Ashrae 62.1 IAQ Ventilation Audit Form
This comprehensive log verifies compliance with ASHRAE Standard 62.1, covering minimum outdoor airflow, filtration pressure drop, zone-level distribution, and overall indoor air quality parameters critical for occupant health and system efficiency.
This audit form is designed to verify compliance with ASHRAE Standard 62.1, ensuring adequate indoor air quality (IAQ) and ventilation system performance. It covers critical parameters such as minimum outdoor airflow rates, filtration efficiency, pressure differentials, and zone-level air distribution. Regular completion of this log helps facilities maintain occupant health, optimize energy consumption, and extend the lifespan of HVAC assets.
- Lockout/Tagout (LOTO) must be performed on all VAV box fan-powered units and air handling units prior to opening access doors or changing filters.
- Required PPE: safety glasses, cut-resistant gloves, N95 or better respirator, and voltage-rated gloves (when working near live electrical components).
- Calibrate all measurement instruments (anemometer, manometer, tachometer) within 30 days prior to audit.
