A healthy living environment

With the goal of preventing heat loss through gaps and cracks, many new homes today are almost hermetically sealed. However, this often results in poor ventilation and can create indoor air-quality problems, including mold and unpleasant odors. Opening windows obviously improves ventilation, but defeats the purpose of sealing the home to prevent heat and energy loss. Besides that, opening windows allows noise, insects, soot and airborne pollen to come in to the home, and can also cause drafts.
