Oscar Wilde wrote "all criticism is autobiography"; much the same can be said about choosing the best in green design and architecture, it may tell more about our preoccupations than anything else. Design is so subjective, and green design is even harder, given that it is so difficult to define. Is it green enough? Is it good enough? Where is the balance? Do we go safe or edgy? Old favourites or young up-and-comers? What kind of geographic diversity? We give it our best shot.
