  14. 14. Benefits for Sustainability Nancy Yen-wen Cheng Facilitates •  Integrated practice •  More seamless performance modeling •  Post-occupancy monitoring & responsiveness Image courtesy of Turner Construction
  15. 15. Sustainability requires integrated practice Nancy Yen-wen Cheng •  More stakeholders involved in design earlier •  Shared risk & rewards: Your success depends of success of others –Michael Hricak •  Cultural Transformation needed.

  16. 16. Integrated Practice Nancy Yen-wen Cheng •  One aspect affects all others. Adding mass for a thermal flywheel effect would have triggered a seismic upgrade. As soon as you did something to the flooring, suddenly it wasn't just that cost, but it was the next cost, the next cost. So that was the early design process: dead end, let's back up, let's go this way, try again." - Mark Heizer, Interface Engineering Diana Fischetti
