• Building and its environment are in focus owing to health impact attributed to indoor air quality. This study was carried out to assess indoor air quality in terms of particulate matter (PM) and carbon dioxide in a residential building, during COVD-19 pandemic lockdown from March 25 to April 23, 2020, Abha, Saudi Arabia. The PM concentration range for kitchen, bedroom, and hall were 40,000–81000 μg/m 3 (PM 0.3 ), 15,000–26000 μg/m 3 (PM 0.5 ), 4000–6000 μg/m 3 (PM 1 ), 1100–1500 μg/m 3 (PM 2.5 ), 160–247 μg/m 3 (PM 5 ), and 60–95 μg/m 3 (PM 10 ). The results of this study suggest that bedroom needs to be ventilated as CO 2 concentration was reaching 700 ppm during sleep hours. PM concentration was exceeding 300 μg/m 3 (unhealthy) for all particle sizes of PM 0.3 , PM 0.5 , PM 1 , and PM 2.5 except for PM 10 which was also above safe limits (0–50 μg/m 3 ). Also, with influential habit (aromatic smoke), these concentrations increased 2–28 times for PM. The hazard quotient value greater than 1 revealed potential health risk to the inhabitants. Hence, future studies are needed for developing indoor air quality guidelines for residential buildings in Saudi Arabia and better planning and management of energy consumption.
