Home Energy Audits
Technology Snapshot & Benefits:
A home energy audit is an important tool for energy
conservation and savings by homeowners. Considering the high cost of energy
today, lowering utility bills by making a home more energy efficient is
essential. An energy audit can help identify areas of a home that can be a
financial and energy drain, in order to save on heating, electricity, water, or
gas bills. By reducing costs, consumption, and the reliance on foreign,
non-renewable, energy sources a home energy audit is one of the most cost
effective ways to not only make your home more energy efficient, but in addition
more comfortable as well. Auditors come into your home, complete an individually
unique analysis for your household, and give suggestions on areas that need
improvements. Some of the improvements that are often suggested involve sealing
doors and windows, adding
insulation, weather stripping, improvements in ventilation, ducting and
airflow, and improvement of heating and cooling systems to function more
Multiple audit options exist on the market, with
everything from do-it-yourself packets to professionals that specialize in this
industry. Whether you elect to hire a professional or conduct a home energy
audit on your own, the process aims to diagnose the problem areas in your
household in terms of energy efficiency and comfort.
Various tools and testing methods exist to help in
the diagnostic process of a home energy audit. Blower door tests and infrared
technologies are two of the most valuable tools that an energy auditor has,
second only to their knowledge and experience. Both types of analysis serve to
aid the auditor in different ways. A blower door test determines the air
tightness of a home and helps to identify potentially problematic areas where
air leaks are an issue. Infrared technology has recently entered the energy
audit industry and enables an auditor to see hot and cold spots behind walls and
other structural components.
The advantage to hiring a professional to conduct a
thorough home energy audit is that they are more likely to see things that a
homeowner may miss. However, by following directions on sites such as the
Department of Energy to conduct self performed home energy audits,
homeowners can identify some of the larger and more important issues within your
home without professional assistance.
Keep in mind that energy audits can be conducted on
commercial properties as well, however you'd want to hire a commercial
specialist for those jobs.
Estimated Cost Savings:
The estimated cost savings associated with home
energy audits are three fold. In most cases if the homeowners follow the
suggestions of the auditor they will find an improvement in comfort, an increase
in the level of efficiency, and a decrease in monthly utility bills. Most
solutions which arise from an energy audit eventually pay for themselves through
the savings on bills.
Completing a home energy audit is the optimal method
for finding areas in a home that waste energy. Using the findings of an energy
audit to properly seal and insulate a home is important for energy conservation.
By diagnosing the problem areas and making the right improvements many
households could easily see a reduction in home energy use by 30 to 40 percent -
and in some cases even cut in half. The typical household in the United States
consumes so much energy in electricity and heating fuel that its greenhouse gas
emissions are equivalent to two average automobiles. Cutting your energy
consumption by 25 percent may be equivalent - in climate impact - to eliminating
emissions from a car for 6 months each year, or keeping three to four tons of
CO2 out of the atmosphere.
An import point to keep in mind is that repairs resulting from an energy
audit also increase a home's value and return on investment.
Issues in energy audits may arise when an auditor is inexperienced or a
homeowner conducts a poor self initiated home energy audit. Negative results
rarely stem from performing an energy audit as it is just a diagnostic step in
the energy efficiency process. Issues may arise once work has begun on the
improvements decided upon by the homeowner, but this should be rare if your
audit was thorough and precise.
Some confusion may arise when trying to decipher the
differences between audit, rating, and assessment. One of the major differences
between home energy rating and an energy audit is that the rating is a
recognized tool in the mortgage process. The information derived from the home
energy rating provides important information about a home's energy performance
and the economic analysis necessary to support lending decisions. The home
energy audit is very similar to home energy assessments which focus to diagnose
a home's problem areas and address those issues rather than certify that a
property meets specific environmental and energy consumption standards.
The regional issues regarding this technology/practice revolve around the fact
that this is a very climate specific field. Often the best solution to an energy
efficiency problem is unique to the region in which it comes. Find a
professional energy auditor who is local or comes from a similar climate area.
Installation (Getting It Done):
There are numerous resources available to contact energy auditors in your area.
In most cases utility companies may have some contacts in the industry that they
can refer and often supplement some of the costs of the consumer. Contact your
local utility provider today for more information on certified auditors. Make
sure the company you go with has a good reputation, can offer referrals,
conducts blower door tests, and that either does or subcontracts infrared
scanning technologies. Organizations such as
Energy Star also have lists of certified home auditors available to
consumers. In addition be sure to check that the company is local and well

Home Energy Audit (9:26) - Green Dream Group - An important step to ensuring
that your home is operating at its highest possible level is to get a home
energy audit. These audits will not only tell you if your home is wasting
energy, it will tell you where and, in some cases, how to fix it. One of the
most common tools used in home energy audits is the blower door test, seen in
this video explaining a typical audit.
