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 ALONE. This mansion consumes more energy than the average American household in an ENTIRE YEAR. The average bill for electricity and natural gas runs over $2,400.00 per month. In natural gas alone (which last time we checked was a fossil fuel), this property consumes more than 20 times the national average for an American home. This house is not located in a northern or Midwestern “snow belt,” either. 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 contains only 4,000 square feet (4 bedrooms) and is nestled on arid 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 (usually 67 degrees F.) heats the house in winter and cools it in summer. The system uses no fossil fuels such as oil or natural gas, and it consumes 25% of the 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. Flowers and shrubs native to the area blend the property into the surrounding rural landscape.
