I. Introduction

Section 305 of the Energy Conservation and Production Act (Pub. L. 94-385, ECPA) was amended by Title I of the Energy Policy Act of 1992 (Pub. L. 102-486). Section 305(a)(1) of ECPA requires DOE to establish building energy efficiency standards for all new Federal buildings. (42 U.S.C. 6834(a)(1).) Section 305(a)(1) requires standards for Federal buildings that contain energy efficiency measures that are technologically feasible and economically justified but, at a minimum, require the subject buildings to meet the energy saving and renewable energy specifications in the applicable voluntary consensus energy code specified in section 305(a)(2). (42 U.S.C. 6834(a)(1) and (2).) Until amended by the Energy Policy Act of 2005 (Pub. L. 109-58), section 305(a)(2) set the minimum or baseline standards as the CABO (Council of American Building Officials) Model Energy Code, 1992 (for residential buildings) and ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) Standard 90.1-1989 (for commercial and multi-family high rise residential buildings). Section 305(a)(2)(C) of ECPA requires that DOE consider, in consultation with the Environmental Protection Agency and other Federal agencies, and where appropriate, measures regarding radon and other indoor air pollutants.

Section 306(a)(1) of ECPA provides that each Federal agency must adopt procedures to ensure that new Federal buildings will meet or exceed the Federal building energy efficiency standards established under section 305. (42 U.S.C. 6835(a)(1).) Additionally, section 306(a)(2) extends the requirements for new Federal buildings established under section 305 to buildings under the jurisdiction of the Architect of the Capitol. (42 U.S.C. 6835(a)(2).) Section 306(b) bars the head of a Federal agency from expending Federal funds for the construction of a new Federal building unless the building meets or exceeds the applicable Federal building energy standards established under section 305. (42 U.S.C. 6835(b).)

DOE established Federal building standards under ECPA and initially placed both the commercial and residential standards in Part 435 of Title 10 of the CFR. In a final rule published on October 6, 2000, DOE established new energy efficiency standards for new Federal commercial and multi-family high-rise residential buildings (65 FR 59999). DOE placed the revised Federal commercial and multi-family high-rise Start Printed Page 70277residential building standards in a new 10 CFR Part 434, entitled “Energy Code for New Federal Commercial and Multi-Family High Rise Residential Buildings.” The standards for Federal low-rise residential buildings remain in 10 CFR Part 435.

Section 109 of the Energy Policy Act of 2005 amended section 305 of ECPA. (42 U.S.C. 6835.) Section 109 replaced the minimum standards referenced in section 305(a)(2)(A) with references to updated building codes that are widely used today. For residential buildings, CABO Model Energy Code, 1992, was replaced with the 2004 International Energy Conservation Code (IECC). For commercial and multi-family high rise buildings, ASHRAE Standard 90.1-1989 was replaced with ASHRAE Standard 90.1-2004.

Section 109 of the Energy Policy Act of 2005 also added a new section 305(a)(3)(A) that requires DOE to, by rule, establish revised Federal building energy efficiency performance standards not later than August 8, 2006. (42 U.S.C. 6834(a)(3)(A).) Under the revised standards, new Federal buildings must be designed to achieve energy consumption levels that are at least 30 percent below the updated minimum standards referenced in section 305(a)(2), if life-cycle cost-effective. (42 U.S.C. 6834(a)(3)(A)(i)(I).) Additionally, Federal agencies must apply, if life-cycle cost-effective, sustainable design principles to the siting, design, and construction of all new and replacement buildings. (42 U.S.C. 6834(a)(3)(A)(i)(II).) If water is used to achieve energy efficiency, water conservation technologies shall be applied to the extent that such technologies are life-cycle cost-effective. (42 U.S.C. 6834 (a)(3)(A)(ii).)

II. Discussion of Today's Action

DOE is issuing today's action as an interim final rule. Today's final rule deals solely with the energy efficiency of new Federal buildings, which are public property. Matters that relate to public property are excepted from prior notice and comment requirements. (5 U.S.C. 553(a)(2).) Additionally, the explicitness of the direction provided to DOE for this rule in Section 109 of the Energy Policy Act of 2005 supports issuance of an interim final rule, as a matter of policy. The interim final rule incorporates updated versions of ANSI/ASHRAE/IESNA Standard 90.1-2004, and the IECC standard as directed by statute. The interim final rule also establishes a requirement for new Federal buildings to achieve a level of energy efficiency 30 percent greater than that of the ANSI/ASHRAE/IESNA or IECC levels, as appropriate, when life-cycle cost-effective, again as directed by the statute. DOE also decided that the interim final rule approach offered the best opportunity to achieve the goals of Section 109 of the Energy Policy Act of 2005 as soon as possible.

This interim final rule incorporates by reference ANSI/ASHRAE/IESNA Standard 90.1-2004, Energy Standard for Buildings Except Low-Rise Residential Buildings, and the 2004 International Energy Conservation Code as prescribed by Congress in section 109 of the Energy Policy Act of 2005, into 10 CFR Parts 433 and 435, respectively. Under today's interim final rule, new Federal commercial and multi-family high-rise residential buildings, for which design for construction begins on or after the effective date of today's interim final rule, must be designed to comply with the ASHRAE standard. New Federal low-rise residential buildings, for which design for construction begins on or after the effective date of today's interim final rule, must be designed to comply with the IECC standard.

In addition to complying with the appropriate incorporated standard, a new Federal building must also be designed to achieve an energy consumption level that is at least 30 percent below the level achieved under that standard, if life-cycle cost-effective. Congress expressly specified a minimum performance requirement of a 30 percent improvement, if life-cycle cost effective. Although the statute requires DOE to establish performance standards that are “at least” 30 percent below the levels in the incorporated ASHRAE and IECC standards, the standards that DOE establishes today do not require Federal agencies to consider the life-cycle cost effectiveness of improvements beyond the 30 percent level.

It is DOE's view that had Congress sought to require improvements at a maximum level of life-cycle cost effectiveness, it would have mandated designs to achieve that level and would not have specified the 30 percent minimum. Moreover, absent some direction in the statute, DOE is unable to specify in today's rule an energy consumption level that is greater than 30 percent below the levels achieved under the incorporated standards, but less than the maximum level that would be cost effective. However, as indicated by the words “at least,” Federal agencies are not precluded from designing buildings to achieve greater improvements, and DOE encourages agencies to design new Federal buildings to achieve lower energy consumption levels if life-cycle cost effective.

Further, the experiences of ASHRAE (with the development of their Advanced Energy Design Guides for small office and small retail buildings) and the New Buildings Institute's (NBI) Advanced Buildings program indicate that a savings 30 percent beyond that achieved through the incorporated standards is achievable in most building types with measures that are relatively “standard;” i.e., with measures that are widely available and with which the general industry is familiar. The 30-percent requirement should not necessitate consideration of measures that are limited in availability or with which the general industry is unfamiliar.

If the additional 30 percent savings is not life-cycle cost-effective, an agency must evaluate the cost-effectiveness of alternative designs at successive decrements below 30 percent (e.g., 25 percent, 20 percent, etc.) in order to identify the most energy-efficient design that is life-cycle cost-effective for that building. However, the building must remain compliant with the ANSI/ASHRAE/IESNA Standard 90.1-2004, or IECC standard, as applicable. By requiring consideration of the life-cycle cost effectiveness of improvements if a 30 percent improvement is not life-cycle cost effective, today's final rule ensures that all readily available energy saving measures are considered.

Today's rule also specifies that the methodology defined in 10 CFR part 436, subpart A, be used to establish the life-cycle cost-effectiveness of design measures used to achieve energy consumption levels below the criteria found in the minimum level standards described above. This is done to be consistent with Executive Order 13123, which requires Federal agencies to use this methodology in the design of new Federal buildings, and to respond to the requirements in the Energy Policy Act of 2005 that requirements of the new standards be life-cycle cost-effective. Federal agencies may choose to use one of four methods listed in 10 CFR part 436 to demonstrate life-cycle cost-effectiveness. These methods include lower life-cycle costs, positive net savings, savings-to-investment ratio that is estimated to be greater than one, and an adjusted internal rate of return that is estimated to be greater than the discount rate as listed in OMB Circular Number A-94 “Guidelines and Discount Rates for Benefit-Cost Analysis of Federal Programs.”

In applying this methodology to analysis of new Federal buildings, agencies must estimate the life-cycle Start Printed Page 70278costs and energy consumption of the planned building as designed and an otherwise identical building just meeting the minimum criteria set forth in the applicable baseline ASHRAE or IECC standard. The agencies must try to find a design that reduces energy consumption by a total of 30 percent or more without increasing the planned building's expected life-cycle cost. DOE intends to provide additional guidance and tools to assist Federal agencies in meeting these new building design requirements.

Today's rule does not take a prescriptive approach as to how the 30 percent reduction is to be obtained. The baseline standards contain a limited set of mandatory requirements, such as sealing leaks in the building envelope and air duct systems. Beyond this, there are no restrictions on how the Federal agency achieves cost-effective energy savings. DOE believes that Federal agencies should be given the flexibility necessary to determine the most effective ways to achieve energy savings above that of the incorporated standards, rather than relying on prescriptive requirements that may not be appropriate in all cases.

Today's interim final rule is effective beginning 30 days following Federal Register publication. All new Federal buildings for which design for construction begins on or after that date must comply with the requirements established in this rule. All new Federal buildings for which design for construction has begun prior to that date must comply with the requirements in 10 CFR part 434 or subpart C of part 435, as applicable.

DOE is accepting comments on this interim final rule. The interim final rule will take effect on the date listed above in the DATES heading, and will become part of the CFR. Following close of the comment period, DOE will issue a notice of final rulemaking. If no comments are received, the notice of final rulemaking will adopt as final the interim final rule without change. If comments are received, DOE will respond to issues raised by the comments in the notice of final rulemaking, and either adopt as final the interim final rule without change, or adopt the final rule with change in response to comments.

III. Section 109 of the Energy Policy Act of 2005 Requirements Not Addressed in Today's Rule

Today's rule does not address the requirement that, if life-cycle cost-effective for new Federal buildings, agencies must apply sustainable design principles to the siting, design, and construction of all new and replacement buildings. Today's rule also does not address the requirement that “if water is used to achieve energy efficiency, the revised standards also must require water conservation technologies to be applied to the extent that such technologies are life-cycle cost-effective.” Finally, today's rule does not consider measures with regard to radon and other indoor air pollutants. (42 U.S.C. 6834 (a)(3)(A)(ii)) The developmental process for addressing these complicated issues will take more time and DOE will issue a rulemaking notice containing provisions on these subjects at a later date. DOE is proceeding with the implementation of only the energy efficiency element from the directives of section 305(a) of the Energy Policy Act of 2005 in this interim final rule so that energy efficiency in Federal buildings can be improved as soon as possible.

IV. Reference Resources

The Department has prepared a list of resources to help Federal agencies achieve building energy efficiency levels of at least 30 percent below that of ASHRAE Standard 90.1-2004 or the 2004 IECC. These resources come in many forms—design guidance, case studies and in a variety of media—in printed document or on Web site. Resources are provided in three categories—for all buildings, specifically for commercial and high-rise multi-family residential buildings, and specifically for low-rise residential buildings.

V. Procedural Requirements

A. Review under Executive Order 12866, “Regulatory Planning and Review”

Today's interim final rule is a “significant regulatory action” under section 3(f)(1) of Executive Order 12866, “Regulatory Planning and Review.” 58 FR 51735 (October 4, 1993). Accordingly, today's action was subject to review by the Office of Information and Regulatory Affairs in the Office of Management and Budget (OMB). OMB has completed its review.

B. Review under the Regulatory Flexibility Act

The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires the preparation of an initial regulatory flexibility analysis for any rule that by law must be proposed for public comment, unless the agency certifies that the rule, if promulgated, will not have a significant economic impact on a substantial number of small entities. As required by Executive Order 13272, Proper Consideration of Small Entities in Agency Rulemaking, 67 FR 53461 (August 16, 2002), DOE published procedures and policies on February 19, Start Printed Page 702802003, to ensure that the potential impacts of its rules on small entities are properly considered during the rulemaking process. 68 FR 7990. The Department has made its procedures and policies available on the Office of General Counsel's Web site: http://www.gc.doe.gov.

Today's rule on energy efficiency performance standards for the design and construction of new Federal buildings is not subject to any legal requirement to publish a general notice of proposed rulemaking. Therefore, the Regulatory Flexibility Act does not apply.

C. Review Under the Paperwork Reduction Act of 1995

This rulemaking will impose no new information or record keeping requirements. Accordingly, Office of Management and Budget (OMB) clearance is not required under the Paperwork Reduction Act. (44 U.S.C. 3501 et seq.)

D. Review Under the National Environmental Policy Act of 1969

The Department prepared an Environmental Assessment (EA) (DOE/EA-1463) entitled, Draft Environmental Assessment for Interim Final Rule, 10 CFR Part 433, “Energy Efficiency Standards for New Federal Commercial and Multi-Family High-Rise Residential Buildings,” and 10 CFR Part 435, “Energy Efficiency Standards for New Federal Low-Rise Residential Buildings,” pursuant to the Council on Environmental Quality's (CEQ) Regulations for Implementing the Procedural Provisions of the National Environmental Policy Act (40 CFR Parts 1500-1508), the National Environmental Policy Act of 1969 (NEPA), as amended (42 U.S.C. 4321 et seq.), and DOE's NEPA Implementing Procedures (10 CFR Part 1021).

The EA addresses the possible environmental effects attributable to the implementation of the interim final rule. The only impact would be a decrease in outdoor air pollutants resulting from decreased fossil fuel burning for energy use in Federal buildings.

To identify the potential environmental impacts that may result from implementing the interim final rule on new Federal commercial buildings, DOE compared the interim final rule with a “no-action alternative” of using the current Federal standards—10 CFR Part 434 and 10 CFR Part 435. DOE also compared the interim final rule to the prevailing national voluntary building energy codes, which also are the minimum requirements for the interim final rule. For commercial and high-rise multi-family residential buildings, the American National Standards Institute (ANSI)/American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE)/Illuminating Engineering Society of North America (IESNA) ASHRAE/IESNA Standard 90.1-2004 (ASHRAE 2004) is the minimum requirement for the DOE preferred alternative. For low-rise residential buildings, the International Code Council (ICC) International Energy Conservation Code (IECC) 2004 Supplement Edition (ICC 2004) is the minimum requirement for the DOE preferred alternative. For the purpose of this environmental assessment, DOE also investigated the impact of buildings achieving energy consumption below Standard 90.1-2004 or the 2004 IECC in increments of 10 percent, up to 50 percent.

For low-rise residential buildings, the Federal government is estimated to construct about 2000 housing units annually that would be subject to this rule. Avoided carbon dioxide emissions are estimated at 763 metric tons of carbon in the first year the interim final rule is in effect, if 30 percent savings in energy consumption over the 2004 IECC are achieved. Avoided nitrogen oxide and sulfur dioxide emissions are estimated to be each 4 tons in the first year the rule is in effect.

For commercial and high-rise multi-family residential buildings, the Federal government is estimated to construct 28 million square feet of Federal commercial buildings annually. Federal high-rise residential buildings are rare. Assuming a 30 percent savings in energy consumption over 90.1-2004, avoided carbon dioxide emissions (relative to the existing 10 CFR Part 434) are estimated at 35,800 metric tons of carbon in the first year the interim final rule is in effect, with the savings compounding in future years as more and more Federal construction occurs. Avoided nitrogen oxide emissions are estimated to be 317 tons in the first year the rule is in effect, while the avoided sulfur dioxide emissions are estimated at 625 tons.

DOE will consider all comments received before approving or modifying the EA, as appropriate.

E. Review Under Executive Order 13132, “Federalism”

Executive Order 13132, “Federalism,” 64 FR 43255 (August 4, 1999), imposes certain requirements on agencies formulating and implementing policies or regulations that preempt State law or that have federalism implications. The Executive Order requires agencies to examine the constitutional and statutory authority supporting any action that would limit the policymaking discretion of the States and to carefully assess the necessity for such actions. The Executive Order also requires agencies to have an accountable process to ensure meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications. On March 14, 2000, DOE published a statement of policy describing the intergovernmental consultation process it will follow in the development of such regulations. (65 FR 13735). DOE examined this rule and determined that it does not preempt State law and does not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of Government. No further action is required by Executive Order 13132.

F. Review Under Executive Order 12988, “Civil Justice Reform”

With respect to the review of existing regulations and the promulgation of new regulations, section 3(a) of Executive Order 12988, “Civil Justice Reform,” 61 FR 4729 (February 7, 1996), imposes on Federal agencies the general duty to adhere to the following requirements: (1) Eliminate drafting errors and ambiguity; (2) write regulations to minimize litigation; and (3) provide a clear legal standard for affected conduct, rather than a general standard and promote simplification and burden reduction. Section 3(b) of Executive Order 12988 specifically requires that Executive agencies make every reasonable effort to ensure that the regulation: (1) Clearly specifies the preemptive effect, if any; (2) clearly specifies any effect on existing Federal law or regulation; (3) provides a clear legal standard for affected conduct, while promoting simplification and burden reduction; (4) specifies the retroactive effect, if any; (5) adequately defines key terms; and (6) addresses other important issues affecting clarity and general draftsmanship under any guidelines issued by the Attorney General. Section 3(c) of Executive Order 12988 requires Executive agencies to Start Printed Page 70281review regulations in light of applicable standards in section 3(a) and section 3(b) to determine whether they are met or it is unreasonable to meet one or more of them. DOE has completed the required review and determined that, to the extent permitted by law; this rule meets the relevant standards of Executive Order 12988.

G. Review Under the Unfunded Mandates Reform Act of 1995

Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) (Pub. L. 104-4) requires each Federal agency to assess the effects of Federal regulatory actions on State, local, and tribal governments and the private sector. For a proposed regulatory action likely to result in a rule that may cause the expenditure by State, local, and tribal governments, in the aggregate, or by the private sector of $100 million or more in any one year (adjusted annually for inflation), section 202 of UMRA requires a Federal agency to publish a written statement that estimates the resulting costs, benefits, and other effects on the national economy. (2 U.S.C. 1532(a) and (b)) The UMRA also requires a Federal agency to develop an effective process to permit timely input by elected officers of State, local, and tribal governments on a proposed “significant intergovernmental mandate,” and requires an agency plan for giving notice and opportunity for timely input to potentially affected small governments before establishing any requirements that might significantly or uniquely affect small governments. On March 18, 1997, DOE published a statement of policy on its process for intergovernmental consultation under UMRA (62 FR 12820) (also available at http://www.gc.doe.gov). This interim final rule contains neither an intergovernmental mandate nor a mandate that may result in the expenditure of $100 million or more in any year, so these requirements under the Unfunded Mandates Reform Act do not apply.

H. 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. This interim final rule 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.

I. Review Under Executive Order 12630, “Governmental Actions and Interference With Constitutionally Protected Property Rights”

The Department has determined, under Executive Order 12630, “Governmental Actions and Interference with Constitutionally Protected Property Rights,” 53 FR 8859 (March 18, 1988), that this rule would not result in any takings which might require compensation under the Fifth Amendment to the United States Constitution.

J. Review Under the Treasury and General Government Appropriations Act, 2001

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

K. Review Under Executive Order 13211, “Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use”

Executive Order 13211, “Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use,” 66 FR 28355 (May 22, 2001), requires Federal agencies to prepare and submit to the Office of Information and Regulatory Affairs (OIRA), Office of Management and Budget, 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 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. This interim final rule would not have a significant adverse effect on the supply, distribution, or use of energy and, therefore, is not a significant energy action. Accordingly, DOE has not prepared a Statement of Energy Effects.

VI. Congressional Notification

As required by 5 U.S.C. 801, DOE will report to Congress on the promulgation of this rule prior to its effective date. The report will state that it has been determined that the rule is not a “major rule” as defined by 5 U.S.C. 804(2).

VII. Approval of the Office of the Secretary

The Secretary of Energy has approved publication of today's interim final rule.
