1. Chapter 6: Indoor Air Quality (IAQ) IAQ had recently been brought back to prominence as a result of 1.People spend more time indoors in controlled environments 2.The oil crisis of 1973 produced a rush toward energy conserving design resulting in designs that limited the introduction of outdoor air. 3.A proliferation of chemicals has produced a vast array of pollutants. → Sick Building Syndrome IAQ may be just as important as air temperature when it comes to comfort.

2. Chapter 6: Indoor Air Quality (IAQ) IAQ depends on 4 major considerations: 1.Limit pollution at the source 2.Isolate unavoidable sources of pollution 3.Provide for adequate supply and filtering of fresh air 4.Maintain the building and its equipment in clean condition Table 6.1 Common Air Pollutants Table 4.22 Recommended rates of ventilation
