New Effort Will Streamline Green Building Standards

Five standard developers in the U.S. join forces to create a 'single, holistic' green building system, but adoption is years away

Posted on Aug 27 2014 by Scott Gibson

Five of the country's most influential developers of construction industry standards have announced a joint effort to create a single green standard that would be more coherent and cohesive than the jumble of overlapping green building standards and regulations that currently exist.

The agreement is an attempt to create a "single, holistic system" integrating the U.S. Green Building Council's LEEDLeadership in Energy and Environmental Design. LEED for Homes is the residential green building program from the United States Green Building Council (USGBC). While this program is primarily designed for and applicable to new home projects, major gut rehabs can qualify. program, ASHRAEAmerican Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). International organization dedicated to the advancement of heating, ventilation, air conditioning, and refrigeration through research, standards writing, publishing, and continuing education. Membership is open to anyone in the HVAC&R field; the organization has about 50,000 members. 's 189.1 building standard, and the International Green Construction Code (IgCC), according to an article posted at Environmental Building News(EBN).

For those designing or building single-family homes, however, changes are probably years away. The new agreement is not expected to be in place before 2017 at the earliest, and it will not initially have any jurisdiction over what regulators call "the low-rise residential sector."

The new system will have three parts

The five organizations involved in the effort are ASHRAE (what used to be the American Society of Heating, Refrigeration and Air-Conditioning Engineers), the American Institute of Architects (AIA), the Illuminating Engineering Society (IES), the International Code Council (ICC), and the U.S. Green Building Council (USGBCUnited States Green Building Council (USGBC). Organization devoted to promoting and certifying green buildings. USGBC created the LEED rating systems.).

According to the EBN report, the cooperative effort will result in a three-part system:

  • An updated version of the 189.1 standard.
  • IgCC, which becomes an "adoptable, code-enforceable version of 189.1" but ceases to be developed as an independent system.
  • The LEED (Leadership in Environmental and Energy Design) rating system.

The individual components will work together in a more coordinated way than they do now.

Speaking to EBN, ASHRAE President Tom Phoenix said, "Had we continued down the separate paths, there is always the chance that someone eventually is going to lose in that game. I think this is a win-win for everybody."

A mixed bag of standards led to some confusion

If you're not a code specialist, all of this may seem like a big bowl of alphabet soup. Brendan Owens, LEED vice president for technical development, posted an article in which he explains the background and how the new cooperative effort will be an improvement.

In 2005, he writes, the USGBC, ASHRAE, and IES collaborated on the ASHRAE 189.1 standard. In a parallel effort, the ICC started developing the International Green Construction Code.

"All of these tools started to appear in the market and jurisdictions appeared to be very confused," he said by telephone. "We had this situation where there wasn't an articulate and planned framework in the market and each organization was just talking about this and trying to clarify it on their own, and we weren't having the effect we wanted to have."

The fact that the five organizations are working together is, Owens said, one of the most important parts of the agreement.

Changes in residential approach could come later

The agreement covers commercial and high-rise residential construction, but not single-family homes. That's partly because neither the 189.1 standard nor the scope of the technical content in the IgCC covers single-family (low-rise) construction, Owens said. In time, however, the same approach could be applied to low-rise residential.

"If I were a residential builder," Owens said, "I would see that this is a model that could potentially streamline and harmonize a lot of local programs that are out there and their relationship to code. When the USGBC and ASHRAE, ICC, AIA, and IES are successful in developing an organized framework of how codes, standards, and rating systems all interact, I think the model is replicable on a residential scale."

Should that happen, Owens said, residential builders should find the regulatory landscape much easier to navigate.

I hope, soon enough, the residential codes push the envelope (no pun intended) to higher levels of better building, healthy and high-performing homes, where we would not have any need for these alphabet soup of green programs.
For the last 15 or so years, our industry has been in constant argument and BS (not bldg science) about which green program is better, which is more stringent, or which is more affordable. Most of these programs have morph to a money racking programs, where fees for this and fees for that are the real reason. Let's call the spade a spade!
