Air Quality

Why the big concern now about indoor air quality (IAQ), is the air quality worse now that it was in the past?

IAQ did not used to be a big problem. This is because before the 1970’s, there were almost no energy conservation rules and regulations for buildings and homes. Much of this changed in an effort to conserve heat and cold losses in buildings, and ultimately conserve more energy and cut costs.

Structures began to be built more tightly, with better windows, and improved seals. This resulted in less natural air circulation.

The Sick Building Syndrom (SBS) entered into our culture during that time.
