6. INTRODUCTION
Click the triangle and
watch the video…
“Sick Building
Syndrome” is a modern
day condition caused by
badly designed
buildings.
The main source of
problems is often the
lack of ventilation. What
kinds of conditions did
the people in the video
have?

7. EXPLANATION
“Ventilation is the intentional introduction of outdoor air into a space.” (Wikipedia)
It is used:
● to control indoor air quality by diluting and displacing indoor pollutants;
● for thermal comfort
● for dehumidification (the removal of moisture from the air).
Ventilation can be either mechanical or natural.
Mechanical ventilation uses fans to drive the flow of outdoor air into a building.
(Wikipedia)

8. EXPLANATION
When a building or
enclosed space is
poorly ventilated, air
cannot flow in and
out of the building.
This can affect the
people in the
building.
Note:
This will fit better in the
platform.

9. SUMMARY
● Ventilation is the intentional movement of air into and out of a
building.
● Ventilation can be either natural or mechanical.
● Mechanical ventilation usually uses fans to push air into and out of a
building.
● Poor ventilation can have several effects on people in the building,
from stress to frequent illness.
