1. Strategic Integration and Automation of Conceptual Design Haymaker, Law, Gane, Flager, Shkolnik CIFE Research Proposal Architecture Engineering Computer Sciences April 26, 2007

2. The economic and environmental impacts of buildings in the U.S.: Research Motivation Energy Raw materials Key Total building consumption Impact determined by initial design Best practice reduction 35% buildings 30% buildings (USGBC, 2007) Can we do better? Strategic Integration and Automation of Conceptual Design

3. Limitations of Current Practice We have the tools: • schedule constraints→ limited use in conceptual design • current methods→ few options generated & analyzed Strategic Integration and Automation of Conceptual Design 3
