2. Lecture Notes
Lighting and Appliances
Anything that draws electrical power is referred to as a load.
Part of weatherizing a home includes minimizing the loads in
the home in order to lower energy bills and maximize energy
efficiency.
Artificial Lighting
Artificial lighting is provided by electricity, fixtures, and
bulbs. Artificial lighting is a big contributor to high energy
costs. It can contribute as much as 50 percent of the total
energy costs of a home.
Lynn Clement of Focus on Energy once said, “If every
American household replaces light bulbs in their five most
frequently used fixtures with ENERGY STAR compact
fluorescent bulbs, we could save more than $8 billion in annual
energy costs and prevent greenhouse gases equal to the
emissions of more than 10 million cars.”
Since lighting accounts for 20 to 25 percent of U.S. energy
consumption, the move to more energy efficient lighting is very
important.
Types of Lighting
There are three primary uses, or functions, for lighting in
homes: task, ambient, and accent. Task lighting provides light
to perform work. Ambient lighting may include light that is
used for work but also includes lighting for safety and security.
Any lighting used for contrast or ambiance is accent lighting.
There are many different types of artificial lights available for
residential uses.
Types of Artificial Lighting
Incandescent

3. Fluorescent
Compact fluorescent
High-intensity discharge
Halogen
Light Emitting diodes
Full Spectrum
Recessed Lights
Incandescent Bulbs
Incandescent bulbs, which are also referred to as A-type bulbs,
are the oldest, most prevalent, and least expensive type of
lighting. Incandescent bulbs function by allowing an electric
current to pass through a thin filament and heat it until it
produces light. The enclosing glass bulb prevents oxygen from
reaching the filament because oxidation would destroy it.
An incandescent light bulb
Unfortunately, incandescent bulbs are the most inefficient type
of bulb available by far. Only 10 percent of the energy used by
an incandescent bulb is actually converted to light. The other
ninety percent of the energy emitted by incandescent light bulbs
is in the form of heat. The average life for one of these
commonly sold bulbs is usually between 1,500 and 2,000 hours.
However, there are some long-life bulbs manufactured today.
A house that is full of incandescent light bulbs will require that
the air conditioner work constantly to keep the temperature
down. There are movements throughout the United States to
discontinue the sale and use of these light bulbs because of their
extreme inefficiency.
Fluorescent Bulbs
Fluorescent bulbs have been employed for both residential and
commercial use for many years. The original 4- and 8-foot
long, round tubes were termed T-12s and were about an inch
and a half in diameter. Newer and more efficient T-8 tubes are
only an inch in diameter. The newest T-5 bulbs are even
smaller than the T-8s. The 4-foot tubes are normally 40-watt
and the 8-foot tubes are normally 75-watt.

4. Compact Fluorescent Bulbs
CFLs come in two types: pin type and screw-in. Pin type
compact fluorescents require a converter or the replacement of
the lighting fixture before they can be installed. Screw-in
compact fluorescents are made to replace incandescent bulbs in
almost any normal light fixture. CFLs come in all types of
bulbs including lamps, reflectors, candelabras, and outdoor
bulbs, and some are even dimmable. The most common CFLs
found in almost all stores are spiral, screw-in bulbs.
A screw-in compact fluorescent light bulb
When creating a more efficient lighting scheme for a home, the
weatherization service provider should consider using compact
fluorescent light bulbs (CFLs). CFLs are the most energy
efficient type of bulb available and are becoming the bulb of
choice for the replacement of incandescent bulbs when tubes
cannot be used. Exchanging incandescent bulbs for CFLs is one
of the easiest ways to weatherize the lighting in a home.
Compact fluorescent bulbs use less power, have a longer life,
and are more expensive than incandescent bulbs. However,
because of their longer life span, which is about 10 times longer
than an incandescent bulb’s life span, CFLs save in energy
costs.
Effects of Compact Fluorescent Bulbs
Produce 75 percent less heat and cut costs associated with
cooling the home
Use less energy and last longer
Save money on energy costs
A typical 100-watt incandescent bulb can be replaced by a 25-
26 watt CFL, which will fit easily into almost all lamps and
light fixtures in today’s homes. A weatherization service
provider can find replacement CFLs that provide the same color
of light and the same amount of light while using three to four
times less energy than an incandescent bulb. This cuts the
lighting costs of a residence by about 75 percent.
Some CFLs still take a few seconds to warm up before they

5. reach full brightness. The weatherization service provider
should be familiar with these bulbs when he or she installs them
and should consult the homeowner as to whether he or she
minds the warm up period.
There are certain places in the home that are ideal for the use of
compact fluorescent bulbs.
Ideal Rooms for CFLs
Family room
Living room
Kitchen
Dining room
Bedrooms
Outdoor lighting
One disadvantage of CFLs is that they do contain a small
amount of mercury and should be recycled. Also, some caution
should be taken if a bulb is dropped and manufacturer’s
recommendation should be referenced.
High-Intensity Discharge Lamps
High-intensity discharge lamps have the highest efficacy and
are the longest lasting of any type of bulb. Efficacy is the
number of lumens or light output produced per watt of
electricity used. These lamps save between 75 percent and 90
percent of energy costs compared to incandescent bulbs.
Mercury vapor lamps are the oldest type of high-intensity
discharge lamp. Lamps that provide 50 lumens per watt have
been primarily used for street lighting.
Metal halide lamps are similar in construction to mercury vapor
lamps but have a higher light output, more lumens per watt, and
better color. These bulbs are used for indoor lighting in gyms,
sports arenas, convention centers and other similar types of
buildings, and outdoor applications.
High-pressure sodium lamps are also a type of high-intensity
discharge lighting. These lamps provide 90 to 150 lumens per
watt and are becoming very popular for outdoor lighting
because they provide a warm, white light. However, they do not
provide exceptional color rendition.

6. A weatherization service provider can replace older mercury
vapor lights with metal halide or high-pressure sodium lamps in
order to achieve better energy efficiency.
Halogen
A halogen light bulb is actually an incandescent light with a
tungsten filament that is sealed into a compact transparent
envelope. The envelope is filled with an inert gas and halogen.
The halogen increases the life span of the bulb to twice the life
span of an incandescent lamp.
Light Emitting Diodes
A light emitting diode (LED) is an electronic light source that
works based on a semiconductor diode. When an LED is on,
electrons combine with holes and light energy is released.
These lamps offer many advantages over other, older light
sources including lower energy consumption, longer life span,
greater strength, compact size, and faster switching. LEDs are
more expensive and require more current and heat management
than other light bulbs.
Full-Spectrum
Full spectrum bulbs span the electromagnetic spectrum from
infrared to near-ultraviolet and are meant to simulate natural
light. These bulbs can be compact or tube fluorescent,
incandescent, or halogen.
Recessed Lights
If recessed lights are installed in a ceiling with a below-grade
space behind it, such as an attic, use only Underwriters
Laboratory (UL) approved fixtures that are airtight, are
Insulation Contact (IC) rated, and meet American Society for
Testing and Materials (ASTM) E283 requirements. This helps
minimize air leakage that can raise energy costs.
Lighting Controls
Regardless of the implemented lighting strategies, using
lighting controls is important for reducing energy costs and
increasing comfort. Lighting controls include occupancy
sensors and timers that save energy and money. Lighting
controls help provide the amount of light that is needed, where

7. it is needed, and when it is needed. A weatherization service
provider can use lighting controls everywhere in a home to
minimize the cost of providing lighting.
There are several lighting control systems that are designed to
maximize lighting.
Lighting Control Systems
Timers are programmable systems that can turn lights on or off
at specific times.
Infrared sensors detect human body heat and can turn lights on
and off as people enter or leave the sensor’s control area.
Daylight sensors turn light on and off based on whether or not
natural light is available.
Motion detectors, photo sensors, and timers should be used as
lighting controls in less frequently used areas of the house.
Light Use
When examining the lighting scheme in a home, the
weatherization service provider should note places where light
trespass and light pollution occur and make adjustments to
minimize or completely remove these instances of waste. Light
trespass occurs when landscape and building lighting fall onto
neighboring buildings and land. Not only is this energy
inefficient, it detracts from the quality of life for neighbors and
may adversely affect wildlife.
Light pollution occurs over urban areas and prevents people
from viewing the night sky. Light pollution in Los Angeles is
particularly problematic, although the negative effects are more
psychological than physical. All the light that is visible in the
nighttime cityscape may be beautiful, but it equals wasted
energy.
Daylighting
In addition to maximizing the energy efficiency of a home’s
artificial lighting scheme, a weatherization service provider
may incorporate some aspects of daylighting into a project.
Daylighting is the practice of placing windows, other openings,
and reflective surfaces so that natural light provides effective
internal illumination. Natural light is provided by the sun. The

8. goal of using daylighting is to maximize visual comfort and
reduce energy usage.
The use of daylighting increases property values and saves
money in the long run. Not only does daylighting reduce the
lighting load, but humans are healthier and happier in natural
light.
Example: On a partly cloudy day, a room illuminated with
natural light gets brighter or darker as a result of the moving
cloud cover. Research has shown that humans respond
favorably to this dynamic because it makes them feel like they
are outdoors.
In schools, studies have shown that test scores are higher for
students who learn in an environment that includes natural
light. In commercial facilities, employees report less stress and
show better workplace performance in an environment that
includes natural light.
It is important to consider that the installation of some
daylighting elements, such as windows, is expensive. In
addition, although daylighting lessens the lighting load, it may
increase the cooling load and, thus, fail to reduce costs.
Common Ways to Provide Daylighting
Windows
Skylights
Awnings and shades
Solar light tubes
Fiber optics
Windows
Windows and their capacity to let hot and cold air into a room
were discussed in Module 4, so they will only be discussed
briefly here. Windows are the most common method used to
allow natural light to come into an interior space. One
drawback of using windows is the fact that they do allow
penetration of outside air and the escape of conditioned air.
Skylights
Skylights are unique in the world of illumination. A skylight is
basically a hole in the roof. Skylights allow natural lighting

9. into an interior room without compromising the privacy of the
building’s occupants. Windows, on the other hand, allow
natural light to flood into a house and they allow people to see
through the window into the building.
The Department of Energy recommends that a skylight be
installed just above the surface of the roof—not below. Along
with the skylight there should be a curb with flashing. All
joints should be tightly sealed. A weatherization service
provider should make sure to optimize the spacing of skylights
if multiple skylights are to be installed.
Skylights can provide ventilation if the weatherization service
provider and occupants agree to install an operable skylight.
These skylights are designed with a hand-crank that opens the
skylight to let air in. These skylights typically have a screen
that keeps out bugs, leaves, and other outdoor elements. Since
hot air rises, installing an operable skylight may be a good way
to allow hot air to escape and passively cool a room.
Some skylights can be operable to allow additional ventilation
in a home.
Awnings and Window Shades
In a typical home, energy is lost through glass doors and
windows. On a hot day, more energy comes through one square
foot of glass than through an entire insulated wall. Solar
radiation through glass is responsible for approximately 20
percent of the load on an air conditioner.
Properly chosen and installed awnings can substantially
increase energy savings. Studies have shown that a fabric
awning can reduce heat gain by 55 to 77 percent depending on
the orientation of the window. This is because it blocks
sunlight from directly entering a space. However, awnings do
allow indirect light to enter a space, which is why they are
sometimes included in daylighting schemes. In the winter when
awnings are retracted, the direct sunlight can help light and
warm the space.
Window shades work in essentially the same way as awnings.

10. They let light into the space while preventing direct rays from
the sun and, thus, lower cooling costs. In most climates, they
are most effective when used on the south side of the building
where the sun’s rays are the strongest. In the coldest climates,
window shades may be detrimental to the heating of the
building using the sun’s heat.
Solar Light Tubes
Solar light tubes work by collecting outside sunlight,
transporting it, and distributing it into the home. Solar light
tubes are inexpensive and very effective. Solar tubes cost about
1/10th of the cost of a skylight.
Solar light tubes are round and are usually 12 to 14 inches in
diameter. These tubular skylights are easy to install in the
ceiling of a room that needs illumination, such as bathrooms
with no windows or dark interior corners. Light tubes add light
but little heat, which means that they do not increase the load
on the home’s air conditioner.
Some solar light tubes include a light so that they can provide
light during the nighttime hours, as well as during the day. This
allows the homeowner to enjoy a lighted space without having
light fixtures and solar light tubes in the ceiling.
Fiber Optics
Fiber optic daylight is a relatively new technology that captures
sunlight and pipes it to where it is needed. This technology
integrates sensors into light fixtures to make them more
efficient and to allow for a constant light level within the
home. A solar tracking mirror allows light to be captured and
concentrated before it is transported through fiber optic lines.
Important Rules
Here are some of the most important rules to consider when
including daylighting measures in the weatherization of a
home:Provide a daylighting scheme that works under the full
range of sky conditions at that location.
Consider materials, glazing, infrared (IR) filter, and UV filter in
window and skylight selection. Glazing is the coating applied
to windows to control transmissivity, particularly spectrally

11. sensitive transmissivity.
Minimize direct beam sunlight penetration into work areas.
Diffused light is much friendlier than direct sun. Filters and
blinds are effective light diffusers.
Window coverings can be used to make a room more
interesting, but a good weatherization service provider uses
appropriate materials and placement, as well.
Energy Efficiency of Appliances
In most homes, 90 percent of energy that is consumed by
appliances is consumed by the refrigerator, dish washer, and
clothes washer and dryer.
Fortunately, like most electronic devices today, huge strides
have been made in appliance energy efficiency over the last
decade. For example, several years ago a national refrigerator
manufacturer earned an award for producing a refrigerator that
used about the same amount of energy as a 75-watt light bulb.
Refrigerators
Refrigerators are the largest energy users of all household
appliances. They consume 9 to 15 percent of the home’s total
energy usage. Newer models generally consume up to half the
electricity used by older models. There have been numerous
recent improvements to refrigerators: the type and amount of
insulation and weather stripping, more effective controls, larger
and more efficient coils, and highly efficient motors. A
refrigerator with the freezer on the top is generally considered
to be the most efficient, followed closely by a model with the
freezer below.
Dishwashers
New dishwashers use less energy by using water that is 120ºF
instead of 130ºF for washing dishes. This saves energy that
would otherwise be used for the washer’s built-in water heater.
In addition, different cleaning cycles have been introduced that
save water and decrease standby losses in the house water
heater.
New dishwashers use less energy by offering different cleaning

12. cycles.
Clothes Washers and Dryers
When it comes to clothes washers, the front loading models are
far more energy efficient than the top loading models. They
also use less water. In addition, newer models have a higher
revolution per minute spin cycle so that the clothes dry more
quickly and come out of the washer drier. This means that less
energy is required for drying the clothes.
Clothes washers may be rated by one of two systems: the
Energy Factor and the Modified Energy Factor. The Energy
Factor (EF) describes the cubic feet of clothes washed per
kilowatt-hour of electricity. The Modified Energy Factor
(MEF) is the same as the EF but also takes drying into account.
One of the major improvements to clothes dryers has been the
introduction of temperature and humidity sensing devices that
work to prevent over-drying and save 5 to 15 percent of energy
consumption compared to older models.
Lastly, electric clothes dryers typically cost $0.15 to $0.20
more to dry per load than gas dryers.
Ovens
A weatherization service provider should be able to tell if an
oven or stovetop is older or newer. Older gas ovens and
stovetops can be identified by the presence of a pilot light.
Newer models have electronic ignition.
The weatherization service provider should take the
homeowner’s cooking habits into account before replacing
cooking appliances. If the homeowner does not cook regularly,
upgrading to a newer, more efficient oven and/or stovetop will
not significantly affect energy use or savings. Because ovens
and stovetops do not use a large amount of energy, a
weatherization service provider most often will not replace the
home’s current oven and stovetop.
However, if the oven and stovetop are about to come to the end
of their useful life, they may be replaced. In such cases, the
weatherization service provider should keep in mind that
convection ovens are generally more efficient than conventional

13. ovens.
Appliance Information and Energy Ratings
The model number, serial number, age, and other information
about most appliances can be found on the manufacturer’s
label. These labels are in differing areas on the units and their
location can often be found on the PartSelect website or
AppliancePartsPros.com. One can also visit the Kouba-Cavallo
Associations, Inc. website for more information.
Information about energy ratings for most appliances can be
found on a number of websites.Environmental Protection

Energy consumption is a major portion of any structure’s life
cycle. We have already discussed the factors related to a
structure’s heating and cooling systems and the importance in
maintaining maintenance procedures to ensure that each system
is functioning correctly throughout the seasonal changes. Let’s
move on and take a look at the lighting and other appliance
loads within our structure. It is important within our
weatherization thought process that we address the issues and
concerns that surround lighting and appliance fixtures that are
not energy efficient. Energy Star appliances and compact
fluorescent lights (CFLs) or Light Emitting Diode (LEDs)
lighting units should be installed to ensure that our structure has
become more energy efficient through our new weatherization
upgrades. The following YouTube video presentations will
provide you with valuable information on selecting and
replacing outdated lighting lamps and appliances with more
