Regulatory Review and Analysis VIII. Public Participation I. Statutory Authority Title III of the Energy Conservation and Production Act, as amended (ECPA), establishes requirements for building energy conservation standards, administered by the DOE Building Energy Codes 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 of Energy (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. PO 00000 Frm 00008 Fmt 4702 Sfmt 4702 27779 (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 2 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)) Each 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 shall meet or exceed the last revised Standard for which the Secretary has made an affirmative determination. (42 U.S.C. 6833(b)(2)(B)(ii)) On October 19, 2011, DOE published a final determination in the Federal Register updating the reference code to Standard 90.1–2010. (76 FR 64904) 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(c) 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)) II. Introduction ASHRAE and IES approved the publication of the 2013 edition of Energy Standard for Buildings Except Low-Rise Residential Buildings in October 2013. The Standard is developed under ANSI-approved consensus procedures,2 and is under continuous maintenance by a Standing Standard Project Committee. ASHRAE has established a program for regular publication of addenda, or revisions, including procedures for timely, documented, consensus action on requested changes to the Standard. ANSI approved the final addendum for inclusion in the 2013 edition in 2 An overview of the ANSI consensus process is available at https://www.ansi.org/standards_ activities/domestic_programs/overview. aspx?menuid=3.

Standard 90.1–2013 was published in October 2013.3 More information on ANSI/ASHRAE/IES Standard 90.1–2013 is available at: https://www.ashrae.org/resourcespublications/bookstore/standard-90-1. TKELLEY on DSK3SPTVN1PROD with PROPOSALS III. Methodology In arriving at a preliminary determination, DOE reviewed all changes between the 2013 and 2010 editions of Standard 90.1. Standard 90.1 is complex and covers a broad spectrum of the energy-related components and systems in buildings, ranging from simpler commercial buildings to more complex hospitals and laboratory facilities. Standard 90.1–2013 was developed through the same approach as the previous 2010 edition, which involves committee approval through a consensus process consistent with ANSI procedures for developing industry standards. The 2013 edition contains no significant changes to the overall scope or the structure of the Standard. As a result, DOE preliminarily determined that the methodology used for the analysis of Standard 90.1–2010 should again be utilized for the analysis of Standard 90.1–2013. 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 Standard 90.1–2013 and Standard 90.1–2010, followed by a quantitative assessment of energy savings conducted through whole-building simulations of buildings constructed to meet the minimum requirements of each Standard over the range of U.S. climates. A discussion of the analysis methodology, which was developed through public comment in past DOE determinations, can be found in the Notice of Preliminary Determination for Standard 90.1–2007 (75 FR 54117) and Notice of Preliminary Determination for Standard 90.1–2010 (76 FR 43298). Consistent with its previous determinations, DOE compared overall editions of Standard 90.1. DOE interprets the language in Section 304(b)(2) of ECPA to mean that when a comprehensive revision of the ASHRAE Standard is published (which in this case is ASHRAE Standard 90.1–2013), then that revised or successor Standard triggers the Secretary’s obligation to issue a determination as to whether the revised Standard improves energy 3 ASHRAE press release available at https:// www.ashrae.org/news/2013/ashrae-ies-publish2013-energy-standard-changes-for-envelopelighting-mechanical-sections. VerDate Mar<15>2010 17:07 May 14, 2014 Jkt 232001 efficiency in commercial buildings. (See 42 U.S.C. 6833(b)(2)(A)) This determination is made by comparing the revised or successor Standard to the last predecessor Standard. While the continuous addenda review and update process is part of the ongoing maintenance of the Standard, DOE does not interpret each addendum update after the release of the full standard as an additional ‘‘revised or successor standard’’ requiring a determination by the Secretary. Consideration for Technological and Economic Factors Section 304(b) of ECPA states that the Secretary is required to make a determination as to whether any successor standard to ASHRAE Standard 90.1–1989 will improve energy efficiency. (42 U.S.C. 6833(b)(2)(A)) Section 304 of ECPA does not include any reference to economic justification. Separate from the Secretary’s determination under section 304(b), section 307 of ECPA requires DOE to periodically review the 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)) DOE fulfills this obligation in two ways. First, the ASHRAE process, in which DOE participates, provides consideration for the feasibility and economics of proposed addenda, with a defined methodology applied to test the cost-effectiveness of individual addenda. Next, DOE performs independent analysis of Standard 90.1 as part of its direction to assist States implementing building energy codes. (ASHRAE consideration for costeffectiveness and technical assistance provided by DOE is further explained below.) The development of ASHRAE standards is based upon the ANSI consensus process, which ensures participation by any interested party, with representatives classified as producer (e.g., industry), user (e.g., owners and designers), and general (e.g., government representatives or other general interests) segments of the building industry coming together to develop a consensus-based standard. DOE is an active participant in this process, and provided technical support to the development of the Standard through Pacific Northwest National Laboratory (PNNL). This approach allows DOE to meet its statutory obligation to participate in the industry process to review and modify Standard PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 90.1, and to seek adoption of all technologically feasible and economically justified energy efficiency measures. (42 U.S.C. 6836(b)) The ASHRAE development process requires extensive committee deliberation and public review of each change to Standard 90.1, including consideration for the cost-effectiveness of proposed changes. One of the objectives considered by the committee developing Standard 90.1 is for the requirements of the Standard to be costeffective for use in the public and private sectors. In recent years, one of the primary support functions provided by PNNL is assistance in the development of cost-effectiveness analyses that are considered by the development committee. Some proposed changes to the Standard do not require a cost-effectiveness evaluation, such as the following: • Changes that do not add cost to the building or where the added cost would be negligible; • Changes intending to clarify existing requirements of the Standard or to improve compliance with existing requirements of the Standard; • Changes to external references that are included in the Standard; or • Changes that reflect Federal requirements, such as appliance and commercial equipment standards. When evaluating proposed changes to the Standard where an additional cost to the building is anticipated, Standard 90.1 uses a defined methodology known as the Scalar Method 4 to ensure that Standard 90.1 is cost effective. This method is based on ASTM Standard E917—Standard Practice for Measuring Life-Cycle Costs of Buildings and Building Systems. Standard 90.1 has simplified the life-cycle cost (LCC) model in ASTM Standard E917 by condensing the economic variables into a single variable called the Scalar Ratio, which is simply a ratio of economic present worth factors. A maximum scalar ratio of 21.9, corresponding to a measure life of 40 years was used in the development of Standard 90.1–2013. This ratio is mathematically equivalent to a LCC analysis using the following parameters: 4 M.F. McBride, ‘‘Development of Economic Scalar Ratios for ASHRAE Standard 90.1 R,’’ (presented at the Thermal Performance of the Exterior Envelopes of Buildings VI, ASHRAE, 1995), available at https://consensus.fsu.edu/FBC/ 2010-Florida-Energy-Code/901_Scalar_Ratio_ Development.pdf .

If the scalar ratio for a particular measure is less than the scalar ratio limit established by the measure life and the parameters presented above, then the measure is considered cost-effective. The scalar ratio for a proposal is determined by the following equation: the cost effectiveness of building energy codes (78 FR 47677), and expects to update this method to ensure its assumptions and economic criteria remain valid and adequate for States considering adoption of model building energy codes. DOE is specifically requesting public comments and additional information regarding the costs and benefits of the use of Standard 90.1–2013, as a whole, and appropriate methodologies for assessing costs, benefits, and cost-effectiveness in the Public Participation section of this notice. Qualitative Analysis DOE performed a comparative analysis of the textual requirements of Standard 90.1–2013, examining the specific changes (addenda) made between Standard 90.1–2010 and Standard 90.1–2013. ASHRAE publishes changes to its standards as individual addenda to the preceding Standard, and then bundles all addenda together to form the next published edition. In creating the 2013 edition, ASHRAE processed 110 total addenda. DOE evaluated each of these addenda in preparing this preliminary determination. Overall, DOE found that the vast majority of changes in creating Standard 90.1–2013 were positive (i.e., increased energy savings) or neutral (i.e., no direct impact on energy savings). Positive changes significantly outweigh any changes with a negative effect on energy efficiency in commercial buildings. Of the 110 total changes: • 52 were considered positive; • 53 were considered neutral; and • 5 were considered negative. Table IV.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 commercial buildings. The full qualitative analysis is presented in a separate technical support document (TSD),6 available at https:// www.energycodes.gov/regulations/ determinations. 5 Thornton et al., Cost-Effectiveness of ASHRAE Standard 90.1–2010 Compared to ASHRAE Standard 90.1–2007 (PNNL, Richland, WA (US), November 2013), available at https://www.pnnl.gov/ main/publications/external/technical_reports/pnnl22972.pdf. 6 Halverson et al., ANSI/ASHRAE/IES Standard 90.1–2013 Preliminary Determination: Qualitative Analysis (PNNL, Richland, WA (US), March 2014), available at https://www.pnnl.gov/main/ publications/external/technical_reports/pnnl23198.pdf.

Summary of Findings In performing its preliminary determination, DOE performed both a qualitative and quantitative analysis of the requirements contained in the updated edition of Standard 90.1. The chosen methodology for these analyses is consistent with recent determinations actions, and provides a reasonable assessment of how the Standard will impact energy savings in commercial buildings. A summary of the analyses supporting DOE’s preliminary determination is outlined in the following sections.

However, this information is often desired by States to inform processes to update State energy codes. To address this need, and as part of DOE’s direction to provide technical assistance to support the implementation of State energy efficiency codes (42 U.S.C. 6833(d)), DOE has worked with States to help them understand the energy and economic impacts associated with updated model energy codes. This approach allows DOE and the States to identify and collect necessary data, as available, and work with individual States to understand localized costs, construction practices, and unique State scenarios. DOE provided such Statelevel cost-effectiveness analysis for States considering adoption of recent editions of Standard 90.1,5 and plans to provide similar analysis for the 2013 edition by December 31, 2014. In preparation for future technical assistance activities, DOE is interested in receiving stakeholder feedback on the Department’s practice of providing costeffectiveness analysis to support State energy code adoption. DOE has issued past requests for information to guide the Department in establishing an appropriate methodology for evaluating 27782 Federal Register / Vol. 79, No. 94 / Thursday, May 15, 2014 / Proposed Rules TABLE IV.1—QUALITATIVE ANALYSIS FINDINGS Addendum to Standard 90.1–2010 Sections affected within the Standard Description of changes Impact on energy efficiency (justification) 1 ................ 90.1–2010a 10.

Requires escalators and moving walks to automatically slow when not conveying passengers. The corresponding reference to American Society of Mechanical Engineers (ASME) A17.1/CSA B44 has also been added to the Normative References. Adds requirements for laboratory exhaust fans to Section G3.1.1, Baseline HVAC System Type and Definition. Lab exhaust fans are required to be modeled as constant horsepower, reflecting constant volume stack discharge with outside air bypass. Updates language in Section G3.1, part 5, ‘‘Building Envelope,’’ to require that existing buildings use the same envelope baseline as new buildings with the exception of fenestration area. Modifies Section G.3.1, ‘‘Building Envelope.’’ Specifies the vertical fenestration area for calculating baseline building performance for new buildings and additions. Adds efficiency requirements for commercial refrigerators, freezers, and refrigeration equipment. Table 6.8.1L and Table 6.8.1M (now Tables 6.8.1–12 and 6.8.1–13 in Standard 90.1–2013) have been added, which specify the energy use limits for refrigerators and freezers. The corresponding references have also been added in Chapter 12. Modifies the minimum efficiency standards for water-to-air heat pumps (water loop, ground water, and ground loop). The proposed cooling energy efficiency ratios (EERs) and heating coefficients of performance are more stringent than the present values. Also removes the small duct high velocity heat pump product class from Table 6.8.1B (now Table 6.8.1–2 in Standard 90.1– 2013). Increases the minimum efficiency standards for single-package vertical air conditioners (SPVAC) and single-package vertical heat pumps (SPVHP). Also creates a new product class for SPVAC and SPVHP used in space-constrained applications. This new product class only applies to non-weatherized products with cooling capacities <36,000 British thermal units per hour (Btu/h) and intended to replace an existing air-conditioning (AC) unit. Modifies the minimum efficiency requirements of evaporatively cooled units, of size category 240,000 Btu/h to 760,000 Btu/h and heating typeother, in Table 6.8.1A (now Table 6.8.1–1 in Standard 90.1–2013). The value is reduced to account for increased pressure drop in such system types. The product class, small duct high velocity air conditioner, has been eliminated. Modifies notes to Table 8.1 and specifies that nominal efficiencies would be established in accordance with the 10 CFR 431 test procedure for lowvoltage dry-type transformers. The corresponding references have also been added in Chapter 12.

TKELLEY on DSK3SPTVN1PROD with PROPOSALS Key: The following terms are used to characterize the effect of individual addenda on energy efficiency (as contained in the above table): Major + indicates that an addendum is anticipated to significantly improve energy efficiency; Minor + indicates that an addendum may improve energy efficiency in specific applications, Neutral indicates that an addenda is not anticipated to impact energy efficiency; and Minor ¥ indicates that an addendum may increase energy use in certain applications. Table IV.2 summarizes the overall impact of the addenda in the qualitative analysis. Overall, the sum of the major positive and minor positive addenda (i.e., 52 addenda) greatly overwhelms the number of minor negative addenda (i.e., five addenda), leading to the qualitative conclusion that the overall impact of the addenda on the Standard is positive.

DOE simulated 16 representative building types across 15 U.S. climate locations, with locations selected to be representative of all U.S climate zones, as defined by Standard 90.1–2010 and Standard 90.1–2013 (climate zone criteria unchanged between the 2010 and 2013 editions). In addition, energy use intensities (EUIs) by fuel type and by end-use were extracted for each building type, and weighted by the relative square footage of construction (represented by that building type in each of the 15 climate regions) based on the McGraw Hill Construction (MHC) Projects Starts Database.7 The data is commonly 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), to characterize U.S. building construction. In addition, the MHC database identifies multi-family residential buildings that would be covered under the scope of Standard 90.1. EUIs developed for each representative building type are weighted by total national square footage of each representative building type to estimate the difference between the national energy use in buildings constructed to the 2010 and 2013 editions of Standard 90.1. Note that the buildings types used in the quantitative analysis reflect approximately 80% of the total square footage of commercial construction, including multi-family buildings greater than three stories that are covered within the scope of ASHRAE Standard 90.1. The preliminary quantitative analysis of buildings designed to meet the requirements of Standard 90.1–2013 indicates national primary energy savings of approximately 8.5 percent of commercial building energy consumption (in comparison to Standard 90.1–2010). Site energy savings over Standard 90.1–2010 are estimated to be approximately 7.6 percent. Using national average fuel prices for electricity and natural gas, DOE also estimates a reduction in energy expenditures of 8.7 percent compared to Standard 90.1–2010. Table IV.3 and Table IV.4 show the energy use and associated savings resulting from Standard 90.1–2013 by building type and on an aggregated national basis. Further details on the quantitative analysis can be found in the full technical support document (TSD) 8 available at https:// www.energycodes.gov/regulations/ determinations.

Preliminary Determination Statement Review and evaluation of the 2010 and 2013 editions of Standard 90.1 indicate that there are significant differences between the two editions. Qualitative analysis of the updated Standard reveals that a majority of the addenda are anticipated to result in significant energy savings. In addition, quantitative analysis of the Standard indicates source and site energy savings of 8.5 percent and 7.6 percent, respectively. DOE has rendered the preliminary conclusion that Standard 90.1–2013 will improve energy efficiency in commercial buildings, and, therefore, should receive an affirmative determination under Section 304(b) of ECPA.

State Certification If today’s determination is finalized, each State would be required to review and update, as necessary, the provisions of its commercial building energy code to meet or exceed the provisions of the 2013 edition of Standard 90.1. (42 U.S.C. 6833(b)(2)(B)(i)) This action would be required not later than 2 years from the date of the final determination notice, unless an extension is provided. State Review and Update 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 PO 00000 Frm 00020 Fmt 4702 Sfmt 4702 Source EUI 11.0 7.4 1.4 13.9 8.8 8.1 12.6 3.6 5.6 5.7 8.0 6.0 2.6 3.0 5.4 6.9 7.6 11.0 7.5 2.4 12.8 10.2 11.0 14.1 3.9 6.4 7.5 10.2 6.1 4.7 3.9 5.1 8.4 8.5 ECI 11.0 7.5 2.5 12.6 10.5 11.5 14.4 3.9 6.5 7.9 10.7 6.1 5.3 4.2 5.0 8.7 8.7 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 2013 edition of Standard 90.1. States may base their certifications on reasonable actions by units of generalpurpose local government. Each such State must review the information obtained from the local governments, and gather any additional data and testimony in preparing its own certification. The applicability of any State revisions to new or existing buildings would be governed by the State building codes. States should be aware that the DOE considers high-rise (greater than three stories) multi-family residential buildings as commercial buildings for E:\FR\FM\15MYP1.SGM 15MYP1 27792 Federal Register / Vol. 79, No. 94 / Thursday, May 15, 2014 / Proposed Rules energy code purposes, as is consistent with the scope of Standard 90.1. Consequently, commercial buildings, for the purposes of certification, would include high-rise multi-family residential buildings, hotels, motels, and other transient residential building types of any height. TKELLEY on DSK3SPTVN1PROD with PROPOSALS State Certification Statements 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 90.1–2013. (42 U.S.C. 6833(b)) The certification must include a demonstration that the provisions of the State’s commercial building energy code regarding energy efficiency meets or exceeds Standard 90.1–2013. If a State intends to certify that its commercial building energy code already meets or exceeds the requirements of Standard 90.1–2013, the State should provide an explanation of the basis for this certification (e.g., Standard 90.1–2013 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 (e.g., director of the State energy office, State code commission, utility commission, or equivalent State agency having primary responsibility for commercial building energy codes), would provide the certification to the Secretary. Such a designated State official would also provide the certifications regarding the codes of units of general purpose local government based on information provided by responsible local officials. The DOE Building Energy Codes Program tracks and reports State code adoption and certifications.9 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 code (i.e., ASHRAE Standard 90.1–2013). DOE 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 does provide incentive funding (e.g., grants) to these States through the State Energy Program. DOE does not prescribe how each State adopts and enforces its energy codes. 9 Available at https://www.energycodes.gov/ adoption/states. VerDate Mar<15>2010 17:07 May 14, 2014 Jkt 232001 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 above, or may be submitted to BuildingEnergyCodes@ ee.doe.gov. VII. 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 PO 00000 Frm 00021 Fmt 4702 Sfmt 4702 policies available on the Office of General Counsel Web site.10 DOE has reviewed today’s preliminary determination under the provisions of the Regulatory Flexibility Act and the procedures and policies published in February 2003. Once DOE finalizes this preliminary 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 preliminary 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 preliminary 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 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 2 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 10 Available at https://energy.gov/gc/office-generalcounsel. E:\FR\FM\15MYP1.SGM 15MYP1 Federal Register / Vol. 79, No. 94 / Thursday, May 15, 2014 / Proposed Rules TKELLEY on DSK3SPTVN1PROD with PROPOSALS 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. 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. DOE has reviewed the statutory authority, and 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(b) of ECPA, DOE is statutorily required to determine whether the most recent edition of Standard 90.1 would improve the level of energy efficiency in commercial VerDate Mar<15>2010 17:07 May 14, 2014 Jkt 232001 buildings as compared to the previous edition. 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 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, 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 preliminary determination was not required. However, DOE notes that State and local governments were invited to participate in the development Standard 90.1–2013. The ASHRAE Standard is developed in a national, ANSI-approved consensus process open to the public, and in which State and local governments may participate, along with the general public. The updated Standard is the product of a series of amendments to the prior edition of the Standard, with each addendum made available for public review with any interested party having the ability to submit comments. Comments on the addendum are received, reviewed, and resolved through an established process commonly utilized in generating industry consensus standards. Members of the Standard 90.1 project committee have included representatives of State and local governments. DOE believes that this process has given State and local jurisdictions extensive opportunity to comment and express any concerns on Standard 90.1–2013, the subject of this preliminary determination. On issuance of a final determination that Standard 90.1–2013 would improve PO 00000 Frm 00022 Fmt 4702 Sfmt 4702 27793 the energy efficiency of commercial buildings, ECPA requires each State 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 90.1–2013. 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– 2013 or develop their own code that meets or exceeds Standard 90.1–2013. 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. Documentation supporting this review is contained in Appendix D of the full Quantitative Analysis technical support document (TSD) 11 available at https:// 11 Halverson et al., ANSI/ASHRAE/IES Standard 90.1–2013 Preliminary Determination: Quantitative Analysis (PNNL, Richland, WA (US), March 2014), E:\FR\FM\15MYP1.SGM Continued 15MYP1 27794 Federal Register / Vol. 79, No. 94 / Thursday, May 15, 2014 / Proposed Rules www.energycodes.gov/regulations/ determinations. 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 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. TKELLEY on DSK3SPTVN1PROD with PROPOSALS 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 available at https://www.pnnl.gov/main/ publications/external/technical_reports/pnnl23236.pdf. VerDate Mar<15>2010 17:07 May 14, 2014 Jkt 232001 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. VIII.

Preliminary Determination Regarding Energy Efficiency 
Improvements in ANSI/ASHRAE/IES Standard 90.1-2013: Energy Standard for 
Buildings, Except Low-Rise Residential Buildings

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 2013 edition of the ANSI/ASHRAE/IES \1\ Standard 
90.1:

[[Page 27779]]

Energy Standard for Buildings, Except Low-Rise Residential Buildings 
would improve energy efficiency in buildings subject to the code 
compared to the 2010 edition of Standard 90.1. DOE has preliminarily 
determined that buildings built to Standard 90.1-2013, as compared with 
buildings built to Standard 90.1-2010, would result in national source 
energy savings of approximately 8.5 percent and site energy savings of 
approximately 7.6 percent of commercial building energy consumption. If 
this determination is finalized, States would be required to certify 
that they have reviewed the provisions of their commercial building 
code regarding energy efficiency, and, as necessary, updated their 
codes to meet or exceed Standard 90.1-2013. Additionally, this notice 
provides guidance to States on certifications and requests for 
extensions of deadlines for certification statements.

I. Statutory Authority

    Title III of the Energy Conservation and Production Act, as amended 
(ECPA), establishes requirements for building energy conservation 
standards, administered by the DOE Building Energy Codes 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 of Energy (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 2 
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)) Each 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 shall meet or exceed the last revised Standard for 
which the Secretary has made an affirmative determination. (42 U.S.C. 
6833(b)(2)(B)(ii)) On October 19, 2011, DOE published a final 
determination in the Federal Register updating the reference code to 
Standard 90.1-2010. (76 FR 64904)
    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(c) 
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))

II. Introduction

    ASHRAE and IES approved the publication of the 2013 edition of 
Energy Standard for Buildings Except Low-Rise Residential Buildings in 
October 2013. The Standard is developed under ANSI-approved consensus 
procedures,\2\ and is under continuous maintenance by a Standing 
Standard Project Committee. ASHRAE has established a program for 
regular publication of addenda, or revisions, including procedures for 
timely, documented, consensus action on requested changes to the 
Standard. ANSI approved the final addendum for inclusion in the 2013 
edition in

[[Page 27780]]

September 2013. Standard 90.1-2013 was published in October 2013.\3\

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

III. Methodology

    In arriving at a preliminary determination, DOE reviewed all 
changes between the 2013 and 2010 editions of Standard 90.1. Standard 
90.1 is complex and covers a broad spectrum of the energy-related 
components and systems in buildings, ranging from simpler commercial 
buildings to more complex hospitals and laboratory facilities. Standard 
90.1-2013 was developed through the same approach as the previous 2010 
edition, which involves committee approval through a consensus process 
consistent with ANSI procedures for developing industry standards. The 
2013 edition contains no significant changes to the overall scope or 
the structure of the Standard. As a result, DOE preliminarily 
determined that the methodology used for the analysis of Standard 90.1-
2010 should again be utilized for the analysis of Standard 90.1-2013.

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 Standard 90.1-2013 and 
Standard 90.1-2010, followed by a quantitative assessment of energy 
savings conducted through whole-building simulations of buildings 
constructed to meet the minimum requirements of each Standard over the 
range of U.S. climates. A discussion of the analysis methodology, which 
was developed through public comment in past DOE determinations, can be 
found in the Notice of Preliminary Determination for Standard 90.1-2007 
(75 FR 54117) and Notice of Preliminary Determination for Standard 
90.1-2010 (76 FR 43298).
    Consistent with its previous determinations, DOE compared overall 
editions of Standard 90.1. DOE interprets the language in Section 
304(b)(2) of ECPA to mean that when a comprehensive revision of the 
ASHRAE Standard is published (which in this case is ASHRAE Standard 
90.1-2013), then that revised or successor Standard triggers the 
Secretary's obligation to issue a determination as to whether the 
revised Standard improves energy efficiency in commercial buildings. 
(See 42 U.S.C. 6833(b)(2)(A)) This determination is made by comparing 
the revised or successor Standard to the last predecessor Standard. 
While the continuous addenda review and update process is part of the 
ongoing maintenance of the Standard, DOE does not interpret each 
addendum update after the release of the full standard as an additional 
``revised or successor standard'' requiring a determination by the 
Secretary.

Consideration for Technological and Economic Factors

    Section 304(b) of ECPA states that the Secretary is required to 
make a determination as to whether any successor standard to ASHRAE 
Standard 90.1-1989 will improve energy efficiency. (42 U.S.C. 
6833(b)(2)(A)) Section 304 of ECPA does not include any reference to 
economic justification.
    Separate from the Secretary's determination under section 304(b), 
section 307 of ECPA requires DOE to periodically review the 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)) DOE fulfills this 
obligation in two ways. First, the ASHRAE process, in which DOE 
participates, provides consideration for the feasibility and economics 
of proposed addenda, with a defined methodology applied to test the 
cost-effectiveness of individual addenda. Next, DOE performs 
independent analysis of Standard 90.1 as part of its direction to 
assist States implementing building energy codes. (ASHRAE consideration 
for cost-effectiveness and technical assistance provided by DOE is 
further explained below.)
    The development of ASHRAE standards is based upon the ANSI 
consensus process, which ensures participation by any interested party, 
with representatives classified as producer (e.g., industry), user 
(e.g., owners and designers), and general (e.g., government 
representatives or other general interests) segments of the building 
industry coming together to develop a consensus-based standard. DOE is 
an active participant in this process, and provided technical support 
to the development of the Standard through Pacific Northwest National 
Laboratory (PNNL). This approach allows DOE to meet its statutory 
obligation to participate in the industry process to review and modify 
Standard 90.1, and to seek adoption of all technologically feasible and 
economically justified energy efficiency measures. (42 U.S.C. 6836(b))
    The ASHRAE development process requires extensive committee 
deliberation and public review of each change to Standard 90.1, 
including consideration for the cost-effectiveness of proposed changes. 
One of the objectives considered by the committee developing Standard 
90.1 is for the requirements of the Standard to be cost-effective for 
use in the public and private sectors. In recent years, one of the 
primary support functions provided by PNNL is assistance in the 
development of cost-effectiveness analyses that are considered by the 
development committee. Some proposed changes to the Standard do not 
require a cost-effectiveness evaluation, such as the following:
     Changes that do not add cost to the building or where the 
added cost would be negligible;
     Changes intending to clarify existing requirements of the 
Standard or to improve compliance with existing requirements of the 
Standard;
     Changes to external references that are included in the 
Standard; or
     Changes that reflect Federal requirements, such as 
appliance and commercial equipment standards.
    When evaluating proposed changes to the Standard where an 
additional cost to the building is anticipated, Standard 90.1 uses a 
defined methodology known as the Scalar Method \4\ to ensure that 
Standard 90.1 is cost effective. This method is based on ASTM Standard 
E917--Standard Practice for Measuring Life-Cycle Costs of Buildings and 
Building Systems. Standard 90.1 has simplified the life-cycle cost 
(LCC) model in ASTM Standard E917 by condensing the economic variables 
into a single variable called the Scalar Ratio, which is simply a ratio 
of economic present worth factors. A maximum scalar ratio of 21.9, 
corresponding to a measure life of 40 years was used in the development 
of Standard 90.1-2013. This ratio is mathematically equivalent to a LCC 
analysis using the following parameters:
---------------------------------------------------------------------------

    \4\ M.F. McBride, ``Development of Economic Scalar Ratios for 
ASHRAE Standard 90.1 R,'' (presented at the Thermal Performance of 
the Exterior Envelopes of Buildings VI, ASHRAE, 1995), available at 
https://consensus.fsu.edu/FBC/2010-Florida-Energy-Code/901_Scalar_Ratio_Development.pdf .

[[Page 27781]]



          Table III.1--ASHRAE Scalar Ratio Economic Parameters
------------------------------------------------------------------------
               Parameter                          Rate (percent)
------------------------------------------------------------------------

Heating Fuel Escalation Rate...........  3.76.
Cooling Fuel Escalation Rate...........  3.76.
Federal Tax Rate.......................  34.
State Tax Rate.........................  6.5.
Nominal Discount Rate..................  7.
Real Discount Rate.....................  6.05.
------------------------------------------------------------------------

    The above economic parameters are vetted and updated by ASHRAE at 
the beginning of each three-year Standard 90.1 development cycle. If 
the scalar ratio for a particular measure is less than the scalar ratio 
limit established by the measure life and the parameters presented 
above, then the measure is considered cost-effective. The scalar ratio 
for a proposal is determined by the following equation:
[GRAPHIC] [TIFF OMITTED] TP15MY14.008

    It should be noted that Standard 90.1 evaluates the cost-
effectiveness of individual addenda, as applicable, but does not 
evaluate the cost-effectiveness of the Standard as a whole. However, 
this information is often desired by States to inform processes to 
update State energy codes. To address this need, and as part of DOE's 
direction to provide technical assistance to support the implementation 
of State energy efficiency codes (42 U.S.C. 6833(d)), DOE has worked 
with States to help them understand the energy and economic impacts 
associated with updated model energy codes. This approach allows DOE 
and the States to identify and collect necessary data, as available, 
and work with individual States to understand localized costs, 
construction practices, and unique State scenarios. DOE provided such 
State-level cost-effectiveness analysis for States considering adoption 
of recent editions of Standard 90.1,\5\ and plans to provide similar 
analysis for the 2013 edition by December 31, 2014.

    In preparation for future technical assistance activities, DOE is 
interested in receiving stakeholder feedback on the Department's 
practice of providing cost-effectiveness analysis to support State 
energy code adoption. DOE has issued past requests for information to 
guide the Department in establishing an appropriate methodology for 
evaluating the cost effectiveness of building energy codes (78 FR 
47677), and expects to update this method to ensure its assumptions and 
economic criteria remain valid and adequate for States considering 
adoption of model building energy codes. DOE is specifically requesting 
public comments and additional information regarding the costs and 
benefits of the use of Standard 90.1-2013, as a whole, and appropriate 
methodologies for assessing costs, benefits, and cost-effectiveness in 
the Public Participation section of this notice.

IV. Summary of Findings

    In performing its preliminary determination, DOE performed both a 
qualitative and quantitative analysis of the requirements contained in 
the updated edition of Standard 90.1. The chosen methodology for these 
analyses is consistent with recent determinations actions, and provides 
a reasonable assessment of how the Standard will impact energy savings 
in commercial buildings. A summary of the analyses supporting DOE's 
preliminary determination is outlined in the following sections.

Qualitative Analysis

    DOE performed a comparative analysis of the textual requirements of 
Standard 90.1-2013, examining the specific changes (addenda) made 
between Standard 90.1-2010 and Standard 90.1-2013. ASHRAE publishes 
changes to its standards as individual addenda to the preceding 
Standard, and then bundles all addenda together to form the next 
published edition. In creating the 2013 edition, ASHRAE processed 110 
total addenda. DOE evaluated each of these addenda in preparing this 
preliminary determination.
    Overall, DOE found that the vast majority of changes in creating 
Standard 90.1-2013 were positive (i.e., increased energy savings) or 
neutral (i.e., no direct impact on energy savings). Positive changes 
significantly outweigh any changes with a negative effect on energy 
efficiency in commercial buildings. Of the 110 total changes:
     52 were considered positive;
     53 were considered neutral; and
     5 were considered negative.
    Table IV.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 commercial 
buildings. The full qualitative analysis is presented in a separate 
technical support document (TSD),\6\ available at https://www.energycodes.gov/regulations/determinations.

Key: The following terms are used to characterize the effect of individual addenda on energy efficiency (as
  contained in the above table): Major + indicates that an addendum is anticipated to significantly improve
  energy efficiency; Minor + indicates that an addendum may improve energy efficiency in specific applications,
  Neutral indicates that an addenda is not anticipated to impact energy efficiency; and Minor - indicates that
  an addendum may increase energy use in certain applications.

    Table IV.2 summarizes the overall impact of the addenda in the 
qualitative analysis. Overall, the sum of the major positive and minor 
positive addenda (i.e., 52 addenda) greatly overwhelms the number of 
minor negative addenda (i.e., five addenda), leading to the qualitative 
conclusion that the overall impact of the addenda on the Standard is 
positive.

Quantitative Analysis

    The quantitative analysis of Standard 90.1-2013 was carried out 
using whole-building energy simulations of buildings designed to meet 
the requirements of Standard 90.1-2010 and Standard 90.1-2013. DOE 
simulated 16 representative building types across 15 U.S. climate 
locations, with locations selected to be representative of all U.S 
climate zones, as defined by Standard 90.1-2010 and Standard 90.1-2013 
(climate zone criteria unchanged between the 2010 and 2013 editions). 
In addition, energy use intensities (EUIs) by fuel type and by end-use 
were extracted for each building type, and weighted by the relative 
square footage of construction (represented by that building type in 
each of the 15 climate regions) based on the McGraw Hill Construction 
(MHC) Projects Starts Database.\7\ The data is commonly 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), to 
characterize U.S. building construction. In addition, the MHC database 
identifies multi-family residential buildings that would be covered 
under the scope of Standard 90.1.

the Development of ANSI/ASHRAE/IESNA Standard 90.1-2010 by Jarnagin,

National Laboratory, Richland, WA. Available at https://www.pnl.gov/main/publications/external/technical_reports/PNNL-19116.pdf.
---------------------------------------------------------------------------

    EUIs developed for each representative building type are weighted 
by total national square footage of each representative building type 
to estimate the difference between the national energy use in buildings 
constructed to the 2010 and 2013 editions of Standard 90.1. Note that 
the buildings types used in the quantitative analysis reflect 
approximately 80% of the total square footage of commercial 
construction, including multi-family buildings greater than three 
stories that are covered within the scope of ASHRAE Standard 90.1.
    The preliminary quantitative analysis of buildings designed to meet 
the requirements of Standard 90.1-2013 indicates national primary 
energy savings of approximately 8.5 percent of commercial building 
energy consumption (in comparison to Standard 90.1-2010). Site energy 
savings over Standard 90.1-2010 are estimated to be approximately 7.6 
percent. Using national average fuel prices for electricity and natural 
gas, DOE also estimates a reduction in energy expenditures of 8.7 
percent compared to Standard 90.1-2010.
    Table IV.3 and Table IV.4 show the energy use and associated 
savings resulting from Standard 90.1-2013 by building type and on an 
aggregated national basis. Further details on the quantitative analysis 
can be found in the full technical support document (TSD) \8\ available

V. Preliminary Determination Statement

    Review and evaluation of the 2010 and 2013 editions of Standard 
90.1 indicate that there are significant differences between the two 
editions. Qualitative analysis of the updated Standard reveals that a 
majority of the addenda are anticipated to result in significant energy 
savings. In addition, quantitative analysis of the Standard indicates 
source and site energy savings of 8.5 percent and 7.6 percent, 
respectively. DOE has rendered the preliminary conclusion that Standard 
90.1-2013 will improve energy efficiency in commercial buildings, and, 
therefore, should receive an affirmative determination under Section 
304(b) of ECPA.

VI. State Certification

    If today's determination is finalized, each State would be required 
to review and update, as necessary, the provisions of its commercial 
building energy code to meet or exceed the provisions of the 2013 
edition of Standard 90.1. (42 U.S.C. 6833(b)(2)(B)(i)) This action 
would be required not later than 2 years from the date of the final 
determination notice, unless an extension is provided.

State Review and Update

    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 2013 edition of Standard 90.1. States may base their certifications 
on reasonable actions by units of general-purpose local government. 
Each such State must review the information obtained from the local 
governments, and gather any additional data and testimony in preparing 
its own certification.
    The applicability of any State revisions to new or existing 
buildings would be governed by the State building codes. States should 
be aware that the DOE considers high-rise (greater than three stories) 
multi-family residential buildings as commercial buildings for

[[Page 27792]]

energy code purposes, as is consistent with the scope of Standard 90.1. 
Consequently, commercial buildings, for the purposes of certification, 
would include high-rise multi-family residential buildings, hotels, 
motels, and other transient residential building types of any height.

State Certification Statements

    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 90.1-2013. (42 U.S.C. 
6833(b)) The certification must include a demonstration that the 
provisions of the State's commercial building energy code regarding 
energy efficiency meets or exceeds Standard 90.1-2013. If a State 
intends to certify that its commercial building energy code already 
meets or exceeds the requirements of Standard 90.1-2013, the State 
should provide an explanation of the basis for this certification 
(e.g., Standard 90.1-2013 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 (e.g., director of the State 
energy office, State code commission, utility commission, or equivalent 
State agency having primary responsibility for commercial building 
energy codes), would provide the certification to the Secretary. Such a 
designated State official would also provide the certifications 
regarding the codes of units of general purpose local government based 
on information provided by responsible local officials.
    The DOE Building Energy Codes Program tracks and reports State code 
adoption and certifications.\9\ 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 
code (i.e., ASHRAE Standard 90.1-2013). DOE 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 does provide incentive funding (e.g., grants) 
to these States through the State Energy Program. 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 above, or may be submitted to 
BuildingEnergyCodes@ee.doe.gov.

VII. 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 
policies available on the Office of General Counsel Web site.\10\

    DOE has reviewed today's preliminary determination under the 
provisions of the Regulatory Flexibility Act and the procedures and 
policies published in February 2003. Once DOE finalizes this 
preliminary 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 
preliminary 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 preliminary 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 
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 2 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

[[Page 27793]]

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.

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. DOE has 
reviewed the statutory authority, and 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(b) of ECPA, DOE is statutorily required to 
determine whether the most recent edition of Standard 90.1 would 
improve the level of energy efficiency in commercial buildings as 
compared to the previous edition. 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 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, 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 preliminary 
determination was not required.
    However, DOE notes that State and local governments were invited to 
participate in the development Standard 90.1-2013. The ASHRAE Standard 
is developed in a national, ANSI-approved consensus process open to the 
public, and in which State and local governments may participate, along 
with the general public. The updated Standard is the product of a 
series of amendments to the prior edition of the Standard, with each 
addendum made available for public review with any interested party 
having the ability to submit comments. Comments on the addendum are 
received, reviewed, and resolved through an established process 
commonly utilized in generating industry consensus standards. Members 
of the Standard 90.1 project committee have included representatives of 
State and local governments. DOE believes that this process has given 
State and local jurisdictions extensive opportunity to comment and 
express any concerns on Standard 90.1-2013, the subject of this 
preliminary determination.
    On issuance of a final determination that Standard 90.1-2013 would 
improve the energy efficiency of commercial buildings, ECPA requires 
each State 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 90.1-2013. 
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 90.1-2013 or develop their own code that meets or exceeds 
Standard 90.1-2013.

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. Documentation supporting this 
review is contained in Appendix D of the full Quantitative Analysis 
technical support document (TSD) \11\ available at https://

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 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.

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).

Notification of Special Requests

    In preparation for future technical assistance activities, DOE is 
interested in public comments and additional information regarding the 
costs and benefits associated with the adoption and use of Standard 
90.1, as a whole, and appropriate methodologies for assessing costs, 
benefits and cost-effectiveness. As discussed in the Methodology 
section of this document, DOE is 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)) As 
part of its technical assistance role, DOE previously established a 
methodology by which it evaluates the cost effectiveness of energy 
codes (78 FR 47677). In the coming months, DOE intends to publish a 
request for information (RFI) to update this methodology, and to ensure 
DOE activities continue to remain in alignment with the national model 
code development processes. In particular, DOE will be interested in 
public comments identifying available and adequate sources of data to 
support national and State-level cost analysis, such as localized cost 
data and construction practices. DOE expects to use such input in 
updating its own cost-effectiveness methodology, and in applying this 
methodology through technical assistance functions, including the 
evaluation of published model energy codes, as well as proposed 
changes.

    Issued in Washington, DC, on May 8, 2014.
