functionFullMask
Calculation of the sunny area for the full mask (horizontal+vertical)
Information
Calculation of the sunny share of a surface considering shading devices
Hypothesis and equations
Shading devices (near mask) with both overhang and lateral fin (such as egg crate) are considered. See diagram below:
Bibliography
ISO 13791 standard
RT2012 standard for the consideration of vertical distant masks
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
Validations
