Sky component for unglazed horizontal rectangular opening Dsh --
This algorithm gives the sky component (from a CIE overcast sky) on a
horizontal plane directly beneath one corner of the opening.
- Angles a, b, c and d from figure, radians
- To obtain the sky component for a opening with clear 6mm glass, the value
Ds obtained from this algorithm may be multiplied by the transmittance
T obtained from algorithm 2.34.
