DESCRIPTION
This presentation, which takes a typical city block in San Francisco and proposes a possible path to make it a place for local and sustainable living. The city block is transformed from typical inefficiency to Zero Impactthrough incremental solutions and strategies focusing on three levels of implementation across three different areas: Energy, Transportation and Water.This presentation won the 2008 Re:Volt Competition sponsored by Urban ReVision.
