As a member of your local USGBC chapter you recognize the importance and reach of the USGBC’s LEED Rating System. In November the USGBC began a public comment period on an updated version of the LEED Rating ( system.

According to the USGBC, it is expected that this comment period will lead to substantial changes and improvements to the proposed draft credit revisions. As someone who works with LEED on an ongoing basis you want it to not only represent the best in sustainable building, but also be understandable and easily implemented.

Unfortunately there are some problems with the draft credit language for IEQ Credit 4.0 and if not fixed they could have a negative effect on the indoor environment in these high-performance green buildings. These issues include:
• The proposed low-emissions credit fails to make product emissions requirements more stringent.
• At a time when pollutant source control is desperately needed to protect human health, the proposed credit introduces a layer of complexity that will likely discourage project teams from pursuing it.
• Differing product emissions requirements within the proposed credit mean that LEED Certified buildings in North America could have worse indoor air quality than those constructed outside of North America.
• Poorly defined and inconsistent product emissions criteria and test methods within the proposed IEQc4 mean that some qualifying products could emit higher levels of chemicals than others, posing a significant exposure risk.
• A lack of direction, appropriate reference methods, and verification requirements in IEQc4 will lead to confusion, misapplication, and abuse of the credit, which will marginalize indoor air quality.

All comments must be submitted to the USGBC by January 14th!

Please help protect the health of LEED building occupants by submitting your comments today. For more information on the proposed language, sample comment language and instructions on how to submit comments to the USGBC, please visit
