Sustainability is the defining challenge • Buildings in U.S. – 41% of primary energy/carbon 73% of electricity, 34% of gas

• Buildings in China – 60% of urban building floor space in 2030 has yet to be built

• Buildings in India – 67% of all building floor space in 2030 has yet to be built 3 3

4th Paradigm –

The Science behind the Science • Empirical – guided by experiment/ observation – In use thousands of years ago, natural phenomena

• Theoretical – based on coherent group of principles and theorems

Tycho Brahe

Johannes Kepler

– In use hundreds of years ago, generalizations

• Computational – simulating complex phenomena – In use for decades

• Data exploration (eScience) – unifies all 3 – Data capture, curation, storage, analysis, and visualization – Jim Gray, free PDF from MS Research 7 7
