What is a Healthy House?

Why Build a Healthy House?

Americans spend on average about 90% of their time indoors. As energy-conscious homes and office buildings are built more tightly and with better insulation, indoor air quality and proper ventilation have become important health issues. In some instances, the air indoors may be even more polluted than the outdoor air.

A dramatic increase in the incidence of asthma in our country over the last decade has been blamed, in part, on environmental factors. This has helped spark greater consumer interest in improving indoor air quality. Especially here in the environmentally-aware Pacific Northwest, families are looking for ways to create a healthier indoor environment.

American Lung Association® of Washington Healthy House projects:

• The Master Home Environmentalist^TM is a volunteer-driven program designed to help people learn more about health risks from pollutants in their home by conducting free home assessments.
• New Holly Healthy House (1998-99)
  A partnership effort with Seattle Housing Authority and Dr. Subrato Chandra, Florida Solar Energy Center, to incorporate healthy housing features in Holly Park, an affordable public housing development.
• Healthy House (1997)
  A demonstration Healthy House built by Finkbeiner Development and Cambridge Homes in Renton, Washington.

Criteria for Builders and Residents

Healthy House specifications are determined from site to site, building to building, based on four key principles: air-tightness for energy-efficiency; ventilation for fresh air and moisture control; source control for potential pollutants; and effective monitoring and maintenance.

These principles can be incorporated into new affordable construction as well as renovations, and can be maintained easily by the residents. These methods reduce exposure to common asthma and allergy irritants, such as dust mites, molds, mildew and volatile organic compounds (VOCs), like formaldehyde, acetone and toluene.
