Home Energy Audit (what is in a name) Our
"Home Energy
Audit" is completed as two services – the
“Opportunity Survey,” which is step one of our
Energy Independence Process, and then “Modeling and Analysis” which is steps two and three
of our Energy Independence Process. These
services are described here:
A: Opportunity Survey
is conducted by a certified home energy
advisor working with the home owner. This
survey typically takes about five hours. The following areas are addressed
during the survey:
- Outside inspection and measurement of the home is
performed.
-
Solar access is generally assessed.
-
Combustion appliances
furnace, water heater, gas stove, etc. are checked for
carbon monoxide, draft and
spillage under worst case conditions.
- Your heating and cooling systems efficiencies are noted
or evaluated, depending on type and age.
-
The
distribution system
air ducts, water or steam system is assessed for thermal isolation and leakage.
- Insulation levels and installation are evaluated in your
home’s attic, walls and basement or crawl space.
- Windows and doors are surveyed for thermal and air
leakage performance.
- Your home’s pressure boundary is evaluated for air leakage
performance with a blower door.
- Major appliances (washer, refrigerator, etc.) and
primary lights are surveyed for energy efficiency.
During this home visit, a great deal of
data will be collected for later energy
analysis and to estimate costs and savings. We will get your expectations on future energy prices
and how aggressive you want be in reducing your energy
dependence and carbon footprint. All this information is
important in providing you with the very best, personalized
recommendations.
Another
key aspect of this service is the time taken
for educational topics. The home energy
advisor will cover many key concepts and
facts that relate to the efficient and safe
operation of your home, the available
products and services. He will also answer
every question you have related to your home
and saving energy. If research needs to be
done to answer a question, a follow-up
answer will be provided. We also explain
financing and other incentive options.
At the end of the visit, you will be
given a summary assessment and our
recommendations. This report highlights key
energy saving opportunities and any health
and safety issues. It provides you with the
information to decide whether or not to go
to the next step, whether to do the work
yourself, or perhaps just to think about it
for a while.
B: Modeling and Analysis
is conducted as two separate components.
First the data entry and energy model building is performed
at our office. Then, when your
final report is ready, we will schedule a
meeting with you at your home to discuss the
results and recommendations. With this
information, you will be have the cost and
energy savings information to prioritize
changes and select those you want to
implement. These two steps are expanded upon
next:
- Based on your direction, Home Energy Advisors will input
the data collected during the Opportunity Survey into our
computer programs to estimate energy efficiencies for
current and potential
home components and other measures. We
will obtain cost estimates for potential energy saving options
for your specific home and enter them into the system. We
will then analyze the results and develop option packages
that we believe you should consider, along with potentially
other measures to make your home more energy-efficient,
safe, comfortable and durable, as part of the final report.
These recommendations will be based on your expectations,
goals and objectives and fit within your budget and planned
financing.
- During the review and discussion session, we will
explain the various recommendations and why we made them. We
will help you evaluate the various options by showing you
how each recommendation contributes to you becoming more
energy independent. We will also discuss the pros and cons
of various approaches and materials. The home meeting
typically takes an hour or more, depending on your questions
and desire for detail.
C:
Implementing Your Plan If you decide to invest in your home and energy independence, we will facilitate financing, if you desire. We will recommend excellent contractors that do quality work at a fair price or you can work with any BPI accredited contractors. We monitor the work and perform final checks to be sure
your home is safe and your objectives are met. Any services Home
Energy Advisors may provide in this phase will be part of the
implementation recommendations and priced within those
proposals.

Solar Access is Generally AssessedHome Energy Advisors take digital pictures of your house from
solar south
approximately 14
degrees west of magnetic south in the
Capital Region and the view toward solar south. We determine
exposure percent to sun and solar radiation from the ground at the
best spot within 10’ of your house. Later if a more detailed survey
is required, Home Energy Advisors or the solar contractor can
perform these measurements from the exact spot you are considering
installing solar panels (heat collectors or photovoltaic). The cost
of this future service will depend on the number of locations being
evaluated and the specific locations (ground, roof, 15’ above
ground, etc.).

Carbon Monoxide, Draft and SpillageCarbon monoxide is a by-product of combustion that may be present
in dangerous levels.
carbon monoxide is responsible for over 500 deaths in the US annually Spillage is the combustion
gases that escape around the combustion device during start-up.
Draft is the pressure exerted in the flue to draw combustion gases
out of the house. Many times the measure of how well your house is
dealing with these dangers changes over time – any insulation or
weatherization that may have been done can affect them, new
combustion appliances can affect the overall performance, additional
house fans and exhausts can also have an effect, etc. It is
important to evaluate this aspect of your home’s safety every time
these types of changes are made to be sure every thing is operating
safely, as they should be.

Home Components and Other MeasuresHome component considerations include attic insulation, wall
insulation, window replacements or insulation, air sealing
improvements, etc. Other measures include lighting changes,
appliance and/or furnace upgrades, active or passive solar
improvements, etc.

Home Energy AuditThere are
numerous names for the Home Energy Audit,
including the name Comprehensive Home
Assessment (CHA) used by Home Performance
with Energy STAR® program. We use the name
Home Energy Audit for two reasons: 1) it is generic, shorter and familiar to more people, and 2) our service includes more focus on using the
sun, more educational content, generally
takes more time to perform, and is delivered
in two steps, the second of which is
optional. So to avoid confusion, we call it
a Home Energy Audit and define it
here.
