Common Issues: There is often confusion regarding the difference between New Construction and Schools requirements for IEQc4: Low Emitting Materials. The referenced standard for the Schools rating system is different from the BD+C requirements. In the LEED for Schools Rating System, all adhesives and sealants installed in the building interior (defined as inside the weatherproofing system and applied on-site) must meet the testing and product requirements of the California Department of Health Services Standard Practice for the Testing of Volatile Organic Emissions from Various Sources Using Small-Scale Environmental Chambers, including 2004 Addenda.
An approved Alternative Compliance Pathway is available and commonly attempted, which allows Schools projects to pursue the BD+C compliance pathway for IEQc4.1-4.4. However, frequently teams do not provide the documentation required by those BD+C credits.
Suggestions: If the team wishes to pursue the approved Alternative Compliance Pathway, the team should indicate this by checking the Alternative Compliance Pathway option in the credit form, and indicating that the IEQc4 PIEACP is being attempted. In this case, all required information and documentation for the chosen BD+C credit must be provided including the applicable LEED NC v2009 credit forms. The ACP does not apply to EQc4.5 or 4.6, which are exclusive to the Schools rating systems.
