What is “Good IAQ?”

Because the state of indoor air quality within your facility consists of so many different factors involving both the building’s layout but also its location and HVAC infrastructure, creating a notion of what, “good IAQ,” is can be difficult.

If you suspect that there is an air pollution problem in your building, indoor air quality testing may be your first instinct. While air quality testing can be a valuable resource of insights, it is impossible to test for all pollutants at once. It can quickly become overwhelming and expensive.    

There is a complicated web of aspects that ultimately combine to form the indoor air quality conditions of your facility. A few signs of good IAQ in a building include having proper ventilation, appropriate temperature, and humidity levels, and being free of tobacco smoke, allergens, pathogens, and other biological contaminants. Your HVAC system should be in good condition, functioning correctly, and undergo regular maintenance to avoid becoming clogged, broken, or contaminated with build-ups like biofilms, fungi and mold.

Outdoor Air and the Building Envelope

Monitoring the many ways in which outdoor air enters your building is more complex than many think. Natural ventilation, HVAC systems and passive movement of air through what is known as the building envelope are just a few ways in which outdoor air moves in and around your facility.

A building envelope refers to the physical space that separates spaces that are ventilated or air conditioned from the spaces that lack the same ventilation or air conditioning. When a building is constructed, ensuring that the building envelope properly manages the transfer of heat and cooling is one of the elements that can have the largest ultimate impact on proper energy efficiency practices. A good building envelope infrastructure can offset the burden that is placed on the HVAC systems of the facility, even helping cool the building in warmer weather while simultaneously warming the building during colder weather.

Outdoor air enters and leaves a building via natural ventilation (I.E., opening windows and doors), through cracks and openings (I.E., spaces around windows or doors), and through the outdoor intake of your HVAC system, such as an outdoor-vented fan. 

Ensuring Clean Air

Additionally, you can subjectively tell if your air filters are working by inspecting it for clogs, ensuring that it fits properly, and asking your occupants who regularly suffering from cold or allergy symptoms if they noticeably feel better. 

Alternatively, our IAQ monitoring and management system, ECOSENSE Platforms, can provide you with a more objective answer as to whether your filtration is working. ECOSENSE Platforms creates reports covering over 15 unique indoor air quality data points and creates digestible reports that are available for viewing at public or employee-facing kiosks.
