Keeping a Healthy Home

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 the maintenance of the integrity
of the building envelope.
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.
