The EcoCenter's living roof was part of the Cities Alive Conference today. The conference is put on by Green Roofs for Healthy Cities. About 30 participants from all over the world toured some of the City's most beautiful living rooftops and walls and the EcoCenter's roof was one of the first stops. Awie Smit who was one of the principal builders of the living roof at the EcoCenter lead the tour/discussion of the rooftop and Peggy and CCSF student interns gave a tour of the facility.
