The EcoCenter at Heron's Head Park is a green oasis in a heavily industrialized area on San Francisco's southern waterfront. The off-grid building serves as a venue for environmental justice education.
The EcoCenter is one of the most water efficient buildings in the world. A sophisticated treatment and recycling system uses a series of wetland "cells" to filter and purify wastewater, which is then used for landscape irrigation.
The living wall is the largest North American installation by French botanist Patrick Blanc. More than 4,000 plants were stapled into a cloth membrane, which is watered by a built-in irrigation system.
