TEANECK - One of the first "passive" home is being built in New Jersey and the owner says it will maintain a constant internal temperature, without heat or air conditioning.

The super energy-efficient pre-fabricated home in North Jersey is from Europe and is being built in Teaneck.

The concrete walls are 12-inches thick and the German-made windows are triple-paned.

"This house is unbelievable," says Paul Ganowski with Triton Construction. "It's going to hold a temperature of 70 degrees winter and summer, with no air conditioning and no heat."

The owner, who has been planning the home since 2009, also plans to add solar panels to the roof.
