Information

Model for the convective heat balance of a shade that is in the outside or the room-side of a window.

The convective heat balance is based on the model described by Wright (2008), which can be shown as a convective heat resistance model as follows:

Wright (2008) reports that if the shading layer is far enough from the window, the boundary layers associated with each surface will not interfere with each other. In this case, it is reasonable to consider each surface on an individual basis by setting the convective heat transfer coefficient shown in grey to zero, and setting the black depicted convective heat transfer coefficients to h=4 W/m2 K. In the here implemented model, the grey depicted convective heat transfer coefficient is set set to h' = k   h, where 0 ≤ k ≤ 1 is a parameter.
