I met Bill Dunster when he was working for Hopkins - interesting bloke. BedZED hasn't worked out as was hoped, yet it is a big step forward and has proved to many that you don;t have to live like Tom & Barbara inthe Goode Life to be green.
In answer to Paul's earlier question; In order to prove the 'green' credentials of a building, designers have to jump through a number of onerous hoops, which equates to higher fees, and up-front build costs. Now this isn't mandatory (yet). Aslo, many clients will only pay lip service to sustainability, and back away entirely once confronted with these 'extra' costs. While the long-term benefits of a sustainable approach are real, but it doesn't fit in with the "I want it now, and I want it cheap" culture. After all, sustainability doesn't show up on a balance sheet.
