The mission of the committee is to provide a forum for exchanging ideas and information about indoor environmental quality and to participate in the development and analysis of related technological and regulatory issues. Below is the link from their paper…as always comments are always needed.

The main differences for LEED v4 from LEED 2009 are:

• The addition of PM 2.5 and ozone in EPA nonattainment areas

• The target chemicals listed in CDPH Standard Method v1.1, Table 4-1 (based upon OEHHA CRELs)

• Additional test methods for formaldehyde and TVOCs were also added for LEED v4
