NC-v4.1 EQc2:Low-Emitting Materials

Hello,

I am seeking clarification on a specific requirement mentioned in LEED V4.1 EQ Credit: Low Emitting Materials, specifically on page 235. The document mentions that the range of total VOCs after 14 days (336 hours) should be measured as specified in the CDPH Standard Method v1.2 and reported in three TVOC ranges: 0.5 mg/m3 or less, between 0.5 and 5 mg/m3, or 5 mg/m3 or more.

I would appreciate it if someone could provide any insights into the significance of the three specified TVOC ranges would be helpful.

Thank you for your assistance.

Hi Karim,   I believe you are referring to the requirements of the "VOC emissions evaluation".  Please note that the Reference guide is indicating that in addtion to noting that the product is tested according to CDPH SM v1.2-207, the supporting documentation must provide the "range of Total VOC's after 14 days...".  This result is reported as one of the three ranges (not all three).  Hope this helps.
