The Importance of Indoor Air Quality in Airports

The topic of Indoor Air Quality (IAQ) management in public spaces is acquiring relevant importance. As seen in airports with their busy and unique indoor environments are currently considered to be hotspots for inadequate air quality. Multiple factors contribute to the potential negative impact on an airport’s IAQ. Ambient levels of pollutants (particulate matter, ultrafine particles, and VOCs) are commonly observed to be high around airports due to emissions from aircraft and ground support vehicles. The introduction and penetration of outdoor pollutants in combination with indoor pollutant sources and occupancy number and activities is expected to affect IAQ of airport terminals and facilities.

International airports are also at risk of disease transmission. The pandemic has drawn more attention to the dangers associated with IAQ within airport facilities, and managers and leaders are looking for ways to effectively protect passengers and staff.

By demonstrating care and concern about IAQ is simply another form of safety that every airport should be interested in. As it becomes a growing determination factor on customers’ decision to return to travel.

There are three main pillars of good indoor air quality that any airport, and buildings in general, should pay attention to:

Correct ventilation: It is important to have a good and well-maintained HVAC system that keeps adequate ventilation rates and fresh air intake from outdoors.

Filtration: This is how much of the outdoor pollutants are caught in the filters of the HVAC systems. The correct filtration is required, not so high that the system overheats, and not too low so that pollutants could pass through. In addition, the filters need to be replaced frequently allowing them to not get contaminated with dirt, moisture, or microorganisms.

Source control: Make sure that off-gassing products, such as cleaners, paints, building materials, furnishing, aerosols, etc., that could release harmful gasses like volatile organic compounds (VOCs), are not added into the facilities, and that no source emits VOCs in excess to the indoor environment.

Indoor Air Quality as a Key Aspect of Airport Passenger Experience

One of the main purposes of airports is to provide a positive and enjoyable commute experience. The main priority is keeping passengers safe and healthy during their whole experience. If passengers complain about the smell of jet fumes, having asthma, and/or allergy attacks due to poor indoor air quality, this immediately negatively impacts their commute experience.

Indoor Air Quality and Staff Productivity

There are many studies around air quality’s impact on health and productivity.

It is proven that having cleaner indoor air has numerous benefits including but not limited to maintaining a healthy respiratory system, improving cognitive performance, increasing productivity, and reducing the risk of cardiovascular disease.

A superior IAQ can increase worker’s productivity by 20%, according to Kimberly-Clark’s IAQ and Employee Productivity guide.

Increasing staff productivity can result in higher profit gains and a more enjoyable work environment.

Greener Spaces Improving Indoor Air Quality

By incorporating nature and making it visible in any building offers an attractive and clean feel, as shown by public health studies, it has beneficial results on employee health and stress.
