The mission of his practice is to design sustainable human environments. He has been closely involved in the leadership in to create LEED ND. Some of their developments include Lake Pulaski Transit Oriented Development (TOD) 1998 on the west side of Chicago. In 1999 they produced the first LEED platinum building, the Chicago Centre for Green Technology. “Urbanism did not come up at all in the first LEED standards” and there was no mention of building around transit. It was basically a systems integration approach – heating, lighting ,waste water and so on. Most clients really did not see the need: for instance at Orland Park TOD they were told to “remove the green stuff”.
