The theme for world expo 2010 in China is "Better City, Better Life". A chance to see some really cool pavilion designs that are hopefully also sustainable. Foster + partners recently revealed their sand dunes inspired design for the 32,000 SF UAE pavilion. So far the only significant sustainable 'feature' I'm aware of is that the building will be dismantled and moved back to Dubai to be reused as a cultural center.
I guess moving it somewhere closer would have been more sustainable- like the Finland pavilion below, which is planned to be dismantled and moved somewhere in China to be used as a restaurant, office building or library.
There are a lot of interesting designs from different countries displayed on the expo website. Expos are really good for bringing very creative ideas to reality. All designs look impressive but it makes me think if green buildings should look 'green'. especially when they are designed for public consumption like this expo. Take a look at the Swiss expo design with a rooftop 'grassland' and outside curtains made of bio-degradable soybeans and dye-sensitized solar cells
to generate electricity.
China is expecting some 70 million visitors for the expo and I guess most of them will be local. That's a really good opportunity to showcase 'sustainability' because if China goes the US way we are screwed.
