fraction for total sky cover [tenths]

  • atmos_pressure

    Annual hourly data collection for weather station pressure [Pa]

  • visibility

    Annual hourly data collection for visibility [km]

  • ceiling_height

    Annual hourly data collection for cloud ceiling height [m]

  • model_year

    Annual hourly data collection for the year from which the hourly data has been extracted. This input is necessary when the input data collections are from a leap year.

  • base_epw

    File path to an optional .epw to fill empty slots for data that has not been connected here.

  • run [Required]

    Set to True to run the component and create the epw_obj.

Outputs

  • report

    Reports, errors, warnings, etc.

  • epw_obj

    An EPW object that can be written to a file using the Write EPW component.
