The following are protocols and guidelines for using the Home Energy Scoring Tool and entering the
information based on what is observed on site. These guidelines are in addition and supplementary to
the Tool Tips displayed on the Scoring Tool. Be sure to open the Tool Tips on the Scoring Tool by
clicking on the question mark icons
- they contain important guidance and information as well.
Correctly interpreting your onsite observations and converting those interpretations into the
appropriate data inputs is a critical part of accurately scoring a home. Complex homes will require
greater interpretation, for which adherence to these guidelines will be most important – please
reference this document whenever you’re unsure as to how you should characterize certain home
components in the Scoring Tool. Remember, use your best judgement! These guidelines cannot
possibly characterize every situation, and in many cases you’ll need to select the choice that most
closely matches the situation you are assessing. Some of the details in these guidelines only apply to
those Assessors who are using the Home Energy Score web interface. If you are using a third party
software or app to enter the data, please contact your program Partner and/or the software
provider for more details about the system you are using.

Scoring Tool Protocols
•
Do not share your Assessor login or allow others to score homes through your
login, and do not attempt to log in and score homes on an Assessor account/ID
other than your own; doing so will compromise your status as an Assessor and
your access to the Scoring Tool may be blocked indefinitely.
• The Home Energy Score is only appropriate for scoring single family homes and
townhouses/row houses/duplexes. Do not attempt to score mobile homes
(manufactured housing), floating homes, or apartment/multifamily dwellings. If
the floor of a dwelling is the ceiling of a separately owned/occupied dwelling
below it (or vice versa), it is considered an apartment and should not be scored.
• Enter the home’s address appropriately – use the correct postal standardized
version of the address, or the Google maps validation feature when possible
(select the “Corrected” address, if appropriate). Use correct punctuation (avoid
using all caps!), keeping in mind the address you enter will appear on the Score
report – ensure that it looks professional and does not contain typos. (If you are
scoring two or more buildings that share the exact same address [i.e., a guest
cottage or in-law house], use the proper address for the primary building and
append an “A” to the street number of the secondary building [e.g. 1500 Main St.
and 1500A Main St.]). Incorrectly entered addresses cannot be changed or
corrected. If you realize you have entered the address incorrectly once you’ve
started the assessment, abort and delete the session, and start over by entering
the correct address. If you’ve already created the Score with an incorrect
address, you must inform your Partner program administrator so that steps can
be taken to delete (void) the Score and prevent possible repercussions at time
of sale. You will need to create the Score again with the correct address.
• It is critical that you select the proper Assessment Type when you begin the data
entry:
Assessment Type:
Description:
Initial (official) First (original) official assessment – one time only per house
Final (official) Final official test-out assessment, following improvements done since the “Initial” score
QA Quality Assurance evaluation assessment by QA Assessor. If the assessor needs to
correct the QA assessment inputs, use this type for all runs. DO NOT use Corrected.
Alternative EEM Alternative Energy Efficiency Measures assessment for creating a customized “projected
score” label – see “HEScore Data Entry Guidelines”
Test Experimental, practice, or trial (test) sessions – can be used for the same house as often
as necessary
Corrected (official) Corrections or changes to previously run Initial or Final scores

▪ Always select “Initial” for the first official assessment, even in cases where
the home has recently been updated or improved and will likely not be
scored again. Absolutely no home should have more than one “Initial”
session.
▪ Select “Final” for the official test-out assessment following improvements
made after an “Initial” score – do not select “Final” unless the house has
already had an “Initial” score.
▪ “Corrected” must be selected for sessions incorporating corrections to
“Initial” or “Final” scores only - do not select “Corrected” for corrections to
unofficial scores, or when the home’s address has been incorrectly entered.
▪ “Mentor” should only be selected for mentoring sessions – see the
“HEScore Mentoring and QA Guidelines” document or follow the guidance
of your mentor.
▪ “Preconstruction” should only and always be selected for assessments
being done from building plans or blueprints prior to a home’s
construction, even if a previous preconstruction assessment is being
corrected.
• Utilize the Home Energy Score Assessor Calculator to determine weighted
averages, find values for multiple systems, and calculate accurate equipment
efficiencies or defaults. Individual calculators from the Assessor Calculator are
embedded in the web browser version of the Scoring Tool, and can be easily
accessed by clicking on the calculator icon . The calculator is provided to each
new Assessor as an attachment to the confirmation email, can be easily
downloaded from the Portal, or sent to you if you notify us at
[email protected].
• Use the Tool Tips in the Home Energy Scoring Tool. The Tool Tips are accessed by
clicking on the question mark icons
available throughout the Tool, and provide
important and helpful information regarding each entry or selection. If more
detail or clarity is needed, refer to the guidance in this document.
• Measure the conditioned floor area (CFA) manually. Do not use real estate listings
(MLS), appraisals, county records or websites such as Zillow to determine CFA
square footage, as these sources are often inaccurate and/or out of date.

• Proofread your data entries thoroughly using the Summary View before finalizing
the inputs and generating the Score report. Once finalized, the data cannot be
changed. If there was an error to an official score (“Initial” or “Final”), you must
select “Corrected” as the score type when you correct or re-enter the data to
generate a new Score report.
• Avoid opening the Home Energy Scoring Tool in multiple tabs or logging on to the
Tool in more than one instance at a time. Doing so may cause an error and the
Tool may lock your session.
• You must create at least one official Score within a six month period in order to
remain an active Assessor; otherwise your account will be de-activated without
prior notification.
Data Entry Guidelines
Some of the details in these guidelines only apply to those Assessors who are using the Home Energy
Score web interface. If you are using a third party software or app (on a mobile device) to enter the
data, please contact your Partner program administrator and/or the software provider for more details
and guidance about the system you are using.
Address
Please see the third bullet under protocols (above). It is of utmost importance that the address be
entered correctly, so that it aligns with other official records. Once the address is registered and the
data entry begins, the address cannot be changed. If the address is entered incorrectly the data entry
should be aborted and the session should be deleted. If the Score has already been created, notify your
Partner, or [email protected], of the error. In either case the home must be scored again using the
correct address and the original assessment type – do not use “Corrected” as the assessment type
when the session is being created to fix an assessment previously created with an incorrect address.
Section 1: About This Home
Assessment Date - Enter the date when the assessment inspection was done so that the score reflects
the conditions at the time of the inspection.
Year built – Enter the date the majority of the house was built. If the house was an 800 ft² bungalow
built in 1950, but a 1500 ft² addition was added in 1975, enter the year built as 1975.
Number of bedrooms – A bedroom is defined as a room purposely built as such and defined as such by
local ordinance. If there are more than 10 bedrooms, select 10.

Stories Above Ground Level – If a house has a level that is 50% or more below grade that level should
be characterized as a basement. For example, if more than half of the lower (walk-out) level of a two
level ranch style house is below grade, the house should be characterized as 1 story, with a basement
for the foundation. For houses considered to have a half story above, round up to the next whole
number. For example, Cape Cod’s are sometimes characterized as 1½ stories; in the Scoring Tool they
should be entered as 2 stories, unless the upper ½ story is actually an unconditioned attic. Split level or
tri-level homes should often be entered as having two foundations, as follows:
a.) If there are two full levels on either side of the split, the house is 2 stories and the two
foundation types will be basement and either crawlspace or slab-on-grade.
b.) If there are two full levels on one side of the split, one full level (usually over crawlspace) on the
other side, and the lowest full level is more than 50% above grade, the house is 2 stories and
the two foundation types are slab-on-grade and crawlspace – if there is no crawlspace then
only one foundation type (slab-on-grade) is necessary.
c.) If there are two full levels on one side of the split and one full level (usually over crawlspace) on
the other side, and the lowest level is more than 50% below grade, the house is 1 story and the
two foundation types are basement and either crawlspace or slab-on-grade.
Interior Floor to Ceiling Height – If there are different ceiling heights, average the heights using a
weighted average calculation based on areas, and round to the nearest whole number – the embedded
calculator or the “Averaging Calculators” tab in the Assessor Calculator can be used for this. Round to
the nearest whole number, and if the calculated average height is exactly between two whole
numbers, round up. For example, if the average ceiling height is calculated as 8.4 ft., round to the
nearest whole number (8 ft.); however, if the average ceiling height is calculated as 8.5 ft., round up to
9 ft.
Conditioned Floor Area (all stories combined) square feet – This must be based on actual
measurements physically done by the Assessor. Measuring the outside dimensions of the house is
often a preferred method for calculating floor areas, as long as it can be done accurately (subtracting
for wall depth). Do not use real estate listings (MLS), appraisals, county records or websites such as
Zillow to determine square footage, as these are often inaccurate and/or out of date. Conditioned floor
area must include all conditioned spaces that are intentionally heated and/or cooled including
conditioned basements, but must not include conditioned crawl spaces. An area is considered
conditioned only if there are duct registers, radiators, or some permanent source of heating and/or
cooling present which provides conditioning - closets, cupboards, stairwells, and hallways within the
conditioned envelope are considered part of the conditioned area. Many auditors have been trained
that a basement should be considered conditioned if the ducts and/or HVAC system are in the space,
but for the Home Energy Score there must be direct delivery to the basement area for it to be

considered conditioned (i.e., “unintentionally conditioned” does not count). Do not include commas in
the value entered for the conditioned floor area entry.
Direction faced by front of house – Enter the compass direction the house is facing. This can be readily
determined with an analog compass, or by looking up the home’s address on map software (such as
Google Maps) and ascertaining the compass direction. Be wary of using phone compass apps, as they
are often unreliable. Please note this exception to the above guidance: If the dwelling is an end
townhouse unit and the front door is on the long side, characterize the front of the townhouse as the
short side opposite the back of the unit. For instance, if the long side with the front door of the end
unit is facing west and the short side with the back door is facing south, enter “north” as the direction
that the front of the townhouse is facing, even if there is no door on that side. (The Scoring Tool
assumes a 5:3 front to side wall ratio for standard homes and a 3:5 front to side wall ratio for
townhouses, i.e. the Tool always assumes that the front door of a townhouse is on the short side.)
Air leakage rate – If a blower door test has been conducted on the house and the results are available,
enter them as @CFM50. Do not include commas in the entry. If the house has also been professionally
air sealed, select this option. If a blower door test result is not entered, the Assessor will need to
characterize whether the house has been previously air sealed. “Air sealed” means professionally
treated to seal or control major air leakage pathways. Do not confuse air sealed with weatherization,
and do not assume a home is air sealed if the homeowner says it is – you must observe actual physical
evidence (i.e. foam sealed top plates in the attic, etc.). If there is no physical evidence that the house
has been professionally air sealed you must assume it is not. New construction should only be
considered to have been professionally air sealed if it meets the requirements of a new home
efficiency label, e.g. Energy Star, LEED, etc., or there is documented evidence.
Section 2: Roof, Attic & Foundation
Roof / Attic - If there is more than one type of roof construction or finish, or more than one type of
ceiling, attic, or insulation type, you should enter the information as two roof/attic types by clicking
“Enter a second roof / attic”. If there are more than two types, combine the most similar of the types
to narrow the number of entries to two, and calculate weighted average R-values for the combined
areas appropriately.
Attic area – Attic area is the ft² surface area of all attic areas, including cathedral or vaulted ceiling
surface areas and knee wall surface areas. The area of skylights, if present, should be included as well.
If there is just one flat roof/attic type, the attic area will be the same size as the upper story
conditioned floor area you measured while determining the home’s conditioned floor area. If there is
more than one roof/attic type, click “Enter a second roof/attic”. Additional fields will be displayed so
that the characteristics of a second roof/attic type can be entered – be sure to enter the correct area

for each attic. If there are more than two roof/attic types, combine those that are most similar to
narrow down the variables to just two and use the “Averaging Calculator” (embedded in the Scoring
Tool, or from the Assessor Calculator) to perform a UA calculation in order to determine the overall
insulation R-value of the types that were combined; for example, knee wall attic areas can be
combined with flat attic areas. The areas for sloped attics (vaulted ceilings and cathedral ceilings) can
be calculated with the “Cathedral Ceiling Area” Calculator (embedded in the Scoring Tool or from the
Assessor Calculator).
Unless the house is a single story on a slab, crawlspace, or unconditioned basement, the attic area will
not be the same as the conditioned floor area. For example, if a single story house has a conditioned
basement (directly beneath), the attic ft² will be half of the total conditioned area. Do not include
eaves or attic spaces directly over unconditioned areas (such as porches or garages). You can use the
“Floor-Roof Area” checker in the Assessor Calculator to verify that your attic area calculation is logical.
The total (combined) roof/attic area must be at least as large as the total (combined) foundation area,
otherwise the Scoring Tool will indicate a validation error.
Construction and Exterior Finish - Choose the predominant characteristics. If the home’s actual roof
construction or exterior finish is not one of the choices in the Tool, select the most similar choice. If the
home has a bitumen membrane or some type of rubber or plastic membrane roof finish, choose “Tar
and Gravel” as the roof’s Exterior Finish.
(Roof) Insulation level – This is in reference to the roof assembly only, not the attic floor. Select the
nearest R-value from the dropdown menu choices – if there is no insulation in the roof, select R-0. Roof
insulation R-value in a cathedral type ceiling should be de-rated based on the current installation
quality using the Assessor Calculator. If the roof insulation cannot be readily determined, try to
estimate the installation depth and quality based on local building practices and codes. If the attic is
vented, any insulation installed in the roof assembly is irrelevant - select R-0, even though there is
insulation attached to the roof assembly. If there are multiple insulation levels, perform a UA
calculation (w/ the Assessor Calculator) and round to the nearest R-value on the dropdown menu. If a
calculated R-value falls halfway between two menu choices, choose the lower (least energy efficient)
value.
Roof Color – Choose the color of the roof from the following choices:
White
Smooth building material surfaces covered with a fresh or clean, stark white paint or
coating.
Light
Masonry, textured, rough wood, or gravel surfaces covered with a white paint or
coating.

Cool Color
If the homeowner knows the reflectivity of the roof, choose cool color and enter the

Attic or Ceiling Type – Choose the type from the dropdown menu. If Cathedral Ceiling is chosen the
insulation value must be entered under “Roof: Insulation Level”, as the Attic floor insulation data entry
field will become hidden.
Attic Floor Insulation – This entry is for flat attic insulation, vaulted (sloped) attic insulation, and knee
wall insulation. Select the nearest R-value from the dropdown menu choices. Attic insulation R-value
should be de-rated based on the current installation quality using the Assessor Calculator. If there are
multiple insulation levels, perform a UA calculation with the “R-Value – Weighted Average” calculator
in the Assessor Calculator and round to the nearest R-value on the dropdown menu. If a calculated Rvalue falls halfway between two menu choices, choose the lower value. If you combine an attic knee
wall surface area with a flat attic area, you’ll likely need to perform a UA calculation to determine the
overall R-value since knee wall insulation is often significantly different from flat attic insulation. Be
sure to de-rate the insulation based on the quality of the current install, and to account for any voids
(uninsulated areas, such as the attic hatch) by performing a weighted average R-value calculation on
the Assessor Calculator. A void of just 2% (uninsulated space) can have a significant impact on the
overall R-value.
Foundation - If there is more than one type of foundation construction or foundation insulation type
you should enter the information as two foundation types by clicking “Enter a second foundation /
floor”. If there are more than two types, combine the most similar of the types to narrow the number
of entries to two, and calculate weighted average R-values for the combined areas appropriately.
Foundation area – Enter the ft² area for each foundation type. If there is just one foundation type, the
foundation area will be the same size as the lower story conditioned floor area you measured while
determining the house conditioned area, excluding cantilevered areas or bump outs, etc. If there is
more than one foundation type, including cantilevers and bump outs, click “Enter a second foundation
/ floor”. Additional fields will be displayed so that the characteristics of a second foundation type can
be entered – be sure to enter the correct area for each. If there are more than two foundation types,

combine the most similar types to narrow down the variables to just two and use the Assessor
Calculator to perform a UA calculation if necessary in order to determine the overall insulation R-value
of the combined types. The total (combined) foundation area must not be greater than the total
(combined) roof/attic area, otherwise the Scoring Tool will indicate a validation error.
Foundation Type – Choose the type from the dropdown menu. If Slab-on-grade is chosen, an insulation
value must be entered under “Foundation walls insulation level” - see below. An unconditioned garage
under a conditioned living space should be characterized as an “Unvented crawlspace”. For a house
built on an open foundation such as on piers, the foundation type should be characterized as “Vented
crawlspace”. Also, if the house has significant bump-outs or cantilevered areas, or living space built
over a carport or outdoor area, a second foundation type should be entered for those spaces and
“Vented crawlspace” should be chosen as that foundation type. Cellars under houses with rubble
foundations should be classified as “Vented crawlspace” if “Unconditioned basement” does not seem
appropriate – use your best judgement.
Floor Insulation above basement or crawlspace – If the foundation type is basement or crawlspace, the
insulation value between that space and the floor above should be entered. Select the nearest R-value
from the dropdown menu. If there is no insulation, select R-0. If there are multiple insulation levels
within one foundation type, perform a UA calculation and round to the nearest menu choice. If a
calculated R-value falls halfway between two menu choices, choose the lower value. Be sure to
account for insulation voids, which can reduce the overall R-value significantly. Loose hanging
insulation (not in direct contact with the surface above) is irrelevant, and should be assigned an Rvalue of 0.
Foundation Wall Insulation level – If the foundation wall is insulated, select the nearest R-value from
the menu choices. If there is no insulation, select R-0. If there are multiple insulation levels, perform a
UA calculation and round to the nearest dropdown menu choice. If a calculated R-value falls halfway
between two menu choices, choose the lower value. If the foundation type is slab-on-grade and you
have specific evidence that insulation is installed under or around the perimeter of the slab, select R-5;
otherwise select R-0.
PLEASE NOTE - Both the foundation and floor insulation fields must have a value entered. If one of
them does not apply to the house, select R-0 for the field that does not apply. Unlike the roof and attic,
it is okay to enter non-zero values in both of these insulation fields. For example, a conditioned
crawlspace might have insulation on both the foundation wall and between the floor joists of the
crawlspace ceiling – both values should be entered. If there is no insulation at all, select R-0 for both.

Section 3: Walls
If the wall construction or characteristics on one or more sides of the home is different from the
others, select No for “…same on all sides?” and then enter the data for each individual side of the
home. If all sides of the home are constructed the same and have the same characteristics, the data
only needs to be entered once. For townhouses, enter the information about the exterior (exposed)
walls only.
Townhouse – This includes row houses, duplexes, townhomes, or any house sharing a single wall with
another house. Select the position relative to the other units: middle, right (end) or left (end). The right
and left positions are determined by street view, facing the front of the house from the street (see
exception for “Direction faced by front of house”, above). When “Townhouse” is selected the Scoring
Tool automatically changes the front/back to side wall ratio from 5:3 to 3:5.
Construction and Exterior Finish – If there is more than one type on a single wall choose the
predominant type. If the home’s wall construction or exterior finish is not one of the choices, select
“Wood Frame” and “Wood Siding”. If the home has insulated vinyl siding and the insulation on the
siding is at least 1/3 inch thick (or greater), characterize the construction as “Wood Frame with rigid
foam sheathing”, but do not add the siding or sheathing R-value to the wall insulation R-value. If the
siding or the sheathing has insulation that is less than 1/3 inch thick, disregard it.
Insulation – Select the nearest R-value for wall cavity insulation from the dropdown choices. Do not
calculate and enter a total wall assembly R-value – the Scoring Tool already accounts for the wall
assembly components, so only the cavity insulation R-value is required for the “Insulation Level” entry.
Use the default values provided in the “Wall Insulation Defaults” tab of the Assessor Calculator, based
on the region and age of the home – do not de-rate these values. If you have better information or
different size wall cavities than those listed in the Calculator, de-rate the R-value by type and depth
using the “Insulation De-rate Calculator” in the Assessor Calculator, using a “fair” installation quality
(unless you have evidence to characterize it otherwise). If there are multiple insulation levels on the
same side, perform a UA calculation with the Assessor Calculator and round to the nearest R-value on
the dropdown menu. If a calculated R-value falls halfway between two menu choices, choose the lower
value.
Section 4: Windows & Skylights
Skylights - If there are multiple skylight types, enter the skylight characteristics of those that make up
the largest combined area. Solar tubes/sun tunnels can also be characterized as skylights.

Skylight Area – Enter the total skylight area of all skylights in the house combined. Assessors are not
expected to measure skylights precisely, but should attempt to estimate length and width dimensions
each within 6 inches to calculate the window area as accurately as is reasonable. Do not subtract
skylight areas from the roof / attic area.
Panes, Frame Material, Glazing Type – Choose from the dropdown menu choices. If there are multiple
types on a given side, choose the predominant type.
U-Factor and SHGC – If this info is available the “Actual skylight specification” button should be clicked
and these values should be entered instead of the window characteristics. This info can only be found
on the NFRC label attached to the window pane by the manufacturer, or in the new purchase
documentation.
Windows - If the windows are the same on all sides of the house, the window data only needs to be
entered once. If at least one side is different from the others, the window characteristics must be
entered separately for each side of the house. If there are multiple types of windows on the same side,
enter the characteristics of the predominant type for that side. Windows in all conditioned areas must
be included. Do not include any windows in unconditioned areas, such as unconditioned basements or
attics.
Window Area – Enter the total window area from each side of the house. The right and left sides of the
house are determined by street view (facing the front of the house from the street). The glass in entry
doors (excluding storm doors) should be considered as window area, as should entryway sidelights.
Assessors are not expected to measure each window precisely, but should attempt to estimate
horizontal and vertical dimensions each within 6 inches to calculate the window area as accurately as is
reasonable.
Solar Screen – If the windows have solar screens, click ‘Yes’. Solar screens are exterior window screens
specifically engineered to decrease the amount of solar heat coming through the windows, thereby
reducing the home’s cooling load, and are more typically found on homes in the southwest US. Keep in
mind, if the windows on some sides of the house have solar screens but other sides don’t, you’ll need
to click ‘No’ to the “Are the window types the same on all sides?” question and enter the window
characteristics separately for each side.
Panes, Frame Material, Glazing Type – Select from the dropdown menu choices. If there are multiple
types on a side, choose the predominant type. Storm windows should be characterized as an additional
pane only, i.e. a single pane window with a storm window should be characterized as “Double-pane”.
Storm window frame material is irrelevant – enter only the actual window frame material.

Section 5: Systems
System “Efficiency Values” for heating, cooling and hot water equipment should always be entered –
do not use the “Year Installed” field. If you don’t have the documented efficiency value from the unit’s
EnergyGuide label or other documentation, utilize the “Equipment Efficiency” tab in the Assessor
Calculator to determine the appropriate default efficiency value of an appliance. The “Equipment
Efficiency Default Values” chart provides more accurate calculated efficiencies than the Scoring Tool,
since the Scoring Tool significantly de-rates efficiencies when the year installed is entered. To use the
chart you must determine the year of manufacture for most HVAC equipment. If the manufacture date
is not printed on the data plate and is not available from the homeowner’s documentation, it can be
determined from the unit’s serial number on the data plate. Go to www.buildingcenter.org to look up
the serial number code by manufacturer.
Percent of conditioned floor area served by system – enter the percentage of the conditioned floor
area served by the system as a whole number. If there is only one system, enter 100. If there are
multiple systems, the sum of the percentages must equal 100. If there is a second system, scroll down
(past “Ducts”) and click 'Enter a second system'. The screen will expand to provide a second set of data
entry fields for the second system. Calculate or estimate the percentage of the home served by each
system, based on the square footage that each system serves. If there are more than two systems,
combine similar systems and enter the system size-weighted average efficiency, which can be
determined using the “Averaging Calculator” tab of the Assessor Calculator. For example, if a home is
serviced by two heat pumps and one gas furnace, combine the two heat pumps as System 1 and
calculate the weighted average efficiency (based on the efficiency of each heat pump and on the sq. ft.
each unit serves). Enter the gas furnace as System 2.
If the home has two heating systems but only one cooling system serving the whole house, you need to
make a choice as to how you want to enter the systems. If the heating systems are similar in type and
fuel, you can perform a weighted average efficiency calculation for the two heating units and enter
them as one system servicing 100% of the CFA (conditioned floor area). If the two heating systems are
significantly different in type or fuel, you need to enter them as two separate systems. In this case, you
will also need to enter two cooling systems as well (even though the house has only one cooling
system). Enter identical information for the two cooling systems – do not enter “None” for one of the
systems as this is not an accurate assessment and will produce erroneous results.

If wood heat is frequently used as a supplemental heat system, enter it as System 2 and attempt to
characterize how much of the home’s total heating needs the wood heat provides, as a percentage. If
the house has a cooling system that serves the whole house you will need to enter two cooling systems
as well (even though the house has only one cooling system). Enter identical information for two
cooling systems – do not enter “None” for one of the systems as this is not an accurate assessment and
will produce erroneous results.
If the home has a hybrid or dual fuel heat pump with a gas furnace back-up the system should be
entered as two systems:
o System 1: services 80% of the CFA, select Electric Heat Pump for both the heating and
cooling systems, and enter the duct configuration for the whole house.
o System 2: services 20% of the CFA, select Central Gas Furnace for the heating system,
select Central Air Conditioner for the cooling system, and enter the same cooling
efficiency and duct configuration as you did for System 1.
Heating – If there are multiple systems, characterize the two largest systems. When there are more
than two systems, combine the systems that are using the same fuel and calculate a system sizeweighted average efficiency (using one of the “Weighted Average Calculators” in the Assessor
Calculator) for those systems in order to narrow down the total number of systems to two. If there are
more than two dissimilar systems, enter the data for the two largest systems.
Type of Heating System – If the home’s heating system is not represented in the selections, use your
best judgement to select the system that most closely resembles the home’s system. If heat pump or
mini-split heat pump is selected for the Heating System it will automatically be selected for the Cooling
System, although this can be overridden if necessary by clicking on the Cooling System type selections.
If a stand-alone gas stove type heater is part of the heating system, it should be characterized as
“Room (through-the-wall) gas furnace”, and efficiency value should be entered as .65 AFUE.
Heating System Efficiency – It is strongly recommended that the efficiency of the equipment is entered
rather than the year installed.* Gather the information from the equipment labels or from the
homeowner’s documentation. If the efficiency is not documented, use the appropriate efficiency value
from the “Equipment Efficiency Default Values” chart in the Assessor Calculator. The efficiency is
entered as AFUE for combustion heat, HSPF for heat pump, and COP for ground coupled (aka ground
source or geothermal) heat pump (gchp). Do not use the “Installed Year” field, as this will compel the
Scoring Tool to default to a delivery weighted average efficiency for that year, and high efficiency
equipment will incur a significant efficiency penalty. For gchp heating efficiency you must enter the
ARI-330 32F COP rating number, which you can determine for the specific unit by looking it up at
www.ahridirectory.org (you’ll need to enter the unit’s AHRI Certified Reference Number or the unit’s

model number in the search field on the website). *For wood heat (wood stove and pellet stove) and
electric resistance heat (electric furnace and electric baseboard heater) the Tool provides default
efficiencies, so the efficiency/install date fields will be hidden when one of these is chosen.
Combustion Furnace/Boiler efficiency values (AFUE) should not be entered as less than .70 unless you
actually measure it as such. Heat pump efficiency values (HSPF) should not be less than 6.5.
Cooling - If there are multiple systems, characterize the two largest systems. When there are more
than two systems, combine the systems that are using the same fuel and calculate a system sizeweighted average efficiency (using one of the “Weighted Average Calculators” in the Assessor
Calculator) for those systems in order to narrow down the total number of systems to two. If there are
more than two dissimilar systems, enter the data for the two largest systems.
Type of Cooling System – If heat pump or mini-split heat pump is selected for the Heating System it will
automatically be selected for the Cooling System, although this can be overridden if necessary by
clicking on the Cooling System type selections – if there is no cooling system, be sure to change this
field to “None”. When entering efficiency for a heat pump cooling system you must enter the SEER
value – do not enter an HSPF value.
Cooling System Efficiency - It is strongly recommended that the efficiency of the equipment is entered
rather than the year installed. Gather the information from the equipment labels or the homeowner’s
documentation. If the efficiency is not documented, use the appropriate efficiency value from the
“Equipment Efficiency Default Values” chart in the Assessor Calculator. The efficiency is entered as
SEER for central air conditioning or heat pump, and EER for room/window air conditioning or gchp. Do
not use the “Installed Year” field, as this will compel the Scoring Tool to default to a delivery weighted
average efficiency for that year, and high efficiency equipment will incur a significant efficiency
penalty. For gchp cooling efficiency you must enter the ARI-330 77F EER rating number, which you can
determine for the specific unit by looking it up at www.ahridirectory.org (you’ll need to enter the unit’s
AHRI Certified Reference Number or the unit’s model number in the search field on the website). Air
conditioning/heat pump (cooling) efficiency values (SEER) should not be less than 9. If direct
evaporative cooling is selected the Tool will use a default efficiency value, so the efficiency question
and field will be hidden.
Ducts – The duct fields will be hidden when a non-ducted system is chosen (i.e. electric baseboard,
mini-split heat pump, boiler or wood heat) and there is no central air conditioning. For ducts located in
a concrete slab choose “Unvented crawlspace” as the location; insulated: “no”; sealed: “yes”. If the
system does not have ducts but the Tool requires duct entries, choose “Conditioned space” as the
location; insulated: “yes”; sealed: “yes”.

Duct Location – choose the location (see above for exceptions)
Percent in that location – indicate the whole number percent (of the total duct length for the home) in
that location with the same insulation and duct seal characteristics. There are up to 3 duct location
entries available - the sum of the location percentages must equal 100.
Are the ducts insulated/sealed – Answer yes or no based on those ducts referenced in the duct
location entry. Ducts should only be considered sealed and/or insulated if the Assessor has visually
verified them as such, i.e. duct mastic/spray foam/UL-181 tape on joints and insulation on (or in) the
ducts, particularly in unconditioned areas. For ducts located in a concrete slab, choose insulated: “no”;
sealed: “yes”.
Hot Water
Hot Water Type – If there are multiple systems using different fuels, enter the characteristics of the
largest or most predominant system.
Water Heater Efficiency – Always enter the actual efficiency rather than the year installed (entering
year installed is not allowed for electric heat pump water heaters). The Tool will accept an energy
factor as high as 4.00 (for a heat pump water heater). If the energy factor is unknown, use the default
values from the “Equipment Efficiency Default Values” chart in the Assessor Calculator. Do not use the
“Installed Year” field, as this will compel the Scoring Tool to default to a delivery weighted average
efficiency for that year, and high efficiency equipment will incur a significant efficiency penalty. The
energy factor should be rounded to the second decimal. If there are multiple systems using the same
fuel, calculate and enter a system size weighted average efficiency using the “Energy factor – Weighted
Average” calculator in the Assessor Calculator. If there are multiple systems using different fuels, enter
the efficiency of the largest system.
UEF (Uniform Energy Factor) - Water heaters manufactured after June 2017 are rated using UEF
(Uniform Energy Factor), which is printed on the yellow EnergyGuide label. This should be entered into
Home Energy Score Tool by selecting “Yes (UEF)” and then entering the value in the Energy Factor field.
If one of the home’s heating system is a boiler and it provides the domestic hot water as well, select
“Boiler with tankless coil” or “Boiler with indirect tank”, appropriately – no efficiency value is required.
If the home’s water is heated by a gchp desuperheater, the system should be characterized as “Electric
heat pump” (water heater) and the energy factor should be entered as 2.5.
Currently, solar thermal (water heating) systems cannot be accurately modeled by the Scoring Tool. If
the home’s water is heated primarily by a solar thermal system with electric heating back-up, the
system can be characterized as an “Electric heat pump” (water heater), in which case the energy factor

cannot be modeled in the Scoring Tool.
Solar Photovoltaic (PV) System
If the home has a solar photovoltaic system, the “Year installed” and “Direction panels face” must both
be entered. If you know the system’s DC capacity in kilowatts, select “Yes” and enter the value. The
owner may have documentation with this information, which is more accurate than entering the
number of panels. Otherwise, select “No” (the entry box will change from “DC capacity” to “Number

Home Energy Score Definitions
Absorptance – a measure of how much heat from the sun is absorbed by the roof. The number falls
between zero and one. The closer the number is to 1.0, the more energy is absorbed. In climates that
use more air conditioning than heating, it can be beneficial to have a roof with a number less than 0.5.
Air Barrier – the building components that reduce or stop conditioned air from moving between inside
and outside. This is typically the top floor ceiling, the lowest floor, and the walls. To be effective the air
barrier must be continuous and must be in contact with the thermal boundary.
AFUE (Annual Fuel Utilization Efficiency) – the estimated energy efficiency of heating systems that use
fossil fuels. It accounts for all losses related to the actual heating unit.
Base Load – the energy used by the appliances and fixtures in your home other than the heating,
cooling, and hot water systems. Base load includes lighting, entertainment systems, computers,
kitchen appliances, washer & dryer, etc.
Batt – a blanket of insulation that is provided in standard widths and thicknesses.
Blower Door – a large fan, removable door panel and gauges used to measure the degree of air
leakage in a building’s envelope, and also used to locate the leaks in the air barrier.
Btu (British thermal unit) – an international standard unit of measuring energy content or power; one
Btu is the amount of heat needed to raise one pound of water one degree Fahrenheit. 1,000 Btu equals
1 kBtu, and one million Btu (or 1,000 kBtu) equals 1 Mbtu.
Cathedral Ceiling – a sloped ceiling which is either part of or directly attached to the roof rafters, and is
therefore part of the roof assembly. Cathedral ceilings can either be open, with exposed rafters, or
have enclosed rafter cavities. Cathedral ceilings have no attic space. Cathedral ceilings are not the
same as vaulted ceilings (see definition below).
Cellulose Insulation – insulation made from recycled newspapers, cardboard and/or wood waste that
is treated with a fire retardant.
CO (Carbon Monoxide) – a colorless, odorless, deadly gas that can be produced by any equipment that
burns fossil fuels.
COP (Coefficient of Performance) – a measure of the efficiency of a heating or cooling system that
uses electricity as its fuel. The number typically falls between 1 and 10 with 10 being the most efficient.
This is typically used only for ground source heat pumps.
Cooling Load – the maximum amount of heat removal required from the air conditioner when the
outside temperature and humidity are at design conditions.

Dense Pack Insulation – a method of using loose fill insulation (cellulose or fiberglass) to completely fill
a wall, floor, or ceiling cavity enough to significantly reduce air movement. Fibrous insulation (e.g.
fiberglass or cellulose) will not stop air flow, but can reduce it when applied under pressure in an
enclosed cavity.
Design Conditions – the temperature and humidity measurements used to calculate the amount of
heating or cooling capacity needed by the house to maintain comfort. The temperature values are
dependent on how severe the weather typically is in that location.
Desuperheater – A secondary heat exchanger that transfers heat from a gchp heating/cooling system
to the domestic hot water system.
EER (Energy Efficiency Ratio) – a measurement of the energy efficiency of air conditioners. Typically it
is only applied to window or through the wall air conditioners. The number typically falls between 5
and 10 - the higher the number, the better.
Energy Factor – a measure of the efficiency of a water heater. The value typically falls between 0.5 and
1, although the most efficient systems can have an energy factor greater than 2.
Envelope – the part of the house that separates inside from outside. Typically the envelope is
comprised of the walls and windows, the lowest floor, and the ceiling.
Exfiltration – uncontrolled air flow out of the house. This is caused by pressure differences (stack
effect, temperature gradients, and wind) or be mechanically driven (duct leakage). Exfiltration is a
direct cause of infiltration.
Fiberglass – an insulation material made by spinning molten glass.
Heating Load – the maximum amount of heat needed by the house during design conditions.
HSPF (Heating Seasonal Performance Factor) – a measure of the efficiency of an air source heat pump
during the heating season. HSPF is typically between 6 and 12 - the higher the number, the more
efficient the equipment.
HVAC – Heating, Ventilation and Air Conditioning.
Infiltration – the uncontrolled flow of air into the house as a direct result of exfiltration.
Insulation – any material with a relatively high thermal resistance or R-value.
kBtu – equals one thousand Btu.

kWh (kilowatt hour) – a unit of electric energy equal to one thousand watt-hours or 3412 Btu-hrs.
Knee Wall – a wall extending to the roof rafters or trusses, separating unconditioned attic space from
conditioned space.
Mastic – a thick, gooey paste used to seal duct joints.
MBtu – equals one million Btu, or one thousand kBtu.
MWh (megawatt hour) – equals one thousand kWh, or one million watt-hours.
Mechanical Ventilation – the use of a fan to control the amount of air that moves into and out of a
building.
R-value – a measure of a material’s resistance to heat flow - the higher the number, the more resistant
to heat flow and thus the higher the insulation value. R-value is the inverse of U-factor.
Radiant Barrier – typically a shiny material that reflects radiant heat waves (e.g. heat from the sun)
away from the house. This can be beneficial in climates where air conditioning requires more energy
than heating on an annual basis. Radiant barriers have very low R-value.
SEER (Seasonal Energy Efficiency Ratio) – a measurement of the efficiency of a central air conditioner
or the cooling efficiency of a heat pump. The number usually falls between 8 and 20, but can be higher.
The higher the number, the more efficient the equipment.
SHGC (Solar Heat Gain Coefficient) – a measure of how effective a window is at preventing radiant
heat from passing through the glass. The number falls between 0.0 and 1.0 - the lower the number the
more effective the window is.
Thermal boundary – the surfaces of a house that reduce heat movement between the inside and the
outside by the application of insulation. The thermal boundary should be continuous and be in direct
contact with (or be part of) the air barrier.
U-factor – a measure of the ability of a material or combination of materials to transfer heat, often
used to express window efficiency. U-factor is the inverse of the R-value. The U-factor for windows is
usually a decimal less than 1 - the smaller the number, the better the efficiency performance of the
window.
Vaulted Ceiling – a sloped ceiling which is not directly part of or attached to the roof rafters and so is
not part of the roof assembly. Vaulted ceilings have some degree of attic space above them. Vaulted
ceilings are not the same as cathedral ceilings (see definition above).
