Indoor Air Quality (IAQ) Analysis

In Australia, the National Construction Code (NCC) and AS1668.2 are the primary standards for ensuring good indoor air quality and ventilation in buildings. These standards provide guidelines for minimum ventilation rates, air filtration, and control of indoor pollutants to ensure the health and comfort of occupants. There are several applications for these standards, including car parks, hospitals, commercial kitchens, and more.

In car parks, ventilation systems are crucial to ensure safe and comfortable conditions for drivers and pedestrians. The NCC and AS1668.2 specify minimum ventilation rates to remove pollutants such as carbon monoxide (CO) and ensure a comfortable environment for users.

In hospitals, air quality is of utmost importance to protect patients, staff, and visitors. The NCC and AS1668.2 guidelines for ventilation rates and air filtration are essential in preventing the spread of airborne infections and ensuring healthy indoor air quality. CFD analysis can be used to assess the ventilation systems in hospitals and optimize them for maximum efficiency.

In commercial kitchens, the buildup of grease is a significant concern that can impact the effectiveness of ventilation systems and increase the risk of fire. The NCC and AS1668.2 specify guidelines for ventilation system design and maintenance to prevent the accumulation of grease and maintain good air quality in these environments.

CFD analysis is an effective tool for evaluating and optimizing ventilation systems to ensure compliance with the NCC and AS1668.2 guidelines. It can help identify areas of stagnant air or poor ventilation, assess the effectiveness of ventilation systems in controlling indoor pollutants, and provide recommendations for improving airflow patterns and minimizing the risk of airborne illness transmission.
