146462 - Investigation of the Stack Effect on the Impact of the Outdoor Air Quality on the Indoor Environment 

This study investigates the relationship between outdoor air quality and its impact on indoor environments, employing the CONTAM modeling tool for comprehensive analysis. Our findings reveal a significant correlation between outdoor temperature, relative humidity, and the occurrence of infiltration or exfiltration, thus shaping indoor air quality dynamics. The current results reveal that indoor conditions are heavily influenced by external atmospheric factors. Specifically, stack effect (variations in temperature) and humidity determines the direction of airflow, either allowing pollutants to infiltrate indoors or facilitating their expulsion. This study proposes effective management of fresh air intake and indoor static pressure in mitigating adverse indoor environmental conditions. The implications of this research extend to diverse domains, ranging from building design and ventilation systems to public health, offering actionable strategies for fostering healthier indoor environments.
