For decades, scientists have been focused on outdoor air quality. Today, there are regulations in place across the U.S., and around the world, to help keep the atmosphere clean, and reduce smog and other pollution.
As the built environment in which we live our lives evolves and changes, so does the battle against mold and ques-tions loom about indoor air quality. While every state is different, California has some of the most intensive regulations in place for air quality control, creating the California Air Resources Board, which breaks the entire state down into 35 local air districts. Much of the push for cleaner air has come with a push for increased energy efficiency and less reliance on fuels and substances that can harm the atmosphere. Today, we are seeing a shift toward making buildings efficient as well for the sake of both the exterior and interior air quality.
