  2. Agenda 2007-CBC  Big Changes • IBC / CBC Brief History • UL Damper Requirements (2007-CBC) • Smoke Control – Overview of Required Locations • Q&A – as we go

  3. 1994: ICBO, BOCA, & SBCCI form the International Code Council (ICC) to create a single national model building code. 1997: 1st Edition of the International Building Code (IBC) NFPA & ICC Split over consensus process 2003: 3rd Edition of IBC – Widely Adopted 2006: 4th Edition of IBC – Current Edition International Building CodeDevelopment History

  4. IBC - 47 states + Washington, D.C. IRC - 45 states + Washington, D.C. IFC - 41 states + Washington, D.C. IBC Adoption - Nationwide State or Local Adoption

  5. 1997: Final UBC Cycle (1997-CBC) 2000: Readopted 1997-UBC (2001-CBC) 2003: NFPA-5000 adopted in split vote Never published due to recall of Gov. Davis 2005: Rescinded NFPA-5000 & adopted IBC 2006: 2006-IBC modified to meet California requirements 2007: 2007-CBC Published July 1, 2007 January 1, 2008: 2007-CBC Enforcement Statewide California Building CodeRecent History

  9. Walls located on lot lines or that segregate areas into separate buildings. Fire walls run from exterior wall to exterior wall, from foundation to or through the roof, and are self supporting during a fire. All Buildings Fire Dampers OnlyNOEXCEPTIONS No penetrations are allowed on lot lines. (705.11) One of the few allowable penetrations to fire walls is between an anchoring building and a covered mall. (402.7.3) Fire Walls – 716.5.12007 Damper Requirements

  10. Shaft enclosures, exit enclosures, exit passageways, horizontal exits, incidental use areas, occupancy separations, and exterior walls CSFM Regulated Buildings  Fire & Smoke DampersGroupA, E, H, I, L, & R, High-Rise buildings, & others per Section 111. EXCEPTIONS: 1. Tested per ASTM E119 without fire damper  Doesn’t exempt the smoke damper. 2. The fire or smoke damper interferes with 909 smoke control system.

Parking garage shaft separated by 2-hour rated construction. 4. The smoke damper interferes with 909 mechanical smoke control system.

  12. Fire Partitions – 716.5.42007 Damper Requirements Walls separating dwelling units or tenant spaces in covered malls, corridor walls, elevator lobby separations, and exterior walls. CSFM Regulated Buildings  Fire Dampers Only GroupA, E, H, I, L, & R, High-Rise buildings, & others per Section 111. NOEXCEPTIONS Non-CSFM Regulated Buildings  Fire Dampers Only GroupB, F, M, S, & U, except as required in Section 111. EXCEPTIONS: 1. Tenant separations or corridor walls in fully sprinklered buildings with ducts protected as through penetration per Section 712. 2. Tenant partitions in covered malls where walls do not extend to the underside of the floor or roof. 3. 26 ga duct < 100 in2 with no openings to corridor or adjacent rooms, AND The opening is protected with a 12” x 16 ga sleeve with 1-1/2” x 1-1/2” x 16 ga retaining angles AND The annular space between the wall and sleeve is filled with mineral wool bating on all sides.

  13. Corridors – 716.5.4.12007 Damper Requirements Smoke Dampers are required for all fire-resistance rated corridors. • Table 1017.1 defines fire-resistance rating by occupancy. • All CSFM regulated buildings require 1-hour rated corridors. • 707.14.1 Elevator Lobbies Smoke dampers requirements = corridor requirement. CSFM Regulated Buildings  Fire & Smoke Dampers GroupA, E, H, I, L, & R, High-Rise buildings, & others per Section 111. Fire Damper EXCEPTIONS:See Fire Partitions. Smoke Damper EXCEPTIONS: 1. The smoke damper interferes with 909 mechanical smoke control system. 2. 0.019” thick duct and no openings to corridor serving the corridor. Non-CSFM Regulated Buildings  Fire & Smoke Dampers GroupB, F, M, S, & U, except as required in Section 111. NOSMOKE DAMPERS IN SPRINKLERED BLDG Same exceptions as SFM Regulated Buildings

  14. Smoke Barriers – 716.5.52007 Damper Requirements Bisects each floor of an underground building, bisects each patient floor of a hospital, hospital egress & areas of refuge. All Buildings  Smoke Dampers EXCEPTION: Openings in steel ducts limited to a single smoke compartment. Note: Fire damper requirements are not clearly spelled out, but it’s a safe bet that they should be included given the 1-hour fire resistance rating of all smoke barriers.

  15. Smoke Partition – 710.72007 Damper Requirements Smoke partitions are typically not fire-resistance rated and are constructed to limit the transfer of smoke. • Locations: Elevator Lobby Alternative (707.14.1) CSFM Regulated Buildings  Smoke Dampers GroupA, E, H, I, L, & R, High-Rise buildings, & others per Section 111. EXCEPTIONS: 1. The smoke damper interferes with 909 smoke control system. 2. 0.019” thick duct and no openings to corridor serving the corridor. Non-CSFM Regulated Buildings  Smoke Dampers GroupB, F, M, S, & U, except as required in Section 111. TRANSFER OPENINGS ONLY EXCEPTIONS: 1. The smoke damper interferes with 909 smoke control system.

  16. Membrane Penetrations – 716.6.22007 Damper Requirements Ducts and air transfer openings that penetrate the ceiling membrane (NOT the floor or roof) of a fire-resistance rated floor/ceiling or roof/ceiling assembly shall be protected by either: 1. A shaft enclosure in accordance with Section 707, OR, 2. A ceiling radiation damper installed at the ceiling line. EXCEPTIONS: 1. Tested per ASTM E119 without a ceiling radiation damper. 2. Exhaust ducts are located within the cavity of the wall, are protected per 712.4.1.2, and do NOT pass through another dwelling unit or tenant space. Note: The above applies to ALL BUILDINGS.

  17. Fire Damper Actuating Device The fire damper shall close upon actuation one of the following: • The operating temperature is ~ 50°F > the normal duct temperature, but not < 160°F. • The operating temperature is ≤ 286°F where located in a 909 smoke control system. • Combination fire/smoke dampers located in a 909 smoke control systemThe operating temperature ≤ the UL 555S degradation test temperature and is: • ~ 50°F > the maximum smoke control system designed operating temperature, AND • ≤ 350°F Note: 1. The above applies to ALL BUILDINGS 2. Option 1 & 2 matches 2001-CBC Section 713.101 NO CHANGE 3. Option 3 is NEW

  18. Eliminates Dual Temperature Systems Eliminates Emergency Override @ Damper  Simplified Design One Less Circuit to Wire and Program  Reduces Cost Damper Closure @ Max Temp  Maintains Safety Fire Damper Actuating Device 350°F Maximum Temperature Smoke Detector Override Only in 2007-CBC Fire Damper Override Required in2001-CBC Dual Temperature Circuit2001-CBC (T >286°F) Single Temperature Circuit2007-CBC

  19. The smoke damper shall close upon actuation of a listed smoke detector installed in accordance with 907.10 and one of the following: A duct mounted smoke detector installed within 5 feet of the damper. A spot-type detector where a damper is installed above smoke barrier doors. A spot-type detector installed within 5 feet of an unducted damper. Where a damper is installed in a corridor wall or ceiling, the damper shall be permitted to be controlled by a smoke detection system installed in the corridor. A total-coverage smoke detector system. Smoke Damper– 716.3.2.1 Actuating Device Note: 1. The above applies to ALL BUILDINGS 2. The above matches 2001-CBC Section 713.10  NO CHANGE

  20. 2007-CBC 402.9 – Covered Malls 403.13 – High-Rise Buildings 404.4 – Atriums 405.5 – Underground Buildings 408.8 – Windowless Buildings (I-3) 410.3.7.2 – Stage & Platforms 1025.6.2.1 – Assembly (Means of Egress) Smoke Control Required Locations 2001-CBC • 404.3.3 – Covered Malls • 403.4 – High-Rise Buildings (B & R-1) • 402.2 – Atria • 405.3.3.1 – Stages & Platforms

  21. Summary 2007-CBC  Big Changes • CAUTION CSFM vs. NON-CSFM Regulated Buildings • CSFM Bldg  Similar to 2001-CBC • NON-CSFM  Big Difference • New Format Barrier Driven + Detail + Trade-Offs • 350°F Single Temp Closure Simple + Cost + Safety
