This seems to be a great event with speakerst like Matthias Adele Santos (MIT), Rudolf (Transsolar), Christoph Reinhart (MIT), Matt Noblett (Benisch Architekten). Unfortuantely I won’t be able to go:

Tentative Agenda (Link)

Over the next two decades, the United Nations expects that we need to plan, design and build new homes for 1.7 billion people. With buildings already accounting for some 40% of carbon emissions in many countries, the prospect of adding such titanic numbers to the built environment is worrisome. If we further add a 40% world-wide increase in transportation related carbon emissions, energy efficiency measures realized to date will be negated. There is an undeniable need for concepts and solutions that lead to more sustainable urban growth, concepts that work across a range of climates and cultures. What are those solutions? Are there good examples? How can we evaluate them on a large scale?
