Earlier this week, on February 3, 2011, President Barack H. Obama stopped by at Penn State to present his Energy Innovation Hub plan encompassing three university–industry–government partnerships. One of the three aims is to significantly improve the energy efficiency of buildings—from single-family dwellings to skyscrapers—in the United States. “Now, that may not sound too sexy: energy-efficient buildings,” Obama said to some laughter, but, as the built environment is responsible for 40% of the energy consumption in the country, he estimated that US businesses could save nearly US $40 billion a year by reducing their energy consumption. In the bargain, the adverse effects of energy generation and distribution on the natural environment would also be lessened.
