EnergyPlus is an energy simulation software which models heating, cooling, lighting, ventilating, and other energy flows as well as water in buildings.
EnergyPlus has its own weather file format which can be read from windRose PRO. EnergyPlus weather files (*.epw) are available for hundreds of points around the world, and can be downloaded from the US Department of Energy website.
After loading the data, the total number of data and the total number of valid data, together with the percentage, appear in the lower right corner of the main mask. The number of valid data is determined using the
filtering options specified by the user.
WindRose PRO allows to apply date and time filtering on the wind speed and direction loaded from the EnergyPlus Weather data. Since the year of data can vary arbitrarily for each month within the EPW data, filtering on years is not allowed.
