9. I've never heard of a building with auto exposure
before. Great idea! Looks like a lot of moving parts -
- an engineering nightmare -- hope it doesn't break
too often!

23. From 1900 to 2000 human numbers
increased four fold – from 1.5 to 6
billion
Resource consumption and urban
populations went up sixteen fold
Every year we burn at least one
million year’s worth of fossil fuels
Cities, on 3-4% of the world’s land
surface use 80% of its resources, and
discharge most solid, liquid and
gaseous waste

31. Sustainable energy for cities
•Solar technology can produce 200 times
more energy per surface area than photo-
synthesis.
•Intra-urban: solar thermal, PV and CHP plus
energy efficiency.
•Suburban: turning the suburb into a solar
power station.
•Ex-urban: Large scale solar plus on- and
off-shore wind farms.
