Every year, about 3.8 million people die globally from illnesses attributed to indoor air pollution. The pollution is usually caused by inefficient use of kerosene when cooking. For developed nations like the US, on the other hand, the most dangerous causes of poor indoor air quality are tobacco smoke and radon. Radon is especially dangerous because it is odorless and colorless. As a result, it cannot be detected without a special testing device.

2. Every year, about 3.8 million people die globally from illnesses attributed to indoor air pollution. The
pollution is usually caused by inefficient use of kerosene when cooking. For developed nations like
the US, on the other hand, the most dangerous causes of poor indoor air quality are tobacco smoke
and radon. Radon is especially dangerous because it is odorless and colorless. As a result, it cannot
be detected without a special testing device.
The quality of indoor air in residential and commercial buildings also decreases because of the
presence of mold and other harmful chemicals like carbon monoxide and formaldehyde.
A few of the detrimental health effects which poor air quality causes are eye and nose irritation,
headaches, dizziness, and fatigue. Additionally, recent studies have been linking the quality of
indoor and air to the cognitive function and overall mood of workers.
Indoor Air Quality and Productivity
A joint study by Harvard University and Syracuse University has associated indoor air quality and
productivity levels of employees. It was found that inadequate ventilation, high levels of carbon
dioxide, and indoor pollutants adversely affect the focus of workers.

3. The participating employees in the study were tested under two different settings: one with regular
office conditions and one with improved ventilation (green conditions). Employees working in the
space with green conditions performed 61 percent better on cognitive tasks than in the typical office
state.
Employee productivity levels can be increased with improved outdoor airflow rate, more efficient
ventilation, and decreased emissions.
Guidelines for Improving Indoor Air Quality in Commercial Spaces
The Environmental Protection Agency has recommendations on improving the air quality of buildings.
These include compliance with building smoking policy, maintenance of office plants, and prompt
and proper disposal of garbage. Another approach is opening office windows and vents to allow entry
of outdoor air.
With better air quality comes better employee performance. Meaning, when business owners invest
in their office ventilation, they also invest in their output.
