1. Presentation to WRI-UNEP Meeting Building Connections for Sustainable Building And Construction by Iddo Wernick October 2, 2003

2.  Focus on Mass Flows  More Generally, Large Scale Measures of Environment & Resources  Seek Patterns/Opportunities in Societal Resource Use Industrial Ecology

3. Bulk & Specialized Mass Flows Strategies  Recovery  Substitution  Design
