Did you know that indoor air can be three to four times more polluted than the air you breathe outside? Poor indoor air quality can result in asthma, allergies, stuffy nose, headaches and fatigue caused by things such as dust mites, hair, mould and gasses from building materials, furnishings, cleaning products and heating systems.

 

Indoor air quality is a growing concern in homes and businesses. As energy efficiency increases, other problems can sometimes be created.

All buildings, particularly newer, more airtight homes, require ventilation to get rid of stale air and indoor toxins, and eliminate excess moisture.

 

Today's energy-efficient homes are so tight that they virtually eliminate all air leaks. Good for your heating bill, but bad for your health — recirculating stale air contains a build-up of pollutants, odours, carbon dioxide and excessive moisture.

It's important to think of your house as an integrated system, with everything in your home functioning cooperatively towards good indoor air quality and energy efficiency.

 

Proper building techniques and appropriate mechanical ventilation can help resolve indoor air quality problems while meeting energy code requirements.
