Village Green Project

Village Green Logo

The Village Green Project was a community-based activityto demonstrate the capabilities of new real-time monitoring technology for residents and citizen scientists to learn about local air quality. The goal of the project was to provide the public and communities with information previously not available about their local air quality and engage communities in air pollution awareness. The project was conducted from 2013-2019.

A pilot station in Durham, North Carolina demonstrated the system’s ability to monitor several common air pollutants in real-time and make the data available online and by smartphone. The Village Green Project expanded to other communities across the U.S. to evaluate the station’s operation under different weather conditions and to increase awareness of this new community-based air quality monitoring system developed by EPA. The solar and wind powered station is a park bench structure with instruments that provide minute-to-minute air measurements for ozone, particle pollution and weather conditions.  

  • What does the Village Green station measure?

    The station is a park bench structure made from recycled materials and includes sophisticated instruments to measure two common air pollutants -- fine particle pollution called PM2.5 and ozone – and meteorological conditions such as wind speed, temperature and humidity. Weather conditions are important for understanding air quality. The third generation of the Village Green Station is housing 3 additional sensors to assess the performance of devices measuring black carbon, nitrogen dioxide (NO2) and total volatile organic compounds (tVOCs).

  • How do I access the data from the Village Green stations?

    The Village Green stations currently are operated by state and local agency partners to meet their local objectives. Please contact the state or local agency point of contact for data.

  • How does the Village Green station operate?

    A Village Green station contains air measurement instrumentation, miniaturized and low power computer technology, solar panels and communications equipment that is available to the public in the marketplace. The station is designed to wirelessly transmit data with automatic data quality checks in place. Powered by the sun and wind, Village Green stations can be sited in areas without access to power, transmit data wirelessly, and are designed to be easily located into a community environment.

  • How can the data be useful?

    Village Green station data is being used in research to improve understanding of air quality and to increase community awareness of local air quality conditions.

    Research studies tell us that local air pollution levels can be affected by pollution sources located both nearby and far away. For example, EPA’s near-road research has shown that pollution levels immediately downwind of a highway can be higher than in places farther from a highway. Lower cost air monitoring technologies, like the Village Green Project, can allow researchers and citizens to monitor local air quality to understand how air pollution varies from place to place.

    Beyond measuring the air and weather, the Village Green Project is also about engaging with neighbors in the immediate area about their environment and the public on the web. The station can be used as a community gathering place to learn about new technology, the environment, or simply to sit down and read a book.

  • Where are the Village Green stations located and who is participating?

    Houston, Texas

    Partner: The Houston Health Department, TX
    Station Location: John P. McGovern Museum of Health and Medical Science (The Health Museum), 1515 Hermann Dr, Houston, TX 77004
    Installation: March 2017

    The station, located outside The Health Museum, is the 3rd generation of the Village Green station. The station continues the advancement of research into next-generation air measurement technology by piloting three new sensors to detect and measure black carbon, nitrogen dioxide (NO2) and total volatile organic compounds (tVOCs).

    Durham, North Carolina

    Partner: Durham County, NC
    Station Location: Durham County South Regional Library, 4505 S. Alston Ave.
    Installation: June 2013

    The station, located outside the South Regional Library, is the Village Green station prototype and has been operating for public use since June 2013. The station is used for educational outreach activities with nearby schools, library programs for children and other patrons and for continued research on next-generation air measurement technology.

    Washington, DC

    Partner: District Department of the Environment
    Station Location: National Zoological Park, 3001 Connecticut Ave NW
    Installation: March 2015

    The Village Green Project station is located at the Smithsonian’s National Zoological Park.

    Kansas City, KS

    Partner: Kansas Department of Health and Environment
    Station Location: Kansas City South Branch Library, 3104 Strong Ave.
    Installation: March 2015

    The station is located outside the new Kansas City South Branch Library where it will be accessible to library visitors and others interested in learning about local air quality. This project stems from a growing interest in using new sensor technologies to learn more about air quality conditions and trends near schools, playgrounds, parks and neighborhoods.

    Philadelphia, PA

    Partner: City of Philadelphia’s Air Management Services
    Station Location: 6th and Arch Streets
    Installation: March 2015

    The station is located in Independence National Historical Park near the National Constitution Center.  This site was chosen because of its proximity to vehicle and pedestrian traffic. The real-time data generated by the site will be used to educate visitors and residents about street-level pollution exposure.

    Oklahoma City, OK

    Partner: Oklahoma Department of Environmental Quality 
    Station Location: Myriad Botanical Gardens, 301 W Reno Ave
    Installation: September 2015

    The station is located in the Children’s Garden of Myriad Botanical Gardens in downtown Oklahoma City.

    Hartford, CT

    Partner: Connecticut Department of Energy and Environmental Protection
    Station Location: Connecticut Science Center, 250 Columbus Boulevard
    Installation: November 2015

    The station is located outside of the Connecticut Science Center and near a major roadway.

    Chicago, IL

    Partner: Jane Addams Elementary School
    Station Location: Jane Addams Elementary School, 10810 S Avenue H
    Installation: March 2016

    The station is located at Jane Adams Elementary School, Chicago, IL.

    The site is down for maintenance until further notice. 

  • Are these measurements tied directly to air quality regulations?

    No – this is a research and educational air monitoring system using several lower cost instruments that are placed in an environment to involve the public (you!). The measurements should not be held up directly to official air quality standards, but can be explored to study how air pollution trends change with time and weather.

  • How can I build a Village Green Station?

    The Village Green stations are lower in cost and require less maintenance, but they are not off the shelf products that can be purchased by the general consumer. The system requires technical skills to build and some experience in air quality monitoring.

    A Village Green station combines a variety of commercially available components to function, including solar power and sometimes wind power, cellular communication, air measurement instruments, and meteorology instruments. In addition, a server handles the wirelessly transmitted data, conducts quality checks in real-time, and hosts the data on a website.
