Zero Energy Homes are the Homes of the Future. The most powerful trend in the real estate market today is the movement toward zero energy and zero energy ready homes. This is the case not just because these highly sustainable homes are a smart investment, but because they are the best homes on the market. Zero homes have no energy bills and net zero carbon emissions. They also use more advanced technology, are more durable, more quiet, more comfortable, and healthier to live in than standard homes.
