Welcome,
introductions, housekeeping, review agenda and previous
meeting’s progress report
As a follow-up to the previous
meeting, Mamayek reported that in
regards to IMC 304.10: 3-inch pads are available as a common
option in foam or foam with a concrete cover, but not in concrete,
which is poured anyway, so the 3-inch requirement is no longer
considered an issue. The council discussed IMC 502.14, and decided to eliminate Exception 3.
Finalize
potential Wisconsin modifications regarding IMC Table 403.3
option, IMC 307.2.3, and IMC 401.4, and finalize concepts and changes
to the HVAC code requirements.
- Comm 64.0403 Mechanical Ventilation: Keep Wisconsin modification, but amend so Table 64.0403 can be used as an alternate for IMC Table 403.3, as long as the chosen method is utilized in its entirety. - Create Comm 64.0307 to eliminate all of IMC 307.2.3. - Comm 64.0401
Ventilation: Modify the current Wisconsin
modifications as necessary to match up with text and numbering changes
to the 2009 IMC, includes the following:

Fire Station #11, 4011 Morgan Way, Madison, WI Welcome, introductions, housekeeping, review agenda and previous meeting’s progress report Michael Mamayek opened the meeting with introductions. The progress report of the September 24, 2009, was approved as written, and the agenda was approved as written. As a follow-up to the previous meeting, Mamayek reported that in regards to IMC 304.10: 3” pads are available as a common option in foam or foam with a concrete cover, but not in concrete, which is poured anyway, so the 3” requirement is no longer considered an issue. Continue reviewing changes within 2009 editions of IMC and IFGC IMC 1209.5: The Council recommended to the agency that they bring this requirement to the attention of the Energy Conservation Code Council and the umbrella councils, who may want to refer to this section in Chapter Comm 63: Energy Conservation. Staff will research if this requirement is in the International Residential Code. The Council voted to recommend that slab-on-grade and basement thermal barriers be required to have a minimum R-value of 5. The Council made no recommendations regarding the changes to the IFGC. Review related Wisconsin modifications from the current Wisconsin Commercial Building Code

Division
Updates.
Senate Bill SB 325. This bill is about improving indoor air quality in schools. It affects existing schools, and it requires the department to develop rules. Building code update. The department’s goal is to submit the final rule draft for the building code update to the legislature by August 31, 2006. There will be a joint meeting of the Commercial Building Code Council and Multifamily Dwelling Code Council on December 8, 2005, to review the proposed changes from the various specialty councils, including this council. The update package will also include rules relating to fire prevention, explosives, fireworks, and existing buildings. International Residential Code. Jim Quast distributed copies of the mechanical system requirements taken from the International Residential Code, starting with chapter 13 of that code. (Copies of all distributed documents are included with this report for members not in attendance.) The department is proposing to reference the IRC for the design and construction of rowhouses and townhouses that are commercial buildings. Most of the mechanical system requirements in the IRC are the same as in the IMC. Review Final Actions 2006 IMC and IFGC. Jim distributed copies of the ICC final actions on the IFGC and IMC proposed changes for 2006. These 2 documents included excerpts of where final ICC actions were different than the committee action as the result of public hearing comments. These documents are being provided to council members for review in order to see what changed in final actions where public hearing comments were received by the ICC. Mike noted that it is important for all council members to review these 2 documents along with the 2 committee action documents distributed at the May 3 council meeting that list the changes in the IMC and IFGC that were not challenged. Review Unresolved Issues. The council reviewed the list of 12 unresolved issues that was previously sent to all members. Comm 64.1300 Coverage of chapter Comm 10. Jim noted that chapter 13 of the IMC should be kept. There may be some overlap between Comm 10 and chapter 13, but there is no conflict. The council recommended keeping chapter 13 of the IMC. Comm 64.1500 (2) (a) Edition of AIA guidelines. Jim noted that the current edition of the AIA guidelines is 2001; the proposed rules will adopt that edition. In a discussion of footnote m in Table 64.0403, it was noted that all of the requirements in the AIA guidelines are required by the Department of Health and Family Services and to receive federal money. Therefore, the guidelines must be followed. IMC 607.5.5.1 3 questions relating to Exception 2. Jim noted that the IMC is adding R occupancies as another exception. The council discussed what is meant by powered continuously in accordance with section 909.11 of the IBC. It was agreed that it does not mean run continuously. No changes were recommended. IMC 306.6 How interpreted and enforced. It was agreed that the 30-inch edge referenced in the requirement is always considered to be the lower edge of the roof. No changes were recommended. IMC 307.2.3 – 4 and Exception How interpreted and enforced. It was agreed that this requirement has not been a problem; it is an issue between the building owner and the designer. No changes were recommended. IMC 1202.5 Addition of ASME B16.51. Jim reported that the ICC proponent withdrew the proposal to add the adoption of ASME B16.51. No changes were recommended. Comm 65.0304(1) Need for this subsection. Jim distributed a document that summarized the IFGC requirements that address the same subjects as the IMC sections 705, 706 and 707. The council agreed that IFGC sections 304.9, 304.1 and 304.7 sufficiently cover the subjects addressed in the IMC sections. The council recommended deleting Comm 65.0304(1). Comm 65.0400 Testing requirements in NFPA 54. Jim reported that the testing after service interruption requirement in NFPA 54 has been in that standard for many years. The council agreed that it has not been a problem, and recommended no changes. Comm 65.0503(1) Venting differences between IMC and IFGC. Jim distributed copies of sketches from the IMC and IFGC to compare the differences between the 2 codes dealing with the locations of exhaust terminations. The council noted differences in the exhaust termination requirements for the 2 codes. It was agreed that different fuels have different requirements. The council recommended deleting Comm 65.0503(1). Comm 65.0503(2) Venting differences between IMC and IFGC. Same situation as issue 9; the council recommended deleting Comm 65.0503(2). IFGC 505.1.1 Damper in kitchen hood duct. The council agreed that a damper is permitted within the duct serving a kitchen hood; the damper must be listed for the application. No changes were recommended. Comm 64.0401(3) Need for this subsection. It was noted that the building code contains the same requirement as IMC 401.4, and that the substitution in Comm 64.0401(3) for IMC 401.4 is not consistent with the building code. The council recommended deleting Comm 64.0401 (3). At this time, Mike distributed copies of a page containing 3 recommendations for changes in IBC sections 707 and 715. Jim Smith, Building Code Program Manager, attended at this time to listen to Mike’s proposal. Based on previous council discussion, Mike withdrew recommendation #2. The first recommendation added Exception 12 under IBC section 707.2, relating to eliminating a shaft enclosure for ducts and air transfer openings that penetrate a fire-rated floor/ceiling assembly provided fire dampers protect each assembly penetration. The third recommendation added Exception 2 under IBC section 715.5.4.1, relating to smoke dampers not required in corridor penetrations where smoke detectors are provided in the return air system serving the corridors. Mike asked that Jim Smith take the recommendations to the Commercial Building Code Council. Ventilation Issues. The council discussed the need for Wisconsin modifications regarding natural ventilation and exhaust ventilation. In particular, the council discussed the requirements under the air change rate column in Table 64.0403. The dashes in that column result in the question as to what the air change requirements are if mechanical ventilation is chosen even though natural ventilation is allowed. The council agreed that the dashes were meant to mean Not Required, and that NR should be inserted in place of the dashes. International Existing Building Code. Jim distributed copies of excerpts from the 2006 International Existing Building Code, starting with chapter 4 - Classification of Work. This document listed the changes regarding mechanical issues in the 2006 IEBC, and is for the council’s information. The IEBC will be proposed as the basis for the new chapter Comm 66 in the building code update. Discussion of Working Draft. The council reviewed Working Draft No. 1 that was previously sent to all members. Two major changes in the draft from the current code include a new temperature table, Table 64.0309, and a new footnote q in Table 64.0403 relating to the use of natural ventilation. In discussing footnote b relating to recirculation of air, it was noted that interpretation of that footnote requires some training of designers and enforcers. The council recommended inserting NA (Not Applicable) and NR (Not Required), as applicable, in Table 64.0403 in place of the dashes. The council also recommended to have one line entry for “Car washes, enclosed” with natural ventilation allowed, and deleting the 2 sub-categories for car washes and the required exhaust ventilation. Under Comm 64.0506 (2), the council recommended adding wording to require the sealant to be listed and labeled for the application. Issues from the Energy Conservation Council. Mike asked the council to discuss the following issues that were deferred from the Energy Conservation Council. Comm 63.1027 Zone Controls and 63.1028 Humidity Controls. Although the energy council deferred these requirements to this council, this council recommended no changes incorporating these requirements into chapter Comm 64. IECC section 803.2.5.1 Energy Recovery Ventilation Systems. Concern was noted as to whether energy recovery ventilation systems requirements overlap with economizer requirements. The council indicated that this is not a problem, and there was no need to address it. Comm 63.1023 Load Calculations for Sizing and 63.1024 System and Equipment Sizing. Concern was again noted as to whether these requirements relating to sizing of systems and equipment overlap with requirements in Comm 64 relating to HVAC. The council indicated that this is not a problem, and there was no need to address it. Ventilation Damper Settings for Multi-Use Spaces. The council agreed that this is an educational issue, and no code changes were recommended. Set Next Meeting and Adjourn. The next meeting was scheduled for Thursday, December 1, 2005, as a conference call meeting starting at 9:30 a.m. Council members will be notified regarding the telephone number to call for the meeting. Members are asked to review all of the previously distributed documents regarding the ICC changes, and Draft No. 2 of the proposed Comm 63 and 64 changes. (Draft No. 2 is enclosed with this report.) Tuesday, June 14, 2005, 9:30 a.m.,Human Resource Room, First Floor, Thompson Commerce Center, 201 West Washington Avenue, Madison, Wisconsin Council member attendance: Richard Lund Absent, Michael Mamayek Present, Richard Pearson Present, John Periard Absent, Daniel Rehbein Present, Dan Rogers Present, David Stockland Present, Harry Sulzer Present Visitors: Scott Olson Staff: Jim Smith, Jim Quast, Ronald Acker 1. Welcome. Introductions and Review of Agenda. Chairperson Mike Mamayek opened the meeting. Council members were welcomed. The agenda was reviewed and no changes were made. 2. Review Progress Report (meeting summary) from May 3 Meeting. The Progress Report from the May 3, 2005 meeting was reviewed and approved as written.
3. Division Updates. 4. Fire Protection Dampers. Jim Smith addressed the council on the subject of fire protection dampers. The specialty council dealing with all types of passive fire resistance systems has met once. Some changes relating to smoke and fire dampers were put in the code effective 1/1/05 from the 2003 and 2004 IBC changes. The council discussed whether a fire damper can be installed in a grease hood. Because no prohibition for that installation can be found in the IBC or IMC, the damper can be installed. It was noted that the federal government or other state agencies may have additional fire protection requirements in order to obtain a license to operate a given occupancy, such as a hospital. The council discussed the requirements for smoke dampers in corridors as covered in IMC 607.5.4. It was noted that section 607 comes from the IBC. Some concerns were raised, and changes may need to be made in this section. The council also discussed plenum construction. It was noted that under IMC 602.2, plenums must be constructed of material permitted for the type of construction classification of the building. It was suggested that there should be a combined presentation to engineers and architects to train them on fire damper, smoke enclosure and shaft requirements. 5. IMC Chapter 4 – Ventilation. The council discussed the subject of ventilation in general, the use of natural ventilation and the requirement for 7.5 cfm of outside air per person. It was pointed out that the department wants to use the IMC as much as possible, and keep the Wisconsin changes to a minimum. The state code is more limiting than the IMC for the use of natural ventilation because of the design temperature limits of -10 and 95 degrees F. It was noted that the IMC allows natural ventilation and puts no limits or conditions on its use. Although the ASHRAE 62 standard has provisions for both natural ventilation and mechanical ventilation, the natural ventilation requirements are very general and limited. It was commented that the objective in making a code change is to allow turning off the mechanical ventilation system and still provide the needed ventilation for building occupants. The council recommended expanding the permitted use of natural ventilation by inserting a footnote in Table 64.0403 for the “no” items under the “Natural Ventilation Allowed” column. The footnote would allow natural ventilation where it is now prohibited provided an engineered analysis would account for the number of occupants and demonstrate that it meets the minimum temperature and air change rate requirements. Regarding the code requirement for the ventilation rate of 7.5 cfm of outside air per person, the council recommended not changing it because it is not causing any problems. At this time, the council reviewed the ventilation requirements in the 10-page document distributed at the May 3 meeting and titled “Wisconsin Modifications, Recommendations for 2006 International Mechanical Code”. The following is a brief summary of the council review of the Wisconsin ventilation modifications and the recommendations regarding the modifications. 64.0401 (1) Ventilation Required. Keep, and revise Table 64.0403 as recommended above. 64.0401 (2) When Required. Keep. 64.0401 (3) Exit Ventilation. The council questioned the need for this Wisconsin substitution requiring compliance with the IBC when the IMC rule being replaced comes from the IBC. The council suggested that the means of egress specialty council look at the IMC 401.4 requirements. In particular, the council questioned how the code could be met when cooling a hot vestibule. 64.0401 (4) Intake Openings. It was noted that the Wisconsin modifications are intended to clarify the intent of the IMC provisions. The council recommended deleting (b)4. because it is covered in IFGC 503.2.3, and adding the word “supply” at the end of (b)3. To eliminate repeating IMC language, the department will change (4)(a) to be an addition to IMC 401.5.1 and delete (4)(a)1. 64.0401 (5) Exhaust Openings. Keep. 64.0402 Natural Ventilation. Keep, and revise Table 64.0403 as recommended above. 64.0403 (1) Ventilation System. The council agreed to use the IMC 403.1 requirements, and recommended deleting the Wisconsin substitution in (1). 64.0403 (2) Outdoor Air Required. Keep. 64.0403 (3) Recirculation Prohibited. It was noted that this rule is not consistent with IMC Table 403.3 footnote b for allowing recirculation of air. The council agreed that the rule should allow recirculation of air within the same space, such as a garage or locker room. The council recommended that this rule be clarified to be consistent with the IMC recirculation requirements. 64.0403 (4) Recirculation of Air. Keep. 64.0403 (5) Transfer Air. Keep. 64.0403 (6) Ventilation Rates. Keep. 64.0403 (7) System Operation. Keep. 64.0403 (8) Common Ventilation System. Keep. 64.0403 (9) Temperature and Ventilation Table. Keep. 64.0404 (1) Enclosed Parking Garages. Keep. 64.0404 (2) Minimum Garage Ventilation. Keep. 6. Next Meeting/Adjournment. The next meeting has been tentatively scheduled for Tuesday, September 13, 2005, beginning at 9:30 a.m.

Welcome, Introductions and Review of Agenda. Chairperson Mike Mamayek opened the meeting. Council members were welcomed, and everyone introduced themselves and indicated the organization they represented. The agenda was reviewed and no changes were made. 2. Review meeting summary from March 29 Meeting. The meeting summary from the March 29, 2005 meeting was reviewed and approved as written.
3. Division Updates. -- Comm 5. Proposed rules relating to welder, electrician and plumber credentials are now at legislative committee review. The welder credential rules deal with the time period during which a certified welder may perform the welding procedures for which he or she is certified and with the identification of welding on structurally significant members. -- Comm 91. Proposed rules relating to potty parity are now at legislative committee review. These rules deal with equal speed of access to restroom facilities for males and females serving specialty event centers that are not buildings or structures, e.g., a park. -- Soil Erosion. Proposed rules relating to soil erosion are being drafted by division staff. The rules are intended to match up with EPA and DNR rules. -- Alteration and Change of Use Council. This council has been meeting to develop proposed rules dealing with existing buildings. The council is looking at the International Existing Building Code. 4. Review Summary of 2003 IFGC Revisions. The council reviewed the Summary of 2003 IFGC Revisions that was sent to all members on October 27, 2004 (and Emailed on April 27, 2005). The following is a brief summary of the council review of that document and the recommendations relating to the revisions in the 2003 IFGC. Where no recommendations were made, the 2003 IFGC revisions were acceptable. Section 202 Definitions. It was noted that the definition of “unusually tight construction” has been deleted from the IFGC, and that the combustion air requirements have been rewritten to account for this. Section 304.4 Makeup Air. The council reviewed the revisions to clarify the makeup air requirements, but made no recommendations. Section 310 Gas Pipe Bonding. It was noted that this section is all new; no recommendations were made. Section 501.8 Equipment Not Required to be Vented. It was noted that a Wisconsin modification deletes item 8 and revises item 10. Section 505.1.1 Commercial Cooking Appliances Vented by Exhaust Hoods. A brief discussion took place on the new requirements of this section relating to the operation of cooking appliances and kitchen hood exhaust systems. The council questioned how the interlocking requirement could be met. (See section 505.1.1 under 2004 IFGC revisions.) A question was raised if any damper was permitted within the ducts serving a kitchen hood; staff will research the matter. Section 612 Recirculating Direct-Fired Industrial Air Heaters. The location provisions of this section were revised for clarification. It was noted that the requirements do not prohibit the use of recirculating air heaters. Section 614.2 Duct Penetrations. It was pointed out that a sentence was added prohibiting fire dampers in dryer exhaust ducts. 5. Review Summary of 2004 IFGC Revisions. The council reviewed the Summary of 2004 IFGC Revisions that was sent to all members on October 27, 2004 (and Emailed on April 27, 2005). The following is a brief summary of the council review of that document and the recommendations relating to the revisions in the 2004 IFGC. Where no recommendations were made, the 2004 IFGC revisions were acceptable. Section 505.1.1 Commercial Cooking Appliances Vented by Exhaust Hoods. This revision created an exception relating to interlocking a cooking appliance with the exhaust hood system. The council recommended deleting section 505.1.1 and the Exception because of problems with the interlock when the system has a pilot light. It was also suggested that research of section 503 should be done because of the reference to 503 in section 505.1. It was further noted that there is a proposal for the 2006 edition to revise section 505.1 that will accomplish the council’s recommendation.
6. Miscellaneous Issues. Mechanical Draft Systems. Copies were distributed of a comparison table titled IFGC-IMC Comparison for Mechanical Draft Systems. This table should be reviewed for discussion at the next meeting. Intake Opening Separations. Copies were distributed of a comparison table titled Wisconsin Modification-IMC/IFGC Comparison for Intake Opening Separations. This table should be reviewed for discussion at the next meeting. Controls from IECC. Copies were distributed of a document
describing Comm 63 and IECC 2004 Supplement requirements relating to
humidity controls. This document should be reviewed for
discussion at the next meeting. 7. Next Meeting/Adjournment. The next meeting has been scheduled for Tuesday, June 14, 2005, beginning at 9:30 a.m. The main agenda topic will be ventilation.

3. Division
Updates.
4. Review Summary of 2004 IMC Revisions. The council began review of the Summary of 2004 IMC Revisions that was sent to all members on October 27, 2004. The following is a brief summary of the council review of that document and the recommendations relating to the revisions in the 2004 IMC. Section 106.3.1 Construction Documents. This section is not adopted, as chapter 1 of the IMC is not included as part of the building code. Section 202 Definitions. The definitions will be looked at as needed in reviewing the IMC revisions. Section 304.10 Guards. The council discussed if the guard needs to be on all 4 sides of the equipment. It was agreed that it does not. Section 306.6 Sloped Roofs. This revision clarified the requirements for providing service platforms and guards for equipment located on sloped roofs. The council discussed the interpretation of the 30 inches above grade wording. It was noted that the 30 inches requirement has been in the code for many years; and it has not been an issue because most of the time equipment is not installed on roofs with slopes of 3-in-12 or greater. The council asked staff to check on how this rule has been interpreted and enforced. Section 307.2.3 – 4 and Exception Drain Systems. This item and exception add another method to address protection from condensate drainage problems. The council discussed and questioned the meaning of “damage to any building components” in the introductory paragraph. For example, does it mean water stains on ceiling tile? The council asked staff to check on how this rule has been interpreted and enforced. Chapter 4 Sections. These sections were put on hold. Ventilation requirements will be discussed at a separate meeting. Section 506.3.3.1 Grease Duct Test. This new section requires a leakage test of a grease duct to be performed in the presence of a code official. The council questioned the need for this, especially when considering the cost involved and the availability of code officials. It was also noted that current duct requirements are comprehensive enough to negate the need for this test requirement. The council recommended deleting this section. Section 507.13 Capacity of Hoods. This revision clarified the minimum air capacity for exhaust hoods serving various types of appliances. The council recommended using this new language and also including the Wisconsin modification allowing engineered systems. Section 507.13.5 Dishwashing Appliances. This new section specifies the minimum airflow requirements for Type II hoods serving dishwaters. The council agreed that this requirement is not needed since airflows for Type II hoods are not specified for other equipment. The council recommended deleting this section. Section 1002.2.2 Temperature Limitation. This section is not adopted, as chapter 10 is replaced with chapters Comm 41 and 81 to 86. Table 1202.5 Hydronic Pipe Fittings. A code change proposal added a reference to ASME B16.51 in table 1202.5, but this change does not appear in the chapter 12 changes in the 2004 Supplement to the IMC. It also does not appear in the ASME table of standards in chapter 15of the supplement. The council asked staff to research this inconsistency. Section 1301.5 Tanks Abandoned or Removed. This section is not adopted, as chapter 13 is replaced with chapter Comm 10. 5. Review Wisconsin Modifications for Possible Deletion with Adoption of 2006 IFGC. Copies of a table titled Wisconsin Modifications, Recommendations for 2006 IFGC were previously Emailed to all members. This table was based on chapter Comm 65 before the code changes went into effect on January 1. The following is a brief summary of the council review of the Wisconsin modifications and the recommendations regarding the modifications. 65.0202 Definitions. The definition of “unusually tight construction” has been removed from the IFGC. Therefore, the Wisconsin substitution for that definition is not needed, and it was recommended to delete it. 65.0300 Space Heating Systems. Keep. 65.0301 Listing and Labeling. Keep. 65.0303 (1) Air Temperature. Keep. 65.0303 (2) Prohibited Locations. Keep. 65.0304 (1) Combustion Air. It was noted that the references to IMC sections 705, 706 and 707 may not be needed. It was recommended to delete this subsection, conditioned on the review of the new IFGC changes. 65.0304 (2) and (3) Unusually Tight Construction. Because the definition of “unusually tight construction” has been removed, it was recommended to delete these 2 subsections. 65.0304 (4) Combustion Air Ducts. The 12-inch above grade requirement is now in IFGC section 304.11-8. It was recommended to delete this subsection. 65.0305 (1) Installation Requirements. Upon review of the referenced IMC requirements, it was agreed that the IFGC requirements are consistent with the IMC. It was recommended to delete this subsection. 65.0305 (2) Final Test. The council agreed that the testing and balancing requirements in Comm 64.0313 do not pertain to gas appliances. It was recommended to delete this subsection. 65.0306 Access to Appliances. Because fans are not gas-fueled appliances, the council agreed that this section is not needed. It was recommended to delete this section. 65.0400 Gas Piping. It was noted that NFPA 54 replaces IFGC chapter 4 for consistency with chapter Comm 40, Gas Systems, which adopts NFPA 54. The council was asked to look at the testing requirements in NFPA 54 for possible discussion at a future meeting. 65.0501 (1) DHFS Information. Keep. 65.0501 (2) and (3) Unvented Appliances. Keep. 65.0503 (1) Mechanical Draft Systems. This subsection contains references to IMC sections for exit terminals for mechanical draft systems. The council recommended holding a decision on this subsection until staff can provide a more detailed review of the differences between the IMC and IFGC. 65.0503 (2) Vent Locations. A decision on this subsection was also put on hold for a comparison of the IMC versus IFGC. 65.0609 Duct Furnaces. Keep, and change the IFGC section number to 610.2. 65.0617 Furnaces. The council recommended deleting this section because the IFGC requirements in section 618.5 are the same as the IMC requirements. 65.0620 Unvented Room Heaters. Keep. 65.0629 Infrared Radiant Heaters. Keep, and change the IFGC section number to 630. 65.0630 Boilers. Keep, and change the IFGC section number to 631. 65.0700 Referenced Standards. Keep. 6. Next Meeting/Adjournment. The next meeting was scheduled for Tuesday, May 3, 2005, beginning at 9:30 a.m. The agenda will be to review the Summary of 2003 IFGC Revisions, Summary of 2004 IFGC Revisions, and miscellaneous unresolved issues. Tuesday, February 22, 2005, 9:30 a.m., Room 3B, Thompson Commerce Center, 201 West Washington Avenue, Madison, Wisconsin Council member attendance: Richard Lund, Absent; Michael Mamayek, Present; Richard Pearson, Present; John Periard, Absent; Daniel Rehbein, Present; Dan Rogers, Present; David Stockland, Present; Harry Sulzer, Present (Jim Wolf, alternate) Department of Safety and Professional Services staff: Jim Quast, Ronald Acker, John Spalding 1. Welcome, Introductions and Review of Agenda. Chairperson Mike Mamayek opened the meeting. Council members were welcomed, and everyone introduced themselves and indicated the organization they represented. The agenda was reviewed and no changes were made. 2. Review Progress Report from January 20 Meeting. The meeting summary from the January 20, 2005 meeting was reviewed and approved as written with a followup comment. The overly restrictive requirement under Comm 64.0900 (2) (a) comes from the AIA document, and that document should be monitored for future changes. 3. Division Updates. 4. Review Summary of 2003 IMC Revisions. The council began review of the Summary of 2003 IMC Revisions that was sent to all members on October 27, 2004. The following is a brief summary of the council review of that document and the recommendations relating to the revisions in the 2003 IMC. Section 202 Definitions. It was noted that there are many new definitions, such as for various styles of commercial kitchen hoods. The definitions were not reviewed, but will be looked at as needed in reviewing the IMC revisions. Section 301.14 Elevator Shafts. The prohibition for mechanical systems in elevator shafts was eliminated; it is now in section 303.8. Section 309.1 Space-heating Systems. This revision added a sentence from the IBC indicating that space heating cannot be achieved by means of portable space heaters. The council recommended that the department develop a table or language at this point in the code for heating requirements rather than combining heating and ventilation requirements as is currently done in Table 64.0403. Section 502.5 Valve-regulated Lead-acid Batteries. These provisions were added from the IFC. The council discussed different ventilation requirements for stationary and valve-regulated lead-acid battery systems, but no changes were recommended. Section 507.2 Where Type I or II Hoods are Required. These revisions clarified the introductory language relating to where type I and II hoods are required, and eliminated the provision for a type II hood to serve a commercial dishwashing machine. The council discussed different situations where type I and II hoods are required and how the rules are enforced. Section 507.16 Performance Test. The council questioned the need to revise the IMC wording relating to the permit holder because a permit is not always required. The same concern also occurs in section 507.16.1. Section 508.1 Makeup Air. An exception for dwelling units was removed in the IMC because the rule only applies to commercial kitchens. Section 514 Energy Recovery Ventilation Systems. The council discussed types of hazardous exhaust systems that could not use energy recovery ventilation systems. The prohibited applications in the IMC may be overly restrictive and may prevent future use of energy recovery ventilation systems resulting from new technology. The council recommended that wording be added to allow engineered systems if problems with corrosion, cross contamination and fouling are addressed, similar to other rules allowing engineered systems. Section 601.2 Air Movement in Egress Elements. The council discussed the size and types of rooms that can use an exit access corridor as a source of makeup air. It was noted that the corresponding rule in the 2003 IBC is section 1016.4. The council questioned the need for the listing of the rooms in Exception 1, as it tends to cause more confusion than it helps. The council recommended deleting the phrase "including toilet rooms, bathrooms, dressing rooms, smoking lounges and janitor closets". Section 607.5.5.1 Penetrations of Shaft Enclosures. It was noted that the entire section 607 is from the IBC. The council discussed and questioned the need for Exception 2. In particular, the council had 3 questions regarding this exception: 1. Why limit the exception requirements to Group 3 occupancies only?; 2. Why limit it to bathrooms and toilet rooms?; 3. Why does the exhaust fan need to be powered continuously? [Needs to be coordinated with the IBC] Section 607.6.1 Through Penetrations. The council questioned the reason for the exception. It was suggested to monitor the IBC update to sees if any changes are made to this section. Section 801.20 Plastic Vent Joints. It was noted that this section is new and it is confusing because some solvent cements don’t require a primer. The council recommended deleting the last 3 sentences and the exception. 5. Next
Meeting/Adjournment. The council
completed the review of the 2003 IMC revisions. The next meeting was
scheduled for Tuesday, March 29, 2005, beginning at 9:30 a.m. The
agenda will be to review the 2004 IMC revisions, the 2003 and 2004 IFGC
revisions, and the Wisconsin modifications for possible deletion with
adoption of 2006 IFGC. Thursday, January 20, 2005, 9:30 a.m., Room 3C, Thompson Commerce Center, 201 West Washington Avenue, Madison, Wisconsin Committee Member Attendance: Richard Lund, Excused; Michael Mamayek, Present; Richard Pearson, Present; John Periard, Absent; Daniel Rehbein, Present; Dan Rogers, Present; David Stockland, Present; Harry Sulzer, Absent. Visitors: Scott Olsen Department of Safety and Professional Services staff: Jim Quast, Ronald Acker, John Spalding 1. Welcome, Introductions and Review of Agenda. Chairperson Mike Mamayek opened the meeting. Council members were welcomed, and everyone introduced themselves and indicated the organization they represented. 2. Review Progress Report from November 11 Meeting. The Meeting Summary from the November 11, 2004 meeting was reviewed and approved as written. In response to a question, it was responded that the hearings on the International Code Council (ICC) code changes will be held in February and March of this year, and the department public hearings on the changes to chapters Comm 61-65 are expected to be held in early 2006. 3. Division Updates. Copies were distributed of the rule draft
pages
containing the changes in chapters Comm 64 and 65 that went into effect
on January 1, 2005. Copies were also distributed of the updated
Commercial Building Code, chapters Comm 61-65, effective January 1,
2005. 4. Review Wisconsin Modifications for Possible Deletion with
Adoption of 2006 IMC. Copies were distributed of a table titled
Wisconsin Modifications, Recommendations for 2006 IMC. This table was
based on chapter Comm 64 before the code changes went into effect on
January 1. The council agreed to hold discussion of ventilation issues
for a separate meeting sometime after the ICC hearings in February. The
following is a brief summary of the council review of the Wisconsin
modifications and the recommendations regarding the modifications. 5. Next Meeting/Adjournment. The next meeting was scheduled for Tuesday, February 22, 2005, beginning at 9:30 a.m. The agenda will be to review the 2003 and 2004 IMC changes, excluding chapter 4 - Ventilation, and the Wisconsin modifications to the IFGC. Thursday, November 11, 2004, 10 a.m., Room 3B, Thompson Commerce Center, 201 West Washington Avenue, Madison, Wisconsin Committee Member Attendance: Richard Lund - Absent; Michael Mamayek - Present; Richard Pearson - Present; John Periard - Present (Jennifer Cape, alternate); Daniel Rehbein - Present; David Stockland - Present; Harry Sulzer - Absent. Visitors: Louie Pody, Mike Utzinger, Francis Faber Staff: Jim Quast, Ronald Acker, John Spalding 1. Welcome and Introductions. Council members were welcomed and thanked for offering their time and effort in advising the department on the update of the HVAC code. Everyone introduced themselves and indicated the organization they represented. 2. Discuss Council Manual, Meeting Procedures and Election of Chairperson. The Advisory Council Manual that was previously sent to all council members was reviewed. Significant items pointed out were council member responsibilities, chairperson responsibilities and meeting ground rules. The council membership list was reviewed and any changes or corrections were noted. (An updated membership list is included with this report. The vacant position for the Sheet Metal and Air Conditioning Contractors Association has been filled.) The department wants to communicate more by electronic means, and has offered a method by which persons can receive Emails regarding council activities and program news. Persons can sign up to receive the Emails through the Safety and Buildings Division home page located at www.commerce.wi.gov/SB/. Meetings are generally conducted informally, with open discussion and no motions or voting unless necessary to resolve an issue. The council is advisory to the Department of Safety and Professional Services, and department management may make changes to the council's recommendations. The council agreed to elect a chairperson at this time. Nominations were opened; Mike Mamayek was nominated, seconded and unanimously elected as chairperson. 3. Code Development Update. Copies were distributed of the 2003 International Mechanical Code (IMC), 2003 International Fuel Gas Code (IFGC) and 2004 Supplement to the International Codes. (Copies of all distributed material are included with this report for absent members.) The 2004 supplement contains the changes to all of the 2003 international codes. Jim Quast informed the council of the overall timeline for the code update. The department's goal is to update the state HVAC code with as few modifications and additions as possible. Hearings on the changes to the international codes will be held in February or March, 2005. By the end of 2005, the revisions for the 2006 international codes will be known, with the publication of the new editions available in early 2006. Department public hearings on the HVAC code update are expected to be held in early 2006. The rulemaking process adopting the 2006 editions of the IMC and IFGC should be completed by the end of 2006, and the revised rules would then be effective on 7/1/07 after a 6-month delayed effective date. The department and the council will be monitoring the international code changes through the International Code Council (ICC) process. The ICC web site to view the code change proposals and the justifications for the proposals is www.iccsafe.org/. The Wisconsin modifications will be looked at to determine if they are still needed. Issues decided and recommended by this council will be forwarded to the umbrella councils for review before proposed rules are drafted and reviewed by this council. 4. Review Summaries of Revisions Under the 2003 IMC and IFGC, and 2004 Supplement. The following 4 summary tables previously sent to all council members were discussed: 2003 IMC Revisions, 2004 IMC Revisions Supplement, 2003 IFGC Revisions, and 2004 IFGC Revisions. The 2003 revisions tables indicate the changes from the 2000 editions as shown with the lines in the margins of the 2003 editions. The 2004 revisions tables indicate the changes as compared to the 2003 editions. The council was asked to review these revisions tables for discussion at the next meeting relative to concerns with the changes listed in the tables. The council briefly discussed the NFPA 54 Comparison table previously sent to all members. This table indicates the changes in the 2002 edition as compared to the 1999 edition of NFPA 54 - National Fuel Gas Code. The 2002 edition is adopted in the department's gas systems code, chapter Comm 40, and the building code needs to adopt the same edition. The council requested copies of the 2002 edition of the NFPA 54 standard. (Copies of the relevant parts of the NFPA 54 standard are included with this report.) 5. Review IMC and IFGC and Wisconsin Modifications. Copies were distributed of the table titled International Mechanical Code Wisconsin Modifications. For the HVAC technical requirements in chapter Comm 64, this table shows the Wisconsin Modification, Justification for Change, and the corresponding IMC 2003/2004 provisions, if any. Under the Comm 64.0401(1) Wisconsin modification, the council discussed ventilation. The IMC allows natural or mechanical ventilation, whereas the Wisconsin modification limits natural ventilation. The council discussed the use of engineered systems to allow natural ventilation in certain situations, and support for this approach was expressed. It was noted that the entire Table 403 needs to be looked at, and that we may want to wait to see what the IMC contains next year for the 2006 code. Another issue discussed was under Comm 64.0605(4) relating to HVAC preheat coils. The Wisconsin modification created an exception for snow melting coils, but it was questioned as to what rule requires the filter for this scenario. The council was asked to Email suggestions for issues to discuss at the next meeting to Jim Quast at jquast@commerce.state.wi.us. Some major areas of concern mentioned were dampers, ventilation, and kitchen hoods. 6. Adjournment/Next Meeting. The next meeting was scheduled for Thursday, January 6, 2005, beginning at 9:30 a.m. in Room 3B.
