30、d by the Correlating Committee on BuildingCode, and acted on by NFPA at its June Association Technical Meeting held June 912, 2014,in Las Vegas, NV. It was issued by the Standards Council on August 14, 2014, with an effectivedate of September 3, 2014, and supersedes all previous editions.Several Ten

31、tative Interim Amendments (TIAs), indicated by boxed notices at the appro-priate areas within the document, were issued on August 14, 2014. These TIAs implementStandards Council Decision D#14-1 to temporarily withdraw NFPA 1124 and end all NFPAstandards development activities relating to the storage

32、 and retail sales of consumer fire-works. For further information, see Decision D#14-1 at http:/www.nfpa.org/sc2014.An additional TIA was issued on August 14, 2014, for NFPA 5000 addressing a topic otherthan consumer fireworks and is similarly indicated by a boxed notice at the appropriate areawith

34、nt of NFPA 5000The inaugural 2003 edition of NFPA 5000, Building Construction and Safety Code, wasissued in 2002 and was (and still is) the first model building code developed using the fullopen consensusbased procedures accredited by the American National Standards Institute.The first edition marke

35、d the culmination of NFPAs more than 100 years of experience indeveloping voluntary consensus-based codes and standards related to the built environment.From the Life Safety Codeto the Fire Code to the National Electrical Code, sprinkler installation,fuel gas, and myriad other occupancy-specific and

36、 installation standards, NFPA codes andstandards, as well as the codes and standards of other consensus-based standards develop-ment organizations, have addressed almost every aspect of the built environment. The signifi-cant gap in the code regime for the built environment, however, had been the la

37、ck of a modelbuilding code developed using the ANSI procedures.NFPA 5000 endeavors to be responsive to the needs of the enforcement, user, and designcommunities and to be consistent with the other principles of code development to whichNFPA adheres. In addition, the Code is updated in response to, a

38、nd, in some cases, in antici-pation of, emerging technologies or as society looks to code developers to address new haz-ards. Changes to the 2015 edition are consistent with the established goals and objectives thatwork to deliver a safe, usable, and functional building at the end of the design proc

39、ess.In addition to fire, a design hazard that always has been, and always will be, a majorcomponent of any building code, NFPA 5000 provides requirements for other design provi-sions, including natural hazards, accessibility, and building interior environmental issues.Consistent with NFPAs performan

40、ce-based code initiative, NFPA 5000 establishes a clearset of goals and objectives for specifying the expected outcome for occupant safety, buildinguse, and building performance based on the Code requirements. The goals and objectives alsoextend to the expected outcome for a building, its contents,

41、and its mission, when applicable.The goals and objectives are critical in allowing those affected by codes to exercise theperformance-based design approach. In addition, they can be used as a tool for evaluatingequivalency provisions on project-specific jobs or designs.50001NFPA 5000, Building Const

43、il Engineers (ASCE), the Federal Emergency ManagementAgency (FEMA), and the U.S.Access Board, amongothers. The all-hazard design provisions for NFPA 5000 are rounded out with the use of criteria that include elements for arange of hazard and design scenarios, design loads, and natural hazard mitigat

44、ion.Changes to the 2012 edition of NFPA 5000 included the typical updating required for other referenced codes andstandards, including those from other standard-developing organizations. Changes to defined terms in Chapter 3 weremade to allow conformance with NFPAs Glossary of Terms project, whereby

45、 NFPA documents utilize consistent termi-nology when appropriate. Criteria dealing with elevators for occupant evacuation was relocated from Annex E to themain body of the Code in Chapter 11. Work on this concept has continued with the ASME A17/CSA B44 Safety Code forElevators and Escalators Task Gr

46、oups on Use of Elevators by Firefighters and Occupant Egress. These elevator provisionshave matured enough to introduce this concept as a set of mainstream requirements. Related changes derived fromthe same ASME initiative resulted in further modifications to the Chapter 54 requirements for fire ser

47、vice accesselevators. The 2012 Code also recognized use of thermal pins in fire-rated doors; offered further rules and revisionsapplicable to locking arrangements for some egress doors; added a fundamental set of rules for installation of carbonmonoxide alarms; and applied a global revision to recog

48、nize newly updated provisions of the 2010 edition of ASCE/SEI 7, Minimum Design Loads for Buildings and Other Structures.The 2015 edition marks the first time that the various committees involved with NFPA 5000 utilized the tools,enhancements, and procedures (Regulations Governing the Development of

49、 NFPA Standards) associated with the new codedevelopment process. The technical committees and the correlating committee benefitted from the availability of acomplete draft to see the changes in context and to more readily respond to areas needing future revision or changes.This edition has incorporated many changes that have application across the board or only to certain occupanciesand conditions. Numerous changes worked to align NFPA 5000 with the accessibility definitions and scoping provisionsthat are contained in the Department of Justice ABA/ADA criteria (2010 e
