Light Pollution Reduction - 1 Point
Commercial Interiors - Sustainable Sites
Intent
- To minimize light trespass from the building and site, reduce
sky-glow to increase night sky access, improve nighttime visibility
through glare reduction and reduce development impact from lighting on
nocturnal environments.
Requirements
A
building whose nonemergency interior luminaires with a direct line of
sight to any openings in the envelope (translucent or transparent) must
have their input power reduced (by automatic device) by at least 50%
between 11 p.m. and 5 a.m. After-hours override may be provided by a
manual or occupant-sensing device provided the override lasts no more
than 30 minutes.
OR
A
building whose openings in the envelope (translucent or transparent)
with a direct line of sight to any nonemergency luminaires must have
shielding (with transmittance of less than 10%) that is controlled or
closed by automatic device between 11 p.m. and 5 a.m.
Referenced Standards
None
Design Strategies
During
the building selection process, give preference to those properties
which exhibit green building strategies and technologies.
