This course is intended to provide an introduction to the field of indoor air quality. It should be of value to those charged with the oversight of building systems, environmental engineers new to the field of IAQ, ind ustrial hygienists who desire a refresher course on IAQ concepts, and others who wish to gain knowledge related to the terminology, tools, and fundamental principles related to indoor air quality.

1. Introductory Concepts : buildings as integrated systems; important factors that affect indoor air quality and their relationship to building components and operation; concentration (meaning, types, units, conversions); mass flow rate (meaning, units, mechanisms); mass balance (concept and equation development); simplified models; indoor environment metrics used to assess IAQ; example problems.
2. Basic Comfort Parameters : Temperature (dry bulb, wet bulb); moisture capacity; moisture content; relative humidity; psychrometric chart; basic components of HVAC systems; example problems.
3. Ventilation: terminology (fresh, return, supply air, etc.); flow balance; infiltration (meaning, mechanisms); natural ventilation (meaning, mechanisms); mechanical ventilation; measurement of air flows; measurement of fresh air intake using tracer methods; ASHRAE standards; effects on indoor air quality; use of carbon dioxide as a ventilation indicator; example problems
4. Chemical Contaminants
1. Carbon Monoxide: properties; impacts; concentrations; sources and factors; measurement methods; control/avoidance; example problems.
2. Nitrogen Dioxide : properties; impacts; concentrations; sources and factors; measurement methods; control/avoidance; example problems.
3. Ozone : properties; impacts; concentrations; sources and factors; interactions with indoor materials; measurement methods; control/avoidance; example problems.
4. Volatile Organic Compounds: definitions (VC, VOC, SVOC, TVOC, etc); specific VOCs and their impacts; concentrations; sources and factors; interactions with indoor materials; measurement methods;
control/avoidance; example problems.
5. Radon: radioactivity (terminology); properties, impacts; concentrations; sources and factors; measurement methods; control/avoidance; example problems.
6. Particulate Matter: terminology (aerosols, aerodynamic diameter; ultra-fine vs. fine vs. coarse particles); important characteristics; size distributions; concentrations (types, typical values); sources and factors; deposition processes; measurement; control/avoidance; example problems.
7. Bioaerosols: terminology (types, etc.); airborne bacteria (general, specific examples – tuberculosis, legionella, streptococcus); bacterial concentrations; sources and factors associated with airborne bacteria; measurement of bacteria; control/avoidance of bacteria; mold (general, specific examples); mold concentrations; sources and factors associated with mold; measurement of mold; control/avoidance of mold.
8. Closure : additional issues that arise during course; summary.
