Hi, have you ever heard of the term “passive house”. It seems that this expression is a translation of the German word Passivhaus which describes a building that doesn’t need any external heating source. As far as I can see, the “Passivhaus” concept is especially popular in Germany.
What about your country, do you have many “passive houses”?
Many thanks,

Of course, any way to save energy is good.
As I posted elsewhere, George W. Bush’s house in Texas is basically a “passive house”.

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 (usually 67 degrees F. ) 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.
