Dear ARE community,
I am attaching two images, one from Lechner, and one from Ching. Each has a different criteria for what constitutes an ideal shading device based on orientation. In a nutshell they say the following:
Horizontal Overhang for South, East and West
Vertical fins for North, and
Vertical fin slated for East and West (although this last option is not recommended).
Horizontal overhangs for South
Vertical louvers most effective for Eastern and Western exposures, and
No mention of Northern orientations.
Can anyone clarify what the correct answer would be?
I greatly appreciate it!
