6、HE U.S.A.2015 INTERNATIONAL GREEN CONSTRUCTION CODECOMMENTARY iiiPREFACEThe principal purpose of the Commentary is to provide a basic volume of knowledge and facts relating to building construction as it pertains to the regulations set forth in the 2015 International Green Construction Code(IgCC). T

7、he person who is serious about effectively designing, constructing and regulating buildings and structures will find the Commentary to be a reliable data source and reference for almost all components of the built environment.As a follow-up to the International Green Construction Code, we offer a co

8、mpanion document, the International Green Con-struction CodeCommentary. The basic appeal of the Commentary is that it provides, in a small package and at reasonable cost,thorough coverage of many issues likely to be dealt with when using the International Green Construction Codeand then sup -plement

9、s that coverage with historical and technical background. Reference lists, information sources and bibliographies are also included.Throughout all of this, strenuous effort has been made to keep the vast quantity of material accessible and its method of pre-sentation useful. With a comprehensive yet

10、 concise summary of each section, the Commentary provides a convenient reference for regulations applicable to the construction of buildings and structures. In the chapters that follow, discussions focus on the full meaning and implications of the code text. Recommendations suggest the most effectiv

11、e method of application and the conse-quences of not adhering to the code text. Illustrations are provided to aid understanding; they do not necessarily illustrate the only methods of achieving code compliance.The format of the Commentary includes the full text of each section, table and figure in t

12、he code, followed immediately by the commentary applicable to that text. At the time of printing, the Commentary reflects the most up-to-date text of the 2015 Inter-national Green Construction Code. Each sections narrative includes a statement of its objective and intent, and usually includes a disc

13、ussion about why the requirement commands the conditions set forth. Code text and commentary text are easily distin-guished from each other. All code text is shown as it appears in the International Green Construction Code, and all commentary is indented below the code text and begins with the symbo

14、l . All code figures and tables are reproduced as they appear in the International Green Construction Code. Commentary figures and tables are identified in the text by the word “Commentary,” and each has a full border.Readers should note that the Commentary is to be used in conjunction with the Inte

15、rnational Green Construction Code and not as a substitute for the code. The Commentary is advisory only; the code official alone possesses the authority and responsi-bility for interpreting the code. Please note that, by inclusion of its logo on the cover of this Commentary, the American Society of

27、 following Indexvi 2015 INTERNATIONAL GREEN CONSTRUCTION CODECOMMENTARY 2015 INTERNATIONAL GREEN CONSTRUCTION CODECOMMENTARY 1-1Chapter 1:Scope and AdministrationPART 1SCOPE AND APPLICATIONSECTION 101GENERALA 101.1 Title. These regulations shall be known as the Green Construction Code of NAME OF JUR

28、ISDICTION herein-after referred to as “this code.”The purpose of this section is to identify the adopted regulations by inserting the name of the adopting jurisdiction into the code.A 101.2 General. This code is an overlay document to be used in conjunction with the other codes and standards adopted

29、 by the jurisdiction. This code is not intended to be used as a standalone construction regulation document and permits are not to be issued under this code. This code is not intended to abridge or supersede safety, health or environmen-tal requirements under other applicable codes or ordinances.Adm

30、inistratively, the code is conceived to work as an overlay to other International Codes(I-Codes). It is not intended to be used as a standalone construction regulation document. It depends on other I-Codes to provide administrative requirements for permits, con-struction documents and inspections, a

31、s well as to out-line the duties of the code official. It is not intended to supersede, replace or abridge the safety, health or environmental provisions of other I-Codes or other ordinances that may be in effect in a jurisdiction.A 101.3 Scope. The provisions of this code shall apply to the design,

32、 construction, addition, alteration, change of occu-pancy, relocation, replacement, repair, equipment, building site, maintenance, removal and demolition of every building or structure or any appurtenances connected or attached to such buildings or structures and to the site on which the building is

33、 located. Occupancy classifications shall be deter-mined in accordance with the International Building Code.Exceptions:1. The code shall not apply to items 1.1, 1.2 and 1.3 except where the jurisdiction adopts the jurisdic-tional requirements of Section 302.1, Item 1, for res-idential buildings.1.1.

34、 Detached one- and two-family dwellings and multiple single-family dwellings (town-houses) not more than three stories in height above grade plane with a separate means of egress, their accessory structures, and the site or lot upon which these buildings are located.1.2. Group R-3 residential buildi

35、ngs, their acces-sory structures, and the site or lot upon which these buildings are located.1.3. Group R-2 and R-4 residential buildings four stories or less in height above grade plane, their accessory structures, and the site or lot upon which these buildings are located.2. The code shall not app

36、ly to equipment or systems that are used primarily for industrial or manufactur-ing purposes.3. The code shall not apply to temporary structures approved under Section 3103 of the International Building Code.4. Where ASHRAE 189.1 is selected in accordance with Section 301.1.1, ASHRAE 189.1 shall not

37、 apply to buildings identified in Exceptions 1 through 3.The scope establishes where the regulations con-tained in the code must be followed, whether all or in part. For the code to be applicable, something must happen: a new building must be constructed, an existing building must be modified or an

38、existing structure becomes unsafe and must be brought into compliance. The code is applicable to the following, with excep-tions: New building and building site design and con-struction; Alterations and additions to, and maintenance and demolition of, existing buildings; and Changes of occupancy (se

39、e Chapter 10).Exception 1 exempts the following types of resi-dential buildings and occupancies, except where the jurisdiction indicates in Table 302.1 that it will regu-late these buildings and occupancies in accordance with ICC 700, National Green Building Standard: Low-rise residential buildings

40、that fall under the scope of the International Residential Code(IRC).General CommentsWhen adopted by a jurisdiction, the code is a legal doc-ument that regulates the construction of high-perfor-mance commercial buildings, structures and systems, including existing buildings subject to alterations an

41、d additions, utilizing both traditional and innovative con-struction practices. Provisions for application, enforce-ment and administration are addressed in Chapter 1.SCOPE AND ADMINISTRATION1-2 2015 INTERNATIONAL GREEN CONSTRUCTION CODECOMMENTARY All Group R-3 occupancies. Group R-2 and R-4 residen

42、tial occupancies that are three stories or fewer in height.Occupancy classifications and what qualifies as a temporary structure must be determined in accor-dance with the requirements of the International Building Code(IBC). See the commentary to Section 302.1 for addi-tional requirements related t

43、o the application of ICC 700 to Exception 1. In accordance with Exceptions 2 and 3, respec-tively, the code is not applicable to equipment or sys-tems used for manufacturing or industrial purposes, nor is it applicable to temporary structures that com-ply with IBC Section 3103. Exception 4, as well

44、as Section 301.1.1, allows owners or owners agents to comply with the require-ments of ASHRAE 189.1, Standard for the Design of High-performance, Green Buildings Except Low-rise Residential Buildings, in lieu of the requirements of the code, except that the administrative provisions of Chapter 1 of

45、the code remain in force. The limitations of Exception 1 for residential buildings and occupan-cies apply to buildings designed in accordance with ASHRAE 189.1 as well. See the commentary to Sec-tion 101.3.1 for a similar option for owners and own-ers agents to comply with ICC 700 in lieu of the cod

46、e requirements for certain Group R-2 or R-4 (residen-tial) occupancies that are unaffected by Exception 1. Note that Section 101.3 does not exclude Group R-1 occupancies from the scope of the code in any way; therefore, Group R-1 occupancies of all heights, including those three stories or less in h

47、eight, are regulated by the code. ASHRAE 189.1 cannot be applied to Group R-1 occupancies that are three sto-ries or less in height, or any residential building that is three stories or less in height, as they are not within the scope of ASHRAE 189.1. Also note that ICC 700 is not available as a com

48、pliance option in the code for Group R-1 occupancies.A 101.3.1 Residential construction. The following shall be deemed to comply with this code:1. Group R-2 and R-4 residential buildings five stories or more in height above grade plane, their accessory struc-tures, and the site or lot upon which the

49、se buildings are located that comply with ICC 700, with the minimum energy efficiency category requirements of the Silver performance level or equivalent.2. Group R-2 and R-4 portions of mixed use buildings that comply with ICC 700, with the minimum energy effi-ciency category requirements of the Silver performance level or equivalent. The remainder of
