Credit 8.1 (1 point):Achieve a minimum Daylight Facor of 2 percent (excluding all direct sunlight penetration) in 75 percent of the space occupied for critical visual tasks, not including copy rooms, storage areas, mechanical plant rooms, laundry, and other low occupancy support areas.

Credit 8.2 (1 point): Direct line of sight to vision glazing from 90 percent of all regularly occupied spaces, not including copy rooms, storage areas, mechanical, laundry, and other low occupancy support areas.

Large Missile Impact Test

(for windows, doors, skylights, glazing and shutters between grade and 9m (30ft.) above grade)

Three identical test specimens.
Missile is 5 x 10 cm timber weighing 4kg (2in. x 4in.) timber weighing 9lbs.
Two impact points at 15m/sec (50ft./sec.): one at center, one and one within 15.2cm (6in.) of a corner.

All three speciments must survive impacts without penetration before proceeding to cyclic pressure loading.

Small Missile Impact Test

(for windows, doors, skylights, glazing and shutters above 9m (30ft.) above grade)

Three identical test specimens.
Missile is steal sphere weighing 2 gm (0.07 oz.).
30 small missile impacts at 40 m/sec (130 ft./sec):10 at center, 10 at near long edge, 10 near corner.

All three specimens must survive impacts without penetration before proceeding to cyclic pressure loading.

Cyclic Pressure

(applied to all three specimens following large or small missile impact tests; duration of each cycle is 1-3 seconds; all inward-acting pressure cycles are applied first, followed by outward-acting cycles)
