The objective of this study is to analyze the PM<sub>2.5</sub> reduction and its health benefits according to introduction of energy recovery ventilator (ERV). For this purpose, an IAQ model, a concentration-response function-based health impact assessment model, and an energy model reflecting the architectural characteristics of small-sized multi-use facilities were used to estimate annual medical expenses and energy costs. The unspecified occupants of multi-use facilities were quantified by age group based on domestic time-activity statistical data. In addition, to reduce the uncertainty in health-benefit analysis and compare the economic feasibility of different scenarios under various operating conditions, changes in cost-benefit ratios were analyzed according to mortality valuation costs and minimum ventilation rate variations. The results showed that introducing ERV with 50% and 90% filter efficiency led to health-benefits per hour of visit ranging from 282-907 KRW/h/person and 365-1178 KRW/h/person, respectively, depending on age group, and this was found to be 1.86 to 2.42 times higher than natural ventilation. Even when premature mortality prevention costs were excluded for conservative estimation of health-benefits, the cost-benefit ratios for the HRV adoption scenarios remained at 15.1 and 19.0, confirming their economic feasibility. Additionally, the use of an ERV with 90% filter efficiency showed the highest cost-benefit ratio under high airflow conditions (26-36 m³/h/person), suggesting that it is a highly viable economic alternative for small-scale multi-use facilities in terms of both health and energy efficiency.
