Editor’s Note: This post is one of a series of technology spotlights that introduces common technologies used in U.S. Department of Energy Solar Decathlon team houses.
Good ventilation is vital for maintaining healthy indoor air quality.

As a result, odors, chemicals, particles, and humidity can become trapped, increasing indoor air pollution.
