Solar Decathlon. Net Zero House stays at 70 when below zero outside


Heating costs are expensive in New England. Students at Norwich University in Vermont have designed an affordable 2 bedroom 1 bath home with net zero energy use that will stay at 70 degrees even if it’s minus 20 outside. Wow.

The Solar Decathlon features homes designed and built by college students using solar power, and are judged on ‘consumer appeal, and design excellence with optimal energy production and maximum efficiency.”

The solution is designed to maintain an interior temperature of 70 degrees Fahrenheit, even when outside temperatures drop to 20 degrees below zero, all while achieving net zero energy usage.


  1. I love the idea, living in Vermont as I do.
    But that’s a flat roof.
    AND it’s an uneven roof.
    So what happens when it snows???
    The video shows snow on the ground and
    a clean roof with nary an icicle!
