As part of the national campaign to grow industry and consumer awareness for healthy living, the American Lung Association embarked on the design, construction, and promotion of demonstration Health Houses. Beyond inherent qualities such as high indoor air quality and energy efficiency, this project is unique in that two one-story houses are built side-by-side, representing the same floor plan constructed of different materials and conditioned by different fuel-types. Such an approach demonstrates that a healthy home is not dependent on any given material, method, or fuel. Opened to the public in 1999 in Tucson, IBACOS served as the technical advisor, and quality control and performance review agent for the ALA on both houses.
