Course Highlights

This online engineering PDH course presents the factors affecting Indoor Air Quality (IAQ): sources of indoor air contaminates, HVAC systems design and operation, pollutant pathways and driving forces, and building occupants. Moreover, this course illustrates how "effective communication" between building management and building occupants is very essential in preventing IAQ problems.


The indoor environment in any building is a result of the interaction between the site, climate, building system (original design and later modifications in the structure and mechanical systems), construction techniques, contaminant sources (building materials and furnishings, moisture, processes and activities within the building, and outdoor sources), and building occupants. Indoor air contaminants can originate within the building or be drawn in from outdoors. If contaminant sources are not controlled, Indoor Air Quality (IAQ) problems can arise, even if the HVAC system is properly designed and well-maintained.


EPA recognizes that IAQ problems present serious hazards to building occupants. Therefore, EPA developed this guide to protect building owners and building occupants from poor indoor air quality and to promote a healthy indoor environment in which the surroundings contribute to productivity comfort and a sense of health and well being.


This 2 PDH online course is applicable to civil, environmental and mechanical engineers, facility managers, building owners and all others who are interested in gaining an understanding of building air quality.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Identifying the elements required in the development of an indoor air quality program
  • Understanding how temperature and humidity affect indoor contaminant levels
  • Learning about the techniques to control odors and contaminates
  • Learning about the symptoms attributed to IAQ problems and their effect on human health
  • Establishing a communication system between building management and occupants that can help prevent IAQ problems
