AWC Desired Outcomes on International Building Code (IBC) Public Comments
Based on Public Comment Hearings
Oct. 19 – 25, 2016
Kansas City, Missouri

The ICC membership took Public Comment Hearing (PCH) action on proposed changes to the 2015 International Building Code (IBC) in Kansas City, MO, October 19 – October 25, 2016. The PCH results set the agenda for the cdpACCESS Online Governmental Consensus Vote. During a 2-week period starting November 8, 2016, cdpACCESS will be available for online voting. Validated Governmental Member Voting Representatives code officials will be voting online, determining the final action on these results.

AWC supports the following cdpACCESS actions on the 2015 IBC code changes. Please do not hesitate to contact AWC staff if you have questions or would like to discuss the AWC positions.

 

Proposal Number Description AWC Voting Recommendation
ADM6 Part 1 Proposal by SBCA proposes poor language in the definition of Approved Agency; the proposal as modified by the public comment addresses AWC concerns. Parts 2, 3, and 4 shown below were modified similarly by committee. Voting recommendation: AMPC on Part 1, AM on all other parts. AMPC
ADM6 Part 2 Proposal by SBCA proposes poor language in the definition of Approved Agency; the proposal as modified by the public comment addresses AWC concerns. Parts 2, 3, and 4 shown below were modified similarly by committee. Voting recommendation: AMPC on Part 1, AM on all other parts. AM
ADM6 Part 3 Proposal by SBCA proposes poor language in the definition of Approved Agency; the proposal as modified by the public comment addresses AWC concerns. Parts 2, 3, and 4 shown below were modified similarly by committee. Voting recommendation: AMPC on Part 1, AM on all other parts. AM
ADM6 Part 4 Proposal by SBCA proposes poor language in the definition of Approved Agency; the proposal as modified by the public comment addresses AWC concerns. Parts 2, 3, and 4 shown below were modified similarly by committee. Voting recommendation: AMPC on Part 1, AM on all other parts. AM
ADM74 This proposal contains troublesome language that would require all fire resistant assemblies in the IRC be tested assemblies. AWC would have supported PC 2 because it cleaned up the language adequately, but the PC not able to be moved. D
ADM77 AWC proposal which includes details of balcony protection in construction documents; as modified by a public comment (AMPC1) improves the language proposed for the IEBC to make sure it only applies to new balconies. AMPC
ADM87 AWC proposal requiring the inspection of balconies structures exposed to weather that are protected by an impervious moisture barrier was approved as modified by two public comments. One improved language proposed for the IEBC to make sure it applies to new balconies only and the other was an editorial improvement strengthening the inspection requirement. AMPC 1+2
ADM94 Most of ADM-94 was AM Committee and also AM at the public comment hearing; this portion includes updated AWC standards AM
ADM94 (ASCE 7-16) At debates at the Committee Action Hearing, ASCE 7-16 was Approved as Submitted by the committee but a floor motion for Approved as Modified to revert the base reference to the 2010 edition with Supplement No. 1 was successful. At the Committee Action Hearing it was Approved as Submitted (with the reference being to the 2016 edition). AS
RE26 The proposal would add new columns to the residential prescriptive R-value table to provide cavity insulation-only and continuous insulation-only columns, but the cavity insulation-only specified does not correspond to the U-factor table, the R-value being too large. Makes the table overly complex. The public comment does not fix it. D
RE28 Provides energy-equivalent options for adjusted wood frame wall R-values when using lower U-factor fenestration in Climate Zones 6 and 7 in the residential prescriptive R-value table. AMPC 1
RE30 As modified by the committee, this change requires the framing factor to be calculated or the stud spacing to be a maximum of 24 inches on center. D
RE51 Adds cross-laminated timber and structural composite timber to the definition of mass walls in the residential provisions. AMPC 2
RE100 Clarifies that ducts in attics under specified amounts of insulation provide similar performance as ducts in conditioned space, provided they meet specified criteria and duct tightness requirements. AM
RE134 Allows for mechanical equipment efficiency credit in the residential performance path while limiting total UA increase to 15% and the fenestration SHGC in Climates Zones 1 through 3 to 0.40. AM
RE135 Requires the thermal envelope in the performance path of the residential provisions to meet the prescriptive R-value or U-factor values of the 2009 code. D
RE145 Makes the fenestration area in the standard reference design of the performance path to be the same as proposed for the building. This would allow unlimited area of fenestration without any compensation in building performance. D
RE146 Establishes in the reference design of the performance path a baseline of 15% fenestration area regardless of the proposed design. Creates an equitable accounting for the effect of fenestration in the design. AS
RE156 Changes the thermal envelope "backstop" of the Energy Rating Index method from the prescriptive values of the 2009 code to the current code with 15% less stringency and a maximum fenestration SHGC of 0.40 in Climate Zones 1 through 3. This proposal was disapproved at the public comment hearing in favor of RE173's public comment 1, which also sets a backstop. However, RE156 is the preferred method as it allows more flexibility, such as the UA method, instead of limiting to previous editions R-value or U-factor table. AM
RE173 The original proposal adjusted (increased) the maximum index scores in the Energy Rating Index (ERI) alternative. The approved public comment adds a requirement that when on-site renewable energy is included in the calculation, the building thermal envelope must conform to the levels of efficiency in the R-value or U-factor provisions of the 2015 code. Although RE156 is preferable as a backstop, this one achieves compromise and makes the ERI path usable with more achievable index scores. AMPC
RE179 Adds a new mandatory section for "Additional Energy Efficiency" requiring the building design to achieve a minimum number of "flex points" credits. This would add unnecessary complexity to the code and would not provide enough accountability for threshold provisions. D
CE37 Creates an outcome-based performance path through the monitoring of actual energy use in buildings. This could unfairly penalize densification of buildings and long hours of operation, resulting in the building of more structures with reduced use, which is not energy efficient. It also presents unique enforcement challenges. D
CE54 Revises R-values and U-factors in the prescriptive building thermal envelope tables to match the more restrictive of ASHRAE 90.1-2013and the 2015 IECC. D
CE57 Aligns the R-values to the existing U-factors for wood framed buildings in Climate Zone 5, Group R, in the prescriptive commercial building envelope provisions. AS
G6 Part II Adds definitions for Grade (Lumber) and Design Value (Lumber) to the IRC. The proposed definition for Design Value (Lumber) is unclear and prone to misapplication when used outside of the context of PS20 due to use of terms like "data" and "representative" in the definition. D
WUIC3 Proposal adds performance criteria for exterior walls in Class 1 Ignition Resistant Construction which will make sure no material that performs well will be excluded, and conversely that no material which does not perform will be included. The ASTM E2707 standard was developed as a consequence of wildfire experience in the state of California, and mirrors the standards of the California State Fire Marshal's office. The proposed acceptance criteria are consistent with that used for regulation in the State of California. This change would make Section 504.5 functionally equivalent to Clause 707A.3(5), Chapter 7A-Materials and Construction Methods for Exterior Wildfire Exposure of the California Building Code 2013. AS
WUIC4 Would provide alternative means of compliance for appendages and projections in Class 1 Ignition Resistant Construction and would narrow the scope of the provisions to regulate only the walking surfaces of such appendages, mirroring the approach by the State of California. The proposal references ASTM deck fire test standards developed from the California standards, and uses acceptance criteria from these standards, providing practical alternatives for decks and their fire performance. AS
WUIC6 The proposal adds performance criteria for exterior walls in Class 2 Ignition Resistant which will make sure no material that performs well will be excluded, and conversely that no material which does not perform will be included. The ASTM E2707 standard was developed as a consequence of wildfire experience in the state of California, and mirrors the standards of the California State Fire Marshal's office. The proposed acceptance criteria are consistent with that used for regulation in the State of California. This change would make Section 504.5 functionally equivalent to Clause 707A.3(5), Chapter 7A-Materials and Construction Methods for Exterior Wildfire Exposure of the California Building Code 2013. AS
WUIC7 Would provide alternative means of compliance for appendages and projections in Class 2 Ignition Resistant Construction and would narrow the scope of the provisions to regulate only the walking surfaces of such appendages, mirroring the approach by the State of California. The proposal references ASTM deck fire test standards developed from the California standards, and uses acceptance criteria from these standards, providing practical alternatives for decks and their fire performance. AS
F37 Would require buildings of Type III, IV, and V construction to be provided with at least two fire apparatus roads. The proposal would make it nearly impossible to build Types III, IV, and V buildings on lots that do not have an excess of open space. D
F166 Would provide a sprinkler exception for detached noncombustible canopies which would cause confusion by implying that combustible canopies are always required to be sprinklered, which they are not. D
F172 Establishes new allowable height criteria for unprotected attics in Type III, IV, and V buildings protected by an NFPA 13R sprinkler system. Requires alternatives for attic protection when the attic exceeds 55 feet above the lowest level of required fire department vehicle access. The proposal as modified by the committee achieved consensus from affected parties and is a reasonable approach. AM
F333 Proposes a new requirement for firefighting vehicle access within 150 feet of two sides of the building. The proposal ties the new requirements to "construction utilizing combustible materials" which is too indefinite (all construction has combustible materials on site) and might be interpreted to apply only to certain construction types. In addition, the two-story height threshold for additional access is too restrictive. D
F336 Requires sprinkler systems in Type III, IV, and V buildings to be operational in lower stories before construction exceeds 40 feet in height. It is unfeasible under current sprinkler standards to provide an operational sprinkler system as the building is being constructed. D
RB20 Revises components and cladding wind loads to coincide with ASCE 7-16. This load basis is consistent with basis of engineered design loads approved during CAH and PCH for IBC. AS
RB68 The proposal as modified by both the committee and an AWC public comment (PC 1) would clarify that crawl spaces containing heating appliances only (both fuel-fired and electric) would require floor membrane protection above. Other appliances such as sump pumps will not trigger the protection requirement. AMPC 1
RB69 Would remove the 2x10 floor joist exception to the floor protective membrane provisions of the code, requiring all exposed floor assemblies, including dimension lumber of 2x10 and greater, to be protected. Solid sawn lumber was established as the acceptable baseline with fire service support. Testing data and actual fire experience do not support the inclusion of minimum-size dimension lumber within the protection trigger, and the body of comparative test data also does not support elimination of the recognized baseline. D
RB113 Adds requirement for exterior stairs of dwellings to maintain a 5-foot fire separation distance from lot lines. It has not been demonstrated that exterior stairs have been a problem in regard to fire separation distance, and could cause hardship in locating dwellings on lots. D
RB147 Would eliminate 23/32-inch wood structural panels from construction that can serve as a thermal barrier for the protection of foam plastic. Wood structural panels of lesser thickness are explicitly permitted to protect foam plastic in attics and crawl spaces, and the provision for WSPs as thermal barriers was reintroduced into the previous edition of the code. The proposal is overly restrictive for dwellings. D
RB200 Combines deck beam provisions into one section; provides for single ply beam spans; improves language and diagrams. The public comment eliminates poor code language. AMPC 1
RB209 Cleans ups and reformats decking span provisions and provides for the approval of alternate decking or fastener systems; AWC's public comment provides appropriate code language. AMPC 1
RB281 Adds a definition for "Absorptive Cladding" without adequate performance criteria; could prove troublesome for wood siding. D
RB302 Adds requirement that Grade D paper performance benchmark be Grade D paper complying with ASTM E2556 Type I; adds requirement that Grade D paper in exception comply with ASTM E2556 Type II; adds reference to new standard ASTM E2556 Standard Specification for Vapor Permeable Flexible Sheet Water-Resistive Barriers intended for Mechanical Attachment. Threatens the maintenance of Grade D paper as the baseline water resistive barrier. D
RB311 Adds requirement that FRTW be listed, cites ASTM E2768 as an alternative test. Testing provisions are still evolving and there is no significant benefit to adding the standard as a separate option D
RB312 Attempts to clarify that paints, coating, stains, and other surface treatments should not be considered FRTW produced by "other means during manufacture" in the code, but contains language that can be misinterpreted to prohibit these altogether. The public comment would have eliminated concerns but it was either not considered or disapproved. D
RB313 The proposal eliminates a provision that permits wood structural panels to be tested only on the front and back sides. D
S7 Requires that ventilation openings be provided similar to rafter spaces when the floor structure of exterior balconies and decks are enclosed. This is a necessary proposal for the safety and longevity of deck structures. AMPC 1
S78 Proposal removes LRFD and ASD load combinations and references ASCE 7-16 for them. A public comment retaining the alternative basic load combinations was approved to properly address snow loads. AMPC 1
S103 Updates snow load map with ASCE 7-16 snow load map changes and includes references to location specific snow maps in ASCE 7-16. AMPC1
S110 Updates information based on ASCE 7-16 design rain loads. AMPC1
S114 Updates seismic design to agree with ASCE 7-16. AMPC1
S145 With the committee modification, the proposal appropriately clarifies nail spacing trigger for special inspection of wood. AM
S166 Proposed revisions in Ch 18 to update references to ASCE 7-16. AS
S259 Removes redundancy in code language and clarifies the applicable strength adjustments, consistent with NDS, for pressure preservative treated wood and FRTW. AMPC1
S260 Adds requirement that FRTW be listed, cites ASTM E2768 as an alternative test. Testing provisions are still evolving and there is no significant benefit to adding the standard as a separate option. D
S263 Parts I and II Requires testing of all side of FRTW products and does not address the issue that the change is intending to resolve. The scope of the current section is changed and would increase testing requirements. D
S264 The proposal eliminates a provision that permits wood structural panels to be tested only on the front and back sides. D
S277 Clarifies permitted locations and applications for preservative treated glued laminated timber Support as modified by joint modification prepared by APA and AWC. AMPC1
S279 Requires moisture barrier systems of moisture-permeable floor toppings supported by wood framing to include elements that provide positive drainage. Change is important for the safety of elevated balconies and walking surfaces. AMPC1

Building and Fire Officials – Get Connected!
"Your website and publications have been a useful source of good information that I have shared with builders and fellow plans reviewers."
– Code Official - Spotsylvania County, Virginia

The American Wood Council (AWC) is proud to introduce its new program, Code Official Connections! It is free to qualified governmental employees* and is designed for the professional needs of the code administration and enforcement community.

The AWC Code Official Connections program ensures code officials are among the first recipients of the most up-to-date building code related wood design and construction information and technical support regarding traditional and engineered wood products. Code officials enjoy a wide array of AWC offerings including:

  • One free AWC/ANSI electronic standard (PDF) of your choosing (i.e., NDS, SDPWS, or WCFM) at sign up
  • Free building department access to WoodWorks® software
  • Free electronic or discounted printed Technical Publications
  • WoodPost, a bi-weekly e-newsletter tailored for code officials
  • Announcements of education programs offering ICC Preferred Provider CEUs and other credits
  • Easy-to-use online tools (e.g., the Maximum Span Calculator for Wood Joists and Rafters as well as PDFs of the Code Conforming Wood Design guide and the Prescriptive Residential Wood Deck Construction Guide)

To receive the free electronic standard and access to WoodWorks, be sure your account profile indicates that you are interested in receiving them. They will be sent to you electronically. Publications discounts will automatically show up in our shopping cart.

AWC has also developed a service to respond to technical inquiries on building codes, standards, and other design information regarding traditional and engineered wood products. Contact the AWC Help Desk at 202-463-4713, or by e-mail at info@awc.org.
