Review current relevant amendments for possible changes
Staff mentioned the amendment to allow R-6 insulation on ductwork instead of R-8 when 50 percent of the duct system is covered in insulation has been removed and will revert to the code provision of all R-8 insulation in the attic.
Mohr moved to strike sections 5-313.5 and 5-604.5 concerning dryer vent provisions and revert to original provisions in the code. Seconded by Chaney. Pass 4-0.
The board discussed condensate drain pipe sizing provisions and agreed to accept the minimum sizing chart provided by Mohr. The board also requested staff to draft an amendment that included provisions to connect a maximum of three condensate drain lines unless a minimum 1.5” common drain is used and included a cleanout for maintenance.
Blanchard inquired about the maximum flex duct length and would rather see a maximum of 6’.
Chaney replied he first tried in the past to get the maximum length to 5’ and the board finally settled on 15’ maximum.
Mohr made a motion to limit flexible duct in commercial buildings to 8’. Seconded by Blanchard. Pass 4-0.
Discuss changing quorum of board.
Staff advised the state statute had changed that allowed the quorum of a five member board to be three but then two members could not discuss board business without violating open meetings act. The statute now allows two people to discuss board business without violating the open meetings act. The board decided to leave the amendment as it is and stay with the quorum of four members.
Elect Chair and Vice-Chair
Chaney nominated Gary Mohr as chair. Seconded by Blanchard. Pass 3-0.
Mohr nominated Kevin Chaney as chair. Seconded by Jarboe. Pass 3-0.
Miscellaneous
Staff advised the board that Bryan Wyatt’s board term was expiring at the end of March and suggested adding up to two additional meetings to complete the review process of the 2009 Codes in order to avoid starting over with the review process with a new board member. The board agreed and added a meeting for February 11th and the regular meeting on February 25th.
Chaney suggested that David Sparkes would be a good board member to fill the vacancy on the board.
Adrian Jones addressed the board regarding before agenda items were discussed. He stated he is the staff liaison for the Building Code Board of Appeals and the building board has been reviewing the 2009 IRC. The building board has recently been discussing energy provisions in the IRC that directly affect the installation of mechanical systems. He has advised the building board that before any proposed amendments are made to mechanical installation provisions, the input of the Mechanical Board should also be taken into consideration. The energy provision that has been added to the code is the requirement that any duct system that is outside the thermal envelope be tested for pressure loss to ensure the duct system is properly sealed and meets the existing provisions of the energy code. He continued the Building Board has had numerous proposals including only testing every seventh system or eliminating the provision altogether. Equity issues arise when only testing every seventh system. Jones also stated he has verified with International Code Council (ICC) when “systems” are mentioned, it is the entire system, including return, supply and building cavities. Other questions that have arisen are who tests the system, the contractor or a duct testing company.
Chaney asked if testing a residential system is necessary.
Mohr responded from an energy standpoint, it makes sense to test the duct systems. He suggested the Mechanical Board take time to discuss the issue and determine what criteria need to be followed.
Motion to adjourn made by Mohr. Seconded by Chaney, pass 4-0. Meeting adjourned at 5:26 p.m.
