Peter Ensign, LEED AP BD+C, GRP – Executive Director
In the two years since Peter Ensign became executive director, DC Greenworks has emerged as the preeminent green roof installer and advocate for green infrastructure practices in the Washington, DC, metro region. Since he assumed leadership of DC Greenworks, green roof installations have surpassed 100,000 square feet, and the organization’s revenue has grown by 78 percent.
During this period, Ensign has overseen the installation of 53,566 square feet of green roofs, 1600 rain-barrel installations, the construction of several rain and native habitat gardens, and the largest rooftop farm in the District of Columbia. These activities have raised ecological awareness among more than 2000 residents, students and property owners, and trained 280 individuals in Green Infrastructure and its benefits – all while reducing stormwater runoff by 1.5 million gallons per year.
Ensign has served as a speaker and panelist on stormwater and green job training issues at conferences held by the US Environmental Protection Agency, Green Roofs for Healthy Cities, Bethesda Green, and Smithsonian Institution.
With more than 20 years of experience in architecture and construction project management, Ensign has developed and implemented design procedures, sales and marketing operations, and production systems for several design/build firms in the DC metro area.
During his career, Ensign participated in the restoration of waterways at Ridley Creek Park, PA; managed subdivision construction on the Central Oregon Coast; and currently joins neighbors in the annual cleanup of Sligo Creek in Silver Spring, Maryland.
