 Ladies and gentlemen, can I ask you to sit down so that we can start the next session. And we're moving now straight into the world of design of architecture and urbanism. I was very interested yesterday to take down some notes that a lawyer, a technologist and an economist all mentioned the word architecture and urbanism and said one memory we said we don't have a chance in hell in getting cities to be smart unless we get the design of the architecture and the space right. So of course a theme that we heard in the last hour and a half in the previous session. Now Michael Kimmel, New York Times and I are going to be chairing this together in a very informal way and we have three of the most interesting I think designers and designers meant in really quite a wide sense here. Both of architecture and buildings but also systems and signs. I think all of that is part of our sense of the city and sense of the experience of the city which we want to talk about and we are intentionally going narrow. We're going to talk about making architecture, making systems and how people actually use them and react to them and try and get away from the issues of technologies per se but obviously go back to that in terms of what does that mean in terms of the new generation of design that confronts the architects and the designers of the 21st century. The three speakers we have are Alejandro Zair Apollo who is in fact quite recently made the Dean of Princeton School of Architecture in the States. He is very happy with the announcement that was made yesterday actually Richard because he set up his office here but bought his office here about 15 years ago, 12 years ago, 10 years ago so property values have gone up immediately as a result of that therefore it's not renting so he's going to stay or he's going to be renting it to others but Alejandro has been very much part of the London architectural scene and very international scene and a close colleague and friend of the urban age since its inception in fact was present and spoke at the very first conference we had in New York in 2005. Eric Spiekermann is one of the world's most talented designers, full stop. Everyone knows his work and doesn't really maybe know that his name is behind it which is always interesting. If you take the public transport in Berlin he designed the tube map there just think of that and he will show some of the other things that he's doing but most interesting why we've asked him to be here is to also talk about the interfaces between different components of design different elements, cars, smart cars and different systems and also as I say mapping itself and then Bjarke Engels who's just got off a plane from Sydney so we can forgive him everything everyone always gives Bjarke everything. Bjarke has come here from Sydney which is pretty impressive but otherwise hails from Copenhagen and there are two famous products from Denmark well maybe one or two more but Bjarke is one of them and the other one is Lego and he just told me that he was only informed the other day that he's actually going to be responsible for designing the Lego Museum and I think childhood dream so don't tell anyone but Bjarke has and you'll see from his work be very active not just in Europe but very recently in New York where he's opened a practice where some of the themes about effectively let's call it climate change more broadly but sort of environmental performance and technology at the heart of the work so we have three extremely interesting people to talk about these themes and I'm going to ask Alejandro to be the first to kick off thank you very much
