Why Healthy IAQ Starts at the Bottom:  Stack Effect

Steven Caulfield, PE, CIH
Turner Building Science & Design, Harrison, ME

About this program:

If you think what happens in the basement stays in the basement you don't understand air flow in houses. In this session, we will explore the phenomenon of stack effect from what the root causes are, what effects it can have on your building, to what steps can be taken to reduce its effects. This exploration will take us from the dark recesses of the area below grade all the way up to the sky above. We will touch briefly on the various contaminants that may be spread by this temperature- and pressure-driven force, but will leave the details to the later sessions.

1. Learn what stack effect is.

2. Learn the causes of stack effect.

4. Identify some of the contaminants that can be spread by stack effect.

5. How to reduce or eliminate stack effect in your house.
