Via zerochampion, the Guardian’s architecture commentator suggests that buildings
…should only really be offered prizes 20 years after their completion. While we can comment on the merit of the design, look and feel of a particular building when new, and celebrate the intentions of its designers, there is no guarantee that it might not prove to be a failure.
I know we ought to be happy that architecture is being discussed on TV at all. Having said that, if I were in charge of the Stirling Prize I’d consider actual measured energy use and give occupants a vote on whether they think the building is a success.
