Welcome, introductions, housekeeping and review agenda
Jim Smith opened the meeting with introductions and thanking everyone for their time. The agenda for the current meeting was accepted as presented.

Review Council scope and purpose
Jim Smith stated the council’s purpose to review the changes in the 2009 Energy Code and the Wisconsin modifications to that code.

Review previous meeting’s progress report
Gerald Schulz moved to accept the progress report of the February 26, 2007, meeting, and Dave Osborne seconded. The motion passed.

Elect Chairperson
Dave Osborne nominated Ross DePaola, and Gerald Schulz seconded. The motion passed. The council determined that a vice-chair was not needed.

Review text of the Wisconsin Commercial Building Code Energy Conservation Advisory Council Workbook
Ross DePaola started the discussion with a brief overview of the international codes. The Council discussed the following:
- 101.4.2: Historic Buildings: Additions, but not maintenance, are subject to the new code.
- 101.4.3: Exceptions should be moved to Comm 61, but they would not be in the Energy Code (Comm 63). The Department of Commerce staff will clean up the locations of the code, especially the administrative provisions (Comm 61).
- 101.5.2 (2): Conditioned spaces in multi-use buildings, especially basement garages, are kept at approximately 45 degrees, but first floor retail is kept at approximately 68 degrees, which can cause problems.
- Part II of the I-Code will go to Comm 61: Administration and Enforcement.
- 303.1.4: It was suggested the new reference would only apply to home insulations because of the title of the reference and language in the overview and that commercial insulations are to be limited to those found in ASTM. It was explained that because the code itself referenced that CFR and did not incorporate any such limitation, it was likely intended to be accepted for all insulations, whether installed on homes or commercial buildings.
- 401.3: Certificate: Wisconsin does not require a certificate, but Table 402.1.1 has requirements for R-value certificate.
- 402.2.1: The modification (that one cannot use the reduction for the new U-value approach) relating to ceilings with attic spaces was discussed and included a conversation about how the reduced R value (where it states R-30 is "deemed to satisfy" where R-38 is required and also that R-38 can be used where R-49 is required) provisions that were not changed are applied. 402.4.2.1 and .2: Testing option and Visual inspection option: the council may recommend deleting reference to a code official. Questions arose such as "How did one comply with the code: test or visual?" "Is Wisconsin going to require this?" "What cost will be added?" The council needs to review this further.
- 403.1.1: Programmable thermostat: Do we want to expand it to include boiler systems?
- 403.2.1.: Ducts: Wisconsin’s code requires flexible R-4 insulation.
- 403.2.2 1.: Is this requirement viable? Does Wisconsin want to keep it? Would it require a third-party test? There are issues of square footage of floor space versus square footage of duct work.
- 403.8: Snow melt system controls: Wisconsin has repealed the no heated sidewalk statute if the system is controlled/energized within a commercial building.
- 405.2: Add a note in the building envelope and Addendum “G”
- 405.4.1: Compliance software tools: Is it really used in residential building?
- 405.5.2: Have the performance check computer programs been updated (it’s optional)?
- Table 502.2(1): Climate zone 6: is the information in the row “below grade wall” accurate? Check the errata.
- 502.4.5: Outdoor air intakes and exhaust opening: maybe remove the exception.
- 503.2.5.1: Demand controlled ventilation: Consider the use of economizers.
503.2.11: Issue for the new smoking ban.
503.3.1(1) footnote a. Does this make sense? A clarification may be needed.

Review text of the Wisconsin modifications from the Current Wisconsin Commercial Building Code, Chapter Comm 63
Jim Smith will condense the information and send it to the Council.

Assign homework
The council was instructed to re-review all the information and share information with those they represent and get their feedback. Feedback and any Wisconsin modifications that are being proposed are to be provided in writing to Commerce staff by September 15, 2009.

Set next meeting and adjourn
The next meeting is scheduled for Tuesday, October 6, 2009, from 9:00 AM to 2:00 PM, at the City of Madison Fire Station #11 - Conference Room.

Questions may be directed to Jim Smith, jim.smith@wisconsin.gov, 608-266-0251.

Monday, February 26, 2007, 9:30 a.m. to 1:30 p.m., Department of Commerce 201 W. Washington Ave., Room 3C, Madison, Wisconsin

Council Member Attendance: Jeffrey Boldt - P; Dan Dehnert - P; Ross DePaola - P; Kevin Lichtfuss - P; Dave Osborne - P; Gerald Schulz - A; Harry Sulzer - P; Bob Wiedenhoefer - P.

Guests: Norman Bair, state Department of Administration, Division of Energy; Tim Semmann, Wisconsin Builders Association

Commerce Staff: Jim Quast, Jim Smith, Bob DuPont, Randy Dahmen, Diane Meredith.

1. Welcome and introductions
Jim Quast opened the meeting with introductions. The progress report from the previous meeting dated November 16, 2005 and the agenda for the current meeting were accepted as presented.

2. Division Updates
The Division received approximately 260 public hearing comments on the proposed changes to update the Wisconsin Commercial Building Code (WCBC). The majority of the hearing comments related to the requirement that sprinklers be installed in all multifamily housing, and the remaining comments related to energy, mechanical and building technical requirements. The anticipated effective date of the revised WCBC is late summer or early fall.

3. Discussion of Public Hearing Comments/Responses
The hearing comments received relative to the International Energy Conservation Code (IECC) and the WCBC were distributed and the following discussions and recommendations were offered:

IECC section 505.5.1.4: A Wisconsin modification will be created to recognize the use of a current limiting device similar to California Title 24 relative to calculating the wattage loads for track lighting.

Comm 63.0505 (2) (b): The definition of “effective aperture” will be included under the code.

IECC section 505.2.2.1: It was suggested a Wisconsin modification be developed to ensure the ASHRAE 90.1 standard has a similar requirement for dual switching as required under the IECC. Under the proposed public hearing draft section Comm 63.0501 (4), dual switching is already required even if the ASHRAE method is followed.

Comm 630505: Additional lighting exceptions regarding the total connecting lighting power will be included to reflect the proposed changes for the 2009 edition of the IECC.

IECC chapter 4: The suggestion to limit the amount of glazing or window area restrictions will not be included since the federal Department of Energy (DOE) study concluded the elimination of the window restriction will not have a significant impact on energy use.

IECC 63.0503 (7) (b) and Table 63.0503: The council members discussed the use of economizers and whether a split-system should be considered a complex system as opposed to a simple system as currently considered under the IECC. A recommendation was made by the council to modify Table 63.0503 to include split systems and groundwater source cooling systems under the complex systems, which will require economizers on cooling systems greater than 54,000 Btu/h regardless of the occupancy.

Comm 63.0506: The code currently recognizes the use of the REScheck computer program for demonstrating that the building envelope complies with the code; however, the use of COMcheck-EZ is not recognized under IECC chapter 5. An informational note will be added to the code under s. Comm 63.0506 to recognize the use of COMcheck-EZ computer program.

IECC Table 503.2.8: A comment was received indicating the code fails to define the temperatures at which steam, hot water, chilled water, brine or refrigerant are to be recognized. It was decided the temperatures could be determined through the specified exceptions and standard dictionary definitions, so no code change will be necessary.

IECC 505.6: A comment suggested the current code clearly identifies how compliance can be achieved for interior lighting, but does not include the same language for exterior lighting. It was recommended an amendment be included for exterior lighting for enforcement purposes. However, it was noted the IECC provisions and the ASHRAE provisions are basically the same and compliance with IECC 505.6 can be achieved through interpretation of terms used in the code, such as, “densities permitted.”

The council members discussed the topic of ventilation under the International Mechanical Code (IMC), where the IMC typically requires 15-20 cfm/person of outside air for ventilation and recognizes natural ventilation for all occupancies, as compared to the WCBC requiring 7.5 cfm/person, and mechanical ventilation for most occupancies. The following comments and concerns were raised during the council’s discussion on the use of natural ventilation:
- Some criticism has been received that the current level of outside air (7.5 cfm/person) may be contributing to poor air quality, especially in schools.
- The reason Wisconsin kept the lower amount of outside air per person was for an energy conservation purpose and it was established using the minimum square footage per person based on occupancy.
- It was suggested that currently there are better energy recovery systems available that were not as readily available when the 7.5 cfm/person requirement was developed.
- There was concern raised that a building designed using all natural ventilation may create other problems, including increased humidity and extra energy use.
- Some felt that natural ventilation may work in some small occupied buildings or spaces; however, it may not work in all buildings and it would be better to mandate only a certain percentage of natural ventilation in certain buildings.
- It was noted that if all natural ventilation is provided, it would be difficult to satisfy the overall needs of the customers, who typically are looking for a more controlled environment, which would be better achieved through mechanical ventilation.
- It was noted the Department needs to justify why a Wisconsin modification is needed that is different from the IMC. It was explained the HVAC Code Council will be meeting on Wednesday, February 28th to discuss this issue as well.

4. Adjournment and update on future meetings.
It was announced that the CBCC/MDCC meeting will be meeting on Tuesday, March 27, 2007 to discuss the hearing comments and agency responses. The meeting, starting at 9:30 am, will be held at the Holiday Inn-Madison East located at 3841 East Washington Ave., in Madison. Members from this council are welcome to attend as visitors.

Questions may be directed to Jim Quast, Program Manager, 608-266-9292, jquast@commerce.state.wi.us.

Division Updates:
Jim Quast explained the Commercial Building Code Council (CBCC) and the Multifamily Dwelling Code Council (MDCC) will be meeting on December 8 to receive updates from the Energy, HVAC, Alterations and Change of Occupancy, and Fire Safety and Protection Systems Specialty Councils. The goal of the Division is to hold public hearings in the spring of 2006 on the proposed changes to the Wisconsin Commercial Building Code (WCBC) for incorporation of the 2006 editions of the ICC codes. The anticipated effective date of the revised WCBC is early 2007. Jim noted he hoped that by the end of this Energy Council meeting that there would be a
recommendation to proceed to public hearings.
Jim noted the following specific updates:
- Erosion control draft is being finalized for public hearings.
- Senate Bill 325 has been introduced that relates to improving indoor environmental quality in public schools. Under the bill a special committee may be formed in the Department to address several aspects of the bill, including rule development.
- Legislation is being proposed that would require certain installers, such as elevator and electrical, to be state-licensed. There is also some talk of including licensing of building contractors.
- Legislation requiring sprinklering of private university high-rise housing, sororities and fraternities retroactively passed and will be phased in over a certain number of years.
- Energy Policy Act has created tax credits for home builders who can demonstrate their homes are 50 percent better than the International Energy Conservation Code (IECC).
Review of Final Actions for changes to the IECC
Jim Quast distributed the challenges to the IECC 2004/2005 change proposals and a summary of these changes. Of the changes proposed, the following major changes were noted and the recommendations made:
- IECC Table 402.1: The thermal envelope insulation value for “wood frame walls” was revised to R-19 or R-13 (cavity insulation) + 5 (insulated sheathing) for Zone 6. This change was to correct an IECC/IRC inconsistency by using Department of Energy’s (DOE) original R-values for wood frame walls in the IECC.
- The members discussed whether the earlier IECC wood frame wall U-factors of R-21 or R-19 should be maintained and the following motion was made: Motion was made and seconded to maintain the requirements under the 2004 Supplement, which included higher U-factors for wood frame walls as specified under IECC Table 402. The motion failed by a vote of 6 to 1.
- Ross DePaloa also noted there was an earlier decision made by the Council at the May 18 meeting to include a footnote under the fenestration column that would limit the fenestration to wall ratio to 25 percent, and to include a footnote under the sky-light column to limit the fenestration to 10 percent of the roof area. Ross did not see this change in the proposed draft and it was explained the inclusion of these modifications are being discussed with Division management.
- IECC section 803.2.6 and Table 803.2.6 (1): A provision, which is consistent with ASHRAE 90.1, was added to address over-pressurization during economizer operation, and the trigger for requiring economizers was lowered to less than 54,000 Btu/hr for Zone 6B. The members agreed that Table Comm 63.0803 should be modified to require economizers on all simple cooling systems at less than 33,000 Btu/hr and complex cooling systems to less than 54,000 Btu/hr.
- IECC section 803.3.3.4: Revised the language to require motorized dampers on all outdoor air supply and exhaust ducts that will automatically shut when the system or a space is not used, and to permit gravity dampers only under certain conditions. The members had a lengthy discussion, which resulted in creating Comm 63.0803(6)(b), to permit gravity dampers only when the outside exhaust airflows are 300 cfm or less.
- IECC section 805.2.2: The modifications relating to an occupant override for lighting controls were clarified, and the lighting power compliance provisions were simplified to be consistent with ASHRAE 90.1. It was noted that IECC provisions and ASHRAE 90.1 provisions are not exactly the same. The members discussed whether the lighting controls should be the same for both ASHRAE 90.1 and the IECC and the following motion was made: A motion was made and seconded to create a Wisconsin modification that would require consistent application of the dual lighting controls under IECC section 805.2.2.1 for both ASHRAE 90.1 and the IECC. The motion carried by unanimous vote.
- IECC section 805.5.2: The lighting power compliance provisions were simplified to be consistent with ASHRAE 90.1. However, ASHRAE 90.1 section 9.2.2.3 includes additional exceptions, which should also apply if the IECC is used for compliance. The members also discussed that under current Comm 63.1045 3)(a) there are additional exceptions, such as lighting for amusement and attraction areas in theme parks, that are not included under the IECC or ASHRAE 90.1 and should they be included as Wisconsin modifications. The following motion was made: Motion was made and seconded to create a Wisconsin modification that would require the exceptions under ASHRAE 90.1 section 9.2.2.3 to apply when the ICC is used. The motion passed by unanimous vote.
- Comm 63.0805 (3): The members recommended the lighting density as used under the lighting control requirements be changed to 0.8 W/ft2.
Use of the International Existing Buildings Code (IEBC) and application of energy requirements
Jim Quast updated the members on the proposed adoption of the IEBC, which includes energy requirements. He distributed excerpts from the IEBC relating to energy and explained that alterations and additions to existing buildings would be required to comply with the requirements for new construction as specified under the IECC. It was noted that these requirements are consistent with ASHRAE 90.1 with regards to repair and replacement of equipment.
Ventilation Controls
Members discussed whether the code should require ventilation controls that would operate to reflect the varying occupant load for large multi-purpose areas such as high school gymnasiums. This issue was discussed by the HVAC Specialty Council and was not accepted. The members discussed that this was an energy conservation issue but some indicated the code already provides the flexibility to reduce the ventilation to areas when the occupant load varies. It was decided the members were to send Jim information on any proposed language. Jim noted this recommendation would need to be reviewed by management within the Division before any changes are proposed.
Council Recommendation
The members unanimously recommended the adoption of the 2006 IECC with the proposed Wisconsin modifications and these modifications should be included in the public hearing rule package for Comm 61 to 66.
Next Meeting: This Council will not meet again until after public hearings are held in the spring of 2006. The CBCC/MDCC meeting will be on Thursday, December 8, 2005 to review all of the proposals from the Division Specialty Councils. The meeting, starting at 9:30 am, will be held at the Holiday Inn-Madison East located at 3841 East Washington Ave., in Madison. Bob Wiedenhoefer as chairperson is invited to come to CBCC/MDCC meeting to represent the Energy Specialty Council, if he so desires. Other members are welcome to attend as visitors.

Bob Wiedenhoefer asked for a review of the agenda and the progress report from the previous meeting; both were accepted as written. However, it was requested that a discussion on economizers be included on the agenda for the next Council meeting.

Division Updates
Jim Quast explained the Specialty Councils are meeting to discuss the ICC changes that may become part of the 2006 ICC codes and to review current Wisconsin based modifications for relevancy. The Umbrella Councils will be meeting on October 27th and December 8th to receive updates on the Specialty Councils recommendations. The goal of the Division is to hold public hearings in the spring of 2006 on the proposed changes to the Wisconsin Commercial Building Code (WCBC) for incorporation of the 2006 editions of the ICC codes. date of the revised WCBC is early 2007.

Presentation from Energy Cooperatives
Bob DuPont and Jim Quast explained the Energy Conservation Code Council, which is comprised of energy experts, has been asked to listen to the concerns the Wisconsin Electric Cooperatives have with certain Uniform Dwelling Code (UDC) requirements relating to energy conservation and to provide their advice.

Dave Jenkins from the Wisconsin Federation of Cooperatives and Jan Stranz from the Oconto Electrical Cooperative addressed the Council and indicated they have specific concerns with the current requirements for electrically heated homes. They indicated the purpose of the presentation was to ask that the UDC be analyzed to provide fair treatment of advanced electric heating options, such as geothermal heat pumps.

The following points and issues were stated during their presentation:
- Explained the super-insulation requirement for electrically heated homes was based on state laws that were created in 1983. Indicated the UDC currently requires insulation requirements of R50 in the ceiling and R12.5 in the walls of electrically heated homes.
- Identified a concern that the appliance credits available under the UDC work with high efficiency gas furnaces but do not work properly when heat pumps or radiant heat are used.
- Asked the REScheck and WIScheck software packages be reviewed to correct the deficiencies that exist when other heat sources, such as heat pumps, ground source heat pumps, or dual fuel systems are used.
- Presented fuel cost comparisons for a sample home using propane gas and one using ground source heat pump. The ground source heat pump system would have fuel costs considerably less than the propane gas heat system.
- Indicated that in rural areas of Wisconsin, natural gas is often unavailable, leaving only electrical, propane, fuel oil or wood as their choices.
- Suggested that all heating sources used in homes should have the same insulation levels.

The Council members were generally not in favor of reducing the amount of insulation required in homes that use electric resistance heating during peak hours. However, they indicated that the code should be modified to recognize a home that uses ground source electric heat pumps. The thermal envelope provisions for this type of heat pump should reflect values similar to non-electrically heated homes. It was noted that REM/Rate is a software program that recognizes the other heat sources; however, most UDC inspectors use REScheck or WIScheck, which is where the problem exists. Leroy Stublaski, UDC consultant, feels the code under s. Comm 22.21 (3) (d) already recognizes using other heat sources but agrees that the programs used to verify compliance with the requirements could be improved. It was suggested that training should be available to the inspectors so they of aware of other acceptable software programs and methods besides the REScheck and WIScheck software programs.

Use of the International Residential Code (IRC) for energy conservation requirements under the UDC
The members discussed using the energy conservation requirements from the IRC, which is essentially using the International Energy Conservation Code(IECC). There was some concern on the availability of this code to the general users of the code, and that the IRC/IECC does not address an overall U-value for a dwelling. They also wanted to know how the code would apply to the concerns discussed earlier relating to the use of other heating sources, and how REScheck would work with the IECC.

Bob DuPont asked which members of this Council would be interested to study energy issues under the UDC. The following people offered to be part of the work group to study the UDC issues: Ross DePaola, Dave Osborne, Harry Sulzer, Bob Wiedenhoefer

Homework assignments: Ross DePaola will check on the REScheck program and its use in the IRC.

Next meeting: The next meeting of the Energy Conservation Code Council is scheduled for Tuesday, November 16th to discuss potential changes to the WCBC for incorporation of the 2006 IECC.

Council Member Attendance: Jeffrey Boldt P; Dan Dehnert P; Ross DePaola P; Tim Kritter Ex; Kevin Lichtfuss A; Dave Osborne P; Gerald Schulz Ex; Harry Sulzer P; Bob Wiedenhoefer P

Guests:Jim Boullion, AGC of Wisconsin; Scott Olsen, MGE

Commerce Staff: Jim Quast, Program Manager; Diane Meredith, Code Consultant; John Spalding, Integrated Services

Welcome and introductions: Bob Wiedenhoefer opened the meeting with a review of the agenda and the progress report from the previous meeting, both were accepted as written.

Division Updates Jim Quast reported Kimberly Walker, Division administrator, is leaving Safety and Buildings to take the position of Division Administrator for the Division of Energy in the Department of Administration. Kimberly’s last day with the Division is May 27th.

Jim noted that the HVAC Advisory Code Council would be meeting on June 14th to discuss ventilation issues. Jim explained the one-and two-family dwelling code inspection program of contracting with outside providers and this model might be reviewed for use with commercial buildings in the future. Members expressed concern that there must be a monitoring system in place so consistency in application and enforcement can be achieved when outside providers are used. Jim noted that consistency is a problem with the current enforcement process, and that monitoring is necessary with any enforcement system.

John Spalding reported the plan reviews are keeping within the target timeframes. He also indicated the Web scheduling system will start in early July and after the system is stabilized, the fax scheduling would be eliminated.

Discussion of Current Wisconsin Modifications under Comm 63 subchapter III Jim Quast explained that after today’s meeting, staff members would start work on a proposed hearing draft with the modifications proposed to the IECC that would be available in late summer. The group would still need to review the IECC 2004/2005 proposed changes and the final ICC determinations would be decided at their meetings in fall.

The following code sections were discussed and the Council recommendations are noted:

1. Comm 63.0001 to 63.0004 Purpose, scope and application
The administration and enforcement requirements under IECC chapter 1 will be reviewed by staff for potential placement under chapter Comm 61, which is the general chapter on administration and enforcement for the entire Wisconsin Commercial Building Code (WCBC). Jim noted the IECC is organized and formatted such that the general application section contains some specific technical requirements that should probably be maintained under chapter Comm 63.

2. Comm 63.1050 Lighting Controls

The members discussed the lighting comparison tables prepared by Jim Quast, which included a comparison of the current Comm 63 requirements to the California 2005 code, the IECC and the ASHRAE 90.1 standard. Ross DePaola explained the purpose behind the current lighting control requirements under Comm 63 is to provide designers with flexibility in lighting design by allowing trade-off for lighting levels. The IECC and ASHRAE 90.1 standard have decreased the lighting levels to save energy and some members felt the current control requirements would provide the flexibility for designers to allow increased lighting in some areas when lighting controls are provided. Some members also expressed the desire for the code providing some type of daylighting incentives.

The members proposed the following requirements for lighting:

Use the IECC or ASHRAE 90.1 standard for lighting requirements with the following modifications required if either model is used:

- Maintain the lighting control requirements for dual switching specified under Comm 63.1050 (2) (a)
- Maintain the daylighting requirements specified under Comm 63.1050 (3)
(Staff to research whether the “daylighting area” definition parameters in conjunction with Comm 63.1050 (3) create “barriers” for deep-daylit spaces.)
- Limit one parameter for retail lighting for displays to 50 percent of the floor area. (Note: Monitor IECC proposed revisions #99-04/05 and #101-04/05.)

3. IECC section 803 relating to minimum equipment efficiencies

It was reported that the Department of Energy (DOE) regulations relating to minimum efficiency requirements for the manufacture of mechanical equipment are to take effect January 23, 2006. Staff members will monitor the IECC changes to see that the new ratings are consistent with these DOE regulations.

4. Table 63.0803 Economizer Requirements

It was discussed that economizers should be required on all rooftop units that have a capacity greater than 3-ton capacity. The energy savings by providing economizers, especially on all rooftop units, would offset the cost to provide the economizers. It was proposed to change the Table 63.0803, 2nd line/2nd column to read:

“Economizers on all cooling systems 33,000 Btu/hr.”

5. IECC Table 402.1 relating to fenestration

A concern was raised relating to the amount of fenestration permitted under IECC Table 402.1. It was discussed the amount of fenestration is not limited under the IECC and to maintain energy conservation savings the following motion was made:

A motion was made and seconded to:
- create footnote h under IECC Table 402.1, column “fenestration U-factor” that reads:
h. The fenestration shall not exceed 25% of window to wall ratio

- create footnote i. under “Skylight U-factor” that reads:
i. The fenestration shall not exceed 10% of the roof area.

The motion passed by unanimous vote.

Homework assignments The following assignment was given for completion by the next meeting:

All members are to review the IECC 2004/2005 proposed changes. The IECC Committee decisions to the 20004/2005 changes were distributed to the members earlier. Staff will prepare a proposed draft of modifications that will be included when the 2006 IECC is adopted.

Next meeting The next meeting will be scheduled sometime in late summer or early fall. The proposed draft of changes to the IECC will be mailed to the members for their consideration prior to the next meeting.

Tuesday, April 12, 2005, 9:30 a.m. to 2 p.m., Department of Safety and Professional Services, 201 W. Washington Ave., Room 3B, Madison, Wisconsin

Council member attendance: Jeffrey Boldt P; Dan Dehnert P; Ross DePaola P; Tim Kritter Ex; Kevin Lichtfuss A; Dave Osborne P; Gerald Schulz P; Harry Sulzer P; Bob Wiedenhoefer Pu

Guests: Don Hynek, Wisconsin DOA-Division of Energy; Scott Olsen, Madison Gas and Electric

Commerce staff: Jim Quast, Program Manager; Diane Meredith, Code Consultant; John Spalding, Section Chief

Welcome and introductions
Jim Quast opened the meeting with a review of the agenda and the progress report from the previous meeting, both were accepted as written.

Division Updates Jim Quast noted there were no updates to report and indicated that plan review processes were within the targeted timeframes.

Discussion of Current Wisconsin Modifications under Comm 63 subchapter III Jim explained that under the IECC designers are given a choice model for commercial buildings to use either IECC chapter 8 or the referenced ASHRAE 90.1 standard. The requirements under Comm 63, Subchapter III replaced the referenced 1989 edition of the AHSRAE 990.1 standard. The current requirements of Comm 63, Subchapter III were based upon developing work for the 1999 ASHRAE 90.1 standard. The IECC 2006 edition will reference the 2004 edition of the ASHRAE 90.1 standard. Jim explained that it is the Division’s premise that the separate Comm 63, Subchapter III is no longer necessary and that any necessary Wisconsin requirement from the subchapter can be retained and relocated as a modification to the IECC.

The following code sections were discussed and the Council recommendations are noted:

- Comm 63.1027 Zone Controls and 63.1028 Humidity Controls
Delete these requirements under this chapter and defer them to the HVAC Council.

- Comm 63.1029 Insulation, materials and construction
Delete these requirements since they are covered under ASHRAE 90.1 standard.

- Comm 63.1030 Hydronic System Controls
Delete this requirement since it just cross-references the IECC requirement.

- Comm 63.1032 Motor Efficiencies
The members discussed whether all motor efficiencies are already required to comply with the Energy Policy Act (EPAct) of 1992, which would not be different from the ASHRAE 90.1 Table. Don Hynek from DOA offered to provide staff with the EPAct information on the motor efficiencies. If motor efficiency is a minimum federal requirement, it was suggested to put an informational note in Comm 63 and include the EPAct Table in the Appendix.

- Comm 63.1060 Nondepletable Energy Source and 63.1070 System Analysis Design
Delete these requirements since they are covered in the ASHRAE 90.1 standard.

- Comm 63.1040 to 63.1050 Lighting Requirements
Ross DePaola distributed information from a study group on the lighting requirements and indicated there are inconsistencies between the IECC and the ASHRAE 90.1 standard and recommended that the lighting requirements remain as Wisconsin modifications and suggested reprinting tables in the IECC and ASHRAE 90.1 standard. The recommendations included:

- Maintain the current Comm 63 requirements relating to lighting controls, lighting adjustment factors, which were based upon California’s energy code
- Retain and modify the current Comm 63 Table with lighting control credits
- Revise the current interior lighting power budget requirements
- Modify the daylighting controls
- Eliminate the current Complete Building Method relating to lighting power allowance
- Eliminate the Area Factor Tables under Comm 63.1049 and adopt the IECC Tables for building area method
- Adopt ASHRAE 90.1 requirements for exterior lighting power and consider adopting requirements mandating Pulse-Start ballasts for HID fixtures.
- Reduce exit light watts to match IECC and ASHRAE 90.1

Jim Quast explained again that the IECC will be adopted by reference as the base standards and the need to reprint Tables or requirements from the IECC or ASHRAE 90.1 is not necessary. Even though some members felt that it would be easier to have all of the lighting requirements in one area, others felt that the number of Wisconsin modifications should be kept to a minimum when using IECC or ASHRAE 90.1. It was also noted that the IECC together with the ASHRAE 90.1 standard provides flexibility in design without minimizing the energy conservation of a building. Also noted was that IECC/ASHRAE cover the same matters as the current Wisconsin lighting requirements other than the lighting power adjustment alternatives and that the 2006 IEEC/ASHRAE power densities reflect greater energy savings.

It was decided that staff members would do a comparison of the lighting controls that are under Comm 63-Subchapter III, IECC and ASHRAE 90.1 and have it available for the next meeting. The members did agree that the IECC should be used without reprinting all of the lighting requirements but identified the following issues to be discussed at the next meeting:
- Comm 63.1045 relating to the calculation of interior lighting power
- Comm 63.1045 (2), Table 1045 and Comm 63.1051
- Comm 63.1050 should be reviewed to identify any specific requirements for retention

Review of 2004 ICC Changes

The members reviewed the changes contained under the 2004 IECC Supplement and identified the following:

- Delete IECC section 401.3 relating to certificate requirements to be included at the electrical panels for low-rise residential buildings. It was felt that in most cases the certificate requirement would not benefit the tenants in residential buildings.
- Ross was concerned that residential buildings could use an all glass wall under IECC section 402.3 because there is no overall U-value. However, the members recommended maintaining the IECC section 402.3 relating to fenestration.
- As determined earlier, IECC section 402.5 relating to moisture control will be modified.
- Noted that any changes made to lighting controls will also require changes under IECC section 802.1 relating to general building envelope requirements.
- IECC section 803.2.5.1 relating to energy recovery ventilation systems will be reviewed to see whether the requirements overlap with the economizer requirements.

Homework assignments The following assignments were given for completion by the next meeting:
- Staff members will contact Don Hynek from DOA for information on the EPAct requirements.
- Staff members will prepare a comparison on lighting issues.
- All members are to review the IECC 2004/2005 proposed changes. The IECC decisions on the proposals were distributed.

Next meeting The next meeting has been scheduled for Wednesday, May 18, 2005 in conference room #3B in the Thompson Commerce Center, 201 W. Washington Ave., in Madison.

Tuesday, March 15, 2005, 9:30 a.m. - 2 p.m., Thompson Commerce Center, Room 3B, 201 W. Washington Ave., Madison, Wisconsin

Council Memeber Attednace: Jeffrey Boldt Ex; Dan Dehnert Ex; Ross DePaola P; Tim Kritter A; Kevin Lichtfuss P; Dave Osborne P; Gerald Shulz Ex; Harry Sulzer P; Bob Wiedenhoefer P

Guests: Don Hynek, Wisconsin DOA-Division of Energy; Scott Olsen, MGE

Department of Safety and Professional Services Staff: Jim Quast, Diane Meredith, John Spalding,

Welcome and introductions: Bob Wiedenhoefer opened the meeting with a round of introductions. The progress report from the previous meeting and the meeting agenda were accepted as presented. (Please note that Dan Dehnert should be been marked excused rather than absent from the 2/08/05 meeting.)

Division Updates

Jim Quast noted the ICC organization has included the Wisconsin Enrolled Commercial Building Code (WECBC) on their Web site for reviewing. This ICC decision to provide this on their Web site may have resulted from a federal Court decision in Texas that ruled once a state or municipality adopts a model code, the copyright restrictions do not apply. It was noted that this federal Court decision would only apply to the federal Court district where the decision was made.

Jim explained the Division of Safety and Buildings’ was asked to develop a plan for how it would reduce its budget by 10-percent spending authority and 10-percent staffing positions, if required to do so. The staffing positions in the Division of Safety and Buildings would need to be reduced by approximately 21 people. Most of these cuts would be in vacant positions. John Spalding indicated that currently the Division has 14 inspectors who perform commercial inspections.

Jim indicated that in accordance with s. 101.651, Stats., the Uniform Dwelling Code, as of January 1, 2005, is being enforced in every community. The law required that where communities do not have enforcement or inspection authority for one-and two-family dwellings, the state must provide the inspection services. The Department has contracted with 24 inspector groups to perform these inspection requests. Jim also noted that the UDC inspection process is not the same for commercial buildings, which does not mandate an inspection before an occupancy permit is issued.

Discussion of Current Wisconsin Modifications under Comm 63 subchapter III
Jim Quast explained to the members that it is the Division’s recommendation to eliminate all of the requirements under Comm 63, Subchapter III since these requirements were only included because the ASHRAE 90.1 standard-1989 version was referenced under the 2000 edition of the IECC. The requirements in Comm 63, Subchapter III were considered improvements over the 1989 edition of AHSRAE 90.1 standard; however, since a newer version of ASHRAE 90.1 standard, most likely the 2004 edition, will be referenced under the 2006 IECC, the current requirements could be eliminated.

The following code sections were discussed and the Council recommendations are noted:

1. Comm 63.1001 Application
Hold the final decision on the requirements under Comm 63.1001 for discussion with the general application and enforcement requirements.

2. Comm 63.1005 Definitions

Delete the definition section and include any unique definitions under IECC section 200.

3. Comm 63.1010 Exempt Buildings

The requirements under Comm 63.1010 will be discussed with the general application and enforcement requirements.

4. Comm 63.1011 Air Leakage

Delete the requirements relating to air leakage since they are covered under IECC sections 802.

5. Comm 63.1012 Daylight Credits for Skylights

Delete the requirements relating to daylight credits for skylights since the current requirements are not substantive for application.

6. Comm 63.1014 Building Envelope Thermal Performance

Delete the requirements relating to building envelopes since these requirements are covered under IECC section 806.

7. Comm 63.1015 Component Standards Option

Delete this section relating to component standards for building-envelope thermal performance since these requirements are covered under IECC section 806.

8. Comm 63.1016 System Standards Option

Delete this section relating to system standards for building-envelope thermal performance since these requirements are covered under IECC section 806.

9. Comm 63.1017 Design Criteria

Delete this section relating to system standards for thermal performance values for the exterior envelope for certain buildings since these requirements are covered under IECC section 802.

10. Comm 63.1018 Material Properties

Maintain the requirements under this section relating to test methods for determining thermal properties of materials.

11. Comm 63.1019 Required Calculation Procedures

Delete these prescriptive requirements relating to calculation procedures for thermal performance since the requirements under IECC section 801.2 are adequate.

12. Comm 63.1020 Minimum Equipment Efficiencies

Hold off on the final decision until more information is received relating to a federal law that requires a higher SEER efficiency rating than specified under the IECC. Don Hynek from DOA offered to provide a copy of the federal law to staff members.

13. Comm 63.1021 Field-Assembled Equipment and Components

Delete the requirement relating to component efficiencies since a similar requirement is covered under IECC section 102.

14. Comm 63.1022 Heat Pump Equipment Controls

Delete the requirements relating to heat pumps that are equipped with supplementary heaters since these requirements are already covered under IECC section 803.

15. Comm 63.1023 Load Calculations for Sizing and Comm 63.1024 System and Equipment Sizing

Hold the final decision on these requirements relating to sizing of systems and equipment since the requirements appear to overlap with requirements in Comm 64 relating to HVAC. The members are to review the requirements under IECC 803.2 and 803.3 for consistency with these rules.

16. Comm 63.1026 Temperature Controls and Comm 63.1027 Zone Controls

Delete these requirements relating to HVAC systems and control devices for temperatures and zone controls since these requirements are covered under IECC section 803.

Homework assignments The following assignments were given for completion by the next meeting:

- Staff members will contact Don Hynek from DOA for information on a federal law requiring a higher SEER efficiency rating.
- All members will identify any requirements besides the lighting requirements that may need to be retained from Comm 63.1028 to 63.1032, and Comm 63.1060 and 63.1070.
- Ross DePaola will share material on the lighting systems.
- All members are to review the IECC 2004 for any other issues that may need to be discussed.

Next meeting: The next meeting has been scheduled for Tuesday, April 12, 2005 in conference room #3B in the Thompson Commerce Center, 201 W. Washington Ave., in Madison.

Tuesday, February 8, 2005, 9:30 a.m. to 2 p.m., Thompson Commerce Center, Room #3B, 201 W. Washington Ave., Madison.

Welcome and introductions
Bob Wiedenhoefer opened the meeting with a round of introductions. The meeting summary from the previous meeting and the meeting agenda were accepted as presented.

Division Updates
Copies of the revised chapters Comm 61 to 65, Wisconsin Commercial Building Code, and the adopted copy of the rule changes, which contains the analysis of the rule changes, were distributed to the members. Jim Quast explained that insert pages containing the codes that have been modified are available on the Web site for use with the Wisconsin Enrolled Code. Jim also noted that the Wisconsin Enrolled Code is available for viewing at the International Code Council’s Web site: www.iccsafe.org.

Jim indicated that several of the specialty councils reviewing updates for the future adoption of the 2006 ICC codes are continuing their work. He noted that the HVAC Code Council would discuss ventilation issues, such as dampering and natural ventilation, at an upcoming meeting.

Jim reported that the WE Energies Building Code Collaborative has discussed daylighting issues and it is their belief that provisions necessitating daylighting, if any, would be better placed in the Building Code rather than the Energy Code. Some Council members felt the Building Code is to be a minimum code for energy conservation and should not become a design tool that restricts designers to only a few design options.

Presentation from Scott Olsen
Scot Olsen, who is an efficiency engineer from Madison Gas and Electric (MGE) identified the following energy issues for consideration by this Council.

1. Focus on outdoor air ventilation rate for large occupancy spaces where the occupant load changes.
2. Suggests adopting the IECC lighting power densities and maintain the separate controls for non-daylighting areas in a building. He also suggests maintaining occupancy sensors for daylighting spaces.
3. Provided a comparison chart supporting the savings that would be obtained for rooftop air conditioning and condensing units using the IECC-2003 code or the ASHRAE 90.1-2001 standard over the current energy code.
4. Suggests that natural ventilation not be restricted but allow it only with careful consideration. Some members felt that energy recovery is the only answer for use of natural ventilation.
5. Recommends that the Energy code ensures that modulation of air changes per hour of supply air be allowed.

Discussion of Current Wisconsin Modifications
The following code sections were discussed and the Council recommendations are noted:

Comm 63.0802 (2) Moisture Control
The members discussed whether foam insulation with a perm rating one 1 would also require a vapor retarder. It was noted that providing this type of insulation would not require the vapor retarder and that the code is written such that it would be acceptable without making a specific modification. It was suggested that the same modification be made to IECC 802.1.2 for commercial buildings as made under IECC 402.5 for residential buildings, which is to eliminate the words “not ventilated to allow moisture to escape.”

Comm 63.0802 (3) [IECC 802.2.4] Roof Assembly
Delete the modification since the members feel that the Wisconsin requirement is too vague and does not provide any improvements to the IECC requirements.

Comm 63.0802 (4) [IECC 802.3.2] Sealing of the Building Envelope
Delete the modification since recessed luminaries are specifically addressed under IEEC section 802.3.7.

Comm 63.0803 (1) [IECC 803.1] Electrical motors
It was suggested to contact people who would use these requirements to see whether the electric motor efficiencies are still needed. Jeff Boldt indicated that ASHRAE 90.1 standard may cover electric motor efficiencies. This item will be put on hold until the next meeting.

Comm 63.0803 (2) (a) [IECC 803.2.1.1] Simple HVAC Systems and Equipment
Keep the same Wisconsin modification, which permits the heating and cooling equipment to be oversized to the calculated load.

Comm 63.0803 (2) (b) [IECC 803.2.3.1] Temperature Controls
Retain the Wisconsin modification and the IECC exceptions. It was suggested to rewrite the entire requirement including the exceptions so the entire requirement text is in one place.

Comm 63.0803 (2) (c) [IECC 803.2.3.2] Humidity Controls
Delete the modification but request that this topic be discussed with the HVAC Council.

Comm 63.0803 (2) (d) [IECC 803.2.6] Cooling with outdoor air
Revise the current modification requiring economizer controls retaining basically the current triggers, but modifying IECC Table 803.2.6 (1) by adding zones 6A and 7. It was suggested to reprint the entire Table so all of the text is in one place.

Comm 63.0803 (2) (e) [IECC 803.2.7] Shutoff dampers
Maintain the modification that requires that automatic or gravity dampers be provided on all outdoor air intakes.

Comm 63.0803 (2) (f) [IECC 803.2.8] Duct and plenum insulation
Maintain current modification relating to the insulation of all supply ducts and return air ducts and plenums but change the R-7.5 insulation rating to R-8.

Comm 63.0803 (3) (a) [IECC 803.3.1.1] Equipment and system sizing
Maintain the Wisconsin modification, which permits the heating and cooling equipment to be oversized to the calculated load.

Comm 63.0803 (3) (b) [IECC 803.3.3.4] Shutoff damper controls
Maintain the modification but eliminate the word “gravity” since it is redundant with automatic dampers.

Comm 63.0803 (3) (c) [IECC 803.3.3.5] Economizers
Maintain the modification relating to economizers on fan systems and make it the same as proposed under IECC 803.2.6.

Comm 63.0803 (3) (d) [IECC 803.3.7] Piping Insulation
Delete Table 63.1029 relating to pipe insulation and cross-reference the requirements in the ASHRAE 90.1 standard, which contains all of the requirements currently contained under Table 63.1029.

Comm 63.0803 (3) (e) [IECC 803.3.8, 803.3.8.1 to 803.3.8.3] HVAC System Completion
Delete the current modification relating to balancing and documentation of HVAC systems and replace it with a requirement that states the IEEC requirement does not apply. This requirement is covered under the IMC.

Comm 63.0804 (1) [IECC 804.3] Temperature Controls
Maintain the current modification, which states that the IECC requirement relating to temperature controls is not included in Wisconsin.

Comm 63.0804 (2) [IECC 804.4] Heat Traps
Delete the current modification and change it to state that the IECC requirement relating to heat traps does not apply in Wisconsin. The members felt this requirement if used should go under the Plumbing Code.

Comm 63.0804 (3) [IECC 804.5] Plumbing Piping Insulation
Delete Table 63.1029 relating to pipe insulation and cross-reference the requirements in the ASHRAE 90.1 standard, which contains all of the requirements currently contained under Table 63.1029.

Comm 63.0805 [IECC 805] Lighting Systems
It was suggested that a subgroup be formed to study the lighting requirements. Ross DeDePaloa will take the lead on gathering information for consideration by this council.

Comm 63, Subchapter III [Comm 63.1001 to 63.1070] Building Design for Commercial Buildings
The council members by consensus feel that Comm 63, subchapter III, could be eliminated except for certain requirements relating to lighting. Members are to review the requirements in this subchapter and identify any other requirements besides lighting that may need to be retained.

Homework assignments
The following assignments were given for completion by the next meeting:
- Jeff Boldt will share a copy information from the ASHRAE 90.1 standard relating to plumbing and piping insulation, and also information on electric motors.
- Ross DePaola will share material on the lighting systems.

Welcome and introductions
Jim Quast opened the meeting with a round of introductions. Jim noted there would be a change in the agenda because Scott Olsen was unable to address the council and he would be invited to the next meeting, otherwise the agenda was approved as proposed. The progress report from the previous meeting was also approved as presented.

Election of Chairperson
Bob Wiedenhoeffer was elected chairperson for the council.

Division Updates
Jim reported that the miscellaneous update package to chapters Comm 61 to 65 would have an effective date of January 1, 2005. The council was provided excerpts from this rule package that related to chapter Comm 63. It was noted that chapter Comm 70, Historic Building Code, would also become effective on January 1, 2005.

Jim indicated that several of the specialty councils reviewing updates for the future adoption of the 2006 ICC codes have started their work. A new code council is in the process of being formed to review code material related to alteration or change of use to existing buildings. That council hopes to meet early next year.

Presentation from Todd Stuart
Todd Stuart, Policy Advisor to Senator Robert Cowles, along with Abby Vogen from the Wisconsin Energy Center presented material on energy issues the Senator’s office would like to see this council address. Todd explained Senator Cowles is the head of the legislative Energy Committee and he would like to see the Department’s Energy Council members discuss and consider including requirements for daylighting and solar water heating rather than creating legislation. The legislative Energy Committee is concerned with the increase in the cost of energy to the all citizens and would like to see Wisconsin keep up with current energy practices.

Todd noted that daylighting, which is a method to light buildings using natural light, is not a new method and many state buildings are already using cool daylighting. Abbey distributed a study concerning the potential energy savings using daylighting, and Todd also explained there are Wisconsin solar companies that provide customers with hot water at energy cost savings. While there may be other new technologies for consideration, the Senator’s office is only requesting that the daylighting and solar water heating concepts be explored for possible inclusion in chapter Comm 63.

Discussion of Current Wisconsin Modifications
The following code sections were discussed and the Council recommendations are noted:

Comm 63.0101 through 63.0107 Purpose, Scope, Application and Compliance
It was suggested that staff review the need for keeping the administration and enforcement requirements under chapter Comm 63 or whether there would be a benefit to move them to the chapter Comm 61, which contains all of the administration and enforcement requirements for the Wisconsin Commercial Building Code. Eliminate the terminology of “residential building, Type A-1” as used under Comm 63.004 (2) (b).

Comm 63.0202 Definition
Delete the definitions of “circulating system” since this term is no longer used in the IECC.
Staff members are to review the definition of “code official” to determine whether a global replacement of the term would be appropriate in chapter Comm 63 and the IECC.

Comm 63.0302 Weather Adjustments
Replace the term “code official” with “department” for who should determine the annual energy-usage calculation-tool.

Comm 63.0502 (1) [IECC 402.5] Moisture Control
Delete the current modification. Use the new IECC 402.5 requirement but eliminate the following wording in the 2nd sentence: “not ventilated to allow moisture to escape,” thereby requiring a vapor retarder in all situations.

Comm 63.0502 (2) Floors Over Unheated Spaces and Comm 63.0502 (3) Floors
Delete both of these modifications since the wording under the new IECC 402.5 is acceptable.

Comm 63.0503 (1) [IECC 403.6] Equipment Sizing
It was suggested that staff members research the ACCA manual that is ultimately referenced. This item will be held for further discussion.

Comm 63.0503 (2) (a) [IECC 403.3 and 403.4] Piping Insulation
The new IECC requirements appear to simplify the minimum insulation requirements; however, there is concern that using these new requirements may not achieve the current levels of energy savings. This item will be held for further discussion as there are proposed IECC revisions concerning this issue.

Comm 63.0503 (2) (b) [IECC 403.2] Duct Insulation
Delete the current modification. Hold off on proposing any modification to IECC 403.2 until the commercial requirements are discussed.

Comm 63.0503 (2) (c) and (d) [IECC 403.2.2] Sealing
Delete the current modifications since the new IECC 403.2.2 is acceptable.

Comm 63.0503 (2) (e) [IECC 403.5] Mechanical Ventilation
Maintain current modification relating to automatic dampers on outdoor air intakes.

Comm 63.0503 (2) (f) Balancing
Delete the current modification since it is covered under the International Mechanical Code (IMC)

Comm 63.0504 (1) Combination Service Water-heating and Space-heating Boilers
Delete the current modification since the subject is not addressed under the latest IECC edition.

Comm 63.0504 (2) [IECC 403.4] Pipe Insulation
This item will be held for further discussion.

Comm 63.0504 (3) Swimming Pools
Delete the current modification since they are no longer included under chapter 4 of the IECC.

Comm 63.0505 Lighting Power Budget
This item will be held for further discussion with all of the lighting issues.

Comm 63.0602 (1) [IECC 402.1 and Table 402.1] Floors over Outside Air
Delete the current modification since it is covered under the new IECC requirements.

Comm 63.0602 (2) Caulking, Sealants and Gasketing
Delete the current requirement since IECC chapter 4 contains no specific requirements for lighting.

Comm 63.0701 Use of ASHRAE 90.1
Delete the current requirement since the reference to use the ASHRAE 90.1 standard is referenced under IECC chapter 8.

Comm 63.0802 (1) Greenhouses
The modification will be retained since there is no similar requirement under IECC 801.2

Homework assignment

As homework, members are to continue to review and evaluate the current Wisconsin Energy Code modifications to see whether they could be eliminated or need to be revised in light of the 2003 and 2004 IECC changes.

Next meeting

The next meeting has been scheduled for Tuesday, February 8, 2005 in conference room #3B in the Thompson Commerce Center, 201 W. Washington Ave., in Madison.

Welcome and introductions
Jim Quast opened the meeting by welcoming the members and thanking them for volunteering their time and expertise to participate on the division’s Energy Conservation Code Council. He noted that the last time this group met the task was to review the energy requirements under the 2000 edition of the International Energy Conservation Code (IECC) for adoption in Wisconsin. That endeavor was much more encompassing at that time since using a model building code was a new concept. Now the goal of this group is to review the changes made in the 2003 IECC as well as the 2004 Supplement in anticipation of adopting the 2006 edition of the IECC, and to also review the existing Wisconsin-based requirements for need. The projected effective date of the WCBC, which would adopt the 2006 IECC would be July 2007.

The Division’s Advisory Council Manual was distributed and explained to the members. It was also noted that the final work of this Council would be forwarded to the umbrella councils for their review. The umbrella council review of this group’s initial recommendations will begin early next year.

Discussion of Projected Work and Summary Sheets
Jim Quast explained the energy handout material and pointed out that the summaries are staff’s analysis of the changes and encouraged the members to review the actual code language. The major change to the energy rules under the 2004 ICC Supplement was the elimination of IECC chapters 5 and 6 relating to residential buildings and the consolidation and simplification of the energy requirements for low-rise residential buildings. It was Jim’s understanding that the residential changes under the 2003 IECC or the 2004 ICC Supplement would not be considered major or significant from the current energy requirements.

Jim explained that the most significant impact in light of the IECC changes may be to subchapter III of Comm 63. This subchapter provided alternate energy standards for commercial buildings based upon the 1999 edition of ASHRAE 90.1 standard. The 2003 IECC now references and reflects the 2001 edition of the ASHRAE standard. It is also Jim’s understanding that the 2004 ASHRAE standard will be proposed to be incorporated into the 2006 IECC. Therefore, one matter for the council to consider would be the possible elimination of Comm 63 subchapter III. The ASHRAE standards will not be provided for each member; however, if the members feel there certain sections within the ASHRAE standards that need to be reviewed or discussed, staff will make copies of these sections for their review.

Jim also indicated there a few other groups working on energy issues and the work of these committees might affect the work of this Council. The We Energies Code Collaborative and the Governor’s Energy Conservation Task Force are recommending modifications relating to lighting and building envelope requirements. The members discussed whether a separate subcommittee or task group could be formed with experts to research and propose requirements for lighting, and Jim expressed that it could be a possibility.

Identification of future discussion items
The following issues for further discussion were identified at the meeting:
Lighting controls
Building envelope requirements
Insulation, vapor barriers and condensation occurring at below-grade walls
Coordination of energy rules with other model codes, such as the National Electrical Code for lighting levels
Exterior lighting levels
Ensuring that any modifications or additions to the IECC are enforceable
Daylighting concepts

Jim Quast encouraged the members to review the 2003 and 2004 IECC changes with their organization so any issues or concerns raised by their members could also be discussed at the next meeting.

Chairperson
The selection of the chairperson was postponed until the next meeting. Members expressed a preference of having Bob Wiedenhoefer serve as the chair.

Homework assignment:
As homework, members are to review and evaluate the current Wisconsin Energy Code modifications to see whether they could be eliminated or need to be revised in light of the 2003 and 2004 IECC changes.

Next meeting
The next meeting has been scheduled for Tuesday, December 7, 2004 in conference room #3B in the Thompson Commerce Center, 201 W. Washington Ave., Madison.
