House #1 A 20 room mansion (  not including 8 bathrooms ) heated by
natural gas. Add on  a pool ( and a pool house) and a separate guest
house, all heated by gas.  In one month this residence consumes more 
energy than the average American household does in a  year.  The
average bill for electricity and natural gas  runs over $2400.  In
natural gas alone, this property consumes more  than 20 times the
national average for an American home.  This house is not situated
in a Northern or Midwestern "snow belt" area. It's in the South.   
 

 

                                
 

 

House #2 Designed by an architecture professor at a leading national university.  This house incorporates every "green" feature current home construction can provide.  The house is 4,000 square feet (4 bedrooms) and is nestled on a high prairie in the American southwest.  A central closet in the house holds geothermal heat-pumps drawing ground water through pipes sunk 300 feet into the ground. The water is usually 67 degrees F and heats the house in the winter and cools it in the summer.  The system uses no fossil fuels such as oil or natural gas and it consumes one-quarter electricity required for a conventional heating/cooling system.  Rainwater from the roof is collected and funneled into a 25,000 gallon underground cistern.  Wastewater from showers, sinks and  toilets goes into underground purifying tanks and then into the  cistern.  The collected water then irrigates the land surrounding the house.   Surrounding flowers and shrubs native to the area enable the property to blend into the  surrounding rural landscape.
