Course Overview:
This course provides a basic knowledge of an emerging area – Indoor Air Quality (IAQ) in buildings. Learners will realize the importance of maintaining proper IAQ.

Characteristics associated with indoor air contaminants (IAC) are demonstrated, such as
• Particulate matters (PM2.5, PM10)
• Radon
• Volatile organic compounds (VOCs)
• Asbestos
• Bio-aerosols, and more

Safe exposure levels, resulting health effects, measurement techniques, mitigate and control measures of these IAC are discussed.

Other important areas related to IAQ such as building ventilation systems, indoor flow characteristics, sick building syndrome, and thermal comfort are also covered in this course.


Introduction to Indoor Air Quality (IAQ)
-Why do we care about Indoor Air Quality (IAQ)? In the first module, basic concepts of IAQ are illustrated. Besides, Ventilation is effective in improving IAQ in general. We shall look into the ventilation concept, methodologies, and measurement techniques.

Radon and Indoor Aerosol
-In this module, two major Indoor Air Contaminants - Radon and Indoor Aerosol are discussed. Their properties, sources, health impacts, mitigation and control measures are explained. Besides, we will look into another effective method to improve IAQ - Use of Air Cleaners. Some industries, such as pharmaceutical and semiconductor manufacturing, require very high cleanliness indoor environments. We will look into how professionals build cleanrooms for these industries.

VOCs, Ozone and Combustion Related Pollutants
-In this module, three other major Indoor Air Contaminants that can easily be found at home and office. - (1) Volatile Organic Compounds (VOCs), (2) Ozone and (3) Combustion related Air Contaminants (i.e., Carbon Monoxide and Nitrogen Dioxide) are introduced.

Bioaerosols and Asbestos
-In the last module of course, we look into the two other major indoor air contaminants - Bioaerosols and Asbestos. Staying in a clean environment does not mean the environment is comfortable. "Thermal Comfort" is also an issue that we need to consider. We also look into "Thermal Comfort" in this module.

This course is very useful and good.It gives us awareness about waste chemicals and how to avoid it.Reflective review on impact of IAQ on humans.

Issues of concern include indoor chemistry, airborne infection, and the impact on performance.

Societal trends have led to greater indoor pollutant exposure intensity.

Responses to climate change, energy conservation and singular strategies have not been effective in alleviating the deterioration of indoor air quality.

Holistic solutions include innovations, smart technologies and user engagement.

Clear and concise course on the subject, very valuable for all those who work in the field of indoor air quality or want to know more. Clear and understandable presentations, very pronounced even though with Chinese accentuations, and the most correct subtitle transcripts of any Coursera course I have seen so far.

Arepaka. is taking this course right now and found the course difficulty to be medium.

The time schedule is not very clear as I got enrolled through my M.Tech civil Engineering college, MJRACET, Pulicherla Chittoor district Andhra Pradesh, India with Email as

Please let me the know the start date as i could see as 29th October, 2018

Thanks & regards

by Gy completed this course, spending 2 hours a week on it and found the course difficulty to be easy.
The course is well design the learner who want to know about the indoor air quality. The source, health effect, control measure and detection methods of different indoor air pollutants is well illustrate in a easy manner that a normal person can easily understand
