Exploring the Indoor Air Quality in the context of changing climate in a naturally ventilated residential Building using CONTAM

Indoor Air Quality (IAQ) of residential buildings is a crucial field of study as it aims important subjects: providing healthy indoor air to inhabitants, avoiding high pollutants concentration and impacts of extreme heat events along with climate change and global warming concerns. In order to set up a performance-based method, a critical question has to be answered: What are the relevant IAQ performance parameters that are mostly affected in the context of climate change? To address this, a measurement campaign was carried out in summer of 2021 at south of Belgium. Indoor temperature, relative humidity, CO, Particulate Matters (PM2.5, PM10), Volatile Organic Compounds (VOCs), NO, NO2 and O3 concentrations were measured with fabricated monitoring devices of low-cost sensors, as well as the corresponding outdoor values. In the first step of this study, IAQ parameters are computed using designed model with CONTAM software for the test house. In the next step, the validation of the developed model is investigated.
