G-52 July 1, 1999 Residential Manual
In the summer months, the mass material
can be cooled down at night by natural
ventilation. During the daytime, the mass
absorbs excess heat and helps keep down
indoor air temperatures. If glazing is well
shaded to keep out direct sunlight, the mass
can substantially reduce or eliminate
completely the need for mechanical cooling.
The standards specify thermal mass materials
as including, but not limited to:
• Hard -surfaced slab floors
• Masonry walls and fireplaces
• Gypsum board walls and ceilings in excess
of 1/2 inch thickness
The physical 'properties of thermal mass
materials are listed in Table G-12.
Table G-13 lists recommendations on when it is
appropriate to take credit for a particular mass
material. The intent of these guidelines is to
prevent taking thermal mass credit for floor
materials that are likely to be covered with
carpeting at the time of building occupancy.
Building officials should allow flexibility for
building designs that include radiant floor
heating systems and/or that incorporate large
areas of uncarpeted slabs in conjunction with
south facing glazing as an integral component of
deliberately designed passive solar structures.

Btu/(hr x ft2 x °F), including air film resistances at
both surfaces." [EES, Section 101 ]
The standard U -values listed in Tables G-12
through G-15 must be used for wood frame
assemblies unless a Form 3R is completed as
explained under R -value. Appendix H contains
completed Form 3Rs for each standard

assembly. If insulation level and framing material
are known, but no other information is available
on the assembly, use the worst case (highest)
standard U -value for the insulation level. For
"wall and roof/ceiling assemblies, this

Inspection
The lighting in the kitchen, either general or the
only lighting, must:
• Be fluorescent or another product that has at
least 40 lumens/watt (see Table 2-2).
• Provide a uniform pattern of lighting, such as
a fixture in the center of the kitchen or around
the perimeter (not a fixture in the corner).
• Provide a light level sufficient for performing
basic kitchen tasks such as preparing meals
and washing dishes.
• Be controlled on a readily accessible switch
at an entrance to the kitchen (not in a cup-
board or beside the kitchen sink).
• Be switched separately from incandescent
lighting and on a control panel at an entrance
to the kitchen.
• Not contain medium -base incandescent lamp
sockets. This prevents the occupant from re-
placing the efficient light source with an in-
candescent bulb.

2 Halogen capsule incandescent lamps may be the most efficient light source for highlighting applications.
Most halogen lamps are designed to produce a beam of directed light. Manufacturer's data typically list
the "candlepower" intensity of that beam, rather than lumens (lumens measure total light output in all di-
rections).
3 A new technology using infrared reflecting films on the halogen capsules has increased output up to 30
lumens/watt for some high wattage lamps.
Efficacy of fluorescent lighting varies depending on lamp and ballast types.

�i Kitchen Lighting
Would one fluorescent light in a kitchen,
Installed over the sink or under one.. cabinet,
meet the: "general lighting" requirements?
No. The general lighting must evenly light. the
entire kitchen. Two examples of acceptable
lighting configurations are (1) fluorescent lighting
(or other light source. with at, least 404umens/watt)
around the perimeter of the kitchen (under orover
cabinets),. or (2) a fluorescent in the. center of: the
.kitchen.
If a customer asks me hot.to install fluorescent
lights in their home, are there any other light
sources 1 can use to meet the: kitchen lighting
requirements?
Yes, although they may not be readily available,
there are products other than fluorescent- which
meet the lighting requirements of the standards;
Section 150(k). The two criteria for the kitchen and
bathroom general lighting are (1) a lamp with an
efficacy of 40 lumens/watt or more, and (2) the
fixtures cannot contain a medium base
incandescent lamp socket. Table 2-2 indicates the
typical lumens/watt of several common products,
some of which meet the required lumens/watt.
Specifications from a product's manufacturer can
also be used to verify that a product has at least
40 lumens/watt.
Bathroom Lighting (Section

2. Each room containing a shower or bathtub
shall have at least one luminaire with lamp(s)
with an efficacy of 40 lumens per watt or
greater. If there is more than one luminaire in
the room, the high efficacy luminaire shall be
switched at an entrance to the room.
ALTERNATIVE to Section 150(k)2.: A high
efficacy luminaire need not be installed in a
bathroom if*
B. All luminaires permanently mounted to
the residence providing outdoor lighting
shall be installed with the following
characteristics:
(1) Luminaires with lamps with 40
lumens per watt or greater, or
(2) Luminaires with lamps with an
efficacy of less than 40 lumens per
watt shall be equipped with a
motion sensor.
Note: When using this alternative for multiple
bathrooms, after complying with B. for the
first bathroom, each additional bathroom in
which a high efficacy luminaire is not installed
must comply with A. alone.
3. Luminaires installed to meet the 40 lumens
per watt requirements of Section 150(k) 1. or
2. shall not contain medium base
incandescent lamp sockets, and shall be on
separate switches from any incandescent
lighting.
' Bathroom Lighting
Construction
Each room with a shower or bathtub must have at
least one luminaire with lamps with an efficacy of
at least 40 lumens/watt.
If there is more than one luminaire in the room, the
high -efficacy luminaire must be switched at an
entrance to the room.
As an alternative, both of the following are re-
quired:
1. A luminaire with 40 lumens/watt lamps must
be installed in another room with utilitarian
functions such as a laundry room, utility room
or garage; and
2. All permanently mounted outside lighting must
either be at least 40 lumens/watt or equipped
with a motion sensor.
When using this alternative for two or more rooms
A. A luminaire with lamps with an efficacy with showers or bathtubs, compliance with item 1.
of 40 lumens per watt or greater is above is sufficient for the second or third rooms
installed in a utility room, laundry room, since the outside lighting is already in compliance
or garage; and with item 2 above.
Mandatory Measures July 1, 1999 2-49
Luminaires installed to meet the 40 lumens/watt
requirements cannot contain medium base incan-
descent lamp sockets, and must be on separate
switches from incandescent lighting.
Incandescent lighting fixtures recessed into insu-
lated ceilings must be approved for zero -clearance
insulation cover (IC -rated) in compliance with
Section 150(k)4 (see below).
Installing energy-efficient lamps and fixtures can
reduce lighting energy costs without sacrificing the
quality or quantity of light available. As indicated in
Table 2-2, a 40 watt standard fluorescent lamp is
over four times as efficient as a 100 watt standard
incandescent lamp.
Bathroom Lighting
Inspection .,
Each room with a shower or bathtub (no require-
ment in a half -bath) must have at least one lumi-
naire with lamps with an efficacy of at least 40 lu-
mens/watt, which may be fluorescent or another
efficient technology (see Table 2-2 above).
When there is more than one luminaire in the
room, the high -efficacy luminaire (greater than or
equal to 40 lumens/watt) must be switched at an
entrance to the room.
As an alternative, both of the following are re-
quired:
1. A luminaire with 40 lumens/watt lamps must
be installed in a laundry room, utility room or
garage; and
2. All permanently mounted outside lighting must
either be at least 40 lumens/watt or equipped
with a motion sensor.
Luminaires installed to meet the 40 lumens/watt
requirements cannot contain medium base incan-
descent lamp sockets, and must be on separate
switches from incandescent lighting.
Incandescent lighting fixtures recessed into insu-
lated ceilings must be IC -rated incompliance with
