Whether in an office, a factory, a store, or a home, most work is conducted in buildings – and the vast majority of the world’s buildings are problematic. In the United States alone, buildings consume more than 68% of all electricity produced. Buildings also account for over 39% of America’s energy demands and are responsible for contributing 38% to the country’s total carbon dioxide emissions. Equally as unsettling, it’s not uncommon for indoor pollution levels to be two to five times higher (occasionally 100 times higher) than outdoor levels due to dust and fumes from interior building materials, cleaning solutions, production processes, central heating and cooling systems, radon gas, pesticides, paint, glue, carpets, and so on. In addition, buildingrelated productivity losses and illnesses resulting from toxins are estimated to cost businesses $60 billion annually. Eliminating these obstacles is therefore fundamental to the sustainability process. (Source: U.S. Environmental Protection Agency)
