SyntheticWeather¶
Clear days: a daily cycle of the outdoor temperature, the sun from the solar position
FastSmoothBuildings.Examples.BaseClasses.SyntheticWeather, model (source)
The weather of clear days, without a weather file: the outdoor temperature follows a sine around
TMea, warmest at 15:00; the direct irradiance is on while the sun is above the horizon (a smooth step
of the cosine of the zenith angle computed by
BoundaryConditions.Weather), the
diffuse and global irradiances follow the cosine of the zenith angle.
