I was wondering if any of you have heard of others in Europe who have had trouble with meeting the SCAQMD requirements that LEED asks for in IEQ Credit 4.1 and 4.2. In Europe, many companies provide their VOC information in the form of emissions and not in volume. In LEED v4 it appears that if you are outside of the U.S. you can use emission values instead of volume values. However, as we are currently working on projects in v3 we are unsure how to proceed. Has anyone been able to use emission values instead of volume values in their pursuit of this credit? Or has anyone had any success suggesting in a CIR that they would meet a v4 Beta requirement instead of the v3 req? Thanks

Timothy, I've had the same issue but have so far been told that I'm stuck with the current requirements. Volume and emissions are fundamentally different and can't be compared. Last year's Global Alternative Compliance Paths made great headway into many of the international challenges, but the only part of EQc4 it addressed was flooring systems. I'm not sure why they didn't bring the same logic to 4.1 and 4.2. Now that they've put out that ACP, though, it might give you grounds for a CIR. Let us know if you ever hear any better resolution on this.
