An emergency veterinary office located in a strip mall will be open 24 hours a day. What must the project team do reduce light trespass from the facility?

A: Reduce input power of all nonemergency interior luminaires with direct line to any openings by 50% between 11 p.m. and 5 a.m.
B: Install no fixture lumens that are emitted at an angle of 90 degrees or higher from nadir
C: Design all luminaires a maximum initial luminance less than 0.01 horizontal and vertical footcandles 20 ft. beyond building
D: Install automatically controlled shielding that closes from 11 p.m. to 5 a.m.

参考答案: D

本题解释:
Light trespass reduction is part of Sustainable Sites Credit, Site Selection, Option 2, Path 6: Light Pollution Reduction.

If a facility is open 24 hours a day the project must use Option 2 and cannot choose Option 1.

For Option 2 all exterior openings must have automatically controlled shielding that closes from 11 p.m. to 5 a.m. If automatic shades are used they must have less than 10% transmittance.
