modelFLUXsurfMask
Information
Calculation of solar boundary conditions for the (Lf x Hf)-sized surface considering near and distant mask
Hypothesis and equations
This model relies on the Masks model to estimate effects of near and distant solar masks.
- Shading devices (near mask)
- Horizontal overhang such as awning
- Lateral fin
- Both overhang and lateral fin (such as egg crate)
- Vertical distant masks (such as building)

Instructions for use
none
Known limits / Use precautions
These models are valid only for vertical walls.
The accumulation of several masks of near types for a same wall is prohibited
