Daylight Simulation Model Create a daylight simulation model for the building, or regularly occupied space with glazing.  This model should include the appropriate glazing factors as well as representative ________ settings for interior finishes.
surface reflectance
For each applicable room/area, include a horizontal grid at ___ above the floor.  The grid will represent the typical workplane height.

30 inches
The calculation grid should be set at approximately _____ intervals to provide a detailed illumination diagram for each area.
2 foot
Calculate the daylight illumination for each applicable space using the following daylight criteria;
sky conditions at 12 noon on the equinox March 21/September 21 for the project’s specific geographic location.
If the minimum illumination for a room/area is 25 footcandles or greater then the:
square footage of the room/area is applicable for this credit.

The portion of the room with a 2% or higher daylight factor or _________ minimum illumination would count towards the percentage of all space occupied for critical visual tasks.
25 footcandles
Visible Light Transmittance (Tvis)
is the ratio of toal trasmitted light to total incident light. In other words, it is the amount of visible spectrum light passing through a glazing surface divided by the amount of light striking the glazing surface.;
A higher Tvis value indicates:
that a greater amount of visible spectrum incident light is passing through the glazing.

Achieve a direct line-of-sight to the outdoor environment (glazing between _________) for building occupants in 90% of all regularly occupied areas.
2′-6" and 7′-6;
In section view, a direct sight line can be drawn from a point _______, above the floor to perimeter vision glazing.

For private offices, the entire sf of the office can be counted if ____ or more of the area has direct line of sight to perimter vision glazing.
If less than ____ of the area has direct line of sight then only the area with the direct line of sight will be; counted towards meeting the credit requirement not the whole office.
For multi-occupant spaces, the actual square footage ________ is counted.
with direct line of sight to perimeter vision glazing.
Direct Line of Sight to Perimeter Glazing
is the 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.
Horizontal View at 42 inches
is the approach used to confirm that the direct line of sight to perimeter vision glazing remains avaliable from a seated position.; It uses section drawings that include the installed furniture to make the determination
vision glazing
