For Feature 04 VOC Reduction, which documentation is required?

• A. LOA from MEC engineer
• B. Commissioning Report
• C. Occupant survey
• D. LOA from architect and contractor

Answer: (C)

VOC Reduction aims to limit occupants’ exposure to volatile organic compounds and to ensure odors and IAQ concerns are minimized in real-world conditions. The most direct way to verify that these improvements are actually felt by people in the space is to gather occupant feedback. An occupant survey captures perceptions of air quality, odors, and any related symptoms, providing evidence that VOC-related issues have been addressed and the intended health and comfort benefits are achieved. This occupant-centric documentation aligns with the goal of VOC Reduction by showing how the space performs for its users, not just in theory or under controlled tests.

Other documents like a commissioning report or letters of assurance from various professionals may be valuable for different aspects of building performance, but they don’t directly demonstrate occupant-perceived improvements in VOC-related IAQ in the field, which is why the occupant survey is the required documentation for this feature.
