Figure 4-3. Example of architectural shading devices.
4-6.1
Considerations for orienting glazing:
Orient building to maximize north and south exposures.
North facing windows provide the most even illumination.
If orientation is off-axis from north and south, provide shading devices for
south-east and south-west exposures.
Provide architectural shading devices for south orientations.
Provide manual shading devices for south orientations. Horizontal blinds
best control the high angle light on southern exposures.
Provide manual shading devices for east and west orientations. Vertical
blinds best control the low angle light on east and west exposures.

GLAZING CHARACTERISTICS. Use selective glazing to optimize and tune
glass based on its purpose and use (clerestory or vision). Clerestory glass may require
high visibility transmittance without color distortion while minimizing infrared penetration.
4-7.1
Considerations for glazing characteristics:
for clerestories and other daylight fenestrations.
Although the visible transmittance selected depends on personal
preference, typically, use Tvis values in the medium range for view
windows (.40 or greater).
