Be sure to ask for healthy indoor air quality in your new home.

The materials used, the way the structure is built, and the heating, ventilation, and cooling systems all contribute to indoor air quality. So be sure to ask for healthy indoor air quality in your new home as it will impact the design in many ways.

Indoor air quality

There are common elements that impact indoor air quality. A fireplace is a leak in the building envelope. When there is a leak, it will either bring dirty air into the home or pull dirty air through the building envelope into the home. This also happens with restroom ventilation fans, crawl space, and duct work.

If the ductwork is not tight, it will actually spread dirty air around your house. Insulate it right and seal it tight.


The building envelope is critical in the design of a home with healthy indoor air quality. Keeping the air from moving through the walls will allow you to filter make up air through a filtration system. This will, along with a fresh air system, keep the air flowing through your house healthy and clean.

Also, and this one has big impacts to durability and indoor air quality, you have to keep the water out of the wall system. Water infiltration in your home will contribute to indoor air quality faster than anything else.


Finally, the materials used in your home impacts indoor air quality. Do the materials you use have VOC’s? What chemicals will they off gas into your air? Are they easy to clean? What do you use to clean the materials used? All of these questions impact indoor air quality and should be considered.



I know it is not going to be on the top of your list, but be sure to include healthy indoor air quality when you are building or renovating.
