Hungry Buildings

The energy-hungry buildings in the U-S

(source: 2007 Buildings Energy Data Book)

• Buildings now use 72 percent of all electricity and account for 80 percent of all electric expenditures.

• “Internal gains” account for as much as 27 percent of a home’s cooling load.

• There are now 113 million households in the US.

• One-third of all households rent their homes.

• The average new single-family home has increased in size by about 700 square feet since 1980.

• In 2006, 50 percent of all new homes completed were completed in the South. Cooling load management emerges as a priority.

• U.S. buildings carbon dioxide emissions (630 million metric tons of carbon) approximately equal the combined emissions of Japan, France, and the United Kingdom.

• Lighting uses more energy than cooling in the residential sector. This underscores the importance of breakthrough lighting technologies.

• As of 2006, the top five homebuilders hold 20 percent of the total market, the top 20 hold 35 percent, and the top 100 hold 47 percent.

• In 2001, lighting consumed 756 Billion kWh – America’s 104 nuclear generating units produced 769 billion kWh, while operating at a capacity factor of 89 percent. It took our entire nuclear fleet to illuminate America.
