APPENDIX
M
Mandatory measures checklist:
A form used by the building plan
checker and field inspector to
verify a building’s compliance with
the prescribed list of mandatory
features, equipment efficiencies
and product certification
requirements. The documentation
author indicates compliance by
initialing, checking or marking N / A
(for not applicable) in the boxes or
spaces provided for the designer.
Metal halide (MH): A highintensity
discharge (HID) light
source commonly used in retail,
industrial and outdoor applications.
MH lamps use a mixture of argon,
mercury and metal halide. A hard
outer glass covering absorbs
much of the UV radiation emitted
by MH lamps, thereby reducing
their efficacy. MH lamps have
CRI ratings of 60. Full light output
takes about 2 – 10 minutes,
making them less compatible with
adaptive lighting controls. MH
lamps produce more light than
mercury vapor lamps and provide
better color rendering, with CRI
ratings of 60 – 96.
Motion sensor: A device that
automatically turns lights OFF soon
after an area is vacated. Motion
sensor applies to outdoor lighting
controls. When the device is used
to control indoor lighting systems,
it is called an occupant sensor,
occupancy sensor, occupantsensing
device, or vacancy sensor.
Multi-level lighting control: A
lighting control device that reduces
power going to a lighting system,
and the consequent light output
of the system, in multiple discrete
steps.
Multi-scene lighting control:
In addition to all-OFF, this feature
allows end-users to program
or select pre-defined lighting
settings for two or more groups of
luminaires for multiple activities or
displays within a space.
O
Occupant sensor: A device that
automatically turns lights OFF
soon after an area is vacated. The
term occupant sensor applies to a
device that controls indoor lighting
systems. It is called a motion
sensor when used to control
outdoor lighting systems.
P
Pendant: A type of ceilingmounted
luminaire that is
suspended from the ceiling, often
above task surfaces.
Permanently installed lighting:
All luminaires attached to the
inside or outside of a building site,
including: track and flexible lighting
systems; lighting attached to
walls, ceilings, or columns; inside
or outside of permanently installed
cabinets; internally illuminated
case work; lighting mounted on
poles, in trees, or in the ground;
and lighting attached to ceiling
fans and integral to exhaust fans
other than exhaust hoods for
cooking equipment. Portable
lighting and lighting installed in
appliances by the manufacturer
is not considered permanently
installed lighting.
Photocontrol: An electrical
device that detects changes in
illumination levels and controls
lighting load at predetermined
illumination levels. Automatically
turns luminaires ON at dusk and
turns OFF at dawn.
Pin-base luminaire: A luminaire,
or fixture, that accepts lamps with
a pin base, as opposed to a screw
base. GU-24 pin-base luminaires
prevent the use of low-efficacy
lamps in high-efficacy luminaires.
Portable lighting: Lighting with
plug-in connections for electric
power, including: table lamps
and freestanding floor lamps,
lighting attached to modular
furniture, workstation task lights,
lights attached to workstation
panels, movable displays, and
other equipment that is not
permanently installed lighting.
R
Readily accessible: Capable
of being reached quickly for
operation, repair or inspection.
Readily accessible items must
be accessible without the use of
special equipment, removal of
obstacles or need for climbing.
S
Screw-base luminaire: A
luminaire, or fixture, with a socket
that accepts screw-base lamps
(e.g., incandescent, CFL or LED
replacement lamps). Screw-base
luminaires are considered lowefficacy
under Title 24, Part 6
because they are compatible with
low-efficacy lamps.
Skylight: A window (fenestration
surface) installed in a roof and
having a slope of less than 60
degrees from the horizontal plane.
