5. “ . . . buildings are the biggest source of energy use and greenhouse gas emissions , which in turn impact the world’s climate changes.” Green Building: Essential Design Strategies for a Sustainable Future Barbara A. Nadel, FAIA, Architectural Record, November 2006
6. “ Global warming is not caused by natural forces beyond our control. . . . human beings are the cause of the problem. And so it is our responsibility to fix it.” An Inconvenient Truth Al Gore Total Energy Use
7. Oil Dependence The Middle East holds 61% of the world's proven oil reserves. North America has 5%.
8. Increasing Oil Demand Unless there is a dramatic effort to change our consumption, energy demand is expected to rise by nearly 20 percent by 2030 according to the Department of Energy. Source: Energy Information Administration
9. The amount of U.S. greenhouse gases flowing into the atmosphere , mainly carbon dioxide from burning fossil fuels, increased last year by 1.4 percent after a decline in 2006. Source: U.S. Energy Department Associated Press, 12/03/08
10. “ Carbon emissions have been growing at 3.5% per year since 2000 , up sharply from the 0.9 percent per year in the 1990s.” 02/15/09 EBN 09/09
12. Climate Change Quickens, Seas Rise Global warming is happening faster than expected and at worst could raise sea levels by up to 6-1/2’ by 2100 according to a group of scientists. November 24, 3009

24. Green buildings are good for the environment, people, and they provide life-cycle cost savings. The Bottom Line:
28. Drive Less Walk, bike, carpool or take public transportation more often. You’ll save one lb of CO2 for every mile you don’t drive. Your car will emit as much CO2 in a year as your entire household = 12,000 lbs.

45. Climate change will likely increase precipitation in some places while reducing it in others , particularly the West, where populations are growing the fastest. Environmental Building News, September 2008
46. “ Some experts say that water may be an even more challenging problem than energy in the coming decades . . . ” Environmental Building News, September 2008
55. Four independent, real-world studies . . . have all shown that sensor-activated faucets increase water use by anywhere from 30% to 100% . Sensor-activated flushes on toilets and urinals also increase water use, due mainly to “phantom flushes ”. Environmental Building News – April 2009

80. One-third or more of a building’s electrical consumption may go to lighting, and energy saved in lighting also reduces cooling loads. EBN April 2009 Replacing lamps, ballasts, luminaires, or all three, can lead to significant energy savings
81. Use colors of the same family to create tonal harmonies.
82. Changing a Light? Replacing one light bulb with a compact fluorescent light bulb will save 150 pounds of carbon dioxide a year The Energy Independence and Security Act of 2007 will phase out conventional incandescent lamps by 2014.
