Al Gore's Nashville mansion is something of the energy-gobbler, while President Bush's Crawford ranch is more the model of responsible resource use. According to the Associated Press, the Gore's 10,000 square foot Belle Meade residence consumes electricity at a rate of about 12 times the average for a typical house in Nashville (191,000 kwh versus 15,600 kwh). While there are mitigating factors (further discussed in our article about the Gore household's energy use), this is still a surprising number, given that the residence is approximately four times the size of the average new American home.
In comparison the ranch home owned by George W. Bush in Crawford, Texas, was designed by Austin architect David Heymann, an associate dean for undergraduate programs at the University of Texas School of Architecture. While its precise size isn't known, scuttlebutt has it that it's about 4,000 square feet, all on one floor.
The Bush ranch utilizes an efficient geothermal heating and cooling system that pumps ground water through a heat exchanger to warm the house in the winter and cool it in the summer, a system that expends roughly one-quarter the energy of a conventional heater/air-conditioner. Water used by the house is reclaimed, treated, and reused, and rainwater funnels from the home's gutters into a large cistern, which holds the water for garden irrigation.
