New techniques in air sealing have created improvements in household energy efficiency. However the growth in the number of tightly sealed homes has increased the need for proper ventilation strategies.
Exchanging indoor air with outdoor air, also known as ventilation, is essential for maintaining good indoor air quality. Without adequate ventilation, chemical contaminants such as radon, volatile organic compounds, and formaldehyde can build up in your home. In addition to chemicals, other particles such as dust, bacteria, mold, viruses, and allergens will also not be able to escape. Even your everyday activities like cooking and cleaning can create particles and odors that should be flushed out with proper ventilation.
Indoor moisture is another concern that can be addressed with a good ventilation system. Water vapor in indoor air can increase the growth of mold and fungus, and may cause other damage to your home and furnishings. You always try to attack the source problem for all these problems, but bringing fresh air in and eliminating old, stale air will help mitigate this problem, too.
There are a number of ways to tackle ventilation problems. Natural ventilation through cracks, holes, and other leaks is common in older homes, but newer or tightly sealed homes do not typically allow this, which is why it is important to be proactive.
Spot ventilation is another common way to remove stale indoor air. Typical examples include bathroom or kitchen exhaust fans that you can turn on as needed. One disadvantage is that the exhaust fans also remove conditioned air from your home, which can make your heating and air conditioning system run more often. Spot ventilation works best in combination with a larger system.
Whole-house ventilation systems work with your existing duct system to remove old air and bring in fresh, outdoor air. Because they use the blower from your home comfort equipment, whole-house ventilators are a very energy efficient way to provide ventilation throughout your entire home.
