v2 - LEED 2.2

Inquiry

This Credit Interpretation request is in reference to the EQ Credit 3.2 (Construction IAQ Management Plan - Before Occupancy). In lieu of the two-week building flushout, our team has chosen to perform baseline IAQ testing. Per the Credit Interpretation Ruling on 10/8/2002, we will utilize an alternative on-site IAQ testing procedure to the method described in the LEED Reference Guide. Although the credit interpretation is clear to the methodology allowed, our team still has a question regarding specifics of the allowed testing procedure. One sample each for airborne particulate levels, formaldehyde, 4-PCH, and total volatile organic compounds (TVOC) will be collected on each occupied floor of the building. Because there is no approved analytical technique for "total organic compounds, the TVOC sample will be collected and analyzed in accordance with the US EPA\'s TO-17 procedure. These samples will all be collected prior to building occupancy. Please let us know if this method of sample collection and testing is acceptable.
