Although achieving "net zero" may not be practical for our budget during construction, simple photovoltaic electric systems can satisfy the everyday electrical demands of a Passivhaus. Can you imagine producing your own energy thus seperating yourself from the power grid?!
I may stand corrected; however, I believe GO Logic Homes, out of Belfast, Maine, was recently featured on DIY Network's "This New House - Why Passive Houses Rock." The show featured a recently built 1500 square foot net-zero certified Passivhaus. The video below showcases the efficient layout of this home.
