CourseDescription
indoor air pollution on human health. They will also be able to identify sources of indoor air pollutants and view several case studies of the effects of controlling versus not controlling indoor environmental quality at the design phase of building construction. Emphasis is drawn to the importance of emissions of VOCs over content only requirements. Moreover, the participants will learn the value of selectingparticipants will learn the value of selecting certified low emitting products as a proven method for controlling VOC emissions (volatile organic compounds) that invade the indoor environment.
LearningObjectives
At the end of the this course, participants will be able to:
1. Understand the impact of indoor air pollution on human health
2. Identify sources of indoor air pollutants
3. Understand the difference between low VOC emission and low VOC content
4. Understand the value of selecting gcertified low emitting products

26 un‐tinted paint samples tested Stated content VOC level between 0 g/l and 150 g/lTested using dynamic Environmental Testing chambers and 14 day testing
Content v. Emissions
.
Findings:7 samples had formaldehyde emissions above the CA CREL limit for dry product emissions (9ug/m3)2 samples had ethylene glycol emissions above the ½ CA CREL limit (200ug/m3)
Conclusions:VOC content can not be correlated to VOC emissionsImpact: If used, TVOC levels may impact building clearance testing

Learning Assessment1. What is a VOC? What is TVOC?
2. Name 3 types of pollutants in the indoor air we inhale every day
3 How do these pollutants affect our health?3. How do these pollutants affect our health?
4. How do these pollutants affect the building?
5. When in the building life cycle must Indoor Air Quality be considered: design, construction, or operations & maintenance?
6. Why Is California DPH Section 01350 inadequate in assessing emissions?7. List 3 resources to evaluate the “greenness of a product”8. A product that is low content VOCs is always low emitting of VOCs. T or
