Improving Indoor Air Quality with Plant-Based Systems
Improving Indoor Air Quality with Plant-Based Systems By B. C. “Bill” Wolverton, Ph.D. (Ret. NASA) Wolverton Environmental Services, Inc. (WES) Introduction In the United States (U.S.), energy consumption has continually spiraled upward. This increased demand for energy has resulted in energy costs also rising. As a result, the building industry strives to tightly seal buildings to conserve energy. According to the U.S. Department of Energy and the U.S. Green Building Council, commercial and residential buildings account for more than 60 percent of the total electrical consumption in the U.S. When buildings are tightly sealed, a buildup of human bioeffluents, airborne microbes and volatile organic chemicals (VOCs) often leads to poor indoor air quality. In 1989 the U.S. Environmental Protection Agency (EPA) submitted a report to the U.S. Congress on the quality of air found inside energy efficient public buildings. The study included offices, hospitals, nursing homes and schools. This report stated that more than 900 VOCs were identified that may pose serious acute and chronic health problems to individuals who live and work inside these buildings. Even though it is important to reduce energy costs, there are other health-related savings that should be stressed as well. According to studies conducted more than ten years ago at the Lawrence Berkley National Laboratories by Dr. William J. Fisk and Dr. Arthur H. Rosenfeld, companies in the U.S. can save as much as $58 billion annually by preventing sick building illness. An additional $200 billion savings in worker performance could be realized by creating buildings with better indoor air quality. -
