.Buildings.HeatTransfer.Windows.SideFins

Information

For a window with side fins, this model outputs the fraction of the area that is exposed to the sun. The model calculates the fraction of the window area that is exposed to the sun. The side fins are symmetrically placed above the vertical window centerline, and its height must be equal or greater than the window height. This models can also be used for doors with side fins. The figure below shows the parameters. The parameter h is measured from the top of the window to the top of the side fins. Side fins are assumed to extend at least to the lower edge of the window. (Any portion of the side fin below the window edge does not cast as shadow on the window anyway.)
