1. The fundamentals of Indoor air quality Simon Turner LEED AP, WELL AP
Welcome to Healthy Building’s “Introduction to indoor air quality.” This course will be approximately 90 minutes in length designed to educate building professionals on the principles of Indoor Air Quality and developing successful IAQ management programs. It also serves to fulfill the training requirement for The Leadership in Energy and Environmental Design EQ Credit 1.1: Indoor Air Quality Management Program.

3. Some history

4. Human symptoms
Sick Building Syndrome is a term used to describe a general and non-specific complaint that occurs when the occupant is present in the building. In SBS the specific source of the complaint is not routinely identified. It may be a combination of factors.
Building Related Illness is the term used to identify a specific source or activity in the building responsible for the symptoms. This might include Legionella bacteria, mold growth, or an improperly located exhaust vent that impacts the indoor air quality.
Multiple Chemical Sensitivity is still a debatable term to describe certain individuals who appear to maintain one or more severe allergies that may be linked to the building. These individuals have physical responses typically well below the threshold of the typical population.
But what are the factors that give rise to these illnesses in buildings?

5. Causes Poor IAQ Proliferation of chemicals Tighter building envelopes
Reduced ventilation
Deferred maintenance
Inadequate operating budget
Perception and expectation
Poor IAQ
How did it come to be this way? Our steady movement away from an agrarian based society to an information based one, has brought us all indoors. Many believe it is the proliferation of chemicals used in our buildings or the construction of tighter building envelopes to conserve energy. Some believe reduced ventilation is to blame. Maybe deferred maintenance is the issue - with more and more pressure to minimize the operating budget. Mix enough of these issues together and its easy to imagine the effect this has on your perception of a healthful workplace.

6. Factors Affecting IAQ
Well it’s not fully understood, but one of the most common factors affecting IAQ is the indoor climate- this is comprised of temperature, humidity, and airflow. When these factors are not well managed, complaints are quick to ensue.
And to make matters worse, thermal discomfort tends to lower the tolerance to other IAQ factors.

7. The Basics Carbon Dioxide Carbon Monoxide Particulate Matter
Microorganisms
Volatile Organics
Water

8. Contaminants Tobacco products Office equipment Cooking/microwave
Occupants and activities have the capacity to add a number of contaminant sources to a building. Cooking activities and poorly exhausted office equipment. Simple overcrowding can add a burden to the air quality as well.

11. Strategies for Control
Management policies
Pollution transport
Air flow pathways indoors & outdoors
HVAC/Ventilation
When we talk about strategies for controlling air pollutants in buildings, there are 4 main concepts. The first involves written procedures, or management policies that help personnel and contractors comply with protocols that reduce building exposures. The second is understanding the driving forces of pollution transport – how contaminants move from one place to another. The third is understanding the sources themselves be they indoor or outdoor. And finally we cover the important role of ventilation in source control.
