SECTION 1. PURPOSE
This notice clarifies and supersedes Notice 2006-28, 2006-11 I.R.B. 628, as
updated by Announcement 2006-88, 2006-46 I.R.B. 910. Notice 2006-28, as updated,
provided guidance regarding the calculation of heating and cooling energy consumption
for purposes of determining the eligibility of a manufactured home for the New Energy
Efficient Home Credit under Internal Revenue Code § 45L. Notice 2006-28 also
provided guidance relating to the public list of software programs that may be used to
calculate energy consumption. Guidance relating to dwelling units other than
manufactured homes is provided in Notice 2008-35.
This notice supersedes Notice 2006-28 by substantially republishing the
guidance contained in that publication. This notice clarifies the meaning of the terms
equivalent rating network and eligible contractor, and permits calculation procedures
other than those identified in Notice 2006-28 to be used to calculate energy
consumption. Finally, this notice clarifies the process for removing software from the list
of approved software and reflects the extension of the tax credit through December 31,
2008.

SECTION 2. BACKGROUND
.01 In General. Section 45L provides a credit to an eligible contractor who
constructs a qualified energy efficient home. For qualified energy efficient homes that
are manufactured homes, the amount of the credit is $1,000 or $2,000, depending on
the energy savings that are achieved. A manufactured home qualifies for the credit if:
(1) It is located in the United States;
(2) Its construction is substantially completed after August 8, 2005;
(3) It meets the energy saving requirements of § 45L(c)(2) or (3); and
(4) It is acquired, directly or indirectly, from the eligible contractor after
December 31, 2005, and before January 1, 2009, for use as a residence.
.02 Energy Saving Requirements
. To meet the energy saving requirements of
§ 45L(c)(2) or (3), a manufactured home must meet one of the following standards:
(1) To meet the energy saving requirements of § 45L(c)(2) and qualify for
the $2,000 credit, a manufactured home must be certified to provide a level of heating
and cooling energy consumption that is at least 50 percent below that of a reference
dwelling unit constructed in accordance with the standards of § 404 of the 2004
Supplement to the 2003 International Energy Conservation Code (2004 IECC
Supplement), and to have building envelope component improvements that provide for
a level of heating and cooling energy consumption that is at least 10 percent below that
of a reference dwelling unit (see section 3 of this Notice).
(2) To meet the energy saving requirements of § 45L(c)(3) and qualify for
the $1,000 credit, a manufactured home must either--

3
(a) be certified to provide a level of heating and cooling energy
consumption that is at least 30 percent below that of a reference dwelling unit
constructed in accordance with the standards of § 404 of the 2004 IECC Supplement,
and to have building envelope component improvements that provide for a level of
heating and cooling energy consumption that is at least 10 percent below that of a
reference dwelling unit; or
(b) meet the current requirements established by the Administrator
of the Environmental Protection Agency under the ENERGY STAR
®
Labeled Homes
Program in effect on the date construction is substantially completed (see section 4 of
this Notice).
.03 Calculation Procedures
. For purposes of section 2.02 of this notice, heating
and cooling energy consumption must be calculated in accordance with the procedures
prescribed in Residential Energy Services Network (RESNET) Publication No. 05-001
(Nov. 17, 2005) or No. 06-001 (June 1, 2006) or in accordance with an equivalent
calculation procedure.
.04 Acquired from Eligible Contractor
. A qualified energy efficient manufactured
home is acquired directly from an eligible contractor for use as a residence if the person
that produced the manufactured home sells or leases the manufactured home to
another person for use as a residence. A qualified energy efficient manufactured home
is acquired indirectly from an eligible contractor for use as a residence if the person that
produced the manufactured home sells the manufactured home to an intermediary and
the intermediary (or the last of multiple intermediaries) sells or leases the manufactured
home to another person for use as a residence. A qualified energy efficient

4
manufactured home is not acquired from an eligible contractor if the person that
produced the manufactured home retains the manufactured home for use as a
residence. For example, a qualified energy efficient manufactured home is acquired
from an eligible contractor in the following situations:
(1) A person produces a qualified energy efficient manufactured home
and then sells the manufactured home to the homeowner.
(2) A person produces a qualified energy efficient manufactured home
and then leases the manufactured home to the lessee or tenant.
(3) A person hires a third party contractor to produce a qualified energy
efficient manufactured home and then sells the manufactured home to the homeowner.
(See section 5.01(5) of this notice for guidance regarding the person treated as the
eligible contractor in this case.)
(4) A person that produces a manufactured home sells the home to a
dealer of manufactured homes and the dealer sells the manufactured home to another
person for use as a residence. (See section 7.01 of this notice for a rule permitting an
eligible contractor to rely on a dealer’s statement concerning a sale by the dealer.)
SECTION 3. REQUIREMENTS TO CLAIM THE $2,000 CREDIT
An eligible contractor must obtain the certification required under § 45L(c)(2) with
respect to a manufactured home from an eligible certifier before claiming the $2,000
energy efficient home credit with respect to the manufactured home. An eligible
contractor is not required to file the certification with the return on which the credit is
claimed. However, § 1.6001-1(a) of the Income Tax Regulations requires that
taxpayers maintain such books and records as are sufficient to establish the entitlement

5
to, and amount of, any credit claimed by the taxpayer. Accordingly, an eligible
contractor claiming a $2,000 credit under § 45L should retain the certification as part of
the eligible contractor’s records to satisfy this requirement. The certification will be
treated as satisfying the requirements of § 45L(c)(2) if all construction has been
performed in a manner consistent with the design specifications provided to the eligible
certifier and the certification contains all of the following:
.01 The name, address, and telephone number of the eligible certifier.
.02 The manufactured home’s serial or other identification number.
.03 A statement by the eligible certifier that--
(1) The manufactured home has a projected level of annual heating and
cooling energy consumption that is at least 50 percent below the annual level of heating
and cooling energy consumption of a reference dwelling unit in the same climate zone;
(2) Building envelope component improvements alone account for a level
of annual heating and cooling energy consumption that is at least 10 percent below the
annual level of heating and cooling energy consumption of a reference dwelling unit in
the same climate zone; and
(3) Heating and cooling energy consumption have been calculated in the
manner prescribed in section 2.03 of this notice.
.04 A statement by the eligible certifier that inspections of the manufactured
home (or of other manufactured homes under the sampling protocol described below)
performed by the eligible certifier after installation on the permanent site have confirmed
that such heating and cooling energy consumption complies with the design
specifications provided to the eligible certifier. With respect to manufacturers that

6
produce at least 85 homes during a twelve-month period, the eligible certifier may use
the sampling protocol found in the current standards of the ENERGY STAR

.02 Energy Star Homes
. An eligible contractor may claim the $1,000 energy
efficient home credit with respect to a manufactured home by meeting the applicable
certification requirements established by the Administrator of the Environmental
Protection Agency under the ENERGY STAR
®
Labeled Homes Program in effect on the
date construction is substantially completed.
SECTION 5. DEFINITIONS
.01 The following definitions apply for purposes of this notice:
(1) Building envelope components are basement walls, exterior walls,
floor, roof, and any other building element that encloses conditioned space, including
any boundary between conditioned space and unconditioned space.
(2) A climate zone is a geographical area within which all locations have
similar long-term climate conditions as defined in Chapter 3 of the 2004 IECC
Supplement.
(3) A dwelling unit is a single unit providing complete independent living
facilities for one or more persons, including permanent provisions for living, sleeping,
eating, cooking, and sanitation, within a building that is not more than three stories

10
above grade in height.
(4) An eligible certifier is a person that is not related (within the meaning
of § 45(e)(4)) to the eligible contractor and has been accredited or otherwise authorized
by RESNET (or an equivalent rating network) to use energy performance measurement
methods approved by RESNET (or the equivalent rating network). An employee or
other representative of a utility or local building regulatory authority qualifies as an
eligible certifier if the employee or representative has been accredited or otherwise
authorized by RESNET (or an equivalent rating network) to use the approved energy
performance measurement methods.
(5) An eligible contractor, in the case of a qualified energy efficient home
that is a manufactured home, is the person that produced the manufactured home. A
person must own and have a basis in the qualified energy efficient manufactured home
during its production to qualify as an eligible contractor with respect to the manufactured
home. For example, in the situation described in section 2.04(3) of this notice, if the
person that hires the third party contractor to produce the manufactured home owns and
has the basis in the home during its construction, the person that hires the third party
contractor is the eligible contractor and the third party contractor is not an eligible
contractor.
(6) An equivalent calculation procedure is a procedure that produces
results comparable to the results obtained under the procedures prescribed in
Residential Energy Services Network (RESNET) Publication No. 05-001 (Nov.
17, 2005) or No. 06-001 (June 1, 2006).

11
(7) An equivalent rating network includes, in a state that has established
energy efficiency standards under which a dwelling unit is required to achieve a
specified aggregate level of heating and cooling energy consumption for any purpose
(including compliance with building codes or eligibility for a state grant or tax credit), the
state agency administering those standards. Thus, if the agency has accredited or
otherwise authorized a person to use energy performance measurement methods
approved by the agency for use in determining whether the state’s energy
efficiency standards are satisfied, the person so accredited or authorized qualifies as an
eligible certifier.
(8) A manufactured home is a dwelling unit constructed in accordance
with the Federal Manufactured Home Construction and Safety Standards
(24 C.F.R. 3280).
(9) A qualified energy efficient manufactured home is a dwelling unit that
qualifies for the credit under section 45L. See section 2.01 of this notice for the
requirements that a dwelling unit must satisfy to qualify for the credit.
(10) A reference dwelling unit is a dwelling unit that is similar in technical
specifications and design to the manufactured home produced by the eligible contractor
except that--
(a) The reference dwelling unit is constructed in accordance with
the minimum standards of Chapter 4 of the 2004 IECC Supplement;
(b) The reference dwelling unit’s air conditioners have a Seasonal
Energy Efficiency Ratio (SEER) of 13, measured in accordance with 10 C.F.R.
430.23(m); and

12
(c) The reference dwelling unit’s heat pumps have a SEER of 13
and a Heating Seasonal Performance Factor (HSPF) of 7.7, measured in accordance
with 10 C.F.R. 430.23(m).

. In the case of a manufactured home sold by an eligible
contractor to a dealer of manufactured homes, the eligible contractor may rely on a
statement by the dealer to establish the date on which a manufactured home is
acquired, that it is located in the United States, and that it is acquired for use as a
residence. An eligible contractor is not required to file the statement with the return on
which the credit is claimed. However, § 1.6001-1(a) of the Income Tax Regulations
requires that taxpayers maintain such books and records as are sufficient to establish
the entitlement to, and amount of, any credit claimed by the taxpayer. Accordingly, an

15
eligible contractor claiming a credit under § 45L should retain the statement as part of
its records to satisfy this requirement, and is not entitled to rely on the statement unless
the statement is so retained.
.02 Content of Statement. The eligible contractor may not rely on the statement
by the dealer unless the statement specifies the date of the retail sale of the
manufactured home, that the dealer delivered the manufactured home to the purchaser
at an address in the United States, and that the dealer has no knowledge of any
information suggesting that the purchaser will use the manufactured home other than as
a residence. The statement must also contain the following information:
(1) The name, address, and telephone number of the dealer.
(2) A declaration, applicable to the statement made by the dealer and any
