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. mstockstill on DSK4VPTVN1PROD with NOTICES 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) provides for agencies to review most disseminations of information to the public under guidelines established by each agency pursuant to general guidelines issued by the Office of Management and Budget (OMB). Both OMB and DOE have published established relevant guidelines (67 FR 8452 and 67 FR 62446, respectively). 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. Review Under Executive Order 13211 Executive Order 13211, ‘‘Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use,’’ (66 FR 28355), 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 OMB 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. Review Under Executive Order 13175 Executive Order 13175, ‘‘Consultation and Coordination with Indian tribal Governments’’ (65 FR 67249), 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 September 18, 2014.

ACTION: Notice of Preliminary Determination. AGENCY: The U.S. Department of Energy (DOE) has preliminarily determined that the 2015 edition of the International Energy Conservation Code (IECC) would improve energy efficiency in buildings subject to the code compared to the 2012 edition. DOE analysis indicates that buildings meeting the 2015 IECC (as compared with buildings meeting the 2012 IECC) would result in national source energy savings of approximately 1.03 percent, site energy savings of approximately 1.12 percent, and energy cost savings of approximately 0.90 percent of residential building energy consumption, as regulated by the IECC. If this determination is finalized, each State would be required by statute to certify that it has reviewed the provisions of its residential building code regarding energy efficiency, and made a determination as to whether to update their code to meet or exceed the 2015 IECC. Additionally, this notice provides guidance to States on these processes and associated certifications. DATES: Comments must be provided by October 27, 2014.

Statutory Authority Title III of the Energy Conservation and Production Act (ECPA), as amended, establishes requirements for building energy conservation standards, administered by the DOE Building Energy Codes Program. (42 U.S.C. 6831 et seq.) Section 304(a), as amended, of ECPA provides that whenever the 1992 Model Energy Code (MEC), or any successor to that code, is revised, the Secretary of Energy (Secretary) must make a determination, not later than 12 months after such revision, whether the revised code would improve energy efficiency in residential buildings, and must publish notice of such determination in the Federal Register. (42 U.S.C. 6833(a)(5)(A)) The Secretary may determine that the revision of the 1992 MEC, or any successor thereof, improves the level of energy efficiency in residential buildings. If so, then not later than 2 years after the date of the publication of such affirmative determination, each State is required to certify that it has reviewed its residential building code regarding energy efficiency, and made a determination as to whether it is appropriate to revise its code to meet or exceed the provisions of the successor code. (42 U.S.C. 6833(a)(5)(B)) State determinations are to be made: (1) After public notice and hearing; (2) in writing; (3) based upon findings included in such determination and upon evidence presented at the hearing; and (4) available to the public. (See 42 U.S.C. 6833(a)(2)) In addition, if a State determines that it is not appropriate to revise its residential building code, the State is required to submit to the Secretary, in writing, the reasons, which are to be made available to the public. (See 42 U.S.C. 6833(a)(4)) ECPA 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(a) of ECPA, and that it has made significant progress in doing so. (42 U.S.C. 6833(c)) DOE is also directed to provide technical assistance to States to support implementation of State residential and commercial building energy efficiency codes. (42 U.S.C. 6833(d)) B. Background The International Energy Conservation Code (IECC) is the national model code establishing energy efficiency requirements for residential buildings. The IECC is revised every 3 years through a code development and PO 00000 Frm 00048 Fmt 4703 Sfmt 4703 consensus process administered by the International Code Council (ICC).1 Code change proposals may be submitted by any interested party, and are evaluated through a series of public hearings. As part of the ICC process, any interested party may submit proposals, as well as written comments or suggested changes to any proposal, and make arguments before a committee of experts assembled by the ICC. At the final public hearing, arguments are presented to and voted upon by the ICC Governmental Member Representatives, with the collection of accepted proposals forming the revised edition of the IECC. The ICC published the 2015 edition of the IECC (2015 IECC or 2015 edition) on June 3, 2014, which forms the basis of this determination notice. II. Methodology In arriving at a preliminary determination, DOE reviewed all changes between the 2015 and 2012 editions of the IECC. The IECC covers a broad spectrum of the energy-related components and systems in buildings, ranging from simpler residential buildings to more complex multifamily facilities. For the purposes of its preliminary determination, DOE focused only on low-rise residential buildings, defined in a manner consistent with the ICC and the American Society of Heating, Refrigerating and Air-conditioning Engineers (ASHRAE). Low-rise residential buildings include one- and two-family detached and attached buildings, and low-rise multifamily buildings (not greater than three stories), such as condominiums and garden apartments. The 2015 IECC was developed through the same approach as the previous 2012 edition with approval through the ICC consensus process. The 2015 edition contains no significant changes to the overall scope or the structure of the prescriptive and mandatory provisions of the code, which form the basis of the DOE determination analysis. As a result, DOE preliminarily determined that the methodology used for the analysis of the 2012 IECC should again be utilized for the analysis of the 2015 IECC. Overview of Methodology The analysis methodology used by DOE contains both qualitative and quantitative components. A qualitative comparison is undertaken to identify textual changes between requirements in the 2015 and 2012 editions of the 1 More information on the ICC code development and consensus process is described at https://www. iccsafe.org/cs/codes/Pages/procedures.aspx E:\FR\FM\26SEN1.SGM 26SEN1 Federal Register / Vol. 79, No. 187 / Friday, September 26, 2014 / Notices IECC, followed by a quantitative assessment of energy savings conducted through whole-building simulations of buildings constructed to meet the minimum requirements of each code over a range of U.S. climates. The analysis methodology, which was previously developed through a public comment process, is available on the DOE Building Energy Codes Program Web site.2 Consistent with its previous determinations, DOE compared overall editions of the IECC, and did not issue determinations for individual code changes. DOE interprets the language in section 304(a) of ECPA to mean that when a comprehensive revision of the 1992 MEC is published (which in this case is the 2015 IECC), then that revised or successor code triggers the Secretary’s obligation to issue a determination as to whether the revised code improves energy efficiency in residential buildings. (See 42 U.S.C. 6833(a)(5)(A)) This determination is made by comparing the revised or successor code to the last predecessor code. Consideration for Technological and Economic Factors Section 304(a) of ECPA states that the Secretary is required to make a determination as to whether any successor standard to the 1992 MEC will improve energy efficiency. (42 U.S.C. 6833(a)(5)(A)) Section 304 of ECPA does not include any reference to economic justification, although such criteria are considered directly by the ICC code development and consensus process, as applicable. Each proposal submitted to the ICC code development process also requires a declaration of whether the proposed code change will increase the cost of construction. Separate from the Secretary’s determination under section 304(a), section 307 of ECPA requires DOE to periodically review the technical and economic basis of the voluntary building energy codes, and participate in the industry process for review and modification, including seeking adoption of all technologically feasible and economically justified energy efficiency measures. (42 U.S.C. 6836(b)) In fulfillment of this directive, DOE evaluates its code change proposals submitted to the ICC, analyzing energy savings and cost-effectiveness, as applicable, and otherwise participates in the ICC process. In addition, DOE performs independent technical and economic analysis of the IECC as part of its direction to provide assistance to States implementing building energy codes. This approach allows DOE to meet its statutory obligation to participate in the industry process for review and modification of the IECC, and to seek adoption of all technologically feasible and economically justified energy efficiency measures. (42 U.S.C. 6836(b)) In preparation for technical assistance activities, DOE previously developed a standardized methodology for assessing the cost-effectiveness of code changes through a public process. (78 FR 47677) This methodology is published on the DOE Building Energy Codes Program Web site, and has been applied by DOE in the development of code change proposals for the IECC, as well as assessing the cost-effectiveness of published editions of the IECC. DOE expects to update this methodology periodically to ensure its assumptions and economic criteria remain valid and adequate for States considering adoption of model building energy codes. III. Summary of Findings In performing its determination, DOE performed both a qualitative and quantitative analysis of the prescriptive and mandatory requirements contained 57917 in the 2015 IECC. The chosen methodology for these analyses is consistent with actions of recent determinations, and provides a reasonable assessment of how the code will affect energy savings in residential buildings. A summary of the analyses supporting DOE’s determination is outlined in the following sections. Qualitative Analysis DOE performed a comparative analysis of the textual requirements of the 2015 IECC, examining the specific changes (approved code changes) made between the 2012 and the 2015 editions. The ICC Code Hearing process considers individual code changes for approval, and then bundles all the approved code changes together to form the next published edition. In creating the 2015 IECC, ICC processed 77 approved code change proposals. DOE evaluated each of these code change proposals in preparing its determination. Overall, DOE found that the vast majority of changes in the 2015 IECC appear to be neutral (i.e., have no direct impact on energy savings) within the context of the determination analysis. DOE also found that beneficial changes (i.e., increased energy savings) outweigh any changes with a detrimental effect on energy efficiency in residential buildings. Of the 77 total changes: • 6 were considered beneficial; • 62 were considered neutral; • 5 were considered negligible; • 3 were considered detrimental; and • 1 was considered to have an unquantifiable impact. Table III.1 presents the findings resulting from the qualitative analysis, along with a description of the change, as well as an assessment of the anticipated impact on energy savings in residential buildings.

While this change does not directly alter stringency of the code, it does provide an additional compliance path as an alternative to the IECC prescriptive and performance paths. DOE determination analyses have historically been based on the prescriptive compliance path. This has been done because: (1) The prescriptive compliance path is generally considered the predominant compliance path, and; (2) the performance path effectively allows a limitless number of ways to comply with the code, and no accepted methodology exists for how to analyze it. Equally important, there is no aggregated source of data allowing for documentation of how buildings meet the performance path criteria. In the absence of such data, an analysis of the performance path would have no empirical basis. The inclusion of a new type of compliance path in the 2015 IECC, which is based on an Energy Rating Index (ERI), prompted DOE to review its historical approach of using only the prescriptive path, and make a decision as to whether a change in methodology would be appropriate for the current determination analysis. Three primary points were considered: (1) The impact of the ERI path on national residential energy consumption is dependent on the number of homes that use this new path, and the unique building characteristics of those homes. As no jurisdiction has yet implemented the 2015 IECC, there is no way to know how many homes will use this path. (2) An analysis conducted by Pacific Northwest National Laboratory (PNNL) concluded that most homes built using the ERI path, as specified in the 2015 IECC, are likely to be at least as efficient as the homes built to meet the prescriptive requirements of the IECC or the traditional performance path.4 (3) Including the new ERI path but not the traditional performance path would be arbitrary relative to historical determination analysis. An accepted methodology, along with a supporting data source, by which to analyze the performance path would also be necessary, and is not currently available. Based on these three points, DOE concluded that it is appropriate to follow its historical approach for the current determination. However, DOE acknowledges that the landscape of code compliance may be changing, and therefore plans to track the implementation and application of the new ERI path, as well as collect relevant data that may enable DOE to further evaluate the ERI path in future analyses. DOE will also investigate the possibility of collecting data that could provide the basis for a broader analysis of performance-based compliance paths. Finally, DOE will explore whether the total number of homes built under each path can be determined and tracked over time. DOE anticipates that multiple paths may be considered in future determinations, but will only be included if the potential energy savings are large enough to significantly change the results that would occur from an analysis of prescriptive requirements. Table III.2 summarizes the overall impact of the code change proposals in the qualitative analysis. Overall, the sum of the beneficial code changes (6) is greater than the number of the detrimental code change proposals (3). 4 Taylor et al., Identification of RESNET HERS Index Values Corresponding to Minimal Compliance with the IECC (PNNL, Richland, WA, May 2014), available at https://www.energycodes. gov/hers-and-iecc-performance-path VerDate Sep<11>2014 19:14 Sep 25, 2014 Jkt 232001 PO 00000 Frm 00055 Fmt 4703 Sfmt 4703 E:\FR\FM\26SEN1.SGM 26SEN1 57924 Federal Register / Vol. 79, No. 187 / Friday, September 26, 2014 / Notices TABLE III.2—OVERALL SUMMARY OF CODE CHANGE PROPOSAL IMPACT IN QUALITATIVE ANALYSIS Detriment Neutral Benefit Negligible impact Unquantifiable at this time Total 3 62 6 5 1 77 Quantitative Analysis The quantitative analysis of the 2015 IECC was carried out using wholebuilding energy simulations of prototype buildings designed to meet the requirements of the 2012 IECC and the 2015 IECC. DOE simulated 32 representative residential building types across 15 U.S. climate locations, with locations selected to be representative of all U.S climate zones, as defined by the IECC. Energy use intensities (EUI) by fuel type and by end-use, as regulated by the IECC (i.e., heating, cooling, domestic water heating and lighting) were extracted for each building type, and weighted by the relative square footage of construction (represented by building type in each climate regions). The quantitative analysis of buildings designed to meet the requirements of the 2015 IECC indicates national site energy savings of 1.12 percent of residential building energy consumption, as regulated by the IECC (in comparison to the 2012 IECC). Associated source energy savings are estimated to be approximately 1.03 percent, and national average energy cost savings are estimated to be approximately 0.90 percent. Table III.3 and Table III.4 show the energy use and associated savings resulting from the 2015 IECC by climate zone and on an aggregated national basis. Further details on the quantitative analysis can be found in the technical support document.

Preliminary Determination Statement Review and evaluation of the 2012 and 2015 editions of the IECC indicate that there are differences between the two editions. Qualitative analysis of the updated code reveals that many of the code changes are anticipated to have a neutral impact on energy efficiency, while a small number of code changes are anticipated to yield improved energy efficiency, and a smaller number of code changes are anticipated to be detrimental to energy efficiency. In addition, quantitative analysis of the code indicates regulated site energy, source energy, and energy cost savings of 1.12 percent, 1.03 percent and 0.90 percent, respectively. DOE has rendered the preliminary conclusion that the 2015 IECC will improve energy efficiency in residential buildings, and, therefore, should receive an affirmative determination under Section 304(a) of ECPA. V. State Certification If today’s determination is finalized, each State would be required to determine the appropriateness of revising the portion of its residential building code regarding energy efficiency to meet or exceed the energy efficiency provisions of the 2015 IECC. (42 U.S.C. 6833(a)(5)(B)) This action must be made not later than 2 years from the date of publication of a Notice of Final Determination, unless an extension is provided. mstockstill on DSK4VPTVN1PROD with NOTICES State Review and Update The State determination must be: (1) Made after public notice and hearing; (2) in writing; (3) based upon findings and upon the evidence presented at the hearing; and (4) made available to the public. (42 U.S.C. 6833(a)(2)) States have discretion with regard to the hearing procedures they use, subject to providing an adequate opportunity for members of the public to be heard and to present relevant information. The Department recommends publication of any notice of public hearing through appropriate and prominent media outlets, such as in a newspaper of general circulation. States should also be aware that this determination does not apply to IECC chapters specific to nonresidential buildings, as defined in VerDate Sep<11>2014 19:14 Sep 25, 2014 Jkt 232001 the IECC. Therefore, if today’s action is finalized, States must certify their evaluations of their State building codes for residential buildings with respect to all provisions of the IECC, except for those chapters not affecting residential buildings. State Certification Statements If a State makes a determination that it is not appropriate to revise the energy efficiency provisions of its residential building code, the State must submit to the Secretary, in writing, the reasons for this determination and the statement shall be available to the public. (42 U.S.C. 6833(a)(4)) State certifications are to be sent to the address provided in the ADDRESSES section, or may be submitted to BuildingEnergyCodes@ee.doe.gov. The DOE Building Energy Codes Program tracks and reports State code adoption and certifications.5 Once a State has adopted an updated residential code, DOE typically provides software, training, and support for the new code, as long as the new code is based on the national model code (i.e., the 2015 IECC). DOE has issued previous guidance on how it intends to respond to technical assistance requests related to implementation resources, such as building energy code compliance software. (79 FR 15112) DOE also recognizes that 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 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. (See 42 U.S.C. 6833(e)) DOE does not prescribe how each State adopts and enforces its energy codes. Requests for Extensions 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 5 Available at https://www.energycodes.gov/ adoption/states PO 00000 Frm 00057 Fmt 4703 Sfmt 4703 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, or may be submitted to BuildingEnergyCodes@ee.doe.gov. VI. Regulatory Review and Analysis Review Under Executive Orders 12866 and 13563 Today’s action is not a significant regulatory action under Section 3(f) of Executive Order 12866, ‘‘Regulatory Planning and Review’’ (58 FR 51735). Accordingly, today’s action was not reviewed by the Office of Information and Regulatory Affairs (OIRA) in the Office of Management and Budget (OMB). DOE has also reviewed this regulation pursuant to Executive Order 13563, issued on January 18, 2011. (76 FR 3281) Executive Order 13563 is supplemental to and explicitly reaffirms the principles, structures, and definitions governing regulatory review established in Executive Order 12866. 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), 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 also made its procedures and E:\FR\FM\26SEN1.SGM 26SEN1 57926 Federal Register / Vol. 79, No. 187 / Friday, September 26, 2014 / Notices mstockstill on DSK4VPTVN1PROD with NOTICES policies available on the Office of General Counsel Web site.6 DOE has reviewed today’s action under the provisions of the Regulatory Flexibility Act and the procedures and policies published in February 2003. Once DOE finalizes this determination of improved energy efficiency, it would require States to undertake an analysis of their respective building codes. As such, the only entities directly regulated by this 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. Based on the foregoing, DOE certifies that this preliminary 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 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). 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 1992 MEC, 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 residential buildings and must publish notice of such determination in the Federal Register. (42 U.S.C. 6833(a)(5)(A)) If the Secretary determines that the revision of 1992 MEC, or any successor thereof, improves the level of energy efficiency in residential buildings, then no later than 2 years after the date of the publication of such affirmative determination, each State is required to certify that it has reviewed its residential building code regarding energy efficiency and made a determination whether it is appropriate to revise its code to meet or exceed the provisions of the successor code. (42 U.S.C. 6833(a)(5)(B)) Therefore, DOE has 6 Available at https://energy.gov/gc/office-generalcounsel VerDate Sep<11>2014 19:14 Sep 25, 2014 Jkt 232001 determined that this preliminary 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. Review Under Executive Order 13132, ‘‘Federalism’’ Executive Order 13132 (64 FR 43255) 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. 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 newly constructed 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 ensure, 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(a) of ECPA, DOE is statutorily required to determine whether the most recent edition of the MEC (or its successor) would improve the level of energy efficiency in residential buildings as compared to the previous edition. If DOE makes a positive determination, the statute requires each State to certify that it has reviewed its residential building code regarding energy efficiency and made a determination whether it is appropriate to revise its code to meet or exceed the provisions of the successor code. (42 U.S.C. 6833(a)(5)(B)) PO 00000 Frm 00058 Fmt 4703 Sfmt 4703 Executive Order 13132 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 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, the Secretary must 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. (See 42 U.S.C. 6833(e)) Therefore, consultation with States and local officials regarding this determination was not required. However, DOE notes that State and local governments were invited to participate in the development of the 2015 IECC. The IECC is developed in a national consensus process open to the public, and in which State and local governments may participate, along with the general public. The updated code is the product of a series of code change proposals to the prior edition of the code, with each change made available for public review, and with any interested party having the ability to participate and submit comments. Comments on the code change proposals and public comments are received, reviewed, and resolved through an established process administered by the ICC. Many representatives from State and local governments participate in the code development hearings. As directed by Congress, DOE believes that this process has given State and local jurisdictions extensive opportunity to comment and express any concerns on the 2015 IECC, the subject of this determination. Within two years from the issuance of a final determination that the 2015 IECC would improve the energy efficiency of residential buildings, ECPA requires each State to certify to the Secretary that it has reviewed its residential building code regarding energy efficiency, and made a determination whether it is appropriate to revise its code to meet or exceed the provisions of the successor code. DOE notes that ECPA sets forth E:\FR\FM\26SEN1.SGM 26SEN1 Federal Register / Vol. 79, No. 187 / Friday, September 26, 2014 / Notices Review Under the Treasury and General Government Appropriations Act of 2001 this requirement for States. (42 U.S.C. 6833(a)(5)(B)) States are given broad freedom to either adopt the IECC or develop their own code that meets or exceeds the IECC. Review Under 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 an assessment of the anticipated costs and benefits of any rule that includes a Federal mandate that 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. Consistent with previous determinations, DOE has completed its review, and concluded that impacts on state, local, and tribal governments are less than the $100 million threshold specified in the Unfunded Mandates Act. Accordingly, no further action is required under the Unfunded Mandates Reform Act of 1995. mstockstill on DSK4VPTVN1PROD with NOTICES 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. VerDate Sep<11>2014 19:14 Sep 25, 2014 Jkt 232001 Section 515 of the Treasury and General Government Appropriations Act, 2001 (44 U.S.C. 3516) 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. Both OMB and DOE have published established relevant guidelines (67 FR 8452 and 67 FR 62446, respectively). 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. Review Under Executive Order 13211 Executive Order 13211, ‘‘Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use,’’ (66 FR 28355), 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 OMB 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. Review Under Executive Order 13175 Executive Order 13175, ‘‘Consultation and Coordination with Indian tribal Governments’’, (65 FR 67249), 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 PO 00000 Frm 00059 Fmt 4703 Sfmt 4703 57927 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. VII.

Preliminary Determination Regarding Energy Efficiency 
Improvements in the 2015 International Energy Conservation Code

AGENCY: Energy Efficiency and Renewable Energy, Department of Energy.

ACTION: Notice of Preliminary Determination.

-----------------------------------------------------------------------

SUMMARY: The U.S. Department of Energy (DOE) has preliminarily 
determined that the 2015 edition of the International Energy 
Conservation Code (IECC) would improve energy efficiency in buildings 
subject to the code compared to the 2012 edition. DOE analysis 
indicates that buildings meeting the 2015 IECC (as compared with 
buildings meeting the 2012 IECC) would result in national source energy 
savings of approximately 1.03 percent, site energy savings of 
approximately 1.12 percent, and energy cost savings of approximately 
0.90 percent of residential building energy consumption, as regulated 
by the IECC. If this determination is finalized, each State would be 
required by statute to certify that it has reviewed the provisions of 
its residential building code regarding energy efficiency, and made a 
determination as to whether to update their code to meet or exceed the 
2015 IECC. Additionally, this notice provides guidance to States on 
these processes and associated certifications.

I. Introduction

A. Statutory Authority

    Title III of the Energy Conservation and Production Act (ECPA), as 
amended, establishes requirements for building energy conservation 
standards, administered by the DOE Building Energy Codes Program. (42 
U.S.C. 6831 et seq.) Section 304(a), as amended, of ECPA provides that 
whenever the 1992 Model Energy Code (MEC), or any successor to that 
code, is revised, the Secretary of Energy (Secretary) must make a 
determination, not later than 12 months after such revision, whether 
the revised code would improve energy efficiency in residential 
buildings, and must publish notice of such determination in the Federal 
Register. (42 U.S.C. 6833(a)(5)(A)) The Secretary may determine that 
the revision of the 1992 MEC, or any successor thereof, improves the 
level of energy efficiency in residential buildings. If so, then not 
later than 2 years after the date of the publication of such 
affirmative determination, each State is required to certify that it 
has reviewed its residential building code regarding energy efficiency, 
and made a determination as to whether it is appropriate to revise its 
code to meet or exceed the provisions of the successor code. (42 U.S.C. 
6833(a)(5)(B)) State determinations are to be made: (1) After public 
notice and hearing; (2) in writing; (3) based upon findings included in 
such determination and upon evidence presented at the hearing; and (4) 
available to the public. (See 42 U.S.C. 6833(a)(2)) In addition, if a 
State determines that it is not appropriate to revise its residential 
building code, the State is required to submit to the Secretary, in 
writing, the reasons, which are to be made available to the public. 
(See 42 U.S.C. 6833(a)(4))
    ECPA 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(a) 
of ECPA, and that it has made significant progress in doing so. (42 
U.S.C. 6833(c)) DOE is also directed to provide technical assistance to 
States to support implementation of State residential and commercial 
building energy efficiency codes. (42 U.S.C. 6833(d))

B. Background

    The International Energy Conservation Code (IECC) is the national 
model code establishing energy efficiency requirements for residential 
buildings. The IECC is revised every 3 years through a code development 
and consensus process administered by the International Code Council 
(ICC).\1\ Code change proposals may be submitted by any interested 
party, and are evaluated through a series of public hearings. As part 
of the ICC process, any interested party may submit proposals, as well 
as written comments or suggested changes to any proposal, and make 
arguments before a committee of experts assembled by the ICC. At the 
final public hearing, arguments are presented to and voted upon by the 
ICC Governmental Member Representatives, with the collection of 
accepted proposals forming the revised edition of the IECC. The ICC 
published the 2015 edition of the IECC (2015 IECC or 2015 edition) on 
June 3, 2014, which forms the basis of this determination notice.
---------------------------------------------------------------------------

    \1\ More information on the ICC code development and consensus 
process is described at https://www.iccsafe.org/cs/codes/Pages/procedures.aspx
---------------------------------------------------------------------------

II. Methodology

    In arriving at a preliminary determination, DOE reviewed all 
changes between the 2015 and 2012 editions of the IECC. The IECC covers 
a broad spectrum of the energy-related components and systems in 
buildings, ranging from simpler residential buildings to more complex 
multifamily facilities. For the purposes of its preliminary 
determination, DOE focused only on low-rise residential buildings, 
defined in a manner consistent with the ICC and the American Society of 
Heating, Refrigerating and Air-conditioning Engineers (ASHRAE). Low-
rise residential buildings include one- and two-family detached and 
attached buildings, and low-rise multifamily buildings (not greater 
than three stories), such as condominiums and garden apartments. The 
2015 IECC was developed through the same approach as the previous 2012 
edition with approval through the ICC consensus process. The 2015 
edition contains no significant changes to the overall scope or the 
structure of the prescriptive and mandatory provisions of the code, 
which form the basis of the DOE determination analysis. As a result, 
DOE preliminarily determined that the methodology used for the analysis 
of the 2012 IECC should again be utilized for the analysis of the 2015 
IECC.
Overview of Methodology
    The analysis methodology used by DOE contains both qualitative and 
quantitative components. A qualitative comparison is undertaken to 
identify textual changes between requirements in the 2015 and 2012 
editions of the

[[Page 57917]]

IECC, followed by a quantitative assessment of energy savings conducted 
through whole-building simulations of buildings constructed to meet the 
minimum requirements of each code over a range of U.S. climates. The 
analysis methodology, which was previously developed through a public 
comment process, is available on the DOE Building Energy Codes Program 
Web site.\2\
---------------------------------------------------------------------------

    \2\ See https://www.energycodes.gov/development/residential/methodology.
---------------------------------------------------------------------------

    Consistent with its previous determinations, DOE compared overall 
editions of the IECC, and did not issue determinations for individual 
code changes. DOE interprets the language in section 304(a) of ECPA to 
mean that when a comprehensive revision of the 1992 MEC is published 
(which in this case is the 2015 IECC), then that revised or successor 
code triggers the Secretary's obligation to issue a determination as to 
whether the revised code improves energy efficiency in residential 
buildings. (See 42 U.S.C. 6833(a)(5)(A)) This determination is made by 
comparing the revised or successor code to the last predecessor code.
Consideration for Technological and Economic Factors
    Section 304(a) of ECPA states that the Secretary is required to 
make a determination as to whether any successor standard to the 1992 
MEC will improve energy efficiency. (42 U.S.C. 6833(a)(5)(A)) Section 
304 of ECPA does not include any reference to economic justification, 
although such criteria are considered directly by the ICC code 
development and consensus process, as applicable. Each proposal 
submitted to the ICC code development process also requires a 
declaration of whether the proposed code change will increase the cost 
of construction.
    Separate from the Secretary's determination under section 304(a), 
section 307 of ECPA requires DOE to periodically review the technical 
and economic basis of the voluntary building energy codes, and 
participate in the industry process for review and modification, 
including seeking adoption of all technologically feasible and 
economically justified energy efficiency measures. (42 U.S.C. 6836(b)) 
In fulfillment of this directive, DOE evaluates its code change 
proposals submitted to the ICC, analyzing energy savings and cost-
effectiveness, as applicable, and otherwise participates in the ICC 
process. In addition, DOE performs independent technical and economic 
analysis of the IECC as part of its direction to provide assistance to 
States implementing building energy codes. This approach allows DOE to 
meet its statutory obligation to participate in the industry process 
for review and modification of the IECC, and to seek adoption of all 
technologically feasible and economically justified energy efficiency 
measures. (42 U.S.C. 6836(b))
    In preparation for technical assistance activities, DOE previously 
developed a standardized methodology for assessing the cost-
effectiveness of code changes through a public process. (78 FR 47677) 
This methodology is published on the DOE Building Energy Codes Program 
Web site, and has been applied by DOE in the development of code change 
proposals for the IECC, as well as assessing the cost-effectiveness of 
published editions of the IECC. DOE expects to update this methodology 
periodically to ensure its assumptions and economic criteria remain 
valid and adequate for States considering adoption of model building 
energy codes.

III. Summary of Findings

    In performing its determination, DOE performed both a qualitative 
and quantitative analysis of the prescriptive and mandatory 
requirements contained in the 2015 IECC. The chosen methodology for 
these analyses is consistent with actions of recent determinations, and 
provides a reasonable assessment of how the code will affect energy 
savings in residential buildings. A summary of the analyses supporting 
DOE's determination is outlined in the following sections.
Qualitative Analysis
    DOE performed a comparative analysis of the textual requirements of 
the 2015 IECC, examining the specific changes (approved code changes) 
made between the 2012 and the 2015 editions. The ICC Code Hearing 
process considers individual code changes for approval, and then 
bundles all the approved code changes together to form the next 
published edition. In creating the 2015 IECC, ICC processed 77 approved 
code change proposals. DOE evaluated each of these code change 
proposals in preparing its determination.
    Overall, DOE found that the vast majority of changes in the 2015 
IECC appear to be neutral (i.e., have no direct impact on energy 
savings) within the context of the determination analysis. DOE also 
found that beneficial changes (i.e., increased energy savings) outweigh 
any changes with a detrimental effect on energy efficiency in 
residential buildings. Of the 77 total changes:
     6 were considered beneficial;
     62 were considered neutral;
     5 were considered negligible;
     3 were considered detrimental; and
     1 was considered to have an unquantifiable impact.
    Table III.1 presents the findings resulting from the qualitative 
analysis, along with a description of the change, as well as an 
assessment of the anticipated impact on energy savings in residential 
buildings. Additional details pertaining to the qualitative analysis 
are presented in a technical support document.\3\

(a) Code sections refer to the 2012 IECC.
KEY: The following terms are used to characterize the effect of individual code change on energy efficiency (as
  contained in the above table): Beneficial indicates that a code change is anticipated to improve energy
  efficiency; Detrimental indicates a code change may increase energy use in certain applications; Neutral
  indicates that a code change is not anticipated to impact energy efficiency; Negligible indicates a code
  change may have energy impacts but too small to quantify; and Not Quantifiable indicates that a code change
  may have energy impacts but cannot be quantified at this time.

    In addition to the changes approved for inclusion in the 
prescriptive and mandatory paths, ICC also approved a proposal based on 
an Energy Rating Index (ERI) in the 2015 IECC. While this change does 
not directly alter stringency of the code, it does provide an 
additional compliance path as an alternative to the IECC prescriptive 
and performance paths. DOE determination analyses have historically 
been based on the prescriptive compliance path. This has been done 
because: (1) The prescriptive compliance path is generally considered 
the predominant compliance path, and; (2) the performance path 
effectively allows a limitless number of ways to comply with the code, 
and no accepted methodology exists for how to analyze it. Equally 
important, there is no aggregated source of data allowing for 
documentation of how buildings meet the performance path criteria. In 
the absence of such data, an analysis of the performance path would 
have no empirical basis.
    The inclusion of a new type of compliance path in the 2015 IECC, 
which is based on an Energy Rating Index (ERI), prompted DOE to review 
its historical approach of using only the prescriptive path, and make a 
decision as to whether a change in methodology would be appropriate for 
the current determination analysis. Three primary points were 
considered:
    (1) The impact of the ERI path on national residential energy 
consumption is dependent on the number of homes that use this new path, 
and the unique building characteristics of those homes. As no 
jurisdiction has yet implemented the 2015 IECC, there is no way to know 
how many homes will use this path.
    (2) An analysis conducted by Pacific Northwest National Laboratory 
(PNNL) concluded that most homes built using the ERI path, as specified 
in the 2015 IECC, are likely to be at least as efficient as the homes 
built to meet the prescriptive requirements of the IECC or the 
traditional performance path.\4\

Corresponding to Minimal Compliance with the IECC (PNNL, Richland, 
WA, May 2014), available at https://www.energycodes.gov/hers-and-iecc-performance-path
---------------------------------------------------------------------------

    (3) Including the new ERI path but not the traditional performance 
path would be arbitrary relative to historical determination analysis. 
An accepted methodology, along with a supporting data source, by which 
to analyze the performance path would also be necessary, and is not 
currently available.
    Based on these three points, DOE concluded that it is appropriate 
to follow its historical approach for the current determination. 
However, DOE acknowledges that the landscape of code compliance may be 
changing, and therefore plans to track the implementation and 
application of the new ERI path, as well as collect relevant data that 
may enable DOE to further evaluate the ERI path in future analyses. DOE 
will also investigate the possibility of collecting data that could 
provide the basis for a broader analysis of performance-based 
compliance paths. Finally, DOE will explore whether the total number of 
homes built under each path can be determined and tracked over time. 
DOE anticipates that multiple paths may be considered in future 
determinations, but will only be included if the potential energy 
savings are large enough to significantly change the results that would 
occur from an analysis of prescriptive requirements.
    Table III.2 summarizes the overall impact of the code change 
proposals in the qualitative analysis. Overall, the sum of the 
beneficial code changes (6) is greater than the number of the 
detrimental code change proposals (3).

    The quantitative analysis of the 2015 IECC was carried out using 
whole-building energy simulations of prototype buildings designed to 
meet the requirements of the 2012 IECC and the 2015 IECC. DOE simulated 
32 representative residential building types across 15 U.S. climate 
locations, with locations selected to be representative of all U.S 
climate zones, as defined by the IECC. Energy use intensities (EUI) by 
fuel type and by end-use, as regulated by the IECC (i.e., heating, 
cooling, domestic water heating and lighting) were extracted for each 
building type, and weighted by the relative square footage of 
construction (represented by building type in each climate regions).
    The quantitative analysis of buildings designed to meet the 
requirements of the 2015 IECC indicates national site energy savings of 
1.12 percent of residential building energy consumption, as regulated 
by the IECC (in comparison to the 2012 IECC). Associated source energy 
savings are estimated to be approximately 1.03 percent, and national 
average energy cost savings are estimated to be approximately 0.90 
percent. Table III.3 and Table III.4 show the energy use and associated 
savings resulting from the 2015 IECC by climate zone and on an 
aggregated national basis. Further details on the quantitative analysis 
can be found in the technical support document.

IV. Preliminary Determination Statement

    Review and evaluation of the 2012 and 2015 editions of the IECC 
indicate that there are differences between the two editions. 
Qualitative analysis of the updated code reveals that many of the code 
changes are anticipated to have a neutral impact on energy efficiency, 
while a small number of code changes are anticipated to yield improved 
energy efficiency, and a smaller number of code changes are anticipated 
to be detrimental to energy efficiency. In addition, quantitative 
analysis of the code indicates regulated site energy, source energy, 
and energy cost savings of 1.12 percent, 1.03 percent and 0.90 percent, 
respectively. DOE has rendered the preliminary conclusion that the 2015 
IECC will improve energy efficiency in residential buildings, and, 
therefore, should receive an affirmative determination under Section 
304(a) of ECPA.

V. State Certification

    If today's determination is finalized, each State would be required 
to determine the appropriateness of revising the portion of its 
residential building code regarding energy efficiency to meet or exceed 
the energy efficiency provisions of the 2015 IECC. (42 U.S.C. 
6833(a)(5)(B)) This action must be made not later than 2 years from the 
date of publication of a Notice of Final Determination, unless an 
extension is provided.
State Review and Update
    The State determination must be: (1) Made after public notice and 
hearing; (2) in writing; (3) based upon findings and upon the evidence 
presented at the hearing; and (4) made available to the public. (42 
U.S.C. 6833(a)(2)) States have discretion with regard to the hearing 
procedures they use, subject to providing an adequate opportunity for 
members of the public to be heard and to present relevant information. 
The Department recommends publication of any notice of public hearing 
through appropriate and prominent media outlets, such as in a newspaper 
of general circulation. States should also be aware that this 
determination does not apply to IECC chapters specific to 
nonresidential buildings, as defined in the IECC. Therefore, if today's 
action is finalized, States must certify their evaluations of their 
State building codes for residential buildings with respect to all 
provisions of the IECC, except for those chapters not affecting 
residential buildings.
State Certification Statements
    If a State makes a determination that it is not appropriate to 
revise the energy efficiency provisions of its residential building 
code, the State must submit to the Secretary, in writing, the reasons 
for this determination and the statement shall be available to the 
public. (42 U.S.C. 6833(a)(4)) State certifications are to be sent to 
the address provided in the ADDRESSES section, or may be submitted to 
BuildingEnergyCodes@ee.doe.gov.
    The DOE Building Energy Codes Program tracks and reports State code 
adoption and certifications.\5\ Once a State has adopted an updated 
residential code, DOE typically provides software, training, and 
support for the new code, as long as the new code is based on the 
national model code (i.e., the 2015 IECC). DOE has issued previous 
guidance on how it intends to respond to technical assistance requests 
related to implementation resources, such as building energy code 
compliance software. (79 FR 15112) DOE also recognizes that 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 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. (See 42 U.S.C. 6833(e)) DOE does not prescribe how each 
State adopts and enforces its energy codes.

---------------------------------------------------------------------------

Requests for Extensions
    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, or may be submitted to 
BuildingEnergyCodes@ee.doe.gov.

VI. Regulatory Review and Analysis

Review Under Executive Orders 12866 and 13563
    Today's action is not a significant regulatory action under Section 
3(f) of Executive Order 12866, ``Regulatory Planning and Review'' (58 
FR 51735). Accordingly, today's action was not reviewed by the Office 
of Information and Regulatory Affairs (OIRA) in the Office of 
Management and Budget (OMB). DOE has also reviewed this regulation 
pursuant to Executive Order 13563, issued on January 18, 2011. (76 FR 
3281) Executive Order 13563 is supplemental to and explicitly reaffirms 
the principles, structures, and definitions governing regulatory review 
established in Executive Order 12866.
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), 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 also made its procedures and

[[Page 57926]]

policies available on the Office of General Counsel Web site.\6\
---------------------------------------------------------------------------

    \6\ Available at https://energy.gov/gc/office-general-counsel
---------------------------------------------------------------------------

    DOE has reviewed today's action under the provisions of the 
Regulatory Flexibility Act and the procedures and policies published in 
February 2003. Once DOE finalizes this determination of improved energy 
efficiency, it would require States to undertake an analysis of their 
respective building codes. As such, the only entities directly 
regulated by this 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. 
Based on the foregoing, DOE certifies that this preliminary 
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 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).
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 1992 
MEC, 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 residential 
buildings and must publish notice of such determination in the Federal 
Register. (42 U.S.C. 6833(a)(5)(A)) If the Secretary determines that 
the revision of 1992 MEC, or any successor thereof, improves the level 
of energy efficiency in residential buildings, then no later than 2 
years after the date of the publication of such affirmative 
determination, each State is required to certify that it has reviewed 
its residential building code regarding energy efficiency and made a 
determination whether it is appropriate to revise its code to meet or 
exceed the provisions of the successor code. (42 U.S.C. 6833(a)(5)(B)) 
Therefore, DOE has determined that this preliminary 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.
Review Under Executive Order 13132, ``Federalism''
    Executive Order 13132 (64 FR 43255) 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. 
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 
newly constructed buildings increases long-term 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 ensure, 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(a) of ECPA, DOE is statutorily required to 
determine whether the most recent edition of the MEC (or its successor) 
would improve the level of energy efficiency in residential buildings 
as compared to the previous edition. If DOE makes a positive 
determination, the statute requires each State to certify that it has 
reviewed its residential building code regarding energy efficiency and 
made a determination whether it is appropriate to revise its code to 
meet or exceed the provisions of the successor code. (42 U.S.C. 
6833(a)(5)(B))
    Executive Order 13132 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 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, the Secretary must 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. (See 42 U.S.C. 6833(e)) Therefore, 
consultation with States and local officials regarding this 
determination was not required.
    However, DOE notes that State and local governments were invited to 
participate in the development of the 2015 IECC. The IECC is developed 
in a national consensus process open to the public, and in which State 
and local governments may participate, along with the general public. 
The updated code is the product of a series of code change proposals to 
the prior edition of the code, with each change made available for 
public review, and with any interested party having the ability to 
participate and submit comments. Comments on the code change proposals 
and public comments are received, reviewed, and resolved through an 
established process administered by the ICC. Many representatives from 
State and local governments participate in the code development 
hearings. As directed by Congress, DOE believes that this process has 
given State and local jurisdictions extensive opportunity to comment 
and express any concerns on the 2015 IECC, the subject of this 
determination.
    Within two years from the issuance of a final determination that 
the 2015 IECC would improve the energy efficiency of residential 
buildings, ECPA requires each State to certify to the Secretary that it 
has reviewed its residential building code regarding energy efficiency, 
and made a determination whether it is appropriate to revise its code 
to meet or exceed the provisions of the successor code. DOE notes that 
ECPA sets forth

[[Page 57927]]

this requirement for States. (42 U.S.C. 6833(a)(5)(B)) States are given 
broad freedom to either adopt the IECC or develop their own code that 
meets or exceeds the IECC.
Review Under 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 an assessment of the anticipated costs and benefits 
of any rule that includes a Federal mandate that 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.
    Consistent with previous determinations, DOE has completed its 
review, and concluded that impacts on state, local, and tribal 
governments are less than the $100 million threshold specified in the 
Unfunded Mandates Act. Accordingly, no further action is required under 
the Unfunded Mandates Reform Act of 1995.
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.
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) 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. Both OMB and DOE have published established relevant guidelines 
(67 FR 8452 and 67 FR 62446, respectively). 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.
Review Under Executive Order 13211
    Executive Order 13211, ``Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use,'' (66 FR 
28355), 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 OMB 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.
Review Under Executive Order 13175
    Executive Order 13175, ``Consultation and Coordination with Indian 
tribal Governments'', (65 FR 67249), 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.

the information submitted. For information on submitting CBI, see the 
Confidential Business Information section below.
    DOE processes submissions made through Regulations.gov before 
posting.

[[Page 57928]]

Normally, comments will be posted within a few days of being submitted. 
However, if large volumes of comments are being processed 
simultaneously, your comment may not be viewable for up to several 
weeks. Please keep the comment tracking number that Regulations.gov 
provides after you have successfully uploaded your comment.
Submitting Comments via Email, Hand Delivery/Courier, or Mail
    Comments and documents submitted via email, hand delivery, or mail 
also will be posted to Regulations.gov. If you do not want your 
personal contact information to be publicly viewable, do not include it 
in your comment or any accompanying documents. Instead, provide your 
contact information in a cover letter, including your first and last 
names, email address, telephone number, and optional mailing address. 
The cover letter will not be publicly viewable as long as it does not 
include any comments.
    Include contact information each time you submit comments, data, 
documents, and other information to DOE. If you submit via mail or hand 
delivery/courier, please provide all items on a CD, if feasible. It is 
not necessary to submit printed copies. No facsimiles (faxes) will be 
accepted.
    Comments, data, and other information submitted to DOE 
electronically should be provided in PDF (preferred), Microsoft Word or 
Excel, WordPerfect, or text (ASCII) file format. Provide documents that 
are not secured, that are written in English, and that are free of any 
defects or viruses. Documents should not contain special characters or 
any form of encryption and, if possible, they should carry the 
electronic signature of the author.
Campaign Form Letters
    Please submit campaign form letters by the originating organization 
in batches of between 50 to 500 form letters per PDF or as one form 
letter with a list of supporters' names compiled into one or more PDFs. 
This reduces comment processing and posting time.
Confidential Business Information
    According to 10 CFR 1004.11, any person submitting information that 
he or she believes to be confidential and exempt by law from public 
disclosure should submit via email, postal mail, or hand delivery/
courier two well-marked copies: one copy of the document marked 
confidential including all the information believed to be confidential, 
and one copy of the document marked non-confidential with the 
information believed to be confidential deleted. Submit these documents 
via email or on a CD, if feasible. DOE will make its own determination 
about the confidential status of the information and treat it according 
to its determination.
    Factors of interest to DOE when evaluating requests to treat 
submitted information as confidential include: (1) A description of the 
items; (2) whether and why such items are customarily treated as 
confidential within the industry; (3) whether the information is 
generally known by or available from other sources; (4) whether the 
information has previously been made available to others without 
obligation concerning its confidentiality; (5) an explanation of the 
competitive injury to the submitting person which would result from 
public disclosure; (6) when such information might lose its 
confidential character due to the passage of time; and (7) why 
disclosure of the information would be contrary to the public interest.
    It is DOE's policy that all comments may be included in the public 
docket, without change and as received, including any personal 
information provided in the comments (except information deemed to be 
exempt from public disclosure).

    Issued in Washington, DC, on September 18, 2014.
Kathleen B. Hogan,
Deputy Assistant Secretary for Energy Efficiency, Energy Efficiency and 
Renewable Energy.
