Using computational models, we identify pollutant sources and simulate existing ventilation systems under various conditions to quantify their efficiency. We provide metrics like contaminant concentration and air-change rate per hour, enabling evaluation and comparison of alternative ventilation strategies.

We simulate airflow through duct networks, including all components (valves, dampers, etc.), to calculate pressure losses and validate that selected fans can deliver required flow. We also analyse flow distribution across branches to balance performance and minimise loss.
