The International Energy Conservation Code", in this 2012 edition, is designed to meet these needs through model code regulations that will result in the optimal 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 residential buildings (3 stories or less in height above grade.) Each set of provisions in this code—IECC-Com- mercial Provisions and IECC—Residential Provisions are separately applied to buildings within their respective scopes. Each set of provisions are to be treated separately; they each contain a Scope and Administration chapter, a Definitions chapter, a General Requirements chapter, and a chapter containing energy efficiency requirements applicable to buildings within their 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 -based principles that make possible the use of new materials and new energy efficient designs. This 2012 edition 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" International Fuel Gas Code°, International Green Construction Code TM (to be available March 2012), International Mechanical Code', ICC Performance Code°, International Plumbing Code°, International Private Sewage Disposal Code°, International Property Maintenance Code°, International Residential Code" International Swimming Pool and Spa Code TM (to be available March 2012), International Wildland-Urban Interface Code' and International Zon- ing Code The International Energy Conservation Code provisions provide many benefits, among which is the model code development process that offers an international forum for energy professionals to discuss performance and prescriptive code requirements. This forum provides an excellent arena to debate proposed revisions. This model code also encourages international consistency in the appli- cation of provisions. The first edition of the International Energy Conservation Code (1998) was based on the 1995 edi- tion of the Model 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, including Building Officials and Code Administrators International, Inc. (BOCA), International Conference of Building Officials (ICBO) and Southern Building Code Congress International (SBCCI). This 2012 edition presents the code as originally issued, with changes reflected in the 2000, 2003, 2006 and 2009 editions and further changes approved through the ICC Code Development Process through 2010. A new edition such as this is promulgated every three years. 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. 2012 INTERNATIONAL ENERGY CONSERVATION CODE® III I " ' Copy,ght @ zoI I ICC ALL RIGHTS RESERVED Awsed by ().(-)O,d,,Nombsx 100760189 oc Sep so.2.o19 Oi 18 PM(PDT) p—Potto l»eAge mt,oUICC No FYUP ep,oddtoa oAYUP, ( ,,Fodw.m,,bymytl,dpury.o,ANb,to,au o,sd Single—®Iy opymg Podortuodmgplokb,Ad ANY UNAUTHORIZED REPRODUCTION REDISTRIBUTION IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT, AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Adoption Maintenance The International Energy Conservation Code is available for adoption and use by jurisdictions inter- nationally. Its use within a governmental jurisdiction is intended to be accomplished through adop- tion by reference in accordance with proceedings establishing the jurisdiction's laws. At the time of adoption, jurisdictions should insert the appropriate information in provisions requiring specific local information, such as the name of the adoptingjurisdiction. These locations are shown in brack- eted words in small capital letters in the code and in the sample ordinance. The sample adoption ordinance on page ix addresses several key elements of a code adoption ordinance, including the information required for insertion into the code text. 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 contents of this work are subject to change both through the Code Development Cycles and the governmental body that enacts the code into law. For more information regarding the code development 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 the highest degree of care, ICC, its members and those participating in the development of this code do not accept any liability resulting from compliance or noncompliance with the provisions because ICC and its members do not have the power or authority to police or enforce compliance with the con- tents of this code. Only the governmental 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 Code Devel- opment Hearings by the applicable International Code Development Committee. The IECC—Com- mercial Provisions (sections designated with a "C" prior to the section number) are primarily maintained by the Commercial Energy Code Development Committee. The IECC—Residential Provi- sions (sections designated with an "R" prior to the section number) are maintained by the Residen- tial Energy Code Development Committee. This is designated in the chapter headings by a [CE] and [RE], respectively. Proposed changes to a code section or defined term, other than those designated by [CE] or [RE], that has a number beginning with a letter in brackets are considered by a different code development committee. For example, proposed changes to code sections or defined terms that have [M] in front of them are considered by the International Mechanical Code Development Committee. Maintenance responsibilities for the IECC are designated as follows: [CE] = Commercial Energy Code Development Committee [M] = International Mechanical Code Development Committee [RE] = Residential Energy Code Development Committee iv 2012 INTERNATIONAL ENERGY CONSERVATION CODE" " ' CoTy,ght @ ON I ICC ALL RIGHTS RESERVED A-P—d by ().(-)O,d,,Nombsx 100760189 oc Sep SO,2019 Oi 18 PM(PDT) p—Potto l»eAge mt,oUICC No FYUP ep,odw.noa oAYUP, S I ( ,Fod,Yo,,bymytl,dputy,o,ANb�to,au o,sd Single —oPIA PTymg andortuodmg FoIRbad ANY UNAUTHORIZED REPRODUCTION REDISTRIBUTION IS A VIOLATION OF THE ,EDERAL COPYRIGHT 11 AND THE LICENSE AGREEMENT, AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Marginal Markings Note that, for the development of the 2015 edition of the I -Codes, there will be two groups of code development committees and they will meet in separate years. The groupings are as follows: Group A Codes (Heard in 2012, Code Change Proposals Deadline: January 3, 2012) Group B Codes (Heard in 2013, Code Change Proposals Deadline: January 3, 2013) International Building Code Administrative Provisions (Chapter 1 all codes except the IECC, IRC and ICCPC, administrative updates to cur- rently referenced standards, and designated definitions) International Fuel Gas Code International Energy Conservation Code International Mechanical Code International Existing Building Code International Plumbing Code International Fire Code International Private Sewage Disposal Code International Green Construction Code ICC Performance Code International Property Maintenance Code International Residential Code International Swimming Pool and Spa Code International Wildland-Urban Interface Code International Zoning Code Code change proposals submitted for code sections that have a letter designation in front of them will be heard by the respective committee responsible for such code sections. Because differ- ent committees will meet in different years, it is possible that some proposals for this code will be heard by a committee in a different year than the year in which the primary committees for this code meets. For example, the definition of the term "Energy Recovery Ventilation System" for the IECC— Commercial Provisions (page C-8) is the responsibility of the International Mechanical Code Devel- opment Committee, which is part of the Group A code hearings. Therefore, any proposed changes to this defined term will need to be submitted by the deadline for the Group A codes, so that the International Mechanical Code Development Committee can consider that proposed change during the 2012 Code Change Cycle. It is very important that anyone submitting code change proposals understand which code devel- opment committee is responsible for the section of the code that is the subject of the code change proposal. For further information on the code development committee responsibilities, please visit the ICC web site at www.iccsafe.org/scoping. Solid vertical lines in the margins within the body of the code indicate a technical change from the requirements of the 2009 edition. Deletion indicators in the form of an arrow (Ml�) 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. A single asterisk [*] placed in the margin indicates that text or a table has been relocated within the code.

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 2012 IECC The IECC contains two separate sets of provisions —one for commercial buildings and one for resi- dential buildings. Each set of provisions are applied separately to buildings within their scope. The IECC—Commercial Provisions apply to all buildings except for residential buildings 3 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 build- ing," respectively, in Chapter 2 of each set of provisions. Note that the IECC—Commercial Provisions therefore contain provisions for residential buildings 4 stories or greater in height. Each set of provi- sions is divided into 4 different parts: Chapters Subjects 1-2 Administration and definitions 3 Climate zones and general materials requirements 4 Energy efficiency requirements 5 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 Administration. This chapter contains provisions for the application, enforcement and administration of subsequent requirements of the code. In addition to establishing the scope of the code, Chapter 1 identifies which buildings and structures come under its purview. Chapter 1 is largely concerned with maintaining "due process of law" in enforcing the energy conservation crite- ria contained in the body of the code. Only through careful observation of the administrative provi- sions can the building official reasonably expect to demonstrate that "equal protection under the law" has been provided. Chapter 2 Definitions. All terms that are defined in the code are listed alphabetically in Chapter 2. While a defined term may be used in one chapter or another, the meaning provided in Chapter 2 is applicable throughout the code. 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 wherever it appears in the code. 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 pre- scribed 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. 2012 INTERNATIONAL ENERGY CONSERVATION CODE" vii I i i i CoTy,ght @ zoI I ICC ALL RIGHTS RESERVED Awsedby().(-)O,d,,Nombsx1oovco189 oc SIP so.2.o19 Oi 18 PM (PDT) p—Potto l»eAge mt,oUICC No FYUP ep,oddtoaoAYUP, ( ,,Fodw.m,,bymytl,dpury.o,ANb,to,au o,sd Single—®Iy opymg Podortuodmgplokb,Ad ANY UNAUTHORIZED REPRODUCTION REDISTRIBUTION IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT, AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER 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 requirement (U-factors) as well as provisions that affect the mechanical systems based upon the cli- mate 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 requirements or elimination of 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. Resi- dential buildings, townhouses and garden apartments three stories or less in height are covered in the IECC—Residential Provisions. 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. 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. 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 building 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. Chapter 5 Referenced Standards. The code contains numerous references to standards that are used to regulate materials and methods of construction. Chapter 5 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 5 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 upon 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. viii 2012 INTERNATIONAL ENERGY CONSERVATION CODE" Copy,ghtOo ON I ICC ALL RIGHTS RESERVED Awsed by ().(-)O,d,,Nombsx 100760189 oc Sep SO,2019 Oi 18 PM (PDT) p—Potto l»eAge mt,oUICC No FYUP ep,odw.noa oAYUP, iff MT, I ( il i [IFodUt.. byzoyUb,dparty.oPAembmoo Uoosd Single—oPIA PTymg PodortxodmgFokbad ANY UNAUTHORIZED REPRODUCTION REDISTRIBUTION IS A VIOLATION OF THE ,ED REAL COPYRIGHT 11 AND THE LICENSE AGREEMENT, AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER LEGISLATION The International Codes are designed and promulgated to be adopted by reference by legislative action.

A lamp base that requires a screw -in -type lamp, such as a compact -fluorescent, incandes- cent, or tungsten -halogen bulb. 2012 INTERNATIONAL ENERGY CONSERVATION CODE" C-9 I " ' Copy,gbtOO?.o„ ICC ALL RIGHTS RESERVED A-P—dby().(-)O,d,,Nombsxlow6ole9 oc SIP V,2o19 oa.le PM(PDT)p—Pot to IL eAgemt,oUICC No FYUPep,oddtoaoAYUP, (,,Fod,Yo¢tbymytl,dputy,o,ANb,to,au o,sd Single —oPIA opymg PodortuodmgFokbad ANY VNAVTHORIVED REPRODUCTION REDISTRIBUTION IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT, AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER DEFINITIONS SERVICE WATER HEATING. Supply of hot water for pur- poses other than comfort heating. SKYLIGHT. Glass or other transparent or translucent glazing material installed at a slope of less than 60 degrees (1.05 rad) from horizontal. Glazing material in skylights, including unit skylights, solariums, sunrooms, roofs and sloped walls is included in this definition. [B] SLEEPING UNIT. A room or space in which people sleep, which can also include permanent provisions for living, eating, and either sanitation or kitchen facilities but not both. Such rooms and spaces that are also part of a dwelling unit are not sleeping units. SOLAR HEAT GAIN COEFFICIENT (SHGC). The ratio of the solar heat gain entering the space through the fenestration assembly to the incident solar radiation. Solar heat gain includes directly transmitted solar heat and absorbed solar radiation which is then reradiated, conducted or convected into the space. STANDARD REFERENCE DESIGN. A version of the pro- posed design that meets the minimum requirements of this code and is used to determine the maximum annual energy use requirement for compliance based on total building perfor- mance. STOREFRONT. A nonresidential system of doors and win- dows mulled as a composite fenestration structure that has been designed to resist heavy use. Storefront systems include, but are not limited to, exterior fenestration systems that span from the floor level or above to the ceiling of the same story on commer- cial buildings, with or without mulled windows and doors. SUNROOM. A one-story structure attached to a dwelling with a glazing area in excess of 40 percent of the gross area of the structure's exterior walls and roof. THERMAL ISOLATION. Physical and space conditioning separation from conditioned space(s). The conditioned space(s) shall be controlled as separate zones for heating and cooling or conditioned by separate equipment. THERMOSTAT. An automatic control device used to main- tain temperature at a fixed or adjustable set point. U-FACTOR (THERMAL TRANSMITTANCE). The coeffi- cient of heat transmission (air to air) through a building compo- nent or assembly, equal to the time rate of heat flow per unit area and unit temperature difference between the warm side and cold side air films (Btu/h ft' °F) [W/(m' K)]. [M] VENTILATION. The natural or mechanical process of supplying conditioned or unconditioned air to, or removing such air from, any space. [M] VENTILATION AIR. That portion of supply air that comes from outside (outdoors) plus any recirculated air that has been treated to maintain the desired quality of air within a desig- nated space. VISIBLE TRANSMITTANCE [VT]. The ratio of visible light entering the space through the fenestration product assembly to the incident visible light, Visible Transmittance, includes the effects of glazing material and frame and is expressed as a number between 0 and 1. ZONE. A space or group of spaces within a building with heat- ing or cooling requirements that are sufficiently similar so that desired conditions can be maintained throughout using a single controlling device.

Design loads shall be determined in accordance with the procedures described in ANSI/ASHRAE/ACCA Standard 183. The design loads shall account for the building envelope, light- ing, ventilation and occupancy loads based on the project design. Heating and cooling loads shall be adjusted to account for load reductions that are achieved where energy recovery systems are utilized in the HVAC system in accordance with the ASHRAE HVAC Systems and Equip- ment Handbook Alternatively, design loads shall be deter- mined by an approved equivalent computation procedure, using the design parameters specified in Chapter 3. C403.2.2 Equipment and system sizing. The output capac- ity of heating and cooling equipment and systems shall not exceed the loads calculated in accordance with Section C403.2.1. A single piece of equipment providing both heating and cooling shall satisfy this provision for one function with the capacity for the other function as small as possible, within available equipment options. Exceptions: 1. Required standby equipment and systems pro- vided with controls and devices that allow such systems or equipment to operate automatically only when the primary equipment is not operating. 2. Multiple units of the same equipment type with combined capacities exceeding the design load and provided with controls that have the capability to sequence the operation of each unit based on load. C403.2.3 HVAC equipment performance requirements. Equipment shall meet the minimum efficiency requirements of Tables C403.2.3(1), C403.2.3(2), C403.2.3(3), C403.2.3(4), C403.2.3(5), C403.2.3(6), C403.2.3(7) and C403.2.3(8) when tested and rated in accordance with the applicable test procedure. Plate -type liquid -to -liquid heat exchangers shall meet the minimum requirements of Table C403.2.3(9). The efficiency shall be verified through certi- fication under an approved certification program or, if no certification program exists, the equipment efficiency rat- ings shall be supported by data furnished by the manufac- turer. Where multiple rating conditions or performance requirements are provided, the equipment shall satisfy all stated requirements. Where components, such as indoor or outdoor coils, from different manufacturers are used, calcu- lations and supporting data shall be furnished by the designer that demonstrates that the combined efficiency of the specified components meets the requirements herein. C403.2.3.1 Water-cooled centrifugal chilling pack- ages. Equipment not designed for operation at AHRI Standard 550/590 test conditions of 44°F (7°C) leaving chilled -water temperature and 85°F (29°C) entering con- denser water temperature with 3 gpm/ton (0.054 I/s • kW) condenser water flow shall have maximum full -load kW/ ton and NPL Vratings adjusted using Equations C4-3 and C4-4. Adjusted minimum full -load COP ratings — (Full -load COP from Table 6.8.1C of AHRI Standard 550/590) x K i (Equation C4-3) Adjusted minimum NPLV rating — (IPLV from Table 6.8.1 C of AHRI Standard 550/590) x K i (Equation C44) where: Kd, — Ax13 A — 0.0000015318 x (LIFT)4-0.000202076 x (LIFT)' + 0.0101800 x (LIFT)'- 0.264958 x LIFT + 3.930196 B — 0.0027 x LI."P (°C) + 0.982 LIFT — LgCFod—LgEvap L 9Cod — Full -load condenser leaving water temp- erature CQ L„gv'ap — Full -load leaving evaporator temperature (A C) SI units shall be used in the K i equation. The adjusted full -load and NPL V values shall only be applicable for centrifugal chillers meeting all of the following full -load design ranges: 1. The leaving evaporator fluid temperature is not less than 36°F (2.2°C). 2. The leaving condenser fluid temperature is not greater than 115°F (46.1°C). 3. LIFT is not less than MAT (11.1 °C) and not greater than 80°F (44.4°C).

SERVICE WATER HEATING. Supply of hot water for pur- poses other than comfort heating. SKYLIGHT. Glass or other transparent or translucent glazing material installed at a slope of less than 60 degrees (1.05 rad) from horizontal. Glazing material in skylights, including unit skylights, solariums, sunrooms, roofs and sloped walls is included in this definition. SOLAR HEAT GAIN COEFFICIENT (SHGC). The ratio of the solar heat gain entering the space through the fenestration assembly to the incident solar radiation. Solar heat gain includes directly transmitted solar heat and absorbed solar radiation which is then reradiated, conducted or convected into the space. STANDARD REFERENCE DESIGN. A version of the pro- posed design that meets the minimum requirements of this code and is used to determine the maximum annual energy use requirement for compliance based on total building perfor- mance.

An assembly with a U- factor equal to or less than that specified in Table R402.1.3 shall be permitted as an alternative to the R- value in Table R402.1.1. R402.1.4 Total UA alternative. If the total building ther- mal envelope UA (sum of U-factor times assembly area) is less than or equal to the total UA resulting from using the U-factors in Table R402.1.3 (multiplied by the same assembly area as in the proposed building), the building shall be considered in compliance with Table R402.1.1. The UA calculation shall be done using a method consis- tent with the ASHRAE Handbook of Fundamentals and shall include the thermal bridging effects of framing mate- rials. The SHGC requirements shall be met in addition to UA compliance. R402.2 Specific insulation requirements (Prescriptive). In addition to the requirements of Section R402.1, insulation shall meet the specific requirements of Sections R402.2.1 through R402.2.12. R402.2.1 Ceilings with attic spaces. When Section R402.1.1 would require R-38 in the ceiling, R-30 shall be deemed to satisfy the requirement for R-38 wherever the full height of uncompressed R-30 insulation extends over the wall top plate at the eaves. Similarly, R-38 shall be deemed to satisfy the requirement for R-49 wherever the full height of uncompressed R-38 insulation extends over the wall top plate at the eaves. This reduction shall not apply to the U-factor alternative approach in Section R402.1.3 and the total UA alternative in Section R402.1.4. R402.2.2 Ceilings without attic spaces. Where Section R402.1.1 would require insulation levels above R-30 and the design of the roof/ceiling assembly does not allow suf- ficient space for the required insulation, the minimum required insulation for such roof/ceiling assemblies shall be R-30. This reduction of insulation from the require- ments of Section R402.1.1 shall be limited to 500 square feet (46 m') or 20 percent of the total insulated ceiling area, whichever is less. This reduction shall not apply to the U-factor alternative approach in Section R402.1.3 and the total UA alternative in Section R402.1.4. R402.2.3 Eave baffle. For air permeable insulations in vented attics, a baffle shall be installed adjacent to soffit and eave vents. Baffles shall maintain an opening equal or greater than the size of the vent. The baffle shall extend over the top of the attic insulation. The baffle shall be per- mitted to be any solid material. R402.2.4 Access hatches and doors. Access doors from conditioned spaces to unconditioned spaces (e.g., attics and crawl spaces) shall be weatherstripped and insulated to a level equivalent to the insulation on the surrounding surfaces. Access shall be provided to all equipment that prevents damaging or compressing the insulation. A wood framed or equivalent baffle or retainer is required to be provided when loose fill insulation is installed, the pur- pose of which is to prevent the loose fill insulation from spilling into the living space when the attic access is opened, and to provide a permanent means of maintaining the installed R-value of the loose fill insulation. R402.2.5 Mass walls. Mass walls for the purposes of this chapter shall be considered above -grade walls of concrete block, concrete, insulated concrete form (ICF), masonry cavity, brick (other than brick veneer), earth (adobe, com- pressed earth block, rammed earth) and solid timber/logs. R402.2.6 Steel -frame ceilings, walls, and floors. Steel - frame ceilings, walls, and floors shall meet the insulation requirements of Table R402.2.6 or shall meet the U-factor requirements of Table R402.1.3. The calculation of the U- factor for a steel -frame envelope assembly shall use a series -parallel path calculation method. R402.2.7 Floors. Floor insulation shall be installed to maintain permanent contact with the underside of the sub - floor decking. R402.2.8 Basement walls. Walls associated with condi- tioned basements shall be insulated from the top of the basement wall down to 10 feet (3048 mm) below grade or to the basement floor, whichever is less. Walls associated with unconditioned basements shall meet this requirement unless the floor overhead is insulated in accordance with Sections R402.1.1 and R402.2.7.
