AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Introduction Development PREFACE The International Energy Conservation Code' (IECC°) establishes minimum requirements for energy -efficient buildings using prescriptive and performance -related provisions. It is founded on broad -based principles that make possible the use of new materials and new energy -efficient designs. This 2018 edition is fully compatible with all of the International Codes" (I -Codes) pub- lished by the International Code Council° (ICC°), including the International Building Code', Interna- tional Existing Building Code°, International Fire Code" International Fuel Gas Code" International Green Construction Code®, International Mechanical Code" International Plumbing Code" Interna- tional Private Sewage Disposal Code°, International Property Maintenance Code" International Res- idential Code°, International Swimming Pool and Spa Code , International Wildland-Urban Interface Code', International Zoning Code' and International Code Council Performance Code'. This code contains separate provisions for commercial buildings and for low-rise residential buildings (3 stories or less in height above grade). Each set of provisions, IECC—Commercial Provi- sions and IECC—Residential Provisions, is separately applied to buildings within its respective scope. Each set of provisions is to be treated separately. Each contains a Scope and Administration chapter, a Definitions chapter, a General Requirements chapter, a chapter containing energy efficiency requirements and existing building provisions applicable to buildings within its scope. The I -Codes, including this International Energy Conservation Code, are used in a variety of ways in both the public and private sectors. Most industry professionals are familiar with the I -Codes as the basis of laws and regulations in communities across the U.S. and in other countries. However, the impact of the codes extends well beyond the regulatory arena, as they are used in a variety of nonregulatory settings, including: • Voluntary compliance programs such as those promoting sustainability, energy efficiency and disaster resistance. • The insurance industry, to estimate and manage risk, and as a tool in underwriting and rate decisions. • Certification and credentialing of individuals involved in the fields of building design, con- struction and safety. • Certification of building and construction -related products. • U.S. federal agencies, to guide construction in an array of government -owned properties. • Facilities management. • 'Best practices' benchmarks for designers and builders, including those who are engaged in projects in jurisdictions that do not have a formal regulatory system or a governmental enforcement mechanism. • College, university and professional school textbooks and curricula. • Reference works related to building design and construction. In addition to the codes themselves, the code development process brings together building pro- fessionals on a regular basis. It provides an international forum for discussion and deliberation about building design, construction methods, safety, performance requirements, technological advances and innovative products. This 2018 edition presents the code as originally issued, with changes reflected in the 2000 through 2015 editions and further changes approved through the ICC Code Development Process through 2017. A new edition such as this is promulgated every 3 years. 2018 INTERNATIONAL ENERGY CONSERVATION CODE® I " ' (ATFIght @ 2017 ICC ALL RIGHTS RESERVED Awned by H®Ih¢ Van Dme(Rv dme pooch od om),(Qty of FRmdNmod) O[do, N=b,, *1 008170S8 01 JM 15, m0 oc s AM (PET) Mt,b,mt to ( Lie Ag,, ^®,At, ICC No FLth, TAodomo6m A LO, goodomo-by o,,,O Party o, AxmboemRowsd Mgle—odympyncg mdoNyb,IyogL,oIRbAd ANY UNAUTHORIZED REPRODUCTION OR DISTRIBUTION IS VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIESTHEREUNDER Maintenance This code is founded on principles intended to establish provisions consistent with the scope of an energy conservation code that adequately conserves energy; provisions that do not unnecessar- ily increase construction costs; provisions that do not restrict the use of new materials, products or methods of construction; and provisions that do not give preferential treatment to particular types or classes of materials, products or methods of construction. The International Energy Conservation Code is kept up to date through the review of proposed changes submitted by code enforcement officials, industry representatives, design professionals and other interested parties. Proposed changes are carefully considered through an open code development process in which all interested and affected parties may participate. The ICC Code Development Process reflects principles of openness, transparency, balance, due process and consensus, the principles embodied in OMB Circular A-119, which governs the federal government's use of private -sector standards. The ICC process is open to anyone; there is no cost to participate, and people can participate without travel cost through the ICC's cloud -based app, cdp- Access°. A broad cross section of interests are represented in the ICC Code Development Process. The codes, which are updated regularly, include safeguards that allow for emergency action when required for health and safety reasons. In order to ensure that organizations with a direct and material interest in the codes have a voice in the process, the ICC has developed partnerships with key industry segments that support the ICC's important public safety mission. Some code development committee members were nomi- nated by the following industry partners and approved by the ICC Board: • National Association of Home Builders (NAHB) • National Multifamily Housing Council (NMHC) The code development committees evaluate and make recommendations regarding proposed changes to the codes. Their recommendations are then subject to public comment and council -wide votes. The ICC's governmental members —public safety officials who have no financial or business interest in the outcome —cast the final votes on proposed changes. The contents of this work are subject to change through the code development cycles and by any governmental entity that enacts the code into law. For more information regarding the code devel- opment process, contact the Codes and Standards Development Department of the International Code Council. While the I -Code development procedure is thorough and comprehensive, the ICC, its members and those participating in the development of the codes disclaim any liability resulting from the publication or use of the I -Codes, or from compliance or noncompliance with their provisions. The ICC does not have the power or authority to police or enforce compliance with the contents of this code. 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 Committee Action Hearings by the applicable International Code Development Committee. The IECC—Commer- cial Provisions (sections designated with a "C" prior to the section number) are primarily maintained by the Commercial Energy Code Development Committee. The IECC—Residential Provisions (sec- tions designated with an "R" prior to the section number) are maintained by the Residential Energy Code 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] = International Commercial Energy Conservation Code Development Committee [RE] = International Residential Energy Conservation Code Development Committee IV 2018 INTERNATIONAL ENERGY CONSERVATION CODE® ill ' CopynghtOo2.017 ICC ALL RIGHTS RESERVED A—LDd by H®Ih¢ Van Dme(Rvdme pooch od om),(Qty of FRmdNmod)O[do,N=b,,*1008170S801 JM 15.

Deletion indicators in the form of an arrow (a*) are provided in the margin where an entire section, paragraph, exception or table has been deleted or an item in a list of items or a table has been deleted. Coordination of the International Codes The coordination of technical provisions is one of the strengths of the ICC family of model codes. The codes can be used as a complete set of complementary documents, which will provide users with full integration and coordination of technical provisions. Individual codes can also be used in subsets or as stand-alone documents. To make sure that each individual code is as complete as pos- sible, some technical provisions that are relevant to more than one subject area are duplicated in some of the model codes. This allows users maximum flexibility in their application of the I -Codes. 2O18 INTERNATIONAL ENERGY CONSERVATION CODE® v I " I (AcynghtOo2.017 ICC ALL RIGHTS RESERVED A—LDd by H®Ih¢ Van Dme(RvdrtpOo,da od om),(Qty of FRmdNmod)O[d6N=b,,*1008170S801 JM 15, m0 oc s AM (PET) Mt,b,mt to ( Liam, Agffi,,At, ICC No fwN¢[TAod,Ao,, m ALO, good,Ao-by o,r,O Party o, Axmboema Romsd Mgle—ody oryncg andoNyb,IyogT,oIRbAd ANY UNAUTHORIZED REPRODUCTION OR DISTRIBUTION IS VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT.

Where such words and terms are not italicized, common - use definitions apply. The words and terms selected have code -specific definitions that the user should read carefully to facilitate better understanding of the code. The International Code Council maintains a copyright in all of its codes and standards. Maintaining copyright allows the ICC to fund its mission through sales of books, in both print and electronic for- mats. The ICC welcomes adoption of its codes by jurisdictions that recognize and acknowledge the ICC's copyright in the code, and further acknowledge the substantial shared value of the public/pri- vate partnership for code development between jurisdictions and the ICC. The ICC also recognizes the need for jurisdictions to make laws available to the public. All I -Codes and I -Standards, along with the laws of many jurisdictions, are available for free in a nondownloadable form on the ICC's website. Jurisdictions should contact the ICC at adop- tions@iccsafe.org to learn how to adopt and distribute laws based on the International Energy Conservation Code in a manner that provides necessary access, while maintaining the ICC's copyright. To facilitate adoption, two sections of this code contain blanks for fill-in information that needs to be supplied by the adopting jurisdiction as part of the adoption legislation.

AND SUBJECT TO CIVIL AND CRIMINAL PBNALTIBSTHBRRVNDBR EFFECTIVE USE OF THE INTERNATIONAL ENERGY CONSERVATION CODE The International Energy Conservation Code (IECC) is a model code that regulates minimum energy conservation requirements for new buildings. The IECC addresses energy conservation require- ments for all aspects of energy uses in both commercial and residential construction, including heating and ventilating, lighting, water heating, and power usage for appliances and building sys- tems. The IECC is a design document. For example, before one constructs a building, the designer must determine the minimum insulation R-values and fenestration U-factors for the building exterior envelope. Depending on whether the building is for residential use or for commercial use, the IECC sets forth minimum requirements for exterior envelope insulation, window and door U-factors and SHGC ratings, duct insulation, lighting and power efficiency, and water distribution insulation. Arrangement and Format of the 2018 IECC The IECC contains two separate sets of provisions —one for commercial buildings and one for resi- dential buildings. Each set of provisions is applied separately to buildings within their scope. The IECC—Commercial Provisions apply to all buildings except for residential buildings three stories or less in height. The IECC—Residential Provisions apply to detached one- and two-family dwellings and multiple single-family dwellings as well as Group R-2, R-3 and R-4 buildings three stories or less in height. These scopes are based on the definitions of "Commercial building" and 'Residential building," respectively, in Chapter 2 of each set of provisions. Note that the IECC—Commercial Pro- visions therefore contain provisions for residential buildings four stories or greater in height. Each set of provisions is divided into five different parts: Chapters Subjects 1-2 Administration and definitions 3 Climate zones and general materials requirements 4 Energy efficiency requirements 5 Existing buildings 6 Referenced standards The following is a chapter -by -chapter synopsis of the scope and intent of the provisions of the International Energy Conservation Code and applies to both the commercial and residential energy provisions: 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 1 is largely concerned with maintaining "due process of law" in enforcing the energy conservation criteria contained in the body of this code. Only through careful observation of the administrative provisions can the code official reasonably expect to demonstrate that "equal pro- tection under the law" has been provided. 2018 INTERNATIONAL ENERGY CONSERVATION CODE® vii I i i i CITFIghtOo2.017 ICC ALL RIGHTS RESERVED A—LDd by H®Ih¢ Van Dme(Rv dme pooch od om),(Dty of FRmdNmod)O[do,N=b,,*1008170S801 JM 15.

AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Chapter 2 Definitions. Chapter 2 is the repository of the definitions of terms used in the body of the code. Codes are technical documents and every word, term and punctuation mark can impact the meaning of the code text and the intended results. The code often uses terms that have a unique meaning in the code and the code meaning can differ substantially from the ordinarily understood 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 chapter because the definitions are essential to the correct interpretation of the code and the user may not be aware that a term is defined. Additional definitions regarding climate zones are found in Tables 301.3(1) and (2). These are not listed in Chapter 2. Where understanding of a term's definition is especially key to or necessary for understanding of a particular code provision, the term is shown in italics. This is true only for those terms that have a meaning that is unique to the code. In other words, the generally understood meaning of a term or phrase might not be sufficient or consistent with the meaning prescribed by the code; therefore, it is essential that the code -defined meaning be known. Guidance regarding tense, gender and plurality of defined terms as well as guidance regarding terms not defined in this code is provided. Chapter 3 General Requirements. Chapter 3 specifies the climate zones that will serve to establish the exterior design conditions. In addition, Chapter 3 provides interior design conditions that are used as a basis for assumptions in heating and cooling load calculations, and provides basic material requirements for insulation materials and fenestration materials. Climate has a major impact on the energy use of most buildings. The code establishes many requirements such as wall and roof insulation R-values, window and door thermal transmittance (U-factors) and provisions that affect the mechanical systems based on the climate where the building is located. This chapter contains information that will be used to properly assign the building location into the correct climate zone and is used as the basis for establishing or elimi- nating requirements. Chapter 4 Energy Efficiency. Chapter 4 of each set of provisions contains the technical require- ments for energy efficiency. Commercial Energy Efficiency. Chapter 4 of the IECC—Commercial Provisions contains the energy -efficiency -related requirements for the design and construction of most types of com- mercial buildings and residential buildings greater than three stories in height above grade. This chapter defines requirements for the portions of the building and building systems that impact energy use in new commercial construction and new residential construction greater than three stories in height, and promotes the effective use of energy. In addition to energy conservation requirements for the building envelope, this chapter contains requirements that impact energy efficiency for the HVAC systems, the electrical systems and the plumbing systems. It should be noted, however, that requirements are contained in other codes that have an impact on energy conservation. For instance, requirements for water flow rates are regulated by the International Plumbing Code. Residential Energy Efficiency. Chapter 4 of the IECC—Residential Provisions contains the energy -efficiency -related requirements for the design and construction of residential buildings regulated under this code. It should be noted that the definition of a residential building in this code is unique for this code. In this code, a residential building is a detached one- and two-family dwelling and multiple single-family dwellings as well as R-2, R-3 or R-4 buildings three stories or less in height. All other buildings, including residential buildings greater than three stories in height, are regulated by the energy conservation requirements in the IECC—Commercial Provi- sions. The applicable portions of a residential building must comply with the provisions within this chapter for energy efficiency. This chapter defines requirements for the portions of the building and building systems that impact energy use in new residential construction and pro- motes the effective use of energy. The provisions within the chapter promote energy efficiency in the building envelope, the heating and cooling system and the service water heating system of the building.

AND REJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Chapter 5 Existing Buildings. Chapter 5 of each set of provisions contains the technical energy efficiency requirements for existing buildings. Chapter 5 provisions address the maintenance of buildings in compliance with the code as well as how additions, alterations, repairs and changes of occupancy need to be addressed from the standpoint of energy efficiency. Specific provisions are provided for historic buildings. Chapter 6 Referenced Standards. The code contains numerous references to standards that are used to regulate materials and methods of construction. Chapter 6 contains a comprehensive list of all standards that are referenced in the code. The standards are part of the code to the extent of the reference to the standard. Compliance with the referenced standard is necessary for compli- ance with this code. By providing specifically adopted standards, the construction and installation requirements necessary for compliance with the code can be readily determined. The basis for code compliance is, therefore, established and available on an equal basis to the code official, contractor, designer and owner. Chapter 6 is organized in a manner that makes it easy to locate specific standards. It lists all of the referenced standards, alphabetically, by acronym of the promulgating agency of the standard. Each agency's standards are then listed in either alphabetical or numeric order based on the stan- dard identification. The list also contains the title of the standard; the edition (date) of the standard referenced; any addenda included as part of the ICC adoption; and the section or sections of this code that reference the standard. Abbreviations and Notations The following is a list of common abbreviations and units of measurement used in this code. Some of the abbreviations are for terms defined in Chapter 2. Others are terms used in various tables and text of the code.
