For a company, your greatest asset is your employees. That’s why indoor air quality should be a priority for each and every company. The quality of the air in your building can have a huge impact on the health of your workers and in turn affect the productivity of the building.

Controlling indoor air quality is not a quick and easy fix; there are many factors that impact the quality of the air. The major factors include:

Part 1 of a 3 part series will focus on the buildings heating, ventilation, and air conditioning (HVAC) system.

The Buildings HVAC System: Improving Indoor Air Quality

Controlling your buildings indoor air quality requires a large focus on the buildings heating, ventilation and air conditioning (HVAC) system. Everything from the ductwork to the air filters play a role in removing pollutants in the air. The HVAC system can act on both sides: it can help remove contaminates from the air and it also can be a primary distributor of pollutants if not properly maintained.

These are the components that you should focus on for indoor air quality management:

System Design

When one area of a building serves a different purpose than another, it may require a different amount of attention. You wouldn’t treat a room occupied by workers the same as an area used for storage. Each require modification to deliver proper air for the space.

Air Supply

Fresh air is a necessity in working environments. To ensure that pollutants from equipment, materials, furnishings, and people are diluted, outside air needs to be brought in and distributed throughout the facility.


Yes, fresh air is a necessity, but what happens when the air outside is polluted with pollen, carbon monoxide or dust. That’s where filtration comes in. The right filters that are properly maintained and installed can trap particles before they become a problem. Chemical contaminants and gas may need specialized filtration.


Finding a small issue before it becomes a huge problem is the benefit you get from preventive maintenances. The quality of air in the facility depends on maintenance programs.

Furniture and Equipment Placement

Indoor air quality can also be affected by something as simple as a desk or shelf placed in the wrong spot. Where equipment is located in the facility matters, and that’s something that should be kept in mind. Placing a machine that gives off heat near a thermostat may affect the ventilation. Shelves being placed in front of a vent can affect the air quality as well.
