Training Course: Indoor Air Quality Auditor for Green Compliance Certification

Introduction

Indoor Air Quality (IAQ) is a critical component of healthy, sustainable, and high-performing buildings. Poor indoor air quality can affect occupant health, comfort, productivity, and overall building performance. Effective IAQ auditing enables organizations to identify potential pollutants, assess ventilation effectiveness, monitor environmental conditions, and implement practical measures to improve indoor air quality.

This course provides participants with a structured and practical approach to conducting Indoor Air Quality audits across different types of buildings. It covers ventilation measurement, sampling strategies, indoor air pollutants, moisture and mold, and healthcare airflow considerations where applicable.

Participants will learn how to assess ventilation performance, develop appropriate sampling strategies, identify potential sources of indoor pollutants, collect and interpret IAQ measurements, and evaluate temperature and relative humidity conditions.

The course also introduces the principal instruments and equipment used during IAQ assessments, including calibrated particulate matter monitors, NDIR CO₂ monitors, electrochemical CO/NO₂ instruments, formaldehyde/VOC sampling equipment, temperature/RH loggers, airflow hoods, and pressure meters. Through practical exercises, demonstrations, case studies, and audit simulations, participants will develop the skills required to perform effective indoor air quality audits and prepare practical improvement recommendations.
