DDOE and EPA Announce Unique Solar-Powered Park Bench Air Monitoring Station to Measure District's Air Quality

WASHINGTON DC, April 29, 2015—The District Department of the Environment (DDOE) and U.S. Environmental Protection Agency (EPA) announce the District’s new Village Green solar and wind-powered air monitoring station at the Smithsonian’s National Zoo. The station, which comes in the form of an innovative park bench, was developed by the EPA as a unique way to engage the public in measuring air quality and weather. The park bench station, loaned to DDOE by EPA, is located in the Kid’s Farm exhibit area of the Zoo.

The Village Green project puts science into the hands of residents and visitors, allowing them to access local air quality information from the park bench station through onsite displays and a smartphone-friendly website.  It provides real-time reliable readings on levels of fine particle pollution (also known as particulate matter), ozone, wind speed and direction, temperature, and humidity—all of which are important factors for understanding local air quality trends.Solar Air Monitoring Park Bench Station - Photo courtesy of EPA

“These new solar-powered air monitoring park benches provide minute-by-minute data that can help citizens better understand air quality,” said EPA Administrator Gina McCarthy.” Our EPA researchers used the latest science to build the air monitoring systems in park bench stations, empowering people to get involved and learn more about air quality in their neighborhoods and better protect their families."

To build the air monitoring systems, EPA researchers used air sensors, miniaturized and low-power computer technology, solar panels, and other instruments. In addition to providing environmental assessment tools, the bench is made from recycled materials. It includes a built-in monitoring station equipped with solar- and wind- powered components that charge a battery, which runs the entire system.
