Envelope Integrity

A Healthy Home is a home with a sustainable indoor environment. There are several different factors that contribute to the total indoor environment, including adequate ventilation, appropriate humidity levels, air filtration and building envelope integrity.

"A balance is maintained by making sure a home has positive exterior drainage away from the house in all directions, a properly sized heating and cooling system, vapor diffusion protection, as well as adequately planned ventilation." -Healthy Indoor Air for America's Home

Maintaining the integrity of the building envelope is probably the most misunderstood part of creating a healthy indoor environment. Most people do not associate good exterior drainage and properly sized HVAC equipment with the air that they breathe. But if moisture is migrating into the foundation of your home or into the crawlspace, then that moisture will migrate up into your living spaces as well. And an oversized HVAC system can cool floors and furniture to a dewpoint level, creating a moisture problem that doesn't need to be there. By preventing excessive moisture in and around the home, you can create a healthier breathing environment.

The HealthyAir DVA system combines dehumidification, air filtration and fresh air ventilation into one system that will help create a healthy and sustainable indoor environment for your family. By combining these three methods, most indoor allergens and toxins can be effectively removed. Although the HealthyAir DVA cannot maintain the integrity of the building envelope, it does add positive pressure to the indoor space, which helps prevent the migration of moisture, mycotoxins from mold and VOCs.
