Screen Beam-Beam Solar Transmittance

Type: real number
The beam-beam transmittance of the screen material at normal incidence. This input field is the same as the material openness area fraction and can be autocalculated from the wire spacing and wire and diameter. Assumed to be the same for both sides of the screen.
Unit: dimensionless
Minimum: 0
Default: autocalculate

Screen Beam-Diffuse Solar Transmittance

Type: real number
The beam-diffuse solar transmittance of the screen material at normal incidence averaged over the entire spectrum of solar radiation. Assumed to be the same for both sides of the screen.
Unit: dimensionless
Minimum: 0

Screen Beam-Diffuse Solar Reflectance

Type: real number
The beam-diffuse solar reflectance of the screen material at normal incidence averaged over the entire spectrum of solar radiation. Assumed to be the same for both sides of the screen.
Unit: dimensionless
Minimum: 0

Screen Beam-Beam Visible Transmittance

Type: real number
The beam-beam visible transmittance of the screen material at normal incidence averaged over the visible spectrum range of solar radiation. Assumed to be the same for both sides of the screen.
Unit: dimensionless
Minimum: 0

Screen Beam-Diffuse Visible Transmittance

Type: real number
The beam-diffuse visible transmittance of the screen material at normal incidence averaged over the visible spectrum range of solar radiation. Assumed to be the same for both sides of the screen.
Unit: dimensionless
Minimum: 0

Screen Beam-Diffuse Visible Reflectance

Type: real number
