To provide building occupants a connection to the outdoors through the introduction of daylight and views into the regularly occupied areas of the building.
Achieve a direct line of sight to the outdoor environment via vision glazing between 30 inches and 90 inches (between 0.8 meters and 2.3 meters) above the finish floor for building occupants in 90% of all regularly occupied areas. Determine the area with a direct line of sight by totaling the regularly occupied floor area that meets the following criteria:
- In plan view, the area is within sight lines drawn from perimeter vision glazing.
- In section view, a direct sight line can be drawn from the area to perimeter vision glazing.
The line of sight may be drawn through interior glazing. For private offices, the entire floor area of the office may be counted if 75% or more of the area has a direct line of sight to perimeter vision glazing. For multi-occupant spaces, the actual floor area with a direct line of sight to perimeter vision glazing is counted.
