PHOTO REQUIRED of Mechanical Ventilation Test Results, equipment nameplate/model number and controls per MINHERS Chapter 9. Raters/RFIs are responsible for documenting reasons for missing photos. Ventilation is tested according to ANSI/RESNET/ICC 380. The rater should include sufficient documentation to support the ventilation type, flow rate, wattage and frequency modeled.
- Ventilation wattage can be verified via published OEM data, third party database (i.e. HVI.org) or on-site measurement via Watt meter.
- Air flow measurement methods are described in ANSI/RESNET/ICC 380 and rater should include sufficient documentation to support the modeled airflow rate.
- Usage of Operable Windows (Natural Ventilation): Confirm that the type of ventilation that occurs or is most likely to occur matches the Cooling Season Strategy modeled: 'No Ventilation', 'Natural Ventilation', or 'Whole House Fan'.
SCORING:
"Satisfactory" when correct or "Unsatisfactory" when incorrect or NO PHOTO.
GUIDANCE:
Ventilation Type - Value in software corresponds with supporting docs or onsite verification Flow Measured? - Rater/RFI correctly noted in their supporting docs whether or not they performed the testing or through onsite verification Measured Flow Rate - Field QA: QAD tested value within 10% of Rater/RFI value. File QA: Value in software matches supporting docs or onsite verification OR at least one photo provided from Rater/RFI which shows test results Fan Watts - Value in software corresponds with supporting docs or onsite verification Operational hours per day - Value in software corresponds with supporting docs or onsite verification
