This course will give you a different perspective on an important environmental problem - air pollution. Indoor environments are examples or larger environmental systems and learning to analyze indoor air pollutionproblems will develop skills needed to analyze other environmental problems. Indoor air pollutants can cause material damage to equipment and artifacts such as the Sistine Chapel, and contaminant manufacturing processes. Indoor air pollution adversely affects human health since people spend 80-90% of their time indoors and the concentration of many air pollutants is higher indoors than outdoors. In this class, we study many different indoor environments such as homes, offices, and hospitals. We learn about pollutants including radon, environmental tobacco smoke, and volatile organic compounds. We develop a strategy for designing appropriate control technologies.
