Buildings use a lot of energy
1/3 of all energy and 2/3 of all electricity used in the US$220 billion in annual energy costsSource: US Department of Energy

Energy is the Defining Challenge of Our Time
• Buildings in U.S.– 40% 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
Global energy consumptionwill increase 50% by 2030
“Upgrading the energy efficiency of America’s buildings is one of the fastest, easiest, and cheapest ways to save money, cut down on harmful pollution, and create good jobs…” President Obama,
December 2, 2011, while announcing Better Buildings Challenge
