WeatherBus

Weather data and solar position (source side)

FastSmoothBuildings.Interfaces.WeatherBus, connector (source)

Purpose

Source side of the weather: all variables are outputs (signals, no flow variable).

  • weather data: TDryBul and TBlaSky (K), winSpe (m/s), winDir (rad, 0 for a wind from the north), the irradiances HDirNor, HDifHor and HGloHor (W/m2), the atmospheric pressure pAtm (Pa);
  • solar position: the latitude lat, the declination decAng and the hour angle solHouAng (rad), the cosine of the zenith angle cosZen;
  • the circumsolar and horizon brightening coefficients F1 and F2 of the Perez model of the diffuse irradiance on a tilted surface.

Use

The output of BoundaryConditions.Weather, which computes the solar position and the Perez coefficients once for the site; connect it to the WeatherBusIn of the zones and the other components. A zone forwards its weather to its surfaces through the wea of its ZoneSurfaceBus, a WeatherBus.
