™ – Home Energy Inspection™ is a standardized non-diagnostic
inspection of a home performed according to the International Standards of Practice for Performing a
Home Energy Inspection™, which are publicly available at https://www.nachi.org/sop-home-energy-inspection.htm
. The inspector may use a reporting software to produce reports or documentation of observations, but specific software is not required. InterNACHI's web-based energy calculator to produce a Home Energy Report™ of energy savings estimates and recommendations for energy upgrades is available for inspectors in the U.S. only at https://www.nachi.org/home-energy-inspection.htm
Energy Inspection ADVISOR – A member of InterNACHI, the International Association of
Certified Home Inspectors, trained and
certified according to these Standards. ADVISORS are required to provide
review, monitoring, supervision, and guidance (Quality Control) to Home Energy INSPECTORS in accordance with these
Standards as part of the Quality Assurance (QA) of the Home Energy Inspection Program. (Capitalization within these Standards are for emphasis only.)

Home Energy Report™ -
The InterNACHI Home Energy Report™ is a web-based software that may be used a Home Energy Inspector after performing a Home Energy Inspection™ www.nachi.org/home-energy-report.htm
. It provides the client information about: (a) how much the inspected home will cost to operate; (b) where energy (and, therefore, money) is being wasted in the home; and (c) what can be done to save energy and increase comfort by investing in home energy upgrades. This software functions on U.S. housing stock only.
Home Energy Score
- The United States Department of Energy (DOE) Home Energy Score
is a number between 1 to 10, with a score of 10 indicating the home has excellent energy performance. A score of 1 indicates
the home needs extensive energy improvements. The Home Energy Score is essentially a label providing: (a) a numerical representation of the energy performance of a home, (b) recommended energy improvements, and (c) associated cost savings
estimates. The Home Energy Score is not a standardized inspection process, such as a Home Energy Inspection™ described in these Standards.
Inspection - A home inspection is a non-invasive, visual examination of a
residential dwelling, performed for a fee, which is designed to identify observed
material defects within specific components of said dwelling. Components may
include any combination of mechanical, structural, electrical, plumbing, or
other essential systems or portions of the home, as identified and agreed to by
the Client and Inspector, prior to the inspection process.
- A visual examination at readily accessible systems and components using
normal operating controls and accessing readily accessible panels and area.
Inspector - One who performs an inspection.

104.0 HOME ENERGY INSPECTION™
104.1 General Provisions
The purpose of the Home Energy Inspection™ is to:
- Determine the general condition
of the home with respect to energy performance;
- Educate the homeowner/occupant and help them understand the energy performance of their homes and how they compare to other homes nationwide; and
- Promote energy efficiency to homeowners and encourage investments in energy upgrades.
Home Energy Report
™. The Home Energy INSPECTOR
shall produce a written report or documentation of their observations made on the day of the inspection. A reporting software may be used. InterNACHI's Home Energy Report™
, a web-based energy calculating software for U.S. housing stock only, shows a general range of a home’s energy efficiency
based on certain house assets (insulation, equipment age, general condition,
energy usage and costs) and a lookup matrix based on regional norms and
climate, based upon the web-based inspection tool from Lawrence Berkeley
National Laboratory and supported by the DOE, Office of Energy Efficiency and
Renewable Energy, found at http://hespro.lbl.gov/pro/
Note: The Home Energy Report™ is not the U.S. Department of Energy's Home Energy Score, which is number (a miles-per-gallon rating) of a scale from 1 to 10. See Section 102.0 of these Standards. The Home Energy Report™ may include a Home Energy Score, depending upon whether the inspector is qualified to produce one.
Data Points. In order to perform the inspection, the
INSPECTOR conducts a visual, non-diagnostic inspection of the home and collects about 45 data
points. To estimate the home's energy use, convert that into a savings estimate
and develop recommendations for energy improvements, the inspector may use a reporting software, but this is not required. A
web-based reporting tool created by InterNACHI and a home energy calculator developed by Lawrence Berkeley National Laboratory
in collaboration with the U.S. Department of Energy called the Home Energy Report™ may be used.
The Home Energy Report™ lists recommendations for energy upgrades that are specific to the
house as well as an estimate of how much these improvements can reduce the
utility bill. The Report™ is based upon the data collected by the INSPECTOR and
on national installation cost averages for specific energy improvements and
state average utility costs. These recommendations are created by the U.S. Department of Energy's Lawrence Berkeley National Laboratory.
Home Energy Inspection™ is performed in accordance with the International Standards of Practice for Performing a Home Energy Inspection
and shall include on-site visual inspection of the
energy features of the home, and documentation of its general
condition, including envelope features and ages; equipment types,
characteristics and ages; and, appliance and lighting characteristics. Where
appropriate and available, the inspector may include a review of utility use
and billing history. The Home Energy Inspection™ is a visual-only, non-diagnostic inspection and
does not require the use of a blower door, duct leakage test, an infrared
camera, or other diagnostic test equipment.
Inspector may interview the homeowner regarding energy and comfort problems.
The Inspector will explain the limitations of the inspection and provide an
overview of the benefits and value of a more comprehensive home energy audit as
defined by the U.S. Department of Energy (DOE). Refer to DOE article at http://energy.gov/energysaver/articles/professional-home-energy-audits
. The interview shall include, but is not limited to, the
following subject areas:
104.4.1 Comfort concerns, including areas of the
home that are too hot or too cold.
104.4.2 Energy billing concerns.
104.4.3 Indoor air quality concerns.
104.4.4 The potential for the homeowner to move to a
more comprehensive, diagnostic home energy assessment.
104.4.5 Interest in potential home energy
104.4.6 Low- and no-cost energy upgrades that can be implemented by the homeowner.
Utility bills. The Inspector may request copies of utility bills or written permission to
obtain the energy use information from the utility company, and may use them to inspect the home.
Referral to a Home Energy Professional. The Inspector shall advise the homeowner on where to locate qualified
individuals to conduct a more comprehensive home energy assessment and/or qualified
contractors to complete the energy upgrade work on the home.
