Basement Ventilation Analysis is a critical simulation study conducted as part of Environment Clearance (EC) submissions to evaluate air quality, pollutant dispersion, and ventilation efficiency in enclosed parking and service basements. The assessment focuses on ensuring compliance with EC Committee safety and environmental expectations by analysing carbon monoxide (CO) concentration levels, air change effectiveness, fresh air supply adequacy, and exhaust performance under various operational conditions.

Using advanced airflow modelling and pollutant dispersion simulations, the study verifies whether the proposed mechanical ventilation system can maintain safe indoor air quality levels, prevent pollutant accumulation, and ensure occupant safety. The analysis also supports optimization of fan capacity, duct layout, jet fan positioning, and emergency smoke extraction systems, strengthening both regulatory approval and operational reliability.
