North Carolina Reverses Building Code Changes

first_imgA lost opportunity for consumersWhy take all the time to consider and approve new building codes only to undo most of the work six months later? That was the question from Bridget Herring, a new appointee to the council and the only person to vote against the latest revisions.“I do not have any questions other than why we would amend the code we just adopted,” she told the Code Council before the vote.Councilors, however, said it wasn’t unusual to approve a policy with the idea it would be changed later.“Rather than hold up the whole energy code, we would let something go through, knowing that we were going to revisit it again,” Robbie Davis, the newly elected chairman of the 17-member panel, told Southeast Energy News.Bill Fay, director of the Energy Efficient Codes Coalition, called the reversal a “slap in [the] face of North Carolina home buyers” and told the Codes Council its decision means that North Carolina is falling behind despite the fact it’s one of the fastest-growing states in the country.“Why should we let the builders write the code?” Fay asked.According to the International Code Council, as of July 2017 North Carolina was one of 15 states using the 2009 version of the energy code. Eight states, including North Carolina, have adopted the 2009 International Residential Code. Other states have moved to new versions of the codes published in 2012 and 2015. A number of states have adopted parts of the codes but don’t apply them to all buildings. Are We Really Better Off With Building Codes?Are Energy Codes Working?An Overview of the 2012 Energy CodeICC Approves Changes to Energy Code A question of costDavid Smith, a builder from Wilmington, North Carolina, and the chairman of the council’s residential committee, said in a telephone call that the changes sought by the builders association affected only a small portion of the new code and that many of the committee’s earlier changes were left intact.“Cost is always a factor,” he said of more stringent energy requirements for new construction. “The more you increase the cost, the more it affects affordable housing — which is already almost an oxymoron; the cost of housing is out of sight. We try to make sure we keep the cost of housing down as much as possible so more and more families can get into homes. It’s a lot more than ‘I’m against’ or ‘I’m for’ something.”Smith said that advocates for tougher building requirements played an “extremely important part” in making code revisions, and that he understood their frustration over the council’s most recent vote.“That upset the proponents of the energy code, and I can understand it because that’s what they do, and thank goodness we have them there. We just can’t do it all. I can build a house right now that wouldn’t cost you hardly anything to heat or cool and could stand up to a hurricane or a tornado, but at what cost do you want to build that home?”If cost was a chief reason for softening the energy requirements, the council got no specifics in its December deliberations. Code Council Chairman Robbie Davis, a Rocky Mount, North Carolina, builder, said the homebuilders association didn’t say exactly how much it thought the energy upgrades would add to the cost of a new house.Privott was not available to talk about the changes. Last June, the North Carolina agency responsible for making changes in state building codes voted in tougher energy efficiency standards for new residential construction. By December, on the urging of the North Carolina Homebuilders Association, the Building Code Council had reversed course, voting 15-1 to junk some of the changes because they would be too costly.Using the 2015 version of the International Energy Conservation Code as a starting point, an ad hoc committee deliberated for months on how to tweak the state’s residential building code. The Code Council voted in June to accept the committee’s compromise requiring more insulation and less air leakage in new houses, according to a report posted by Southeast Energy News. The recommended changes were expected to become part of the 2018 North Carolina residential code taking effect in 2019.Jeff Tiller, a sustainable technology professor at Appalachian State University who helped write the new code as a member of the committee, described the changes as “relatively minor,” and “reasonable.”But Robert Privott, a lobbyist for the North Carolina Homebuilders Association and also a member of the same committee, proposed in December that the Code Council roll back some of the new requirements, in effect retaining pieces of the 2009 IECC in the next version of the state’s residential code. RELATED ARTICLES The proposal from the homebuilders association eased requirements for U-factors in skylights and lowered code minimum R-values for insulation in ceilings and walls. For example, code changes previously approved by the Code Council would have required wood-framed walls to have R-15 of cavity insulation or R-13 of cavity insulation plus R-2 of continuous insulation in Climate Zone 3. The builders association instead suggested the insulation requirement remain at R-13, according to the agenda for December’s council meeting. The maximum permissible U-factor for skylights in Climate Zone 3 rose from 0.55 to 0.66. The next round of changes is a long way offHerring, the energy program coordinator for the city of Asheville, told GBA that the energy code changes that had been approved in June were a compromise between the 2009 IECC on which current North Carolina code is based and the 2015 version of the energy code.She said the payback from changes approved in June would have justified the investment, and that she considered the rollbacks approved in December a significant change.“North Carolina has moved from a three-year code cycle to a six-year code cycle, so we are only planning on an update every six years,” she said by telephone. “We are going to fall further behind, and there are going to be larger changes if we don’t take some small steps forward. I would rather take small incremental steps that are cost-effective, and I do believe that was a cost-effective requirement.”A pending rate increase from Duke Energy is another factor, she said. “Those slight advances in efficiency would have helped offset the cost of our increased utility rates that are potential coming down the line.”Further tinkering is still possible. The rewritten codes will become the state’s 2018 building codes and go into effect on January 1, 2019. Decisions the council makes now are still subject to review by the North Carolina Legislature, and council rules allow code changes to be proposed at any time.last_img
