Airflow in solar passive buildings affects indoor air quality and thermal comfort. A study on a university library used software to simulate conditions for summer and winter days. Solar energy was used to improve comfort and reduce energy use. The study compared passive and active ventilation systems. An optimal air change rate of 2-3 renewals per hour was found for winter and summer conditions, balancing comfort and air quality.
