I don’t think sustainability is a design aesthetic, any more than having electricity in your building, or telephones, or anything else, says Stern. It’s an ethic, a basic consideration that we have to have as architects designing buildings. Stern argues in 10 years we’re not going to talk about sustainability anymore, because it’s going to be built into the core processes of architecture. Advertising sustainability, he says, will be like an architect getting up in front of a room to proudly proclaim how his buildings didn’t fall down.
