Non-Opaque Venetian Blind +90 Calculation Error
Tuesday, September 5, 2017
Calculating a Venetian blind with the following characteristics will result in an incorrect answer:
- Slat material is not opaque (transmittance front and back, visible and solar > 0)
- Slats tilt angle = +90
- Slat spacing > slat width (so that there is space between the slats in the vertical (+90) position)
Solution: model this case with tilt set to either -90 or +89 and the result will be correct.
