I. Introduction
A. Authority
The Energy Independence and
Security Act of 2007 (EISA, Pub. L. 110–
140) requires that DOE establish by
regulation standards for energy
efficiency in manufactured housing.
DOE is directed to base the standards on
the most recent version of the
International Energy Conservation Code
(IECC) and any supplements to that
document, except where DOE finds that
the IECC is not cost-effective, or where
a more stringent standard would be
more cost-effective, based on the impact
of the IECC on the purchase price of
manufactured housing and on total lifecycle construction and operating costs.
See 42 U.S.C. 17071(b)(1).
B. Background
On June 13, 2014, DOE published a
notice of intent to establish a
PO 00000
Frm 00003
Fmt 4702
Sfmt 4702
7551
manufactured housing working group
(MH working group) to discuss and, if
possible, achieve consensus on
recommendations for a proposed rule.
79 FR 33873. On July 16, 2014, the MH
working group was established under
the Appliance Standards and
Rulemaking Federal Advisory
Committee (ASRAC) in accordance with
the Federal Advisory Committee Act
and the Negotiated Rulemaking Act. See
79 FR 41456; 5 U.S.C. 561–570, App. 2.
The MH working group was to consist
of representatives of parties having a
defined stake in the outcome of the
proposed standards, and the group
would consult, as appropriate, with a
range of external experts on technical
issues.
The MH working group consisted of
22 members, including one member
from ASRAC and one DOE
representative. The MH working group
met in-person during six sets of
meetings held August 4–5, August 21–
22, September 9–10, September 22–23,
October 1–2, and October 23–24. See 79
FR 48097 and 79 FR 59154.
On October 31, 2014, the MH working
group reached consensus on energy
efficiency standards in manufactured
housing and assembled its
recommendations for DOE into a term
sheet that was presented to ASRAC. See
EERE–2009–BT–BC–0021–0107. ASRAC
approved the term sheet during an open
meeting on December 1, 2014. As part
of the term sheet, the MH working group
recommended that DOE conduct
additional analysis to inform the
selection of solar heat gain coefficient
(SHGC) requirements in certain climate
zones. See EERE–2009–BT–BC–0021–
0107, p. 3, Recommendation 5. For more
information on the MH working group’s
recommendations, please refer to the
complete term sheet posted in the
public docket. See EERE–2009–BT–BC–
0021–0107.
II. Request for Information and
Comments
A. Solar Heat Gain Coefficient
Sensitivity Analysis
The MH working group did not
recommend a specific SHGC value for
climate zones 1B and 2. See EERE–
2009–BT–BC–0021–0107, p. 2,
Recommendation 3.1 for climate zones.
Instead, the MH working group
requested that DOE complete additional
sensitivity analysis and select the SHGC
based on that data. Specifically, the MH
working group requested that DOE
analyze window fenestration SHGC
values of 0.25, 0.30, and 0.33. In
previous energy simulation analysis,
DOE performed a modeling analysis
E:\FR\FM\11FEP1.SGM
11FEP1
7552
Federal Register / Vol. 80, No. 28 / Wednesday, February 11, 2015 / Proposed Rules
with windows uniformly distributed on
the exterior walls of a manufactured
home. While windows are frequently
concentrated on one side of typical
manufactured homes in practice, a
uniform configuration for the energy
simulation represented the fact that
manufactured homes are sited in a full
range of orientations (east, west, north,
south, etc.). This configuration
effectively calculates a weighted average
energy use for homes facing all
directions. For the sensitivity analysis,
the MH working group requested energy
simulation analysis that places all
windows on a single side of the home,
with windows facing the cardinal
direction that would give SHGC the
greatest impact on energy use. In
response to the MH working group’s
request, DOE completed additional
energy simulation analysis and lifecycle cost (LCC) analysis. For more
information on the MH working group’s
recommendations with regard to SHGC,
please refer to the complete term sheet
posted in the public docket. See EERE–
2009–BT–BC–0021–0107.
For simulation of manufactured
housing energy use, DOE used the
EnergyPlus 5.0 software that was also
used for energy simulation analytical
support during meetings of the MH
working group. EnergyPlus 5.0 is a
detailed whole-building energy
modeling tool that is useful for
simulating the heating, cooling, and
ventilation loads in a building. To
simulate manufactured home energy
use, DOE created a representative
manufactured home using typical
construction assumptions such as
building geometry and framing member
size. These assumptions are the same as
those used for energy simulation during
the MH working group process.
To maximize the impact of SHGC on
energy use, DOE placed all windows on
one side of the representative
manufactured home, with that side
facing west. DOE then generated energy
use values for the three SHGC values in
nine cities (four cities in climate zone
1B and five cities in climate zone 2, as
recommended by the MH working
group) and for two sizes of
manufactured homes (single-section and
double-section).
The LCC analysis calculates the total
cost of ownership savings over a
specified period of time. The total cost
of ownership savings is equal to the
total cost of ownership of a reference
manufactured home minus the total cost
of ownership of a manufactured home
constructed in accordance with DOE’s
proposed standards. The reference home
is modeled to meet the minimum energy
efficiency requirements of the
Department of Housing and Urban
Development Code. See 24 CFR 3280 et
seq. The LCC analysis includes both
operating costs (primarily energy costs)
and purchase cost of the manufactured
home. DOE calculated energy costs
(using the energy simulation results)
and added those to the purchase cost of
the manufactured home, accounting for
differences in the cost of the three
window fenestration types. Regarding
the purchase cost of the standardscompliant manufactured home, only the
cost of window fenestration varied for
each scenario of the SHGC sensitivity
analysis. Other building thermal
envelope components were modeled
(for energy simulation and cost analysis)
as specified in the MH working group
term sheet. See EERE–2009–BT–BC–
0021–0107. DOE calculated the 10-year
total cost of ownership savings for
manufactured housing with window
fenestration SHGC of 0.25, 0.30, and
0.33. The 10-year analysis period
represents the total cost of ownership
for the first owner of the manufactured
home and assumes the first owner keeps
the manufactured home for 10 years. For
more information with regard to DOE’s
LCC analysis, please refer to the
complete term sheet posted in the
public docket. See EERE–2009–BT–BC–
0021–0107.
The energy simulation analysis
indicated SHGC of 0.25 had the lowest
energy use and SHGC of 0.33 had the
highest energy use. Based on industry
input collected from the MH working
group, DOE assigned single-section
manufactured home window
fenestration prices (retail prices before
sales tax) of $1446, $1389, and $1355 for
SHGC of 0.25, 0.30, and 0.33,
respectively.
The LCC analysis, based on the energy
simulation results and window
fenestration prices, determined that
SHGC of 0.30 provided the largest 10year cost of ownership savings in all
four cities analyzed in climate zone 1B
and in four of the five cities analyzed in
climate zone 2. SHGC of 0.33 had the
second most 10-year cost-of-ownership
savings, and SHGC of 0.25 had the least
10-year cost-of-ownership savings.
These 10-year cost-of-ownership savings
results are listed in Table II.1.

III. Submission of Comments
I. Introduction
A. Authority
The Energy Independence and Security Act of 2007 (EISA, Pub. L.
110-140) requires that DOE establish by regulation standards for energy
efficiency in manufactured housing. DOE is directed to base the
standards on the most recent version of the International Energy
Conservation Code (IECC) and any supplements to that document, except
where DOE finds that the IECC is not cost-effective, or where a more
stringent standard would be more cost-effective, based on the impact of
the IECC on the purchase price of manufactured housing and on total
life-cycle construction and operating costs. See 42 U.S.C. 17071(b)(1).
B. Background
On June 13, 2014, DOE published a notice of intent to establish a
manufactured housing working group (MH working group) to discuss and,
if possible, achieve consensus on recommendations for a proposed rule.
79 FR 33873. On July 16, 2014, the MH working group was established
under the Appliance Standards and Rulemaking Federal Advisory Committee
(ASRAC) in accordance with the Federal Advisory Committee Act and the
Negotiated Rulemaking Act. See 79 FR 41456; 5 U.S.C. 561-570, App. 2.
The MH working group was to consist of representatives of parties
having a defined stake in the outcome of the proposed standards, and
the group would consult, as appropriate, with a range of external
experts on technical issues.
The MH working group consisted of 22 members, including one member
from ASRAC and one DOE representative. The MH working group met in-
person during six sets of meetings held August 4-5, August 21-22,
September 9-10, September 22-23, October 1-2, and October 23-24. See 79
FR 48097 and 79 FR 59154.
On October 31, 2014, the MH working group reached consensus on
energy efficiency standards in manufactured housing and assembled its
recommendations for DOE into a term sheet that was presented to ASRAC.
See EERE-2009-BT-BC-0021-0107. ASRAC approved the term sheet during an
open meeting on December 1, 2014. As part of the term sheet, the MH
working group recommended that DOE conduct additional analysis to
inform the selection of solar heat gain coefficient (SHGC) requirements
in certain climate zones. See EERE-2009-BT-BC-0021-0107, p. 3,
Recommendation 5. For more information on the MH working group's
recommendations, please refer to the complete term sheet posted in the
public docket. See EERE-2009-BT-BC-0021-0107.
II. Request for Information and Comments
A. Solar Heat Gain Coefficient Sensitivity Analysis
The MH working group did not recommend a specific SHGC value for
climate zones 1B and 2. See EERE-2009-BT-BC-0021-0107, p. 2,
Recommendation 3.1 for climate zones. Instead, the MH working group
requested that DOE complete additional sensitivity analysis and select
the SHGC based on that data. Specifically, the MH working group
requested that DOE analyze window fenestration SHGC values of 0.25,
0.30, and 0.33. In previous energy simulation analysis, DOE performed a
modeling analysis
[[Page 7552]]
with windows uniformly distributed on the exterior walls of a
manufactured home. While windows are frequently concentrated on one
side of typical manufactured homes in practice, a uniform configuration
for the energy simulation represented the fact that manufactured homes
are sited in a full range of orientations (east, west, north, south,
etc.). This configuration effectively calculates a weighted average
energy use for homes facing all directions. For the sensitivity
analysis, the MH working group requested energy simulation analysis
that places all windows on a single side of the home, with windows
facing the cardinal direction that would give SHGC the greatest impact
on energy use. In response to the MH working group's request, DOE
completed additional energy simulation analysis and life-cycle cost
(LCC) analysis. For more information on the MH working group's
recommendations with regard to SHGC, please refer to the complete term
sheet posted in the public docket. See EERE-2009-BT-BC-0021-0107.
For simulation of manufactured housing energy use, DOE used the
EnergyPlus 5.0 software that was also used for energy simulation
analytical support during meetings of the MH working group. EnergyPlus
5.0 is a detailed whole-building energy modeling tool that is useful
for simulating the heating, cooling, and ventilation loads in a
building. To simulate manufactured home energy use, DOE created a
representative manufactured home using typical construction assumptions
such as building geometry and framing member size. These assumptions
are the same as those used for energy simulation during the MH working
group process.
To maximize the impact of SHGC on energy use, DOE placed all
windows on one side of the representative manufactured home, with that
side facing west. DOE then generated energy use values for the three
SHGC values in nine cities (four cities in climate zone 1B and five
cities in climate zone 2, as recommended by the MH working group) and
for two sizes of manufactured homes (single-section and double-
section).
The LCC analysis calculates the total cost of ownership savings
over a specified period of time. The total cost of ownership savings is
equal to the total cost of ownership of a reference manufactured home
minus the total cost of ownership of a manufactured home constructed in
accordance with DOE's proposed standards. The reference home is modeled
to meet the minimum energy efficiency requirements of the Department of
Housing and Urban Development Code. See 24 CFR 3280 et seq. The LCC
analysis includes both operating costs (primarily energy costs) and
purchase cost of the manufactured home. DOE calculated energy costs
(using the energy simulation results) and added those to the purchase
cost of the manufactured home, accounting for differences in the cost
of the three window fenestration types. Regarding the purchase cost of
the standards-compliant manufactured home, only the cost of window
fenestration varied for each scenario of the SHGC sensitivity analysis.
Other building thermal envelope components were modeled (for energy
simulation and cost analysis) as specified in the MH working group term
sheet. See EERE-2009-BT-BC-0021-0107. DOE calculated the 10-year total
cost of ownership savings for manufactured housing with window
fenestration SHGC of 0.25, 0.30, and 0.33. The 10-year analysis period
represents the total cost of ownership for the first owner of the
manufactured home and assumes the first owner keeps the manufactured
home for 10 years. For more information with regard to DOE's LCC
analysis, please refer to the complete term sheet posted in the public
docket. See EERE-2009-BT-BC-0021-0107.
The energy simulation analysis indicated SHGC of 0.25 had the
lowest energy use and SHGC of 0.33 had the highest energy use. Based on
industry input collected from the MH working group, DOE assigned
single-section manufactured home window fenestration prices (retail
prices before sales tax) of $1446, $1389, and $1355 for SHGC of 0.25,
0.30, and 0.33, respectively.
The LCC analysis, based on the energy simulation results and window
fenestration prices, determined that SHGC of 0.30 provided the largest
10-year cost of ownership savings in all four cities analyzed in
climate zone 1B and in four of the five cities analyzed in climate zone
2. SHGC of 0.33 had the second most 10-year cost-of-ownership savings,
and SHGC of 0.25 had the least 10-year cost-of-ownership savings. These
10-year cost-of-ownership savings results are listed in Table II.1.

Based on the 10-year cost-of-ownership savings results, DOE
concluded that an SHGC requirement of 0.30 would lead to the most cost-
effective manufactured home for both climate zones 1B and 2. DOE
requests comment on whether to include an SHGC requirement of 0.30 for
climate zones 1B and 2 in development of the proposed rule.
B. Window Fenestration Energy Efficiency Programs for Manufactured
Housing
DOE is interested in receiving information that relates to window
fenestration manufacturing and programs available to the manufactured
housing industry. DOE requests comment on several topics related to
window fenestration efficiency and manufactured homes:
1. DOE is interested in receiving additional information on
existing
[[Page 7553]]
window fenestration labeling programs available to the manufactured
housing industry that may label the whole window or individual
insulated glass units (IGUs).
2. DOE requests comment on the potential challenges related to
determining the energy efficiency of IGUs in manufactured homes or
insuring the efficiency of IGUs in manufactured homes in connection
with voluntary window fenestration labeling programs.
3. DOE requests comment on any other issues related to the
regulation of window fenestration in manufactured housing.
III. Submission of Comments
DOE invites all interested parties to submit in writing by March
13, 2015, comments and information on matters addressed in this RFI.
After the close of the comment period, DOE will consider the public
comments in development of the proposed rule.
DOE considers public participation to be a very important part of
the process for developing energy efficiency standards for manufactured
housing. DOE actively encourages the participation and interaction of
the public during the comment period at each stage of the rulemaking
process. Interactions with and between members of the public provide a
balanced discussion of the issues and assist DOE in the rulemaking
process. Anyone who wishes to be added to the DOE mailing list to
receive future notices and information about this rulemaking should
contact Ms. Brenda Edwards at (202) 586-2945, or via email at
Brenda.Edwards@ee.doe.gov.
