IGCC Provides Alternative Green Building Code Option
Back in October 2010, Doug Reiser and I co-presented on the topic of substituting LEED for traditional building codes. As we were finishing our presentation, I reiterated our primary theme that LEED standards should not be used as a building code. One of the audience members raised her hand and asked why weren’t we discussing the International Green Construction Code (IGCC).
That audience member was right--states are beginning to consider the adoption of IGCC as a state-wide green buiding code in lieu of LEED certification requirements.
The IGCC is available for a free download. I suggest you take a look at it. At the front of the code is a “Roadmap to the International Green Constructon Code” that I found to be helpful:
“Chapter 3 is the core of the (IGCC). It is formatted to: facilitate the customization of this code to address local issues; provide options for construction which exceed the minimum requirements of this code; and provide for the implementation of best practice. . . .
All of the provisions of this code, other than those selected by the jurisdiction in Table 302.1 and those designated as project electives, are mandatory as applicable.”
Rhode Island was one of the first states to adopt the IGCC. Interestingly, Rhode Island adopted the code as an “‘equivalent standard’ to meet requirements that all new major facility projects by state agencies be constructed as green buildings.”
Do you see other states adopting IGCC as an “equivalent standard” to other green building rating systems?
Chris:
My understanding is that LEED is a rating system or program, not a standard. Legally, there are very different meanings between those terms.
For example, ICC-700 is a standard. From that standard, NAHB bases their NAHB Green rating system.
IGCC is a code document currently in development and scheduled for completion this year, with adoption beginning in 2012. This document would give jurisdictions the ability to require a to-be-determined level of sustainability to their new and remodeled buildings.
Remember that some states, like Colorado, do not have a statewide code for any of the international or uniform building codes. Rather, individual cities and counties are free to adopt whatever code they prefer, with or without modifications. While I suspect some Colorado cities may adopt the IGCC, it probably will be as their principal standard, rather than an "equivalent" standard.
Hey Chris, I completely agree that LEED should not be used to substitute building codes. After a cursory view, it seems that IGCC may be a viable option.
The bottom line is that LEED is quickly becoming a baseline and we need to move past that. We need the policies and financing to change so we can scale all of these things.
That's where the focus should be. As always, thanks for making me think.
