In striving to construct energy-efficient, cost-effective buildings, the imperative issue of their indoor air quality (IAQ) is often overlooked. This can lead to an unhealthy indoor environment and to conditions such as sick building syndrome (SBS) or other building related illnesses (BRI).
In the past few decades, energy conservation measures have led to airtight building construction that can create problems with IAQ. Frequently, the ventilation systems are set to minimize the amount of fresh air entering and circulating within the facility. This restriction impacts indoor air, allowing a buildup of air contaminants within the structure that are not properly removed.
