Ventilation and Indoor Air Quality

Improving Ventilation and IAQ

There is more to conditioning your indoor space than just heating or air conditioning. Keeping your indoor air fresh, clean, and at a comfortable humidity level are also key contributors to your health and comfort. New changes in building codes are addressing some of these concerns, particularly with new construction. Your 21 Degrees consultant will walk you through your options, and help you make good decisions about the air quality in your indoor environment. 


IAQ stands for indoor air quality.  Generally, IAQ refers to the quality of the indoor air, particularly with concern to how the indoor air affects the health and comfort of the people in the space. This can include factors such as humidity, temperature, contaminants in the air, and the introduction or lack of outside air. 


Ventilation refers to providing fresh air to an indoor space, or the exchange of indoor and outdoor air. Ventilation is key to healthy IAQ. Without proper ventilation, an indoor space may become contaminated by trapping in both harmful pollutants, which can be harmful to the occupants' heath, and moisture, which can cause damage to property and promote the growth of contaminants such as mildew and mold. Good ventilation helps keep your indoor space efficient and healthy.

There are many ways to control and improve your indoor air quality. Two of the most common ways we help control indoor air quality, both in commercial and residential environments, are with advanced filtration and heat recovery ventilation (HRV's).
