Abstract

The American Recovery and Reinvestment Act of 2009 provides $4.3 billion for the Race to the Top Fund (referred to in the statute as the State Incentive Grant Fund). This is a competitive grant program. The purpose of the program is to encourage and reward States that are creating the
conditions for education innovation and reform; achieving significant improvement in student outcomes, including making substantial gains in student achievement, closing achievement gaps, improving high school graduation rates, and ensuring student preparation for success in college and careers; and implementing ambitious plans in four core education reform areas: (a) Adopting internationally-benchmarked standards and assessments that prepare students for success in college and the workplace; (b) building data systems
that measure student success and inform teachers and principals in how they can improve their practices; (c) increasing teacher effectiveness and achieving equity in teacher distribution;and (d) turning around our lowestachieving schools.

The U.S. Department of Education (the Department) will collect this data from the 12 Race to the Top grantee states to inform its review of grantee implementation, outcomes, oversight, and accountability. The Department will use these forms to inform on-site visits, ‘‘stocktake’’ meetings with Implementation and Support Unit leadership at the Department, and annual reports for individual grantees and the grant program as a whole.

In order to allow for a comprehensive program review of the Race to the Top grantees, we are requesting a three-year
clearance with this form.

**SUMMARY :**  The Department of Energy (DOE or Department) has determined
that the 2010 edition of the Energy Standard for Buildings, Except Low-Rise Residential Buildings, American National Standards Institute (ANSI)/ American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Illuminating Engineering Society of North America (IESNA) Standard 90.1–2010, (Standard 90.1–2010 or the 2010 edition) would achieve greater energy efficiency in buildings subject to the code, than the 2007 edition (Standard 90.1–2007 or the 2007 edition). Also, DOE has determined that the quantitative analysis of the energy consumption of buildings built to Standard 90.1–2010, as compared with buildings built to Standard 90.1–2007, indicates national source energy savings of approximately 18.2 percent of commercial building energy consumption. Additionally, DOE has determined site energy savings are estimated to be approximately 18.5 percent. Upon publication of this affirmative final determination, States are required to certify that they have reviewed the provisions of their commercial building code regarding energy efficiency, and as necessary, updated their code to meet or exceed Standard 90.1–2010. Additionally, this notice provides guidance to States on Certifications, and Requests for
Extensions of Deadlines for Certification

A. Statutory Requirements

Title III of the Energy Conservation and Production Act, as amended (ECPA), establishes requirements for the


### 64905 Federal Register / Vol. 76, No. 202 / Wednesday, October 19, 2011 / Notices

Building Energy Efficiency Standards Program. (42 U.S.C. 6831 et seq. ) Section 304(b), as amended, of ECPA provides that whenever the ANSI/
ASHRAE/IESNA Standard 90.1–1989 (Standard 90.1–1989 or 1989 edition), or any successor to that code, is revised, the Secretary must make a determination, not later than 12 months after such revision, whether the revised code would improve energy efficiency in commercial buildings and must publish notice of such determination in
the Federal Register . (42 U.S.C. 6833 (b)(2)(A)) The Secretary may determine
that the revision of Standard 90.1–1989 or any successor thereof, improves the level of energy efficiency in commercial buildings. If so, then not later than two years after the date of the publication of such affirmative determination, each State is required to certify that it has reviewed and updated the provisions of its commercial building code regarding energy efficiency with respect to the revised or successor code. (42 U.S.C. 6833(b)(2)(B)(i)) The State must include
in its certification a demonstration that the provisions of its commercial building code, regarding energy efficiency, meet or exceed the revised standard. (42 U.S.C. 6833(b)(2)(B)(i))

If the Secretary makes a determination
that the revised standard will not improve energy efficiency in commercial buildings, State commercial
codes must meet or exceed the last revised standard for which the Secretary has made a positive determination. (42 U.S.C. 6833(b)(2)(B)(ii)). On July 20, 2011, the DOE published a
determination in the Federal Register updating the reference code to Standard 90.1–2007. See 76 FR 43287 (July 20, 2011).

ECPA also requires the Secretary to permit extensions of the deadlines for
the State certification if a State can demonstrate that it has made a good faith effort to comply with the requirements of section 304(c) of ECPA and that it has made significant progress in doing so. (42 U.S.C. 6833(c))

B. Background

1. Publication of Standard 90.1–2010

ASHRAE and the IESNA approved the publication of the 2010 edition of Energy Standard for Buildings Except Low-rise Residential Buildings, in October 2010.

The Standard was developed under ANSI-approved consensus standard procedures. Standard 90.1 is under continuous maintenance by a Standing Standard Project Committee (SSPC) for
which the ASHRAE Standard
Committee has established a documented program for regular publication of addenda or revisions, including procedures for timely, documented, consensus action on requests for change to any part of the standard. ANSI approves addenda prior to their publication by ASHRAE and IESNA and prior to their inclusion in a
new version of Standard 90.1. ANSI approved the final addendum for inclusion in Standard 90.1–2010 on July 24, 2010. Appeals were made to several addenda and the results of the appeals process were not final until October 15, 2010. The 2010 edition was published on October 28, 2010.

2. Preliminary Determination

In arriving at a preliminary determination, DOE first reviewed all significant changes between the 2010
edition and the 2007 edition. Standard 90.1 is complex and covers a broad spectrum of the energy related components and systems in buildings ranging from simple storage buildings to complex hospitals and laboratories. The size of buildings addressed range from those smaller than single family homes to the largest buildings in the world. The approach to development of the
standard used in the 2010 edition was not changed from that used for the 2007 edition, with no changes to the scope or the way components are defined. DOE preliminarily determined that because no significant changes were made to the structure, scope, or component definitions of Standard 90.1–2007, a similar methodology used for the analysis of Standard 90.1–2007 could be utilized for the analysis of Standard 90.1–2010, consisting of a qualitative comparison of the textual changes to requirements in Standard 90.1–2010 from Standard 90.1–2007, and a quantitative estimate of the energy savings developed from whole building
simulations of a standard set of buildings constructed to both Standards over a range of U.S. climates. DOE used an extension of the procedure used for
the Standard 90.1–2007 determination for the quantitative estimate of energy savings. The extension was that additional building types were added to the analysis. DOE used the same simulation tool and data for weighing the results by building type and climate
as used for the 90.1–2007
determination.

A detailed discussion of the analysis methodology, which was subject to public comment in 2010 and 2011, can be found in the Notice of Preliminary
Determination for Standard 90.1–2007 and in the Notice of Preliminary
Determination for Standard 90.1–2010. 75 FR 54117 (Sept. 3, 2010) and 76 FR 43299 (July 20, 2011) respectively.

3. Public Comments Regarding the Preliminary Determination

DOE accepted public comments on the preliminary determination for Standard 90.1–2010 until August 19,
2011. DOE received submissions from a
total of six different entities.

The Edison Electric Institute (EEI) submitted a written comment (Docket No. EERE–2010–BT–DET–0050–0002, pgs. 1–3) supporting the preliminary determination while stating the following four issues: (1) DOE should only use the results from its site energy analysis and its energy cost analysis to make its final determination, and not report the source energy analysis results in the final determination, (2) the energy savings, or at least a portion of the estimated energy savings, from addenda that include new federal energy efficiency standards or provide updates to energy efficiency standards should be incorporated into the final determination analysis, (3) EEI would request that the information about the impact of addendum ‘‘bu’’ be included in the final determination notice, and (4) in terms of primary energy associated with electricity, the value in
this notice is overstated and that DOE
should use a more realistic ratio for electricity in its estimates.

In regards to EEI’s first comment, the Department still believes that despite the fact that the source energy analysis results are estimates, it is important to the discussion of global resources and environmental issues to report them. Source energy (or primary energy) addresses the energy needed to deliver energy to the building in addition to the energy used at the building and thus provides a more complete view of the total energy expenditure used by a building than site energy. However, DOE realizes that site energy is the energy that typically appears on utility bills and that is seen by the consumer. DOE also realizes that it is energy cost (as shown on energy bills) to which many consumers react. It is for this reason that DOE provides all three metrics—site energy, source energy, and energy cost—in its determinations.

EEI’s second comment is in reference to the fact that the Department does not include the impact from new or updated federal energy efficiency standards in its determination of energy savings. For the quantitative analysis performed for the 90.1–2010 preliminary determination (http://www.energycodes.gov/status/ documents/ QuantitativeAnalysisReport901- 2010Determination.pdf ), DOE


### 64906 Federal Register / Vol. 76, No. 202 / Wednesday, October 19, 2011 / Notices

incorporated only addenda that modified the prescriptive requirements of the Standard. New or updated federal efficiency standards are not independent requirements of the standard, but rather reflections of Federal manufacturing requirements. In specific circumstances, particularly with regard to requirements for certain heating, ventilation, and air conditioning (HVAC) equipment,
addenda to Standard 90.1–2010 reflect changes to national manufacturing standards previously developed by DOE or enacted independently through Federal legislation. The energy savings
that are attributable to these national manufacturing standards would accrue
no matter what version of Standard 90.1 is considered and regardless of whether they are reflected in the text of the Standards, therefore DOE has not incorporated these as changes contributing to energy savings for the purpose of the Determination.

EEI’s third comment requests that information regarding the impact of
addendum ‘‘bu’’ be included in the final
determination. Addendum ‘‘bu’’ added equipment efficiency requirements for mechanical equipment serving computer rooms, however none of the prototype building models that DOE
uses in its simulations have data centers and therefore the quantifiable impact of this addendum was not captured. DOE does note that the impact of addendum ‘‘bu’’ is captured in the qualitative, or text comparison analysis, where addendum ‘‘bu’’ is listed as a major positive and noted as a new efficiency requirement. When the prototype building models used in this determination were developed by DOE and later reviewed by ASHRAE, no data
center models were included because at that point Standard 90.1 did not include efficiency requirements related to data
centers. DOE did not add data centers to the prototype building models for this determination because the quantitative impact of this addendum would not change the fact that this is a positive final determination of energy savings. DOE is considering adding data centers to the prototype building models for
future determinations.

EEI’s final comment suggests that DOE use a more realistic electricity ratio for determining primary energy associated with electricity production by crediting renewable energy production on the primary side of generation and on the on-site/delivered side of electricity consumption. The Department has chosen to be consistent within their energy analyses by using Energy Information Administration’s (EIA) data and conversion factors solely and by choosing not to mix and match conversion factors. DOE recognizes that
these conversion factors are estimates and that some types of utility energy inputs do not have known conversion factors and other inputs have multiple generally accepted conversion factors. The Department has chosen not to subtract primary renewable energy from the delivered electricity losses value because renewable energy generated as primary energy is still subject to losses in the delivery process to the site. Also,
DOE has chosen not to add on-site generated renewable energy to the delivered electricity value when determining the electricity ratio because on-site generated renewable energy is not subject to the losses that are incurred when delivering primary energy from the plant to the site. Therefore the delivered electricity and delivered electricity loss values used in the preliminary determination are the
same values used in this final determination and yield the electricity ratio of 3.2, explained on page 31–32 of this notice, for converting how much primary (source) electricity is required per unit of site required electricity.

The Gas Technology Institute (GTI) submitted a written comment (Docket No. EERE–2010–BT–DET–0050–0005, pg. 1) stating that it supports the analysis and states that until ASHRAE
90.1 addresses issues related to full fuelcycle energy metrics and a single baseline building budget, the DOE preliminary determination is incomplete and misleading.

The Department’s preliminary
determination does estimate source energy metrics, and DOE has not chosen to use a single baseline building budget
because there are a multitude of building types with far different operating requirements and accompanying energy needs. A single baseline building budget would penalize certain building types while aiding other building types depending on how far away their respective baseline budgets were from a single average baseline budget.

DOE also notes that while DOE has recently issued a notice of proposed policy (NOPP) related to full-fuel-cycle analysis for appliance and equipment standards (76 FR 51281, Docket No. EERE–2010–BT–NOA–0028, ‘‘Energy Conservation Program for Consumer
Products and Certain Commercial and Industrial Equipment: Statement of Policy for Adopting Full-Fuel-Cycle Analyses Into Energy Conservation Standards Program’’), this policy was not proposed for application to building energy codes and standards such as Standard 90.1. This policy was a direct offshoot of the National Academy of Sciences report discussed in conjunction with the comment below from Laclede Gas Company. DOE notes
that GTI’s comment takes issue with
standard 90.1. DOE’s role in determinations is to compare the latest
version of Standard 90.1 with the previous version and to determine if the latest version improves the level of energy efficiency in commercial buildings over the previous version. While DOE is a participant in the Standard 90.1 development process,
DOE does not control the content of
Standard 90.1.

The American Gas Association submitted a written comment (Docket No. EERE–2010–BT–DET–0050–0004, pg. 1) stating that the performance requirements for commercial electric storage water heaters greater then 12kW appear to be less stringent than the current federal minimum efficiency requirements for this class of water
heaters.

DOE acknowledges the discrepancy
between Federal standards for commercial electric storage water heaters and the requirements for this equipment in Standard 90.1–2010. For the purposes of this determination the performance requirements for commercial electric storage water heaters greater than 12kW in ASHRAE 90.1–2010 are not applicable as this determination is only concerned with
whether the 90.1–2010 version improves the level of energy efficiency in commercial buildings compared to the 2007 version of 90.1, and the performance requirements of this equipment did not change from the
2007 to 2010 version.

The Laclede Gas Company submitted a written comment (Docket No. EERE– 2010–BT–DET–0050–0007, pgs. 1–5) stating the following three issues: (1)
Laclede contends there is a conflict of
interest because DOE evaluates new versions of the ASHRAE 90.1 through
its Pacific Northwest National Lab (PNNL), the staff of which participate in ASHRAE committees; (2) Laclede objects ‘‘to the site-based energy efficiency metric because it does not fulfill the ‘scientific integrity’ objectives as ordered by the Presidential Scientific Integrity Memorandum of March 9,

2009 ’’; and (3) Laclede is concerned that
‘‘DOE has limited its ‘Statement of Policy’ for implementing the National Academy of Sciences (NAS) conclusions to the minimum efficiency standards of appliances. Laclede contends that the NAS conclusions should also apply to building efficiency standards.’’

In response to Laclede’s first issue, DOE acknowledges that staff members at


### 64907 Federal Register / Vol. 76, No. 202 / Wednesday, October 19, 2011 / Notices

PNNL participate in ASHRAE. However, the determination analyses were reviewed by DOE management.

In response to Laclede’s second issue,
DOE believes that its determination on
Standard 90.1–2010 has indeed followed the requirements of the
Presidential Memorandum on Scientific Integrity. DOE has subjected the scientific and technological information
it considered in this determination to well-established scientific processes and DOE made available to the public the scientific and technological findings
and conclusions considered or relied on in this final determination by way of the preliminary determination and public comment period. DOE provides all three metrics—site energy, source energy, and energy cost—in its determinations. DOE does not mandate energy efficiency standards which give electric resistance heat an efficiency advantage over natural gas. DOE’s role in determinations is to compare the latest
version of Standard 90.1 with the previous version and to determine if the latest version improves the level of energy efficiency in commercial buildings over the previous version.

In response to Laclede’s third issue, DOE interprets the phrase ‘‘NAS
conclusions’’ to refer to the National Academy of Sciences (NAS) report entitled ‘‘Review of Site (Point-of-Use) and Full-Fuel-Cycle Measurement Approaches to DOE/EERE Building Appliance Energy-Efficiency Standards—Letter Report (2009) (available at http://books.nap.edu/ openbook.php?record

_id=12670& page=1 ). DOE has not limited its ‘‘Statement of Policy’’ because this NAS report is for the application to ‘‘building appliances’’ where DOE has statutory authority to set building appliance standards, and does not apply to determinations of energy efficiency for building energy codes. Today’s
determination is based on a review of the work of ASHRAE, as required by statute, and does not establish the efficiency standards of the ASHRAE
code.

The Building Codes Assistance Project (BCAP) submitted a written comment (Docket No. EERE–2010–BT– DET–0050–0003, pgs. 1–2) supporting the DOE’s determination and suggests that DOE follow up with the States after publication of the Final Determination as well as making public which States comply with the statutory requirements
to submit certification letters within two years of publication.

DOE does list the States that have
filed certifications and those that have or have not adopted new codes on the DOE Energy Efficiency and Renewable Energy Web site at http:// www.energycodes.gov/states/. Once a State has adopted a new commercial code, DOE typically provides software, training, and support for the new code as long as the new code is based on the national model codes (in this case, ASHRAE Standard 90.1).

The Natural Resources Defense Council (NRDC) submitted a written comment (Docket No. EERE–2010–BT– DET–0050–0006, pgs. 1–2) agreeing with and supporting the Department’s preliminary determination that
ASHRAE Standard 90.1–2010 saves energy compared to ASHRAE 90.1–2007 and urges the Department to finalize
this determination.

II. Summary of the Comparative Analysis

DOE carried out both a detailed qualitative analysis and a broad quantitative analysis of the differences between the requirements and the stringencies in the 2007 and the 2010
editions.

A. Qualitative Analysis

1. Discussion of Detailed Textual Analysis

DOE performed a detailed analysis of
the differences between the textual requirements and stringencies of the 2007 and 2010 editions in the scope of the standard, the building envelope requirements, the building lighting and power requirements, and the building mechanical equipment requirements.

The emphasis of DOE’s detailed requirement and stringency analysis was on looking at the specific changes that ASHRAE made in going from
Standard 90.1–2007 to Standard 90.1– 2010. ASHRAE publishes changes to
their standards as addenda to the preceding standard and then bundles all the addenda together to form the next edition. ASHRAE processed 109 addenda to Standard 90.1–2007 to
create Standard 90.1–2010. Each of these addenda was evaluated by DOE in preparing this final determination. No changes were made to the final detailed textual analysis from the preliminary detailed textual analysis.

In addition, each standard has multiple ways to demonstrate compliance, including a prescriptive set of requirements by section of the standard, various tradeoff approaches within those same sections, and a whole building performance method (Energy Cost Budget or ECB). For each
addendum DOE identified whether it applies to the prescriptive requirements, or one of the tradeoff paths provided for in the envelope, lighting, or mechanical sections, or the ECB whole building performance path. For each addendum DOE identified the impact on the stringency for that path to compliance.

Overall, DOE found that that the vast majority of changes made to Standard
90.1–2007 to create Standard 90.1–2010 were positive or neutral (in the context of energy efficiency). Positive changes greatly outweighed the negative energy efficiency changes. Specifically, of the 109 total changes:

56 were considered positive; 47 were considered neutral; 6 were considered negative. The 56 positive changes greatly overwhelm the 6 negative changes in terms of a simple numerical comparison. In addition, the 6 negative changes were considered to be ‘‘minor negatives’’, with 19 of the positive changes being considered ‘‘major positive’’ and an additional 37 positive changes being considered ‘‘minor positive’’. Not only do the positive changes outweigh the negative changes in raw numbers, but also in terms of the estimated impact.

2. Results of Detailed Textual Analysis

Table 1 presents the results of DOE’s addendum-by-addendum analysis of
Standard 90.1–2010. Table 6 is a reformatted and slightly modified version of a table in the preliminary qualitative analysis. The complete preliminary qualitative analysis may be

Many of these ‘‘major positive’’addenda are self descriptive. The highlevel themes of the major positive
addenda tend to be as follows:

• Better lighting, daylighting, and controls (d, i, x, ab, al, av, by, cd, cs, and dd)

• Better mechanical systems and application to more systems (e, m, n, ap, bh, bu, cb, and cy).

• Better building envelope (f). There are an additional 37 addenda that have minor positive impacts. See the complete qualitative analysis for
additional detail.

B. Quantitative Analysis

1. Discussion of Whole Building Energy Analysis

The quantitative comparison of
Standard 90.1–2010 was carried out using whole-building energy simulations of buildings built to both
Standard 90.1–2007 and Standard 90.1– 2010. DOE simulated 16 representative building types in 15 U.S. climate locations, each climate location selected to be representative of one of the 15 U.S.
climate zones used in the definition of building energy code criteria in
Standard 90.1–2007 and Standard 90.1– 2010. The simulations were developed using specific building prototypes based
on the DOE commercial reference building models developed for DOE’s Net-Zero Energy Commercial Building Initiative. (These reference building prototypes were formerly known as Benchmark building models). No changes were made to the final quantitative analysis from the preliminary quantitative analysis.

For each building prototype simulated in each climate the energy use intensities (EUI) by fuel type and by end-use were extracted. These EUIs by fuel type for each building were then weighted to national average EUI figures using weighting factors based on the relative square footage of construction represented by that prototype in each of the 15 climate regions. These weighting
factors were based on commercial building construction starts data for a five year period from 2003 to 2007. The
source of data was the McGraw-Hill Construction Projects Starts Database (MHC). The MHC database captures over 90% of new commercial construction in any given year and the collection process is independently monitored to ensure the coverage of
most of the commercial construction in the U.S. The data is used by other federal agencies such as the U.S. Census Bureau, the Federal Reserve and the U.S. Department of Health and Human Services (HHS) for characterizing building construction in the U.S. For the purpose of developing construction weighting factors, the strength of this data lies in the number of samples, the characterization of each sample in terms of building end-use and size and number of stories, the frequency of data collection, and the detailed location data. In addition, the MHC database can be used to identify multifamily residential buildings that would be
covered under ASHRAE Standard 90.1.

DOE’s prototypes reflect the use of two fuel types, electricity and natural gas. Using the weighting factors, DOE
was able to establish an estimate of the relative reduction in building energy use, as determined by a calculated reduction in weighted average site EUI for each building prototype. Site energy refers to the energy consumed at the building site. In a corresponding fashion, DOE was also able to calculate a reduction in terms of weighted average primary EUI and in terms of weighted average energy cost intensity (ECI) in $/sq. ft. of building floorspace. Primary energy as used here refers to the energy required to generate and deliver energy to the site. To estimate primary energy, all electrical energy use intensities were first converted to primary energy using a factor of 10,918 Btus primary energy per kWh (based on the 2010 estimated values reported in Table 2 of the EIA 2010 Annual Energy Outlook, release date December 2009, available at http:// www.eia.doe.gov/oiaf/archive/aeo10/ aeoref

_ tab.html). The conversion factor of 10,918 was calculated from Table 2 by summing the commercial electricity value of 4.62 quads with the electricity losses value of 10.17 quads and then dividing that sum by the commercial value. ((4.62 + 10.17)/4.62 = 3.2) This yields an electricity ratio of 3.2 for converting how much primary (source) electricity is required per unit of site required electricity. This ratio of 3.2 is then multiplied by 3,412 Btu per kWh, producing a value of 10,918 Btus primary energy per kWh of site energy. Natural Gas EUIs in the prototypes were converted to primary energy using a factor of 1.090 Btus primary energy per Btu of site natural gas use (based on the 2010 national energy use estimated shown in Table 2 of the AEO 2010). This natural gas source energy conversion factor was calculated by dividing the natural gas subtotal of 23.15 quads (sum of all natural gas usage, including usage for natural gas field production, leases, plant fuel, and pipeline (compression) supply) by the delivered natural gas total of 21.23 quads (sum of four primary energy sectors (residential, commercial, industrial, and transportation).

a. Calculation of Energy Cost Index

To estimate the reduction in energy cost index, DOE relied on national average commercial building energy prices of $0.1026/kWh of electricity and $10.06 per 1000 cubic feet ($0.9796/ therm) of natural gas, based on EIA statistics for 2009 (the last complete year of data available in Table 5B Commercial Average Monthly Bill by Census Division, and State—available
from EIA at http://www.eia.gov/cneaf/ electricity/esr/table5

_b.html and for 2009 (the last complete year of data
available from the EIA Natural Gas Annual Summary for the commercial
sector available at http:// tonto.eia.doe.gov/dnav/ng/ng

_

pri

_sum

_ dcu

_nus

_ a.htm. ) DOE recognizes that actual fuel costs will vary somewhat by building type within a region, and will in fact vary more across regions. Nevertheless, DOE believes that the use of simple national average figures illustrates whether there will be energy cost savings sufficient for the purposes
of the DOE determination.

b. Calculation of Energy Use Intensities

Energy use intensities developed for each representative building type were weighted by total national square footage of each representative building type to provide an estimate of the difference between the national energy use in buildings constructed to the 2007
and 2010 editions of the Standard 90.1. Note that the 16 buildings types used in
the final determination reflect approximately 80% of the total square footage of commercial construction including multi-family buildings greater


### 64918 Federal Register / Vol. 76, No. 202 / Wednesday, October 19, 2011 / Notices

than three stories covered under
ASHRAE Standard 90.1.

Note that only differences between new building requirements were considered in this quantitative analysis. Changes to requirements in the 2010 edition that pertain to existing buildings only are addressed in the detailed textual analysis only.

c. Application to Additions and

Renovations

Both the 2010 and 2007 editions
address additions and renovations to existing buildings. Since DOE has preliminarily found insufficient data to
characterize renovations in terms of what energy using features are utilized,
DOE has not determined that the results obtained from the whole building prototypes used would reasonably
reflect the EUI benefits that would accrue to renovated floor space. For this reason, renovated floor space is not included in the DOE weighting factors. Building additions on the other hand are believed to be substantially equivalent to new construction. For this reason, FW Dodge construction data on additions has been incorporated into the overall weighting factors. Floor space additions reflect approximately 13 percent of new construction floor space based on data captured in the FW Dodge
dataset.

d. Ventilation Rate Assumptions

The final quantitative analysis
assumed the same base ventilation level for buildings constructed to Standard
90.1–2007 and Standard 90.1–2010.
Neither edition of Standard 90.1 specifies ventilation rates for commercial building construction. ASHRAE has a separate ventilation standard for commercial construction,
ASHRAE Standard 62.1 Ventilation for Acceptable Indoor Air Quality. This standard is cited only in a few exceptions within the mechanical
sections of either Standard 90.1–2007 or Standard 90.1–2010, with each edition referencing a different version of
Standard 62.1. Standard 90.1–2007 lists
Standard 62.1–2004 in its table of
references. Standard 90.1–2010 lists
Standard 62.1–2007 in its table of
references.

Ventilation rates can have significant impact on the energy use of commercial buildings. States and local jurisdictions typically specify the ventilation requirements for buildings within their respective building codes and can set these requirements independent of the energy code requirements. Because of
the limited reference to ventilation
within either the 2007 or the 2010 edition, the requirements that States certify that their energy codes meet or
exceed the 2010 edition of Standard 90.1 would in general not require
modification of State ventilation code requirements. However, in many cases, ventilation requirements can be traced back to requirements found in one or
another version of Standard 62.1. For the purpose of the quantitative analysis,
DOE assumed ventilation rates for the simulation prototypes based on the requirements of Standard 62.1–2004.

2. Results of Whole Building Energy Analysis

The final quantitative analysis of the energy consumption of buildings built to Standard 90.1–2010, as compared with buildings built to Standard 90.1– 2007, indicates national primary energy savings of approximately 18.2 percent of commercial building energy consumption based on the weighting factors for the 16 buildings simulated. Site energy savings are estimated to be approximately 18.5 percent. Using national average fuel prices for electricity and natural gas DOE estimated a reduction in energy expenditures of 18.2 percent would
result from the use of Standard 90.1– 2010 as compared to Standard 90.1– 2007. As identified previously, these estimated savings figures do not include energy savings from equipment or appliance standards that would be in place due to Federal requirements regardless of their presence in the
Standard 90.1–2010.

Tables 3 and 4 show the aggregated energy use and associated energy savings by building type for the 16 building prototypes analyzed and on an aggregated national basis for the 2007 and 2010 editions, respectively. For each edition of Standard 90.1, the national building floor area weight used to calculate the national impact on building EUI or building ECI is presented. National-average site energy use intensities ranges from over five hundred Btu per square foot annually for the Fast Food prototype to approximately 20 Btu per square foot annually for the Non-refrigerated Warehouse type. Source energy use intensities and building energy cost intensities ($/sf-yr) are also presented.

C. Final Determination Statement

DOE’s review and evaluation indicates that there are significant
differences between the 2007 edition
and the 2010 edition. DOE’s overall
final conclusion is that the 2010 edition will improve the energy efficiency of commercial buildings.

However, DOE identified six changes in textual requirements that taken alone appear to represent a reduction in stringencies and could decrease energy efficiency. The six changes are:

• Addendum b, which allows larger
than minimum ventilation rates if required by other codes; • Addendum c, which allows an exception to dehumidification for controls for vivariums;

• Addendum p, which increases allowable pressure drop in laboratory exhaust systems;

• Addendum aw, which adds an additional lighting allowance for nightlights in hotel/motel bathrooms;

• Addendum cc, which allows higher
flow rates in 8 ′′ piping; and

• Addendum dc, which eliminates tandem wiring requirements.

DOE believes that in these cases, the reduction in stringency was not considered a major impact. For the other addenda, DOE determined that the remaining addenda either represented no change in stringency, or indicated a positive change in stringency corresponding to improved efficiency. Overall, DOE concluded the changes in textual requirements and stringencies are ‘‘positive,’’ in the sense that they would improve energy efficiency in
commercial construction.

The quantitative analysis shows that for the 16 prototype buildings, a weighted average national improvement in new building efficiency of 16.5 percent, when considering source energy, and by 17.1 percent, when considering site energy.


### 64920 Federal Register / Vol. 76, No. 202 / Wednesday, October 19, 2011 / Notices

As both the 2007 and 2010 editions cover existing buildings, to the extent that these standards are applied to existing buildings in retrofits or in new construction addition, the 2010 edition should improve the efficiency of the existing building stock.

DOE has, therefore, concluded that
Standard 90.1–2010 receive an
affirmative determination under Section 304(b) of ECPA.

III. Filing Certification Statements With

DOE

A. Review and Update

Upon publication of this affirmative final determination, each State is required to review and update, as necessary, the provisions of its commercial building energy code to meet or exceed the energy efficiency provisions of the 2010 edition. (42 U.S.C. 6833(b)(2)(B)(i)) This action is required to be taken not later than two years from the date of publication of this notice of final determination, unless an extension is provided.

The DOE recognizes that some States do not have a State commercial building energy code or have a State code that does not apply to all commercial buildings. If local building energy codes regulate commercial building design
and construction rather than a State code, the State must review and make all reasonable efforts to update as
authorized those local codes to determine whether they meet or exceed
the 2010 edition of Standard 90.1. States may base their certifications on reasonable actions by units of general purpose local government. Each such
State must still review the information obtained from the local governments and gather any additional data and testimony for its own certification.

Note that the applicability of any State revisions to new or existing buildings would be governed by the State building codes. However, it is our understanding that generally, the revisions would not apply to existing buildings unless they are undergoing a change that requires a building permit.

States should be aware that the DOE considers high-rise (greater than three stories) multi-family residential buildings, hotel, motel, and other transient residential building types of any height as commercial buildings for energy code purposes. Consequently, commercial buildings, for the purposes of certification, would include high-rise (greater than three stories) multi-family residential buildings, hotel, motel, and other transient residential building types of any height. B. Certification

Section 304(b) of ECPA, as amended, requires each State to certify to the Secretary of Energy that it has reviewed and updated the provisions of its commercial building energy code regarding energy efficiency to meet or
exceed the Standard 90.1–2010 edition. (42 U.S.C 6833(b)) Today’s final determination is being published before the 2 year deadline to file a certification for the 2007 positive determination; therefore, a state may file just one
certification to address both
determinations. The certification must
include a demonstration that the provisions of the State’s commercial building energy code regarding energy efficiency meet or exceed Standard 90.1–2010. If a State intends to certify that its commercial building energy code already meets or exceeds the requirements of Standard 90.1–2010, the State should provide an explanation of the basis for this certification, e.g., Standard 90.1–2010 is incorporated by reference in the State’s building code regulations. The chief executive of the State ( e.g., the Governor) or a designated State official, such as the Director of the State energy office, State code commission, utility commission, or equivalent State agency having primary responsibility for commercial building energy codes, is to provide the certification to the Secretary. Such a designated State official also is to provide the certifications regarding the codes of units of general purpose local government based on information provided by responsible local officials.
Certifications are to be sent to the address provided in the **ADDRESSES** section.

DOE does list the States that have
filed certifications and those that have or have not adopted new codes on the DOE Energy Efficiency and Renewable Energy Web site at http:// www.energycodes.gov/states/. Once a State has adopted a new commercial code, DOE typically provides software, training, and support for the new code as long as the new code is based on the national model codes (in this case, ASHRAE Standard 90.1).

Some States develop their own codes that are only loosely related to the
national model codes and DOE does not typically provide technical support for those codes. However, DOE does provide grants to these States through grant programs administered by the National Energy Technology Laboratory (NETL). DOE does not prescribe how each State adopts and enforces its energy codes. C. Request for Extensions To Certify
Section 304(c) of ECPA, requires that the Secretary permit an extension of the deadline for complying with the certification requirements described above, if a State can demonstrate that it has made a good faith effort to comply with such requirements and that it has made significant progress toward meeting its certification obligations. (42 U.S.C. 6833(c)) Such demonstrations
could include one or both of the following: (1) A plan for response to the requirements stated in section 304; or (2) a statement that the State has appropriated or requested funds (within State funding procedures) to implement a plan that would respond to the requirements of Section 304 of ECPA. This list is not exhaustive. Requests are to be sent to the address provided in the

**ADDRESSES** section.

IV. Regulatory Analysis

A. Review Under Executive Order 12866

Today’s action is not a significant regulatory action under section 3(f)(1) of Executive Order 12866, ‘‘Regulatory Planning and Review’’ (58 FR 51735; October 4, 1993). Accordingly, today’s action was not subject to review by the Office of Information and Regulatory Affairs (OIRA) in the Office of Management and Budget (OMB).

B. Review Under the Regulatory Flexibility Act

The Regulatory Flexibility Act (5

U.S.C. 601 et seq. ) requires the preparation of an initial regulatory flexibility analysis for any rule that by law must be proposed for public comment, unless the agency certifies that the rule, if promulgated, will not have a significant economic impact on
a substantial number of small entities. As required by Executive Order 13272, ‘‘Proper Consideration of Small Entities in Agency Rulemaking,’’ (67 FR 53461 (Aug. 16, 2002)), DOE published procedures and policies on February 19, 2003, to ensure that the potential impacts of its rules on small entities are properly considered during the rulemaking process (68 FR 7990). DOE has made its procedures and policies
available on the Office of General
Counsel’s Web site: http:// www.gc.doe.gov.

DOE has reviewed today’s final determination under the provisions of the Regulatory Flexibility Act and the procedures and policies published on February 19, 2003. Since today’s action on the determination of improved energy efficiency between the 2007 and
2010 editions of Standard 90.1 is now finalized by DOE, it requires States to


### 64921 Federal Register / Vol. 76, No. 202 / Wednesday, October 19, 2011 / Notices

undertake an analysis of their respective building codes. As such, the only entities directly regulated by this final
determination would be States. DOE does not believe that there will be any direct impacts on small entities such as small businesses, small organizations, or small governmental jurisdictions.

On the basis of the foregoing, DOE
certifies that this final determination would not have a significant economic impact on a substantial number of small entities. Accordingly, DOE has not prepared a regulatory flexibility analysis
for this final determination. DOE’s certification and supporting statement of factual basis will be provided to the Chief Counsel for Advocacy of the Small Business Administration pursuant to 5 U.S.C. 605(b).

C. Review Under the National Environmental Policy Act of 1969

Today’s action is covered under the Categorical Exclusion found in DOE’s National Environmental Policy Act regulations at paragraph A.6. of Appendix A to subpart D, 10 CFR part 1021. That Categorical Exclusion applies to actions that are strictly procedural, such as rulemaking establishing the administration of grants. Today’s action is required by Title III of ECPA, as amended, which provides that whenever the Standard 90.1–1989, or any successor to that code, is revised, the Secretary must make a determination, not later than 12 months after such revision, whether the revised code would improve energy efficiency in commercial buildings and must publish notice of such
determination in the Federal Register

. (42 U.S.C. 6833(b)(2)(A)) If the Secretary
determines that the revision of Standard 90.1–1989 or any successor thereof, improves the level of energy efficiency in commercial buildings then no later than two years after the date of the publication of such affirmative determination, each State is required to certify that it has reviewed and updated the provisions of its commercial building code regarding energy efficiency with respect to the revised or successor code. (42 U.S.C. 6833(b)(2)(B)(i)) If the Secretary makes a
determination that the revised standard will not improve energy efficiency in commercial buildings then State
commercial codes shall meet or exceed
the last revised standard for which the Secretary has made a positive determination. (42 U.S.C. 6833(b)(2)(B)(ii)) Therefore, DOE has preliminarily determined that the Secretary’s determination is not a major
federal action that would have direct environmental impacts. Accordingly, DOE has not prepared an environmental assessment or an environmental impact

statement.

D. Review Under Executive Order 13132, ‘‘Federalism’’

Executive Order 13132, 64 FR 43255 (Aug 4, 1999), imposes certain requirements on agencies formulating and implementing policies or regulations that pre-empt State law or that have federalism implications. Agencies are required to examine the constitutional and statutory authority supporting any action that would limit the policymaking discretion of the States and carefully assess the necessity
for such actions.

DOE has reviewed the statutory authority. Congress found that:

(1) Large amounts of fuel and energy are consumed unnecessarily each year in heating, cooling, ventilating, and providing domestic hot water for newly
constructed residential and commercial buildings because such buildings lack adequate energy conservation features;

(2) Federal voluntary performance standards for newly constructed buildings can prevent such waste of energy, which the Nation can no longer
afford in view of its current and anticipated energy shortage;

(3) the failure to provide adequate energy conservation measures in newlyconstructed buildings increases longterm operating costs that may affect adversely the repayment of, and security for, loans made, insured, or guaranteed by Federal agencies or made by federally insured or regulated instrumentalities; and

(4) State and local building codes or similar controls can provide an existing means by which to assure, in coordination with other building requirements and with a minimum of
Federal interference in State and local transactions, that newly constructed buildings contain adequate energy conservation features. (42 U.S.C. 6831)

Pursuant to Section 304(b) of ECPA, DOE is statutorily required to determine
whether the most recent versions of ASHRAE 90.1 would improve the level of energy efficiency in commercial buildings as compared to the previous version. If DOE makes a positive determination, the statute requires each State to certify that it has reviewed and updated the provisions of its commercial building code regarding energy efficiency with respect to the revised or successor codes. (42 U.S.C. 6833(b)(2)(B)(i))

Executive Order 13132, 64 FR 43255 (August 4, 1999) requires meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications unless ‘‘funds necessary to pay the direct costs incurred by the State and local governments in complying with the regulation are provided by the Federal Government.’’ (62 FR 43257) Pursuant to section 304(e) of ECPA, the DOE Secretary is required to ‘‘provide incentive funding to States to implement the requirements of [Section 304], and to improve and implement State residential and commercial building energy efficiency codes, including increasing and verifying compliance with such codes. In determining whether, and in what amount, to provide incentive funding under this subsection, the Secretary shall consider the actions proposed by the State to implement the requirements of this section, to improve and implement residential and commercial building energy efficiency codes, and to promote building energy efficiency through the use of such codes.’’ (42 U.S.C. 6833(e)) Therefore, consultation with States and local officials regarding
this final determination was not required.

However, DOE notes that State and local governments were invited to participate in the development Standard 90.1–2010. Standard 90.1–2010, was developed in a national ANSI consensus process open to the public and in which State and local governments participate along with DOE and other interested parties. It is the product of a series of amendments to the prior addition of the standard. Each addendum is put out for national public review. Anyone may submit comments, and in the process
comments were received from State and local governments. Comments on the addendum are received, reviewed and resolved through a consensus process. Members of the standards project
committee have included representatives of State and local governments.

DOE annually holds a national building energy codes workshop at which the progress on development of the model energy codes are presented, along with discussion and sharing of problems and successes in adoption, implementation, and enforcement of building energy codes. The predominate attendance of these workshops are State and local officials responsible for building energy codes. They are consistently encouraged and urged to participate in the model building energy code processes, which will be the subject of DOE’s next determinations under section 304 of ECPA. Thus, State
and local officials have had the opportunity to participate in the development of the standard through

the ASHRAE process. Some have done

so.

Similarly, the comments of States and local governments about provisions of the developing Standard 90.1–2010
were received in formal comment periods and heard and addressed in ASHRAE committee deliberations open to the public. In addition, concerns and issues about adoption, implementation and enforcement issues were presented
and discussed at informal sessions at the Department’s annual national workshops on building energy codes. DOE believes that the above process has given State and local jurisdictions extensive opportunity to comment on and express their concerns on Standard 90.1–2010, the subject of this
determination.

On issuance of a final determination that Standard 90.1–2010 would improve the energy efficiency of commercial buildings, ECPA requires the States to certify to the Secretary that it has reviewed and updated the provisions of its commercial building code regarding energy efficiency to meet or exceed the requirements of Standard 90.1–2010.
DOE notes that ECPA sets forth this requirement for States. (42 U.S.C. 6833(b)(2)(B)(i)) States are given broad freedom to either adopt Standard 90.1– 2010 or develop their own code that meets equivalent energy efficiency.

E. Review Under the Unfunded Mandates Reform Act of 1995

The Unfunded Mandates Reform Act of 1995 (Pub. L. 104–4) generally requires Federal agencies to examine closely the impacts of regulatory actions on State, local, and tribal governments. Subsection 101(5) of Title I of that law defines a Federal intergovernmental mandate to include any regulation that would impose upon State, local, or tribal governments an enforceable duty, except a condition of Federal assistance or a duty arising from participating in a voluntary Federal program. Title II of that law requires each Federal agency to assess the effects of Federal regulatory actions on State, local, and tribal governments, in the aggregate, or to the private sector, other than to the extent such actions merely incorporate requirements specifically set forth in a statute. Section 202 of that title requires a Federal agency to perform a detailed assessment of the anticipated costs and benefits of any rule that includes a Federal mandate which may result in costs to State, local, or tribal governments, or to the private sector, of $100 million or more. Section 204 of that title requires each agency that proposes a rule containing a significant Federal intergovernmental mandate to develop an effective process for obtaining meaningful and timely input from elected officers of State, local, and tribal governments.

Upon publication of this affirmative final determination, each State is required under section 304 of ECPA to review and update, as necessary, the provisions of its commercial building energy code to meet or exceed the provisions of the 2010 edition of Standard 90.1. (42 U.S.C. 6833(b)(2)(B)(i)) Section 304 of ECPA requires State action in response to this positive determination by DOE. The statutory requirements of ECPA require DOE to provide a determination irrespective of costs. While the processes that States may undertake to update their codes vary widely, as a general rule a State at a minimum needs

to:

• Evaluate Standard 90.1–2010 using the background material provided by

DOE

• Compare the existing State commercial building energy code to Standard 90.1–2010 to see if an update
is needed

• Update the State commercial building energy code to meet or exceed
Standard 90.1–2010.

DOE evaluated the potential for State activity to exceed $100 million in any one year. The approach looked at the three steps for minimum activity listed in the previous paragraph—evaluate, compare and update. A fourth potential step of providing training on the new
code was also considered as some States may consider training on the new code to be an integral part of adopting the new code. For the three steps of minimum activity, DOE estimated the following:

Evaluate Standard 90.1–2010—DOE
estimated a minimum of 8 hours of review per State and a maximum review time of 500 hours of review per State (12.5 work weeks). The minimum review time of 8 hours (one day) is the
estimated minimum amount of time DOE can see States taking to review Standard 90.1–2010. Reading and reviewing the Federal Register notice, the qualitative analysis document and the quantitative analysis document will take the average person several hours. Deciding on whether or not to upgrade to Standard 90.1–2010 may take another couple of hours. The maximum review time of 500 hours (62.5 day, 3 working months) upper limit was estimated as
the amount of time that a State that was not familiar with energy codes at all or which has a particularly arduous review process within the State would take to
review these documents. (1) A cost per hour of $100 per hour
was assumed based on actual rates proposed in subcontracts associated with compliance studies funded by DOE. The average rate calculated from these subcontracts for 10 types of building officials from 6 states was $93.41, so DOE chose to round this up to $100 per hour.

a. Low estimate—8 hours × 50 states × $100 per hour = $40,000. b. High estimate—500 hours × 50 states

× $100 per hour = $2,500,000. (2) Compare Standard 90.1–2010 to existing state code—Assuming the State
is familiar with its code and has performed an effective evaluation of Standard 90.1 in the first step, the range of potential costs should be similar to Step 1. (See Step 1 for discussion of 8 hour and 500 hour times and $100 per hour cost estimate).

a. Low estimate—8 hours × 50 states × $100 per hour = $40,000. b. High estimate—500 hours × 50 states

× $100 per hour = $2,500,000. (3) Update the State Codes to meet or exceed Standard 90.1–2010—Adopting a new energy code could be as simple as updating an order within the State, or it could be very complex involving hearings, testimony, etc. Again, the range of potential costs should be similar to Step 1. (See Step 1 for discussion of origin of 8 hour and 500 hour times and $100 per hour cost estimate).

a. Low estimate—8 hours × 50 states × $100 per hour = $40,000. b. High estimate—500 hours × 50 states

× $100 per hour = $2,500,000. The potential range of total costs States to under these assumptions would be $120,000 to $7.5 million. This range is well below the $100 million
threshold in the Unfunded Mandates Act. DOE has also considered potential costs were States to provide training on
the new code.

(4) Train Code officials on New Code—Assuming every jurisdiction has at least one person that needs to be trained on energy code. There are roughly 40,000 general purpose local governments, or jurisdictions, in the U.S.. The total number of jurisdictions in the U.S. that enforce energy codes is not known with any degree of certainty. The National League of Cities publishes
an estimate of the number of local governments in the U.S. at http:// www.nlc.org/build-skills-networks/resources/cities-101/number-of-localgovernments—population-distribution. Their summary indicates the following:

• 19,492 Municipal governments;

• 16,519 Town or Township governments;


### 64923 Federal Register / Vol. 76, No. 202 / Wednesday, October 19, 2011 / Notices

• 3,033 County governments;

• 13,726 School districts; and

• 37,381 Special district governments.

(5) DOE believes it is reasonable to assume that all of the municipal governments, town or township governments, and county governments could be required to acquire training on
Standard 90.1–2010 in order to enforce this standard as an adopted energy code. In addition, the 50 state governments would be required to acquire training. This number adds up to
19,429+16,504+3,033+50 = 39,094. Another widely mentioned estimate of the total number of code adopting jurisdictions in the U.S. is 44,000. This
number is based on the National Conference of States on Building Codes and Standards (NCBCS). See, for example, http://www.ncsbcs.org/ newsite/New%20Releases/

RW

_Presentation

_ 060602.htm. Both
these estimates are in reasonable agreement and so DOE assumed that there are 40,000 potential jurisdictions that potentially would need training on a new energy code.

Based on training experiences of the Building Energy Codes Program staff, with conducting training sessions for jurisdictional staff regarding Standard 90.1, one full-day (8 hours) of training is normally sufficient. Therefore, DOE
has used 8 hours as a low estimate and 16 hours as a high estimate for training hours required if a jurisdiction were to adopt Standard 90.1–2010.

a. Low estimate—8 hours × 40,000 jurisdictions × $100 per hour = $32,000,000. b. High Estimate—16 hours × 40,000 jurisdictions × $100 per hour = $64,000,000.
Adding the potential training costs of $32 million to $64 million to the costs for the three steps indicates a potential total costs ranging from $32.12 million to $71.5 million. The high end of this estimate is less than the $100 million
threshold in the Unfunded Mandates Act. Accordingly, no further action is required under the Unfunded Mandates
Reform Act of 1995.

F. Review Under the Treasury and General Government Appropriations Act of 1999

Section 654 of the Treasury and General Government Appropriations Act of 1999 (Pub. L. 105–277) requires Federal agencies to issue a Family Policymaking Assessment for any rule that may affect family well-being. Today’s action would not have any impact on the autonomy or integrity of the family as an institution. Accordingly, DOE has concluded that it is not necessary to prepare a Family Policymaking Assessment.

G. Review Under the Treasury and General Government Appropriations Act of 2001

Section 515 of the Treasury and General Government Appropriations Act, 2001 (44 U.S.C. 3516, note) provides for agencies to review most
disseminations of information to the public under guidelines established by each agency pursuant to general guidelines issued by OMB. OMB’s guidelines were published at 67 FR 8452 (Feb. 22, 2002), and DOE’s guidelines were published at 67 FR 62446 (Oct. 7, 2002). DOE has reviewed today’s action under the OMB and DOE guidelines and has concluded that it is consistent with applicable policies in those guidelines.

H. Review Under Executive Order 13211

Executive Order 13211, ‘‘Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use,’’ 66 FR 28355 (May 22, 2001), requires Federal agencies to prepare and submit to the OMB a Statement of Energy Effects for any proposed significant energy action. A ‘‘significant energy action’’ is defined as any action by an agency that promulgated or is expected to lead to promulgation of a final rule, and that: (1) Is a significant regulatory action under Executive Order 12866, or any successor order; and (2) Is likely to have a significant adverse effect on the supply, distribution, or use of energy; or (3) Is designated by the Administrator of the Office of Information and Regulatory Affairs (OIRA) as a significant energy action. For any proposed significant energy action, the agency must give a detailed statement of any adverse effects on energy supply, distribution, or use, should the proposal be implemented,
and of reasonable alternatives to the action and their expected benefits on energy supply, distribution, and use.

Today’s action would not have a significant adverse effect on the supply, distribution, or use of energy and is therefore not a significant energy action. Accordingly, DOE has not prepared a Statement of Energy Effects.

I. Review Under Executive Order 13175

Executive Order 13175. ‘‘Consultation
and Coordination with Indian tribal Governments’’ (65 FR 67249 (Nov. 9, 2000)), requires DOE to develop an accountable process to ensure ‘‘meaningful and timely input by tribal officials in the development of regulatory policies that have tribal implications.’’ ‘‘Policies that have tribal implications’’ refers to regulations that
have ‘‘substantial direct effects on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal
Government and Indian tribes.’’

Today’s action is not a policy that has ‘‘tribal implications’’ under Executive Order 13175. DOE has reviewed today’s
action under Executive Order 13175 and
has determined that it is consistent with applicable policies of that Executive
Order.

Issued in Washington, DC, on October 12,

2011. Henry Kelly, Acting Assistant Secretary, Energy Efficiency and Renewable Energy.
