Marc, today's charrette was terrific. Thank you for your truly generous collaboration. You've caused me to turn a mental corner. Until recently, I thought that that to do really intelligent buildings, we'd need the right clients, the right engineers, and a premium budget. Thanks to you, I now believe that to do intelligent buildings all we need is INTELLIGENCE!—and the guts to ask the simple questions until we get the answers, and the courage of our convictions to persuade others...

We can do this and it will change things. You've empowered us. Thanks. –Ellen
