Achieve a direct line of sight to the outdoors via vision glazing for 80% of all regularly occupied spacesRegularly occupied spaces are areas where one or more individuals normally spend time (more than one hour per person per day on average) seated or standing as they work, study, or perform other focused activities inside a building..

Regularly occupied areas that can be counted toward this credit must meet the following criteria:

In plan view, the area is within sight lines drawn from perimeter vision glazing to provide at least an 11 degree horizontal angle of view to the perimeter vision glazing.

In section view, the area is within sight lines drawn from perimeter vision glazing to provide at least an 11 degree vertical angle of view to the perimeter vision glazing.

The view from each area must include objects at least 50 feet outside the vision glazing, objects lit with daylight that are exposed to direct sunlight or display wind movement, and natural elements (e.g. sky, vegetation, water, people, animals, or other random movement).  

For private offices, the entire square footage of the office may be counted if 80% of the area satisfies the line-of-sight criteria. For other multi-occupant spacesConference rooms, classrooms and other indoor spaces used as a place of congregation for presentations, trainings, etc. Individuals using these spaces share the lighting and temperature controls and they should have, at a minimum, a separate zone with accessible thermostat and an air-flow control. Group multi-occupant spaces do not include open office plans that contain individual workstations., only the actual square footage that satisfies the line-of-sight criteria may be counted.

Lines of sight may be drawn through interior glazing.  Any permanent interior obstructions (e.g. lab hoods, fixed partitions) must be considered as limiting the view angle.  Movable opaque full-height or partial-height partitions must be included in calculations and line-of-sight drawings. 

Fixed window treatments (e.g. ceramic frit patterns, wire meshes, bars, grill-work) in the field of view may compromise the quality of the view.  The project team must submit photographs of the views from the interior spaces to demonstrate that such fixed treatments do not compromise the quality of view.
