PRINTED IN THE U.S.A.2015 INTERNATIONAL ENERGY CONSERVATION CODEiiiPREFACEIntroductionInternationally, code officials recognize the need for a modern, up-to-date energy conservationcode addressing the design of energy-efficien
6、t building envelopes and installation of energy-effi-cient mechanical, lighting and power systems through requirements emphasizing performance. TheInternational Energy Conservation Code, in this 2015 edition, is designed to meet these needsthrough model code regulations that will result in the optim
7、al utilization of fossil fuel and nonde-pletable resources in all communities, large and small.This code contains separate provisions for commercial buildings and for low-rise residentialbuildings (3 stories or less in height above grade). Each set of provisions, IECCCommercial Provi-sions and IECCR
8、esidential Provisions, is separately applied to buildings within their respectivescopes. Each set of provisions is to be treated separately. Each contains a Scope and Administrationchapter, a Definitions chapter, a General Requirements chapter, a chapter containing energy effi-ciency requirements an
9、d existing building provisions applicable to buildings within its scope.This comprehensive energy conservation code establishes minimum regulations for energy-effi-cient buildings using prescriptive and performance-related provisions. It is founded on broad-basedprinciples that make possible the use
10、 of new materials and new energy-efficient designs. This 2015edition is fully compatible with all of the International Codes(I-Codes) published by the Interna-tional Code Council (ICC), including: the International Building Code, International Existing Build-ing Code, International Fire Code, Intern
11、ational Fuel Gas Code, International Green ConstructionCode, International Mechanical Code, ICC Performance Code, International Plumbing Code,International Private Sewage Disposal Code, International Property Maintenance Code, Interna-tional Residential Code, International Swimming Pool and Spa Code
12、, International Wildland-Urban Interface Codeand International Zoning Code.The International Energy Conservation Code provisions provide many benefits, among which isthe model code development process that offers an international forum for energy professionals todiscuss performance and prescriptive
13、code requirements. This forum provides an excellent arena todebate proposed revisions. This model code also encourages international consistency in the appli-cation of provisions.DevelopmentThe first edition of the International Energy Conservation Code (1998) was based on the 1995 edi-tion of the M
14、odel Energy Code promulgated by the Council of American Building Officials (CABO)and included changes approved through the CABO Code Development Procedures through 1997.CABO assigned all rights and responsibilities to the International Code Council and its three statu-tory members at that time, incl
15、uding Building Officials and Code Administrators International, Inc.(BOCA), International Conference of Building Officials (ICBO) and Southern Building Code CongressInternational (SBCCI). This 2015 edition presents the code as originally issued, with changesreflected in the 2000 through 2012 edition
16、s and with changes approved through the ICC CodeDevelopment Process through 2014. A new edition such as this is promulgated every 3 years.This code is founded on principles intended to establish provisions consistent with the scope ofan energy conservation code that adequately conserves energy; prov
17、isions that do not unnecessar-ily increase construction costs; provisions that do not restrict the use of new materials, products ormethods of construction; and provisions that do not give preferential treatment to particular typesor classes of materials, products or methods of construction.iv 2015
18、INTERNATIONAL ENERGY CONSERVATION CODEAdoptionThe International Code Council maintains a copyright in all of its codes and standards. Maintainingcopyright allows the ICC to fund its mission through sales of books, in both print and electronic for-mats. The International Energy Conservation Code is d
19、esigned for adoption and use by jurisdictionsthat recognize and acknowledge the ICCs copyright in the code, and further acknowledge the sub-stantial shared value of the public/private partnership for code development between jurisdictionsand the ICC.The ICC also recognizes the need for jurisdictions
20、 to make laws available to the public. All ICCcodes and ICC standards, along with the laws of many jurisdictions, are available for free in a non-downloadable form on the ICCs website. Jurisdictions should contact the ICC at adoptionsicc-safe.org to learn how to adopt and distribute laws based on th
21、e International Energy ConservationCode in a manner that provides necessary access, while maintaining the ICCs copyright.MaintenanceThe International Energy Conservation Code is kept up to date through the review of proposedchanges submitted by code enforcing officials, industry representatives, des
22、ign professionals andother interested parties. Proposed changes are carefully considered through an open code develop-ment process in which all interested and affected parties may participate.The contents of this work are subject to change through both the code development cycles andthe governmental
23、 body that enacts the code into law. For more information regarding the codedevelopment process, contact the Codes and Standards Development Department of the Interna-tional Code Council. While the development procedure of the International Energy Conservation Code assures thehighest degree of care,
24、 the ICC, its members and those participating in the development of this codedo not accept any liability resulting from compliance or noncompliance with the provisions becausethe ICC does not have the power or authority to police or enforce compliance with the contents ofthis code. Only the governme
25、ntal body that enacts the code into law has such authority.Code Development Committee Responsibilities(Letter Designations in Front of Section Numbers)In each code development cycle, proposed changes to the code are considered at the CommitteeAction Hearings by the applicable International Code Deve
26、lopment Committee. The IECCCommer-cial Provisions (sections designated with a “C” prior to the section number) are primarily maintainedby the Commercial Energy Code Development Committee. The IECCResidential Provisions (sec-tions designated with an “R” prior to the section number) are maintained by
27、the Residential EnergyCode Development Committee. This is designated in the chapter headings by a CE and RE,respectively. Maintenance responsibilities for the IECC are designated as follows:CE = Commercial Energy Code Development CommitteeRE = Residential Energy Code Development CommitteeFor the dev
28、elopment of the 2018 edition of the I-Codes, there will be three groups of code devel-opment committees and they will meet in separate years. Note that these are tentative groupings.2015 INTERNATIONAL ENERGY CONSERVATION CODEvNote: Proposed changes to the ICC Performance Code will be heard by the co

Th
39、e IECC addresses energy conservation require-ments for all aspects of energy uses in both commercial and residential construction, includingheating and ventilating, lighting, water heating, and power usage for appliances and building sys-tems. The IECC is a design document. For example, before one c
40、onstructs a building, the designer mustdetermine the minimum insulation R-values and fenestration U-factors for the building exteriorenvelope. Depending on whether the building is for residential use or for commercial use, the IECCsets forth minimum requirements for exterior envelope insulation, win
41、dow and door U-factors andSHGC ratings, duct insulation, lighting and power efficiency, and water distribution insulation.Arrangement and Format of the 2015 IECC The IECC contains two separate sets of provisionsone for commercial buildings and one for resi-dential buildings. Each set of provisions i
42、s applied separately to buildings within their scope. TheIECCCommercial Provisions apply to all buildings except for residential buildings three stories orless in height. The IECCResidential Provisions apply to detached one- and two-family dwellingsand multiple single-family dwellings as well as Gro
43、up R-2, R-3 and R-4 buildings three stories or lessin height. These scopes are based on the definitions of “Commercial building” and “Residentialbuilding,” respectively, in Chapter 2 of each set of provisions. Note that the IECCCommercial Pro-visions therefore contain provisions for residential buil
44、dings five stories or greater in height. Eachset of provisions is divided into five different parts: The following is a chapter-by-chapter synopsis of the scope and intent of the provisions of theInternational Energy Conservation Code and applies to both the commercial and residential energyprovisio
45、ns:Chapter 1 Scope and Administration. This chapter contains provisions for the application,enforcement and administration of subsequent requirements of the code. In addition to establish-ing the scope of the code, Chapter 1 identifies which buildings and structures come under its pur-view. Chapter
46、1 is largely concerned with maintaining “due process of law” in enforcing the energyconservation criteria contained in the body of this code. Only through careful observation of theadministrative provisions can the code official reasonably expect to demonstrate that “equal pro-tection under the law”
47、 has been provided.

Chapter 2 is the repository of th
48、e definitions of terms used in the body ofthe code. Codes are technical documents and every word, term and punctuation mark can impactthe meaning of the code text and the intended results. The code often uses terms that have aunique meaning in the code and the code meaning can differ substantially f
49、rom the ordinarilyunderstood meaning of the term as used outside of the code.The terms defined in Chapter 2 are deemed to be of prime importance in establishing the mean-ing and intent of the code text. The user of the code should be familiar with and consult this chapterbecause the definitions are essential to the correct interpretation of the code and the user may notbe aware that a term is defined.Additional definitions regarding climate zones are fo
