    IEQ Credit 8.2: Daylight and views - views

    Intent

    To provide for the building occupants a connection to the outdoors through the introduction of daylight and views into the regularly occupied areas1 of the building.

    Requirements

    Achieve a direct line of sight to the outdoor environment via vision glazing between 30 inches and 90 inches above the finish floor for building occupants in 90% of all regularly occupied areas by stationary retail staff and/or customers.

    Determine the area with a direct line of sight by totaling the regularly occupied square footage 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 square footage of the office may be counted if 75% or more of the area has a direct line of sight to perimeter vision glazingThe approach used to determine the calculated area of regularly occupied areas with direct line of sight to perimeter vision glazing. The area determination includes full height partitions and other fixed construction prior to installation of furniture.. If less than 75% of the area has a direct line of sight, only the area with the direct line of sight counts toward meeting the credit requirement. For multi-occupant spacesMulti-occupant spaces are places of egress, congregation, or where occupants pursue overlapping or collaborative tasks. Multi occupant spaces may be regularly or non-regularly occupied spaces., the actual square footage with a direct line of sight to perimeter vision glazing is counted.
