Indoor Air Quality is recognised as a
significant environment and health problem
in most countries. |
|
|
The National
Health and Medical Research Council
(1992) defined Indoor Air as: ‘Air within a building occupied for
a period of at least one hour by people of varying
states of health’
|
|
|
The Syndrome being characterized by regular
employee complaints of rashes, colds, fatigue, coughing, dizziness
and breathing problems |
|
|
The Environment
Protection Agency (EPA) criteria for a sick building is met when
20% of the inhabitants complain of related ailments. |
|
|
This is becoming the employment
concern |
| |
 |
|
|
|
Significant decrease in worker efficiency;
concentration and productivity (EPA) |
|
|
United States estimates of annual economic
loss due to poor Indoor Air Quality amounts to several tens of billions
dollars (EPA 1994) |
|
|
Some oversea studies have shown, for
Australia, a 3% productivity loss incurred an annual loss of 3 billion
dollars |
|
|
Causes of the Syndrome are multiple and
varied, but typically associated with inadequate fresh air ventilation,
improper temperature and humidity settings, the presence of volatile
organic compounds, and a contaminated and poorly filtered ventilation
duct system |
|
|
An ongoing proactive approach to the
problem will maintain the building’s environment to Government and
indoor air quality Standards |
|
|
Contaminated indoor air is a
time bomb waiting to explode |
|
|
Indoor Air Quality is the next
growth area for the Heating Ventilation Air Conditioning industry |
