Hourly weather data

Select the hourly weather data from the list of Hourly weather data components. These components reference the epw file that will be actually used in the simulation.

 

DesignBuilder uses EnergyPlus epw format hourly weather data for simulations (heating and cooling design calculations use much simpler design weather data).

 

You can review, edit and convert weather using the Edit hourly weather data dialog.

 

You can also add your own hourly weather data.
