Forget your environmental footprint. Think about your ethical footprint. What good is it to build a zero-carbon, energy efficient complex, when the labor producing this architectural gem is unethical at best?

Treat the world like a failed state, then you can understand the players needed to fix it.

The fact that the president (Michelle Bachelet) was out giving minute-to-minute reports a few hours after the quake in the middle of the night gives you an indication of their disaster response.

When sustainability is viewed as being a matter of survival for your business, I believe you can create massive change.

When your focus is social change and not financial change why wouldn't you want to share that openly? Innovation only succeeds when it's shared. If you're a pioneer and you come up with something that can change the world and you turn round and say 'I'm not going to share this idea with anyone' then you only impact the few and not the many.

Ego gets you inches but it doesn't get you impact.

Some of the best work that's happening right now is from architects who have remained in their home countries and who have focused on a local or national identity and the idea of critical regionalism.
